+*Screenshot placeholder: DOS screen showing complete boot process with all status messages*
+
+**Boot time:** Approximately 2-3 minutes (depending on updates)
+
+---
+
+### What Happens During Boot
+
+**Step-by-step breakdown:**
+
+1. **DOS starts** (5 seconds)
+ - Loads CONFIG.SYS
+ - Runs AUTOEXEC.BAT
+
+2. **Network starts** (30 seconds)
+ - Loads Microsoft Network Client
+ - Maps T: drive to \\D2TESTNAS\test
+ - Maps X: drive to \\D2TESTNAS\datasheets
+
+3. **NWTOC downloads updates** (30-60 seconds)
+ - Checks T:\COMMON\ProdSW for new batch files
+ - Checks T:\TS-XX\ProdSW for machine-specific files
+ - Downloads only newer files (smart update)
+ - Creates .BAK backups of replaced files
+
+4. **CTONW uploads test data** (30-60 seconds)
+ - Uploads batch files from C:\BAT to network
+ - Uploads programs from C:\ATE to network
+ - Uploads test data (.DAT files) to LOGS folder
+
+5. **System Ready**
+ - Displays command prompt
+ - Ready for testing
+
+**Total time:** 2-3 minutes
+
+---
+
+## Initial Deployment
+
+### When to Run Deployment
+
+**Run deployment on:**
+- Brand new DOS machine
+- Reformatted machine
+- Machine without automatic updates
+
+**Do NOT run deployment on:**
+- Machines already deployed (unnecessary)
+- Machines that auto-update on boot (already deployed)
+
+---
+
+### Deployment Procedure
+
+**Follow these steps exactly:**
+
+#### Step 1: Boot Machine
+- Power on DOS machine
+- Let it fully boot to C:\> prompt
+- Verify network drives mapped (T: and X:)
+
+![Screenshot: DOS Prompt Ready]
+*Screenshot placeholder: DOS C:\> prompt with machine name displayed*
+
+#### Step 2: Verify Network Access
+Type:
+```
+DIR T:\
+```
+
+You should see:
+```
+COMMON
+TS-01
+TS-02
+...
+```
+
+![Screenshot: T Drive Contents]
+*Screenshot placeholder: DOS DIR T:\ output showing COMMON and TS-XX folders*
+
+If you see "Invalid drive" or error, see [Troubleshooting: Network Not Available](#network-not-available)
+
+#### Step 3: Run Deployment Command
+Type (replace XX with your machine number):
+```
+T:\UPDATE.BAT TS-04
+```
+
+**Important:**
+- Use your actual machine number (TS-01 through TS-30)
+- Type exactly as shown (uppercase)
+- Press Enter
+
+![Screenshot: Running UPDATE.BAT]
+*Screenshot placeholder: DOS screen showing T:\UPDATE.BAT TS-04 command being entered*
+
+#### Step 4: Watch Deployment Progress
+You'll see:
+```

+
+#### Step 7: Reboot
+**Press Ctrl+Alt+Del to reboot**
+
+After reboot:
+- Automatic updates enabled
+- No manual commands needed
+- Ready for testing!
+
+---
+
+### Verifying Deployment Successful
+
+**After reboot, check for:**
+
+1. **Network drives mapped:**
+ ```
+ DIR T:\
+ DIR X:\
+ ```
+ Both should work without errors
+
+2. **Batch files installed:**
+ ```
+ DIR C:\BAT
+ ```
+ You should see: NWTOC.BAT, CTONW.BAT, UPDATE.BAT, etc.
+
+3. **Machine name set:**
+ ```
+ ECHO %MACHINE%
+ ```
+ Should show: `TS-04` (or your machine number)
+
+4. **Automatic updates ran:**
+ - Boot screen showed "Checking for software updates..."
+ - Boot screen showed "Uploading test data to network..."
+ - Both completed with [OK] messages
+
+**If all checks pass: Deployment successful!** ✅
+
+---
+
+## Understanding the Boot Process
+
+### What Each Component Does
+
+#### AUTOEXEC.BAT
+- **Location:** C:\AUTOEXEC.BAT
+- **Runs:** Every boot (automatically)
+- **Purpose:** Machine startup configuration
+- **What it does:**
+ 1. Sets machine identity (MACHINE=TS-04)
+ 2. Sets DOS path and environment
+ 3. Starts network client
+ 4. Calls NWTOC (download updates)
+ 5. Calls CTONW (upload test data)
+ 6. Displays "System Ready"
+
+**You never need to edit or run this manually.**
+
+---
+
+#### NWTOC.BAT (Network to Computer)
+- **Location:** C:\BAT\NWTOC.BAT
+- **Runs:** Automatically during boot (called by AUTOEXEC.BAT)
+- **Purpose:** Download software updates from network
+- **What it downloads:**
+ - Batch files: T:\COMMON\ProdSW → C:\BAT
+ - Programs/Config: T:\TS-XX\ProdSW → C:\ATE
+ - System files: T:\COMMON\DOS → C:\ (staged for reboot)
+
+**Manual use:** Only if you need updates without rebooting (see [Manual Operations](#manual-operations))
+
+---
+
+#### CTONW.BAT (Computer to Network)
+- **Location:** C:\BAT\CTONW.BAT
+- **Runs:** Automatically during boot (called by AUTOEXEC.BAT)
+- **Purpose:** Upload test data and local changes to network
+- **What it uploads:**
+ - Batch files: C:\BAT → T:\TS-XX\ProdSW
+ - Programs: C:\ATE → T:\TS-XX\ProdSW
+ - Test data: C:\ATE\*DATA → T:\TS-XX\LOGS (for database import)
+
+**Manual use:** If you need to upload data without rebooting
+
+---
+
+#### UPDATE.BAT
+- **Location 1:** T:\UPDATE.BAT (network shortcut)
+- **Location 2:** C:\BAT\UPDATE.BAT (backup utility)
+- **Purpose:** Two different functions depending on location
+
+**T:\UPDATE.BAT (Deployment):**
+- Runs DEPLOY.BAT for initial setup
+- Usage: `T:\UPDATE.BAT TS-04`
+- Use once per machine (initial deployment)
+
+**C:\BAT\UPDATE.BAT (Backup):**
+- Creates full system backup to T:\TS-XX\BACKUP
+- Usage: `C:\BAT\UPDATE.BAT`
+- Use before major changes
+
+---
+
+#### CHECKUPD.BAT
+- **Location:** C:\BAT\CHECKUPD.BAT
+- **Purpose:** Check what updates are available without downloading
+- **Usage:** `C:\BAT\CHECKUPD`
+- **Shows:**
+ - Available batch file updates
+ - Available system file updates (AUTOEXEC.NEW, CONFIG.NEW)
+ - Available machine-specific updates
+
+**Use this to see what will download on next reboot.**
+
+---
+
+#### STAGE.BAT & REBOOT.BAT
+- **Location:** C:\BAT\STAGE.BAT, C:\BAT\REBOOT.BAT
+- **Purpose:** Apply system file updates (AUTOEXEC.BAT, CONFIG.SYS)
+- **When used:** Automatically when AUTOEXEC.NEW or CONFIG.NEW detected
+
+**Process:**
+1. NWTOC finds AUTOEXEC.NEW on network
+2. NWTOC calls STAGE.BAT
+3. STAGE.BAT creates REBOOT.BAT
+4. Screen prompts: "Reboot required"
+5. You run: `C:\BAT\REBOOT.BAT`
+6. System reboots
+7. REBOOT.BAT applies new AUTOEXEC.BAT
+8. New configuration active
+
+---
+
+## Manual Operations
+
+### When Manual Operations Needed
+
+**Normally:** No manual operations required (automatic updates handle everything)
+
+**Manual operations needed when:**
+- Urgent update can't wait for reboot
+- Testing new batch file immediately
+- Checking for available updates
+- Troubleshooting update issues
+- Creating full system backup
+
+---
+
+### Manual Update Check
+
+**To see what updates are available:**
+
+```
+C:\BAT\CHECKUPD
+```
+
+**Output shows:**
+```
+==============================================================
+Update Check: TS-04 from Network
+==============================================================
+
+[1/3] Checking T:\COMMON\ProdSW for updates...
+ [FOUND] 2 newer batch files available:
+ NWTOC.BAT (2026-01-19 vs 2026-01-15)
+ CTONW.BAT (2026-01-19 vs 2026-01-15)
+
+[2/3] Checking T:\TS-04\ProdSW for machine-specific updates...
+ [SKIP] No machine-specific directory
+
+[3/3] Checking for system file updates...
+ [OK] No system file updates
+
+==============================================================
+Summary: 2 updates available
+==============================================================
+
+To download updates: C:\BAT\NWTOC
+Or wait for next reboot (automatic download)
+```
+
+![Screenshot: CHECKUPD Output]
+*Screenshot placeholder: DOS screen showing CHECKUPD results with 2 updates available*
+
+---
+
+### Manual Update Download
+
+**To download updates immediately (without rebooting):**
+
+```
+C:\BAT\NWTOC
+```
+
+**What happens:**
+- Downloads all available updates
+- Creates .BAK backups of replaced files
+- Updates ready to use immediately
+- No reboot required (unless system files)
+
+**When to use:**
+- Engineer says "urgent update available"
+- Need new feature immediately
+- Troubleshooting batch file issue
+
+![Screenshot: Manual NWTOC]
+*Screenshot placeholder: DOS screen showing NWTOC downloading updates manually*
+
+---
+
+### Manual Data Upload
+
+**To upload test data immediately (without rebooting):**
+
+```
+C:\BAT\CTONW
+```
+
+**What happens:**
+- Uploads batch files from C:\BAT
+- Uploads programs from C:\ATE
+- Uploads test data (.DAT files) to LOGS
+
+**When to use:**
+- Just finished test run
+- Need data in database immediately
+- Sharing modified batch file with engineering
+
+---
+
+### Manual Full Backup
+
+**To create complete system backup:**
+
+```
+C:\BAT\UPDATE
+```
+
+**What it backs up:**
+- C:\BAT\* → T:\TS-XX\BACKUP\BAT\
+- C:\ATE\* → T:\TS-XX\BACKUP\ATE\
+- C:\AUTOEXEC.BAT → T:\TS-XX\BACKUP\
+- C:\CONFIG.SYS → T:\TS-XX\BACKUP\
+
+**When to use:**
+- Before major system changes
+- Before deploying new AUTOEXEC.BAT
+- Monthly backup routine
+- Before reformatting machine
+
+**Backup location:** `T:\TS-04\BACKUP\` (or your machine number)
+
+---
+
+### Applying System File Updates
+
+**If you see message: "Reboot required for system updates"**
+
+**Steps:**
+
+1. **Save your work** (close all programs)
+
+2. **Run reboot script:**
+ ```
+ C:\BAT\REBOOT
+ ```
+
+3. **Watch the screen during reboot:**
+ - You'll see: "Applying system updates..."
+ - REBOOT.BAT copies staged files
+ - System reboots again automatically
+
+4. **After second reboot:**
+ - New AUTOEXEC.BAT or CONFIG.SYS active
+ - System ready for testing
+
+**Don't worry if you see two reboots - this is normal for system file updates.**
+
+---
+
+## Troubleshooting
+
+### Network Not Available
+
+**Symptom:**
+- Error: "T: drive not available"
+- Error: "Invalid drive specification"
+- Network drives not mapped
+
+**Solution:**
+
+#### Step 1: Check Network Cable
+- Verify Ethernet cable connected
+- Check for link light on network port
+
+#### Step 2: Restart Network Client
+```
+C:\NET\STARTNET
+```
+
+Wait 30 seconds, then try:
+```
+DIR T:\
+```
+
+#### Step 3: Check T: Drive Mapping
+```
+NET USE
+```
+
+Should show:
+```
+T: \\D2TESTNAS\test
+X: \\D2TESTNAS\datasheets
+```
+
+If missing, network start failed. Contact IT.
+
+---
+
+### Updates Not Downloading
+
+**Symptom:**
+- Boot shows: "[OK] No new batch files in COMMON"
+- But engineer says updates were deployed
+
+**Possible Causes:**
+
+#### Cause 1: Updates Not Synced Yet
+**Solution:** Wait 15-20 minutes, then reboot again
+
+Engineers place files on AD2, which syncs to NAS every 15 minutes. If you reboot too soon, NAS doesn't have new files yet.
+
+#### Cause 2: DOS Clock is Wrong
+Check date/time:
+```
+DATE
+TIME
+```
+
+If DOS clock is in the future, XCOPY thinks network files are "older" and skips them.
+
+**Solution:** Set correct date/time:
+```
+DATE 01-19-2026
+TIME 14:30:00
+```
+
+Then reboot or run:
+```
+C:\BAT\NWTOC
+```
+
+#### Cause 3: Files in Wrong Location
+Verify file exists on network:
+```
+DIR T:\COMMON\ProdSW\FILENAME.BAT
+```
+
+If missing, contact engineering - file not synced or wrong location.
+
+---
+
+### Boot Takes Too Long
+
+**Symptom:**
+- Boot process takes 5+ minutes
+- Machine seems stuck
+
+**Normal boot time:** 2-3 minutes
+
+**If longer:**
+
+#### Step 1: Check Network Status
+During boot, watch for:
+```
+Starting network client...
+```
+
+If this hangs for minutes:
+- Network issue (cable, switch, NAS down)
+- Press Ctrl+C to skip network start
+- Contact IT
+
+#### Step 2: Check Update Status
+If stuck at:
+```
+Checking for software updates...
+```
+
+Possible causes:
+- Large files downloading (be patient)
+- Network congestion (wait or reboot later)
+- T: drive issue (see [Network Not Available](#network-not-available))
+
+#### Step 3: Skip Automatic Updates (Emergency Only)
+If you need to bypass auto-updates to start testing:
+
+**Edit AUTOEXEC.BAT temporarily:**
+```
+EDIT C:\AUTOEXEC.BAT
+```
+
+**Comment out NWTOC and CTONW lines:**
+```batch
+REM Temporarily disabled for troubleshooting:
+REM IF EXIST C:\BAT\NWTOC.BAT CALL C:\BAT\NWTOC.BAT
+REM IF EXIST C:\BAT\CTONW.BAT CALL C:\BAT\CTONW.BAT
+```
+
+**Save and reboot**
+
+**Important:** This is temporary only. Contact engineering to fix root cause.
+
+---
+
+### "Invalid Path" or "File Not Found" Errors
+
+**Symptom:**
+- Batch file shows errors during execution
+- References to "NUL" in error messages
+
+**Cause:** Old batch file version (pre-DOS 6.22 compatibility fix)
+
+**Solution:**
+1. Ask engineering to verify latest files deployed
+2. Force update:
+ ```
+ DEL C:\BAT\*.BAT
+ C:\NET\STARTNET
+ T:\COMMON\ProdSW\DEPLOY.BAT TS-XX
+ ```
+3. Reboot
+
+---
+
+### Machine Name Not Set
+
+**Symptom:**
+- CTONW shows: "[ERROR] MACHINE variable not set"
+- ECHO %MACHINE% shows nothing
+
+**Cause:** Deployment never completed or AUTOEXEC.BAT corrupted
+
+**Solution:**
+Run deployment again:
+```
+T:\UPDATE.BAT TS-04
+```
+
+**This re-installs AUTOEXEC.BAT with correct machine name.**
+
+---
+
+### Disk Full
+
+**Symptom:**
+- Error: "Insufficient disk space"
+- DIR C:\ shows 0 bytes free
+
+**Causes:**
+- .BAK backup files accumulating
+- Test data files in C:\ATE
+- Log files growing
+
+**Solution:**
+
+#### Clean Backup Files:
+```
+DEL C:\BAT\*.BAK
+```
+
+#### Clean Test Data:
+```
+DEL C:\ATE\8BDATA\*.DAT
+DEL C:\ATE\DSCDATA\*.DAT
+DEL C:\ATE\HVDATA\*.DAT
+```
+(After uploading to network!)
+
+#### Check Disk Space:
+```
+DIR C:\
+```
+
+Should show several MB free.
+
+---
+
+### Test Data Not Uploading
+
+**Symptom:**
+- CTONW completes but data not in database
+- Engineers report missing test data
+
+**Check Upload Location:**
+
+Data goes to: `T:\TS-XX\LOGS\` (not T:\TS-XX\ProdSW\)
+
+**Verify manually:**
+```
+DIR T:\TS-04\LOGS\8BLOG\
+```
+
+Should show your .DAT files.
+
+**If empty:**
+- Check source: `DIR C:\ATE\8BDATA\*.DAT`
+- If source empty, no data to upload
+- If source has data, run `C:\BAT\CTONW` again
+
+---
+
+## FAQ
+
+### Q: Do I need to run any commands after booting?
+
+**A:** No! The system handles everything automatically. Just wait for "System Ready" and start testing.
+
+---
+
+### Q: How do I know if updates downloaded?
+
+**A:** Watch the boot screen. You'll see:
+```
+[1/4] Updating batch files from T:\COMMON\ProdSW...
+ [OK] Batch files updated from COMMON
+```
+
+Or run: `C:\BAT\CHECKUPD` to see available updates.
+
+---
+
+### Q: Can I turn off automatic updates?
+
+**A:** Not recommended. Automatic updates ensure you always have the latest software.
+
+If you must disable temporarily (for troubleshooting), see [Boot Takes Too Long - Step 3](#boot-takes-too-long).
+
+---
+
+### Q: What if I make a mistake during testing?
+
+**A:** Reboot the machine. NWTOC will restore original files from network.
+
+Or manually restore from backup:
+```
+COPY C:\BAT\FILENAME.BAK C:\BAT\FILENAME.BAT
+```
+
+---
+
+### Q: How do I get help?
+
+**A:**
+1. Check this guide first
+2. Ask test lead
+3. Contact engineering
+4. Email IT support
+
+**For emergencies:** Call IT hotline
+
+---
+
+### Q: Can I modify batch files on the DOS machine?
+
+**A:** You can, but changes will be lost on next reboot (NWTOC overwrites).
+
+**To make permanent changes:**
+1. Tell engineering what you need
+2. They update file on AD2
+3. File syncs to NAS
+4. Next reboot downloads new version
+
+---
+
+### Q: What's the difference between UPDATE.BAT locations?
+
+**A:**
+
+**T:\UPDATE.BAT** - Initial deployment command
+- Usage: `T:\UPDATE.BAT TS-04`
+- Run once per machine (first time setup)
+
+**C:\BAT\UPDATE.BAT** - Full backup command
+- Usage: `C:\BAT\UPDATE`
+- Run before major changes
+
+Same name, different purposes!
+
+---
+
+### Q: Why does boot take longer than before?
+
+**A:** Automatic updates add 30-60 seconds to boot time.
+
+**Before:** ~60 seconds (just network start)
+**Now:** ~150 seconds (network + updates + upload)
+
+**Trade-off:** Slower boot, but no manual commands needed.
+
+Net result: Faster testing start (no waiting for you to run commands).
+
+---
+
+### Q: What are .BAK files in C:\BAT?
+
+**A:** Backup files created by NWTOC before overwriting.
+
+**Safe to delete:** Yes (after verifying updates work)
+
+**Useful for:** Rollback to previous version if needed
+
+**Cleanup:**
+```
+DEL C:\BAT\*.BAK
+```
+
+---
+
+### Q: Do I need to deploy every machine individually?
+
+**A:** Yes, but only once per machine.
+
+**After initial deployment:** All machines update automatically on reboot.
+
+**Deployment checklist:**
+- [ ] TS-01 deployed
+- [ ] TS-02 deployed
+- ...
+- [ ] TS-30 deployed
+

+
+## File-by-File Changes
+
+### 1. AUTOEXEC.BAT (Complete Rewrite)
+
+**Previous Version:** 103 lines, verbose annotations, manual workflow
+**New Version:** 82 lines, automatic workflow
+
+#### Changes Made:
+1. **Removed verbose REM annotations**
+ - Old: Multi-line header blocks explaining every step
+ - New: Concise, single-line functional descriptions
+
+2. **Fixed DOS 6.22 compatibility issues**
+ - Changed: `IF NOT EXIST C:\TEMP\NUL` → `IF NOT EXIST C:\TEMP\*.*`
+ - Changed: `IF NOT EXIST C:\BATCH\NUL` → `IF NOT EXIST C:\BATCH\*.*`
+ - Changed: `IF NOT EXIST T:\NUL` → `IF NOT EXIST T:\*.*`
+ - Reason: NUL is a reserved device name in DOS, cannot be used for directory tests
+
+3. **Added automatic update system** (Lines 49-55)
+ ```batch
+ REM Download latest software updates from network
+ ECHO Checking for software updates...
+ IF EXIST C:\BAT\NWTOC.BAT CALL C:\BAT\NWTOC.BAT
+
+ REM Upload test data to network for database import
+ ECHO Uploading test data to network...
+ IF EXIST C:\BAT\CTONW.BAT CALL C:\BAT\CTONW.BAT
+ ```
+ - Previously: Users had to manually run NWTOC and CTONW
+ - Now: Runs automatically after network start on every boot
+
+4. **Removed manual command listing**
+ - Old: Displayed list of available commands (UPDATE, CHECKUPD, etc.)
+ - New: System is fully automatic, no manual intervention needed
+
+#### Impact:
+- **User Experience:** No manual steps required after reboot
+- **Maintenance:** 21% reduction in file size
+- **Reliability:** Guaranteed update execution on every boot
+
+---
+
+### 2. NWTOC.BAT (Complete Rewrite)
+
+**Previous Version:** Various NUL references, verbose annotations
+**New Version:** 221 lines, DOS 6.22 compliant
+
+#### Changes Made:
+1. **Fixed 9 NUL device references**
+ - Line 50: `T:\COMMON\NUL` → `T:\COMMON\*.*`
+ - Line 51: `T:\COMMON\ProdSW\NUL` → `T:\COMMON\ProdSW\*.*`
+ - Line 54: `T:\%MACHINE%\NUL` → `T:\%MACHINE%\*.*`
+ - Line 55: `T:\%MACHINE%\ProdSW\NUL` → `T:\%MACHINE%\ProdSW\*.*`
+ - Line 80: `C:\BAT\NUL` → `C:\BAT\*.*`
+ - Lines 100, 103, 104: Machine-specific directory checks
+ - Line 131: `T:\COMMON\DOS\NUL` → `T:\COMMON\DOS\*.*`
+ - Line 170: `T:\COMMON\NET\NUL` → `T:\COMMON\NET\*.*`
+
+2. **Rewrote all REM annotations**
+ - Removed verbose multi-line explanations
+ - Added concise functional descriptions
+ - Improved readability without changing logic
+
+3. **No functional logic changes**
+ - Still downloads from T:\COMMON\ProdSW to C:\BAT
+ - Still downloads from T:\%MACHINE%\ProdSW to C:\BAT and C:\ATE
+ - Still handles system file staging (AUTOEXEC.NEW, CONFIG.NEW)
+ - Still updates network client files
+
+#### Impact:
+- **Compatibility:** 100% DOS 6.22 compatible
+- **Reliability:** No more "Invalid path" errors from NUL references
+- **Maintainability:** Clearer annotations, easier to understand
+
+---
+
+### 3. CTONW.BAT (Complete Rewrite)
+
+**Previous Version:** Various NUL references, unclear data routing
+**New Version:** 272 lines, clarified test data flow
+
+#### Changes Made:
+1. **Fixed 14 NUL device references**
+ - Line 97: `C:\BAT\NUL` → `C:\BAT\*.*`
+ - Line 109: `T:\%MACHINE%\NUL` → `T:\%MACHINE%\*.*`
+ - Line 112: `%TARGETDIR%\NUL` → `%TARGETDIR%\*.*`
+ - Line 115: `%TARGETDIR%\NUL` → `%TARGETDIR%\*.*`
+ - Line 121: `%LOGSDIR%\NUL` → `%LOGSDIR%\*.*`
+ - Lines 177-182: All log subdirectories (8BLOG, DSCLOG, HVLOG, PWRLOG, RMSLOG, 7BLOG)
+ - Lines 188-203: All data source directories (8BDATA, DSCDATA, etc.)
+
+2. **Clarified test data routing**
+ - Programs/Config: C:\ATE → T:\%MACHINE%\ProdSW
+ - Test Data (.DAT): C:\ATE\*DATA → T:\%MACHINE%\LOGS\*LOG
+ - Reason: LOGS folder is for database import, ProdSW is for software distribution
+
+3. **Added COMMON upload confirmation**
+ - Warns user when uploading to COMMON (affects all machines)
+ - Uses CHOICE command for Y/N confirmation
+ - Prevents accidental global deployment
+
+#### Impact:
+- **Data Flow:** Clear separation between programs and test data
+- **Safety:** Confirmation required for COMMON uploads
+- **Compatibility:** All NUL references fixed
+
+---
+
+### 4. DEPLOY.BAT (Major Simplification)
+
+**Previous Version:** 391 lines, complex logic, network verification
+**New Version:** 188 lines, template-based approach
+
+#### Changes Made:
+1. **Removed network drive verification**
+ - Old: Checked if T: drive accessible before proceeding
+ - New: No T: drive check (script runs from T: drive)
+ - Reason: If script is running, network is already accessible
+
+2. **Simplified AUTOEXEC.BAT installation**
+ - Old: Backed up existing AUTOEXEC, parsed for SET MACHINE, complex merging
+ - New: Copy template from network, replace machine name, done
+ - Reason: All machines use identical AUTOEXEC.BAT
+
+3. **Fixed execution order**
+ - Old: Modified AUTOEXEC.BAT FIRST, copied batch files SECOND
+ - New: Copy batch files FIRST, modify AUTOEXEC.BAT SECOND
+ - Reason: Prevents race condition where AUTOEXEC calls files that don't exist yet
+
+4. **Fixed DOS 6.22 multi-pipe issue**
+ - Old: `TYPE file | FIND | FIND | FIND >> output` (line 92)
+ - New: Multiple temp files with single pipes
+ ```batch
+ TYPE C:\AUTOEXEC.TM1 | FIND /V "REM Dataforth" > C:\AUTOEXEC.TM2
+ TYPE C:\AUTOEXEC.TM2 | FIND /V "REM Automatically" > C:\AUTOEXEC.TM3
+ TYPE C:\AUTOEXEC.TM3 | FIND /V "REM Version:" > C:\AUTOEXEC.TM4
+ TYPE C:\AUTOEXEC.TM4 | FIND /V "REM Last modified" > C:\AUTOEXEC.TM5
+ TYPE C:\AUTOEXEC.TM5 | FIND /V "REM Set machine identity" >> C:\AUTOEXEC.BAT
+ ```
+ - Reason: Multi-pipe with redirect is unreliable in DOS 6.22
+
+5. **Reduced complexity by 52%**
+ - 391 lines → 188 lines
+ - Removed 203 lines of unnecessary code
+ - Improved readability and maintainability
+
+#### Impact:
+- **Deployment Time:** Faster execution (fewer operations)
+- **Reliability:** No race conditions, proper execution order
+- **Maintainability:** Much easier to understand and modify
+
+---
+
+### 5. UPDATE.BAT (New Root Redirect)
+
+**Previous Version:** N/A (different purpose)
+**New Version:** 5 lines, simple redirect
+
+#### Changes Made:
+1. **Created new UPDATE.BAT in test root**
+ ```batch
+ @ECHO OFF
+ REM UPDATE.BAT - Redirect to DEPLOY.BAT in proper location
+ REM Usage: UPDATE.BAT machine-name
+ REM Example: UPDATE.BAT TS-4R
+ CALL T:\COMMON\ProdSW\DEPLOY.BAT %1
+ ```
+
+2. **Deleted old DEPLOY.BAT from root**
+ - Removed duplicate DEPLOY.BAT from T:\ root
+ - Only one DEPLOY.BAT now exists: T:\COMMON\ProdSW\DEPLOY.BAT
+
+#### Impact:
+- **User Experience:** Shorter command path (T:\UPDATE.BAT vs T:\COMMON\ProdSW\DEPLOY.BAT)
+- **Backward Compatibility:** Works with existing workflows
+- **Maintenance:** No duplicate files to update
+
+---
+
+## Compatibility Verification
+
+All files have been verified with automated DOS 6.22 compatibility checker.
+
+### Issues Fixed:
+- [OK] 24 NUL device references → Changed to `*.*` wildcard
+- [OK] Multi-pipe with redirect → Broke into temp file steps
+- [OK] All false positives confirmed (word "start" in REM comments)
+
+### Final Status:
+```
+AUTOEXEC.BAT: [OK] No incompatibilities found
+NWTOC.BAT: [OK] No incompatibilities found
+CTONW.BAT: [OK] No incompatibilities found (CHOICE.COM available in DOS 6.22)
+DEPLOY.BAT: [OK] No incompatibilities found
+UPDATE.BAT: [OK] No incompatibilities found
+```
+
+---
+

+## Workflow Changes
+
+### Old Workflow (Manual):
+1. DOS machine boots
+2. Network starts
+3. User manually runs: `C:\BAT\NWTOC`
+4. User manually runs: `C:\BAT\CTONW`
+5. Testing can begin
+
+**Total User Actions:** 2 manual commands required
+
+### New Workflow (Automatic):

+3. NWTOC runs automatically (downloads updates)
+4. CTONW runs automatically (uploads test data)
+5. Testing can begin
+
+**Total User Actions:** 0 manual commands required
+
+---
+
+## Backward Compatibility
+
+### Breaking Changes:
+- **None** - All existing workflows continue to function
+
+### New Features:
+- Automatic updates on boot
+- Simplified deployment command
+
+### Deprecated Features:
+- Manual NWTOC/CTONW execution (still works, but unnecessary)
+- ARCHBAT.BAT (no longer needed, can be removed)
+
+---
+
+## Performance Impact
+
+### Boot Time:
+- **Increase:** ~30-60 seconds (NWTOC + CTONW execution)
+- **Benefit:** No manual intervention required
+- **Net Effect:** Faster overall testing start time
+
+### Network Traffic:
+- **No change:** Same files transferred as manual workflow
+- **Timing:** Transfers occur during boot instead of manually
+
+### Disk Usage:
+- **No change:** Same files stored as before
+- **Cleanup:** Backup files (.BAK) created during updates
+
+---
+

+
+## Quick Start
+
+**Need to deploy a software update quickly? Follow these steps:**
+
+1. Map network drive to `\\AD2\test` (if not already mapped)
+2. Copy batch files to: `\\AD2\test\COMMON\ProdSW\`
+3. Wait 15 minutes for automatic sync to NAS
+4. DOS machines will download updates on next reboot
+
+**That's it!** No manual commands needed on DOS machines.
+
+---
+
+## Accessing the Test Share
+
+Engineers have share-level access to AD2's test folder via SMB.
+
+### Option 1: Map Network Drive (Recommended)
+
+**Windows File Explorer:**
+
+1. Open File Explorer
+2. Click "This PC" in left sidebar
+3. Click "Map network drive" button (or right-click → "Map network drive")
+4. Choose drive letter: `T:` (recommended for consistency)
+5. Enter path: `\\AD2\test`
+6. Check "Reconnect at sign-in" (optional)
+7. Click "Finish"
+8. Enter credentials if prompted:
+ - Username: `INTRANET\[your-username]`
+ - Password: [your-password]
+
+**Command Line (cmd.exe):**
+
+```cmd
+net use T: \\AD2\test /persistent:yes
+```
+
+**PowerShell:**
+
+```powershell
+New-PSDrive -Name "T" -PSProvider FileSystem -Root "\\AD2\test" -Persist
+```
+
+![Screenshot: Map Network Drive Dialog]
+*Screenshot placeholder: Windows "Map network drive" dialog showing \\AD2\test path*
+
+---
+
+### Option 2: Direct UNC Path
+
+If you don't want to map a drive, use the UNC path directly:
+
+**Windows File Explorer:**
+- Navigate to: `\\AD2\test\COMMON\ProdSW\`
+- Drag and drop files directly
+
+**Command Line:**
+```cmd
+copy C:\MyFiles\*.BAT \\AD2\test\COMMON\ProdSW\
+```
+
+**PowerShell:**
+```powershell
+Copy-Item C:\MyFiles\*.BAT -Destination \\AD2\test\COMMON\ProdSW\
+```
+
+---
+
+### Verifying Access
+
+**Check if you have access:**
+
+1. Open File Explorer
+2. Navigate to: `\\AD2\test\`
+3. You should see folders: COMMON, TS-01, TS-02, ..., TS-30
+
+**Expected folder structure:**
+```
+\\AD2\test\
+├── COMMON\
+│ ├── ProdSW\ ← Place batch files here
+│ ├── DOS\ ← System files (AUTOEXEC.NEW, CONFIG.NEW)
+│ └── NET\ ← Network client updates
+├── TS-01\ ← Machine-specific folders
+├── TS-02\
+├── ...
+└── TS-30\
+```
+
+![Screenshot: Test Share Folder Structure]
+*Screenshot placeholder: Windows Explorer showing \\AD2\test\ folder structure with COMMON and TS-XX folders*
+

+
+## File Placement Guide
+
+### Where to Place Files
+
+| File Type | Destination | Scope | Auto-Deployed To |
+|-----------|-------------|-------|------------------|
+| Batch files (.BAT) | `\\AD2\test\COMMON\ProdSW\` | All machines | C:\BAT\ on all DOS machines |
+| Executables (.EXE) | `\\AD2\test\COMMON\ProdSW\` | All machines | C:\ATE\ on all DOS machines |
+| Config files (.CFG) | `\\AD2\test\COMMON\ProdSW\` | All machines | C:\ATE\ on all DOS machines |
+| System files (AUTOEXEC.NEW) | `\\AD2\test\COMMON\DOS\` | All machines | Staged for reboot |
+| Network client files | `\\AD2\test\COMMON\NET\` | All machines | C:\NET\ on all DOS machines |
+| Machine-specific files | `\\AD2\test\TS-XX\ProdSW\` | Single machine | C:\BAT\ and C:\ATE\ on specific machine |
+
+---
+
+### Step-by-Step: Deploy Batch File Update
+
+**Scenario:** You've updated CHECKUPD.BAT and need to deploy it to all machines.
+
+**Steps:**
+
+1. **Access the share:**
+ ```cmd
+ \\AD2\test\COMMON\ProdSW\
+ ```
+
+2. **Backup existing file (optional but recommended):**
+ - Rename `CHECKUPD.BAT` to `CHECKUPD.BAK`
+ - Or copy to `_backup\` folder
+
+3. **Copy new file:**
+ - Drag your updated `CHECKUPD.BAT` to `\\AD2\test\COMMON\ProdSW\`
+ - Overwrite when prompted
+
+4. **Verify copy:**
+ - Check file size and timestamp match your source file
+ - Open file to verify contents (right-click → Edit)
+
+5. **Wait for sync:**
+ - AD2 syncs to NAS every 15 minutes
+ - After 15 minutes, file is available at `T:\COMMON\ProdSW\` on DOS machines
+
+6. **Verify on DOS machine:**
+ - Next reboot: NWTOC downloads new file to C:\BAT\
+ - Or manually run: `T:\COMMON\ProdSW\NWTOC.BAT` on DOS machine
+
+![Screenshot: File Copy Operation]
+*Screenshot placeholder: Windows Explorer copying CHECKUPD.BAT to \\AD2\test\COMMON\ProdSW\*
+
+---
+
+### Step-by-Step: Deploy Machine-Specific Update
+
+**Scenario:** TS-04 needs a special configuration file.
+
+**Steps:**
+
+1. **Identify target machine folder:**
+ ```cmd
+ \\AD2\test\TS-04\ProdSW\
+ ```
+
+2. **Create folder if it doesn't exist:**
+ - Right-click in `\\AD2\test\TS-04\`
+ - Select "New" → "Folder"
+ - Name it: `ProdSW`
+
+3. **Copy machine-specific file:**
+ - Drag your file to `\\AD2\test\TS-04\ProdSW\`
+
+4. **Wait for sync (15 minutes)**
+
+5. **On TS-04 DOS machine:**
+ - Reboot machine
+ - NWTOC automatically downloads from `T:\TS-04\ProdSW\` to C:\BAT\ and C:\ATE\
+
+**Important:** Machine-specific files take precedence over COMMON files.
+
+---
+
+## Sync Process Explained
+
+### How Sync Works
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│ Step 1: Engineer places file on AD2 │

+ │
+ ▼
+┌─────────────────────────────────────────────────────────────────┐

+│ Step 5: File now deployed on DOS machine │
+│ Location: C:\BAT\NEWFILE.BAT │
+│ Status: Ready to use │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+---
+
+### Sync Timing
+
+| Action | Time Required | Notes |
+|--------|---------------|-------|
+| File copy to AD2 | Instant | Limited by network speed |
+| AD2 → NAS sync | 0-15 minutes | Depends on scheduled task timing |
+| NAS → DOS machine | Next reboot | Or manual NWTOC execution |
+| **Total deployment time** | **15 min - 24 hours** | Depends on reboot schedule |
+
+**Pro Tip:** For urgent updates, ask test staff to reboot specific machines or manually run NWTOC.
+
+---
+
+### Verifying Sync Status
+
+**Check if file reached NAS:**
+
+1. **Via DOS machine:**
+ - Log into any DOS machine
+ - Type: `DIR T:\COMMON\ProdSW\YOURFILE.BAT`
+ - If listed, sync complete
+
+2. **Via SSH (if you have access):**
+ ```bash
+ ssh admin@192.168.0.9
+ ls -lh /data/test/COMMON/ProdSW/
+ ```
+
+3. **Via test staff:**
+ - Ask them to check T: drive on DOS machine
+ - Faster than waiting 15 minutes
+
+---
+
+## Update Workflow
+
+### Normal Update Process (Automatic)
+
+**For Test Staff - No manual steps required:**
+
+1. Engineer places file on AD2
+2. File syncs to NAS (15 minutes)
+3. DOS machine reboots
+4. AUTOEXEC.BAT runs automatically:
+ - Network starts
+ - NWTOC downloads updates from T:\COMMON\ProdSW
+ - NWTOC downloads machine-specific updates from T:\TS-XX\ProdSW
+ - CTONW uploads test data to T:\TS-XX\LOGS
+5. System ready for testing
+
+**No intervention required from test staff.**
+
+---
+
+### Expedited Update Process (Manual)
+
+**For urgent updates that can't wait for reboot:**
+
+1. Engineer places file on AD2
+2. Wait 15 minutes for sync to NAS
+3. Ask test staff to run on DOS machine:
+ ```
+ C:\BAT\NWTOC.BAT
+ ```
+4. Updates downloaded immediately
+5. No reboot required
+
+---
+
+### System File Updates (AUTOEXEC.BAT, CONFIG.SYS)
+
+**These require reboot and special handling:**
+
+1. **Create staged files:**
+ - Rename to: `AUTOEXEC.NEW` or `CONFIG.NEW`
+ - Place in: `\\AD2\test\COMMON\DOS\`
+
+2. **Wait for sync (15 minutes)**
+
+3. **On DOS machine reboot:**
+ - NWTOC detects .NEW files
+ - Calls STAGE.BAT automatically
+ - Creates REBOOT.BAT
+ - Displays message: "Reboot required"
+
+4. **Test staff runs:**
+ ```
+ C:\BAT\REBOOT.BAT
+ ```
+ - System reboots
+ - REBOOT.BAT applies staged files
+ - New AUTOEXEC.BAT/CONFIG.SYS active after reboot
+
+**Warning:** System file updates require careful testing. Always test on one machine first.
+
+---
+
+## Troubleshooting Guide
+
+### Issue 1: Cannot Access \\AD2\test\
+
+**Symptom:**

+
+### Issue 2: File Copied but DOS Machine Not Updated
+
+**Symptom:**
+- File placed on \\AD2\test\COMMON\ProdSW\
+- DOS machine still has old version after reboot
+
+**Troubleshooting Steps:**
+
+#### Step 1: Verify File on AD2
+```cmd
+dir \\AD2\test\COMMON\ProdSW\YOURFILE.BAT
+```
+- Check file size and timestamp
+- Verify it matches your source file
+
+#### Step 2: Wait for Sync (15 minutes)
+- Sync runs every 15 minutes
+- Check clock - has 15 minutes elapsed since you copied?
+
+#### Step 3: Verify File on NAS (via DOS)
+On DOS machine:
+```
+DIR T:\COMMON\ProdSW\YOURFILE.BAT
+```
+- If missing: Sync hasn't completed or sync process failed
+- If present: Continue to Step 4
+
+#### Step 4: Check DOS Machine Date/Time
+NWTOC uses `/D` flag (only copy if newer):
+```
+XCOPY T:\COMMON\ProdSW\*.bat C:\BAT\ /D /Y
+```
+
+On DOS machine:
+```
+DATE
+TIME
+```
+- If DOS clock is in the future, XCOPY won't copy "older" files
+- **Solution:** Set correct date/time on DOS machine
+
+#### Step 5: Force Update
+On DOS machine, bypass date check:
+```
+DEL C:\BAT\YOURFILE.BAT
+C:\BAT\NWTOC.BAT
+```
+- This forces re-download
+
+#### Step 6: Check NWTOC Error Messages
+Run NWTOC manually and watch for errors:
+```
+C:\BAT\NWTOC.BAT
+```
+Look for:
+- `[ERROR] T: drive not available`
+- `[ERROR] Update initialization failed`
+- `[ERROR] Update terminated by user`
+
+---
+
+### Issue 3: Sync Not Happening (15+ Minutes Elapsed)
+
+**Symptom:**
+- File on AD2, but not appearing on NAS after 15+ minutes
+- `DIR T:\COMMON\ProdSW\` on DOS shows old file
+
+**Troubleshooting Steps:**
+
+#### Step 1: Verify Scheduled Task on AD2
+**If you have SSH access to AD2:**
+```powershell
+ssh INTRANET\sysadmin@192.168.0.6
+Get-ScheduledTask | Where-Object {$_.TaskName -like "*sync*"}
+```
+- Look for task that syncs to NAS
+- Check: State = "Ready", LastRunTime recent
+
+**If task not running:**
+```powershell
+Start-ScheduledTask -TaskName "SyncToNAS"
+```
+
+#### Step 2: Check NAS Accessibility from AD2
+**If you have SSH access to AD2:**
+```cmd
+ping 192.168.0.9
+net use \\192.168.0.9\test
+```
+- If ping fails: NAS is down or network issue
+- If net use fails: SMB1 issue or credentials
+
+#### Step 3: Manually Trigger Sync
+**Contact IT to manually run sync script on AD2**
+
+#### Step 4: Verify NAS is Online
+```cmd
+ping 192.168.0.9
+```
+- If no response: NAS is down, contact IT
+
+---
+
+### Issue 4: "Invalid Path" Error on DOS Machine
+
+**Symptom:**
+- DOS displays: "Invalid path" or "File not found"
+- NWTOC or CTONW fails with path errors
+
+**Possible Causes:**
+
+#### Cause 1: Using NUL Device Name
+**Old code (incorrect):**
+```batch
+IF NOT EXIST C:\BAT\NUL MD C:\BAT
+```
+
+**New code (correct):**
+```batch
+IF NOT EXIST C:\BAT\*.* MD C:\BAT
+```
+
+**Solution:**
+- Verify batch files are latest version (with DOS 6.22 compatibility fixes)
+- Replace old batch files with new versions
+- Check file timestamp: Should be 2026-01-19 or later
+
+#### Cause 2: Long File Paths
+DOS 6.22 has 128-character path limit:
+**Solution:**
+- Use shorter path names
+- Avoid deeply nested directories
+
+#### Cause 3: Special Characters in Filenames
+DOS doesn't support: `| < > / \ : " * ?`
+**Solution:**
+- Rename files to use only: A-Z, 0-9, dash, underscore
+- Follow 8.3 naming convention
+
+---
+
+### Issue 5: DEPLOY.BAT Fails on DOS Machine
+
+**Symptom:**
+- Running: `T:\UPDATE.BAT TS-XX` fails
+- Error messages during deployment
+
+**Troubleshooting Steps:**
+
+#### Step 1: Verify Machine Name Argument
+```
+T:\UPDATE.BAT TS-04
+```
+- Machine name must be provided
+- Must match network folder: T:\TS-04\
+
+#### Step 2: Verify DEPLOY.BAT Exists
+```
+DIR T:\COMMON\ProdSW\DEPLOY.BAT
+```
+- If missing, files not synced yet
+
+#### Step 3: Verify Template AUTOEXEC.BAT Exists
+```
+DIR T:\COMMON\ProdSW\AUTOEXEC.BAT
+```
+- DEPLOY copies this as template
+- If missing, deployment will fail
+
+#### Step 4: Check C: Drive Space
+```
+DIR C:\
+```
+- DEPLOY creates C:\BAT\ and copies files
+- Requires ~500 KB free space minimum
+
+#### Step 5: Run with Output Visible
+```
+T:\COMMON\ProdSW\DEPLOY.BAT TS-04
+```
+- Watch each step
+- Note exactly where it fails
+- Check error messages
+
+**Common Errors:**
+- `[ERROR] Machine name not provided` → Missing argument
+- `[ERROR] Could not create C:\BAT directory` → Disk full or permissions
+- `[ERROR] Failed to copy files from network` → T: drive issue
+- `[ERROR] Could not copy AUTOEXEC.BAT template` → Template missing
+
+---
+
+### Issue 6: System Files Not Updating (AUTOEXEC.BAT)
+
+**Symptom:**
+- Placed AUTOEXEC.NEW in \\AD2\test\COMMON\DOS\
+- DOS machine not showing staged update
+
+**Troubleshooting Steps:**
+
+#### Step 1: Verify File Placement
+Correct location:
+```
+\\AD2\test\COMMON\DOS\AUTOEXEC.NEW
+```
+**Not:**
+```
+\\AD2\test\COMMON\ProdSW\AUTOEXEC.NEW (wrong!)
+```
+
+#### Step 2: Verify File Extension
+Must be `.NEW`:
+```
+AUTOEXEC.NEW (correct)
+AUTOEXEC.BAT (wrong - will be ignored)
+```
+
+#### Step 3: Wait for Sync + Reboot
+- File must sync to NAS (15 minutes)
+- DOS machine must reboot
+- NWTOC runs and detects .NEW file
+
+#### Step 4: Check for STAGE.BAT
+On DOS machine:
+```
+DIR C:\BAT\STAGE.BAT
+```
+- If missing, NWTOC cannot stage updates
+- **Solution:** Deploy STAGE.BAT to COMMON\ProdSW first
+
+#### Step 5: Check for Staged Files
+After reboot, on DOS machine:
+```
+DIR C:\AUTOEXEC.NEW
+DIR C:\CONFIG.NEW
+```
+- If present: Staging worked, need to run REBOOT.BAT
+- If missing: NWTOC didn't detect or staging failed
+
+#### Step 6: Manual Staging
+If automatic staging failed:
+```
+COPY T:\COMMON\DOS\AUTOEXEC.NEW C:\AUTOEXEC.NEW
+C:\BAT\STAGE.BAT
+```
+
+---
+
+### Issue 7: CTONW Upload Fails
+
+**Symptom:**
+- Test staff reports CTONW errors
+- Test data not reaching T:\TS-XX\LOGS
+
+**Troubleshooting Steps:**
+
+#### Step 1: Verify MACHINE Variable
+On DOS machine:
+```
+ECHO %MACHINE%
+```
+- Should show: `TS-04` (or correct machine name)
+- If blank: AUTOEXEC.BAT SET MACHINE not set
+- **Solution:** Run DEPLOY.BAT again
+
+#### Step 2: Verify Target Folder Exists
+On DOS machine:
+```
+DIR T:\TS-04\
+```
+- If missing: CTONW will create it
+- If "Access denied": Permission issue on NAS
+
+#### Step 3: Check Source Data
+On DOS machine:
+```
+DIR C:\ATE\8BDATA\*.DAT
+```
+- If no .DAT files, nothing to upload
+- CTONW only uploads .DAT files to LOGS
+
+#### Step 4: Run CTONW with Visible Output
+```
+C:\BAT\CTONW.BAT
+```
+- Watch for error messages
+- Check which step fails
+
+**Common Errors:**
+- `[ERROR] MACHINE variable not set` → Run DEPLOY.BAT
+- `[ERROR] T: drive not available` → Network down
+- `[ERROR] Could not create target directory` → NAS permission issue
+- `[ERROR] Upload initialization failed` → Memory or path issue
+
+---
+
+### Issue 8: Network Drive (T:) Not Mapped
+
+**Symptom:**
+- DOS machine shows: `[ERROR] T: drive not available`
+- Cannot access T:\
+
+**Troubleshooting Steps:**
+
+#### Step 1: Check Network Stack
+On DOS machine:
+```
+NET
+```
+- Should show Microsoft Network Client loaded
+- If "Bad command or file name": Network not started
+
+#### Step 2: Restart Network Client
+```
+C:\NET\STARTNET.BAT
+```
+- Watch for error messages
+- Should map T: and X: drives
+
+#### Step 3: Verify T: Drive After Network Start
+```
+DIR T:\
+```
+- Should show COMMON, TS-XX folders
+- If error: Network mapping failed
+
+#### Step 4: Check NAS Accessibility
+```
+PING 192.168.0.9
+```
+- DOS 6.22 may not have ping
+- Try: `DIR T:\` instead
+
+#### Step 5: Check STARTNET.BAT Configuration
+```
+EDIT C:\NET\STARTNET.BAT
+```
+Look for:
+```batch
+NET USE T: \\D2TESTNAS\test
+```
+- Verify server name and share correct
+- Verify drive letter is T:
+
+---
+
+### Issue 9: Backup Files Accumulating (.BAK files)
+
+**Symptom:**
+- C:\BAT\ filling up with .BAK files
+- Running out of disk space on DOS machines
+
+**Explanation:**
+- NWTOC creates .BAK backups before overwriting files
+- This is intentional for rollback capability
+
+**Solution:**
+
+#### Option 1: Periodic Cleanup (Recommended)
+On DOS machine:
+```
+DEL C:\BAT\*.BAK
+```
+- Safe to delete after verifying updates work
+- Keep most recent .BAK for rollback
+
+#### Option 2: Automated Cleanup
+Add to AUTOEXEC.BAT (after NWTOC call):
+```batch
+REM Clean up backup files older than current
+FOR %%F IN (C:\BAT\*.BAK) DO DEL %%F >NUL 2>NUL
+```
+
+#### Option 3: Keep Recent Backups Only
+```batch
+REM Keep only today's backups, delete older
+DEL C:\BAT\OLDFILE1.BAK
+DEL C:\BAT\OLDFILE2.BAK
+```
+
+---
+
+### Issue 10: Updates Work but Performance Slow
+
+**Symptom:**
+- Updates download successfully
+- Boot process takes 5+ minutes
+- Network transfers slow
+
+**Possible Causes:**
+
+#### Cause 1: Network Congestion
+- Multiple DOS machines booting simultaneously
+- All downloading from NAS at once
+
+**Solution:**
+- Stagger reboot times
+- Reboot in batches (5 machines at a time)
+
+#### Cause 2: NAS Under Load
+- Check NAS performance
+- Verify NAS not running other intensive tasks
+
+**Solution:**
+- Schedule updates during off-hours
+- Reduce concurrent connections
+
+#### Cause 3: Large File Transfers
+- Check file sizes in ProdSW
+- Remove unnecessary large files
+
+**Solution:**
+- Keep ProdSW lean (< 10 MB total)
+- Move large files to separate share
+
+---
+
+## Best Practices
+
+### File Naming Conventions
+
+**DO:**
+- Use uppercase: `MYFILE.BAT`
+- Follow 8.3 naming: `FILENAME.EXT` (8 chars + 3 char extension)
+- Use underscores: `MY_FILE.BAT`
+- Use dates: `BACKUP_20260119.BAT`
+
+**DON'T:**
+- Use spaces: `MY FILE.BAT` (will cause issues)
+- Use special characters: `FILE@#$.BAT`
+- Exceed 8 characters: `VERYLONGFILENAME.BAT` (truncated to `VERYLONG.BAT`)
+- Use lowercase (DOS is case-insensitive, but uppercase is convention)
+
+---
+
+### Testing Updates
+
+**Always test on one machine first:**
+
+1. **Choose test machine:** TS-30 (designated test machine)
+2. **Deploy to TS-30 folder first:**
+ ```
+ \\AD2\test\TS-30\ProdSW\NEWFILE.BAT
+ ```
+3. **Wait for sync + reboot TS-30**
+4. **Verify functionality on TS-30**
+5. **If successful, deploy to COMMON:**
+ ```
+ \\AD2\test\COMMON\ProdSW\NEWFILE.BAT
+ ```
+
+**This prevents breaking all 30 machines with one bad update.**
+
+---
+
+### Backup Strategy
+
+**Before deploying updates:**
+
+1. **Copy old file to backup folder:**
+ ```
+ \\AD2\test\COMMON\ProdSW\_backup\OLDFILE_20260119.BAK
+ ```
+
+2. **Create dated backup:**
+ - Include date in filename
+ - Keep backups for 30 days
+ - Delete older backups monthly
+
+3. **Document changes:**
+ - Add entry to CHANGELOG.txt in ProdSW folder
+ - Include: Date, File, Version, Changes, Your Name
+
+---
+
+### Communication
+
+**Notify test staff before updates:**
+
+1. **Email test team:**
+ - Subject: "DOS Update: [File] - [Date]"
+ - Include: What changed, Expected behavior, Reboot required?
+
+2. **For urgent updates:**
+ - Phone call or Teams message
+ - Ask them to reboot specific machines
+ - Verify update successful
+
+3. **For system file updates:**
+ - **Always notify test lead**
+ - Schedule during low-activity time
+ - Be available for troubleshooting
+
+---
+
+### Version Control
+
+**Track versions in filenames or comments:**
+
+**Option 1: Version in Filename**
+```
+\\AD2\test\COMMON\ProdSW\_versions\CHECKUPD_v1.2.BAT
+```
+
+**Option 2: Version in File Header**
+```batch
+@ECHO OFF
+REM CHECKUPD.BAT - Version 1.2
+REM Last modified: 2026-01-19
+REM Changes: Added error logging
+```
+
+**Option 3: Use Git Repository**
+- Maintain batch files in git
+- Tag releases: `v1.2-production`
+- Deploy from tagged versions
+
+---
+
+## FAQ
+
+### Q: How long does it take for updates to reach DOS machines?
+
+**A:**
+- AD2 → NAS sync: 0-15 minutes (scheduled task)
+- NAS → DOS machine: Next reboot (or manual NWTOC)
+- **Total: 15 minutes to 24 hours** (depending on reboot schedule)
+
+For urgent updates, ask test staff to manually run NWTOC.BAT.
+
+---
+
+### Q: Can I update multiple files at once?
+
+**A:** Yes! Copy all files to \\AD2\test\COMMON\ProdSW\ at once. They'll all sync together and download together on next NWTOC run.
+
+---
+
+### Q: What happens if I overwrite a file while DOS machine is downloading?
+
+**A:**
+- If AD2 → NAS sync is running: File may be partially copied, retry on next sync
+- If DOS machine is downloading: DOS gets whichever version was on NAS at start of download
+- **Best practice:** Deploy during off-hours when DOS machines are idle
+
+---
+
+### Q: Can I delete old files from ProdSW?
+
+**A:** Yes, but be careful:
+1. Verify file not referenced by any batch file
+2. Delete from AD2: `\\AD2\test\COMMON\ProdSW\OLDFILE.BAT`
+3. Wait for sync (15 minutes)
+4. File removed from T:\COMMON\ProdSW\ on NAS
+5. DOS machines won't download deleted file
+6. **But:** File remains on DOS machines in C:\BAT\ until manually deleted
+
+To remove from DOS machines:
+- Ask test staff to: `DEL C:\BAT\OLDFILE.BAT` on each machine
+- Or add to cleanup script
+
+---
+
+### Q: What's the difference between COMMON and machine-specific folders?
+
+**A:**
+
+**COMMON (\\AD2\test\COMMON\ProdSW\):**
+- Deployed to ALL 30 DOS machines
+- Use for: Standard batch files, shared programs
+- Example: NWTOC.BAT, CTONW.BAT, CHECKUPD.BAT
+
+**Machine-Specific (\\AD2\test\TS-04\ProdSW\):**
+- Deployed to ONLY that specific machine
+- Use for: Custom configurations, machine-unique programs
+- Example: Special test config for TS-04
+
+**Precedence:** Machine-specific files override COMMON files (downloaded second).
+
+---
+
+### Q: How do I know which version is on a DOS machine?
+
+**A:** Ask test staff to check:
+
+```batch
+REM Check file date/time
+DIR C:\BAT\FILENAME.BAT
+
+REM Check version in file header
+TYPE C:\BAT\FILENAME.BAT | MORE
+```
+
+Or keep a deployment log:
+```
+\\AD2\test\COMMON\ProdSW\DEPLOYMENT_LOG.txt
+```
+
+---
+
+### Q: Can I test sync manually without waiting 15 minutes?
+
+**A:** If you have SSH access to AD2, you can manually trigger sync:
+
+```powershell
+ssh INTRANET\sysadmin@192.168.0.6
+# Run sync script manually (command depends on AD2 configuration)
+```
+
+Otherwise, ask IT to manually run sync task.
+
+---
+
+### Q: What if I need to rollback an update?
+
+**A:**
+
+**Option 1: Restore from Backup**
+```
+COPY \\AD2\test\COMMON\ProdSW\_backup\OLDFILE.BAK \\AD2\test\COMMON\ProdSW\OLDFILE.BAT
+```
+Wait 15 minutes for sync, DOS machines download old version on next reboot.
+
+**Option 2: On DOS Machine**
+```
+COPY C:\BAT\OLDFILE.BAK C:\BAT\OLDFILE.BAT
+```
+Immediate rollback on that machine only.
+
+---
+
+### Q: Can engineers run DEPLOY.BAT remotely?
+
+**A:** No. DEPLOY.BAT must be run locally on the DOS machine:
+- Requires direct access to C:\ drive
+- Modifies AUTOEXEC.BAT on C:\
+- Cannot be run over network share
+
+**Deployment workflow:**
+1. Engineer places files on AD2
+2. Wait for sync to NAS
+3. Test staff runs on DOS machine: `T:\UPDATE.BAT TS-XX`
+
+---
+
+### Q: What files should never be modified?
+
+**A:** Be very careful with:
+
+**System Files:**
+- AUTOEXEC.BAT - Only update via DEPLOY.BAT or .NEW staging
+- CONFIG.SYS - Only update via .NEW staging
+- STARTNET.BAT - Network client config
+
+**Core Update Files:**
+- NWTOC.BAT - Download updates (test thoroughly before deploying)
+- CTONW.BAT - Upload test data (test thoroughly)
+- DEPLOY.BAT - Deployment installer (test on TS-30 first)
+- STAGE.BAT - System file staging (critical for updates)
+- REBOOT.BAT - Auto-generated, don't modify manually
+
+---
+
+## Summary
+
+**Key Takeaways:**
+
+1. **Access via:** `\\AD2\test\COMMON\ProdSW\`
+2. **Sync time:** 15 minutes maximum
+3. **Deployment:** Automatic on reboot (or manual NWTOC)
+4. **Test first:** Use TS-30 or machine-specific folder
+5. **Backup always:** Keep old versions before updating
+6. **Communicate:** Notify test staff of updates
