This README.TXT file documents the changes made to the PCOS Utilities =============================================================================== v3.90 =============================================================================== Summary Maintenance release. New Features/Changes - Rebuilt with latest PCOS API. - Updated to latest ROM-DOS files (v7.10, revision 4.10.1198). - hexcat: Added "/e" option to generate hex-end-of-file line when a single file is being appended. The hex-end-of-file line is automatically added when two or more files are being concatenated/appended. - runmode.com: Added support for Escape key to bypass run mode switch. This is used by ScadaBuilder to gain control over the target on startup. Checking for the Escape key is set by syscfg. - syscfg.exe: An option was added "/kchk" to enable checking for the Escape key on startup. - sysload.exe: Added "/v" option to override the checking of the BIOS version when doing a BIOS update. Fixed Problems - None. Individual Utility Versions chkcom v1.25 (no functional change) chkint v1.04 (no functional change) chkled v1.18 (no functional change) chknvram v1.01 (no functional change) chkram v3.04 (no functional change) chkrtc v1.18 (no functional change) chksw v1.18 (no functional change) ffs v1.05 (no functional change) hexcat v1.10 (changed) nocon v1.04 (no functional change) nvz v1.02 (no functional change) syscfg v3.10 (changed) sysload v3.10 (changed) =============================================================================== v3.70 =============================================================================== Summary Maintenance release. New Features/Changes - New utilities were added: - chknvram: checks NVRAM for proper operation - nvz: zeroes NVRAM - ffs: flash file system test - Rebuilt with latest PCOS API. Fixed Problems - hexcat: moved version printout to help screen, so version not output to stdout under normal use (ends up in output file that way). Individual Utility Versions chkcom v1.24 (no functional change) chkint v1.03 (no functional change) chkled v1.17 (no functional change) chknvram v1.00 (new) chkram v3.03 (no functional change) chkrtc v1.17 (no functional change) chksw v1.17 (no functional change) ffs v1.04 (new) hexcat v1.03 nocon v1.03 (no functional change) nvz v1.01 (new) syscfg v3.06 (no functional change) sysload v3.03 (no functional change) =============================================================================== v3.30 =============================================================================== Summary Maintenance release. New Features/Changes - Runmode.com has been improved so that it returns an exit code based on the switch position (0 = Run, 1 = Stop), instead of being designed to call user.bat directly. This allows more memory to be available to user.bat and the application program. The autoexec.bat file must be changed accordingly to work properly with the new runmode.com program. The contents of the new autoexec.bat file should look like this: @echo off runmode if errorlevel 1 goto done user.bat :done - A new utility was added, reboot.exe, which does a "soft" reboot of the CPU. - No functional changes to any of the other programs. Fixed Problems - None.
