This checkpoint establishes verified deployment infrastructure for the Dataforth DOS Update System with proper file synchronization and documentation. ## Key Changes ### TS-4R Backup and Analysis - Backed up complete TS-4R machine to D:\ClaudeTools\backups\TS-4R\ - Analyzed MENUX.EXE startup menu system (758-line QuickBasic program) - Documented complete startup sequence: AUTOEXEC.BAT → STARTNET.BAT → MENUX.EXE - Found MENUX.BAS source code (Feb 2008 version) from KEPCO ABC software archive ### AD2-NAS Sync Infrastructure Fixes - Created junction: COMMON → _COMMON (single source of truth for software updates) - Verified bidirectional sync logic prevents data backflow: * Test data: DOS → NAS → AD2 → Database (one-way, deleted from NAS) * Program updates: AD2 → NAS → DOS (one-way, files remain on AD2) - Manually deployed correct BAT file versions to NAS after sync connection issues - Verified all 9 BAT files deployed correctly (5.1KB-8.8KB each) ### Deployment Scripts Created - check-junction.ps1: Verify COMMON/\_COMMON junction status - compare-common-folders.ps1: Compare folder contents - deploy-correct-bat-files.ps1: Deploy BAT files from local to AD2 - fix-common-junction.ps1: Create COMMON → _COMMON junction - verify-bat-deployment.ps1: Verify file versions on AD2 - manual-push-to-nas.sh: Manual BAT file deployment to NAS - read-sync-script.ps1: Read Sync-FromNAS.ps1 from AD2 - search-menux-ad2.ps1: Search for MENUX source files ### Documentation Updates - Updated all deployment guides with MENUX startup sequence - Added startup flow to credentials.md and session logs - Documented junction requirement for COMMON/\_COMMON - Added data flow verification confirming unidirectional sync ## Technical Details **Files Deployed to NAS (2026-01-20 09:01-09:02):** - UPDATE.BAT (5,181 bytes) - Machine backup utility - DEPLOY.BAT (5,579 bytes) - One-time deployment installer - NWTOC.BAT (6,305 bytes) - Network to Computer updates - CTONW.BAT (7,831 bytes) - Computer to Network uploads - CTONWTXT.BAT (1,504 bytes) - Text file version - CHECKUPD.BAT (6,495 bytes) - Check for updates - STAGE.BAT (8,794 bytes) - Stage system files - REBOOT.BAT (5,099 bytes) - Apply staged updates - AUTOEXEC.BAT (2,211 bytes) - DOS startup configuration **Sync Logic Verified:** - PULL: /data/test/TS-*/LOGS/*.DAT copied to AD2, then deleted from NAS - PUSH: C:\Shares\test\_COMMON\ProdSW\* copied to /data/test/COMMON/ProdSW/ - No reverse flow in either direction (test data never returns to DOS) **Junction Created:** - Target: C:\Shares\test\COMMON → C:\Shares\test\_COMMON - Eliminates duplicate file maintenance - Backup saved to C:\Shares\test\COMMON.backup ## Files Modified - DOS_DEPLOYMENT_GUIDE.md: Added automatic startup sequence - docs/DEPLOYMENT_GUIDE.md: Updated post-reboot expectations - docs/ENGINEER_HOWTO_GUIDE.md: Added MENUX menu loading step - credentials.md: Documented startup sequence and MENUX interface - session-logs/2026-01-19-session.md: Added startup documentation ## Files Added - 8 PowerShell deployment/verification scripts - 3 HTML documentation exports - TS-4R complete backup (not committed to git) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

|
<p><strong>Location:</strong> C:\AUTOEXEC.BAT on each DOS machine<br>
|
|
<strong>Function:</strong> Machine startup configuration</p>
|
|
|
|
<p><strong>Executes on boot:</strong></p>
|
|
<ol>
|
|
<li>Sets machine identity (SET MACHINE=TS-XX)</li>
|
|
<li>Starts network client</li>
|
|
<li>Calls NWTOC.BAT (downloads updates)</li>
|
|
<li>Calls CTONW.BAT (uploads test data)</li>
|
|
</ol>
|
|
|
|
<hr class="divider">
