QUICK START GUIDE
================================================================================

If you're in a hurry and just need to fix UPDATE.BAT:

1. READ THIS FIRST: README_DOS_FIX.md (5-minute quick fix section)

2. DEPLOY: Copy these 4 files to DOS machine:
   - UPDATE.BAT -> C:\BATCH\UPDATE.BAT
   - AUTOEXEC.BAT -> C:\AUTOEXEC.BAT
   - STARTNET.BAT -> C:\NET\STARTNET.BAT
   - DOSTEST.BAT -> C:\DOSTEST.BAT

3. CONFIGURE: Edit C:\AUTOEXEC.BAT on DOS machine:
   - Change SET MACHINE=TS-4R to correct machine name
   - Save and reboot

4. TEST: Run DOSTEST on DOS machine
   - Fix any [FAIL] results

5. USE: Run UPDATE command
   - Should work automatically using MACHINE variable

For detailed step-by-step, see: DEPLOYMENT_GUIDE.md
For troubleshooting, see: README_DOS_FIX.md or DOS_DEPLOYMENT_GUIDE.md

================================================================================
RECOMMENDED READING ORDER
================================================================================

For quick deployment:
1. README_DOS_FIX.md (5-minute quick fix)
2. DEPLOYMENT_CHECKLIST.txt (follow the steps)
3. DOS_DEPLOYMENT_GUIDE.md (if you encounter problems)

For understanding the problem:
1. DOS_FIX_SUMMARY.md (what was wrong)
2. DOS_BATCH_ANALYSIS.md (why it was wrong)
3. DOS_DEPLOYMENT_GUIDE.md (how to fix it)

For technicians deploying to multiple machines:
1. DEPLOYMENT_CHECKLIST.txt (print one per machine)
2. README_DOS_FIX.md (keep handy for reference)
3. DOS_DEPLOYMENT_GUIDE.md (troubleshooting guide)

================================================================================
FILE TRANSFER METHODS
================================================================================

How to get .BAT files from Windows PC to DOS machine:

Method 1: Network Drive (Easiest)
- On Windows PC: Copy files to T:\TS-4R\UPDATES\
- On DOS machine: COPY T:\TS-4R\UPDATES\*.BAT C:\

Method 2: Floppy Disk
- On Windows PC: Copy files to formatted 1.44MB floppy
- On DOS machine: COPY A:\*.BAT C:\

Method 3: Serial/Null Modem Cable + Kermit/LapLink
- Transfer files via serial connection
- Requires appropriate software on both ends

Method 4: Manual Creation
- On DOS machine: Use EDIT to type in batch files manually
- Reference: Print batch files from Windows PC first

================================================================================
MACHINE-SPECIFIC CONFIGURATION
================================================================================

Each DOS machine needs a unique MACHINE name in AUTOEXEC.BAT.

Example machine names:
- TS-4R  = 4-channel RTD test system
- TS-7A  = 7-channel thermocouple test system
- TS-12B = 12-channel strain gauge test system

Configure in AUTOEXEC.BAT:
SET MACHINE=TS-4R    <-- Change this for each machine

Backup location becomes:
T:\[MACHINE]\BACKUP
Example: T:\TS-4R\BACKUP

================================================================================
TESTING VERIFICATION
================================================================================

After deployment, verify these work:

Boot sequence:
[ ] Machine boots to DOS
[ ] AUTOEXEC.BAT runs automatically
[ ] Network client starts
[ ] T: and X: drives mapped
[ ] No error messages

Environment:
[ ] SET MACHINE shows correct machine name
[ ] SET PATH includes C:\BATCH
[ ] T: drive accessible (T: then DIR works)
[ ] X: drive accessible (X: then DIR works)

UPDATE.BAT:
[ ] UPDATE command works from C:\> prompt
[ ] Backup completes without errors
[ ] Files appear in T:\[MACHINE]\BACKUP\
[ ] Second run only copies changed files (faster)

Error handling:
[ ] UPDATE shows error if network unplugged
[ ] UPDATE shows error if T: unmapped
[ ] UPDATE shows error if MACHINE variable not set
[ ] Error messages are visible (don't scroll off screen)

================================================================================
TROUBLESHOOTING QUICK REFERENCE
================================================================================

Problem: "Bad command or file name" when running UPDATE
Fix: SET PATH=C:\DOS;C:\NET;C:\BATCH;C:\

Problem: MACHINE variable not set after boot
Fix: Edit C:\AUTOEXEC.BAT, add SET MACHINE=TS-4R, reboot

Problem: T: drive not accessible
Fix: Run C:\NET\STARTNET.BAT

Problem: Network doesn't start at boot
Fix: Check network cable, verify STARTNET.BAT in AUTOEXEC.BAT

Problem: Backup seems to work but files not on network
Fix: Check SET MACHINE is correct, verify T:\[MACHINE]\BACKUP exists

For complete troubleshooting, see: DOS_DEPLOYMENT_GUIDE.md

================================================================================
AUTOMATIC BACKUP ON BOOT
================================================================================

By default, UPDATE.BAT does NOT run automatically at boot.

To enable automatic backup:
1. Edit C:\AUTOEXEC.BAT
2. Find section "STEP 6: Run automatic backup (OPTIONAL)"
3. Remove "REM " from these 3 lines:
   ECHO Running automatic backup...
   CALL C:\BATCH\UPDATE.BAT
   IF ERRORLEVEL 1 PAUSE Backup completed - press any key...
4. Save and reboot

Backup will then run automatically after network starts.

To disable:
1. Edit C:\AUTOEXEC.BAT
2. Add "REM " back to the 3 lines
3. Save and reboot

================================================================================
BACKUP RETENTION AND MANAGEMENT
================================================================================

UPDATE.BAT uses XCOPY with /D flag:
- First run: Copies all files (slow)
- Subsequent runs: Only copies newer files (fast)
- Old files on network are NOT deleted
- This is incremental backup, not mirror/sync

To clean old backups:
1. Connect to T: drive from Windows PC
2. Navigate to T:\TS-4R\BACKUP
3. Delete old files manually
4. Or delete entire directory and let UPDATE.BAT recreate

To do full backup again:
1. Delete T:\TS-4R\BACKUP directory
2. Run UPDATE.BAT
3. All files will be copied fresh

================================================================================
DEPLOYING TO ADDITIONAL MACHINES
================================================================================

To deploy to other Dataforth test machines:

1. Copy the same 4 .BAT files
2. Edit AUTOEXEC.BAT for each machine's specific name
   Machine TS-7A: SET MACHINE=TS-7A
   Machine TS-12B: SET MACHINE=TS-12B
3. Everything else is identical
4. Each machine backs up to its own directory:
   TS-4R  -> T:\TS-4R\BACKUP
   TS-7A  -> T:\TS-7A\BACKUP
   TS-12B -> T:\TS-12B\BACKUP

================================================================================
VERSION HISTORY
================================================================================

Version 1.0 (Original) - Failed
- Used %COMPUTERNAME% variable (doesn't exist in DOS)
- Checked T: drive incorrectly
- Had /I flag (not supported in DOS 6.22)
- Used %ERRORLEVEL% variable (should use IF ERRORLEVEL n)

Version 2.0 (This package) - Fixed
- Uses %MACHINE% environment variable from AUTOEXEC.BAT
- Properly tests T: drive with DOS 6.22 compatible method
- Removed all Windows-only features
- Complete error handling
- Comprehensive documentation

================================================================================
SUPPORT AND ASSISTANCE
================================================================================

If you encounter issues not covered in the documentation:

1. Run DOSTEST.BAT to diagnose configuration
2. Check DOS_DEPLOYMENT_GUIDE.md troubleshooting section
3. Verify physical connections (network cable, power)
4. Test NAS server from another machine
5. Review PROTOCOL.INI network configuration
6. Check D2TESTNAS SMB1 protocol enabled

Common issues and fixes are documented in:
- DOS_DEPLOYMENT_GUIDE.md (most comprehensive)
- README_DOS_FIX.md (quick reference)
