ecm created |
| | ====== Mid late March work ====== |
| | |
| | **2025-03-23** |
| | |
| | ===== kernwrap ===== |
| | |
| | [[https://hg.pushbx.org/ecm/kernwrap/rev/63844274af7d|Add include path]] so the kernpl module can include files in the ldosboot directory next to it. |
| | |
| | |
| | ===== lDOS boot ===== |
| | |
| | * [[https://hg.pushbx.org/ecm/ldosboot/rev/0d6ff5effce2|Copy kernpl.asm file]] from lkernpl.asm |
| | * Allow building kernpl.asm [[https://hg.pushbx.org/ecm/ldosboot/rev/1179c370d49e|as FreeDOS kernel payload]]. |
| | * Allow building kernpl.asm [[https://hg.pushbx.org/ecm/ldosboot/rev/04b0cd28d156|as Enhanced DR-DOS kernel payload]]. |
| | * Make fdkernpl.asm, drkernpl.asm, and lkernpl.asm just [[https://hg.pushbx.org/ecm/ldosboot/rev/398d20a0d718|include kernpl.asm for the actual source text]]. |
| | |
| | |
| | ===== tractest/listvars.pl ===== |
| | |
| | Add the switch called -%%%%-filter-section= [[https://hg.pushbx.org/ecm/tractest/rev/beb10e035983|to output .tls text belonging to a particular section]]. |
| | |
| | |
| | ===== lDOS kernel ===== |
| | |
| | * Add additional knobs to msbio/msdisk.nas [[https://hg.pushbx.org/ecm/msdos4/rev/b6c157cf04c6|to allow bouncing UMA or all disk accesses]]. |
| | * Put the COMPAT= options in sysconf.nas [[https://hg.pushbx.org/ecm/msdos4/rev/49f1bbe145e0|into a table]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/db5514416f97|Add options for bounce UMA, bounce any]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/39b7d359fc1c|Document new bounce options]] in the manual. |
| | * Add COMPAT= options [[https://hg.pushbx.org/ecm/msdos4/rev/50e3c90d770c|to hide DOSENTRY MCB or first DOSDATA MCB]] (the latter is only in effect if DOSDATAFIRST option was used). |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/f12b42931236|More assume directives]] in msbio/msdisk.nas (reworked some earlier ones too). |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/3a54c42af9af|Fix DS use]] in msbio/msdisk.nas ECC_ERR_HANDLE. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/6d9d50292002|More assume directives]] in msbio |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/bd8aa030548a|Fix CHS hard disk partition login]], used a DOSCODE function from SYSINIT without a proper transfer, causing a crash. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/616ae5767af7|Leave no dead UPB]] if an HDD has no primary partition to log in. |
| | * Work on msbio/msinit.nas [[https://hg.pushbx.org/ecm/msdos4/rev/20ed3733a9c4|assume directives]]. |
| | * On unknown commands in the kernel command line [[https://hg.pushbx.org/ecm/msdos4/rev/3c3417bf5a6f|strip leading blanks for display]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/70519b7f27a6|Update INIT protocol comment]] (using lkernpl module now). |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/8d668506832a|Set default drive]] to the one that lkernpl passes as the load drive. The first int 13h unit match without a hidden sectors match is taken as a preliminary match. An int 13h unit and hidden sectors match is taken as a final match. |
| | * Check that the DOSENTRY stack for DOSDATA/DOSCODE/SYSINIT relocation [[https://hg.pushbx.org/ecm/msdos4/rev/460366142e38|is large enough]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/8b582bf18879|Some more assume directives]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/0cda1de9f8be|Add manual sections]] on booting and supported file systems. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/9572d44faf35|Add assume directives]] to part of msioctl.nas |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/8e2725fe32b9|Fix SET_MEDIA_FOR_FORMAT]] if current DPT segment is not equal to zero. (This bug seems to originate [[https://hg.pushbx.org/ecm/msdos4/file/33044d736e9d/src/BIOS/MSIOCTL.INC#l398|in the 2024 April release]] of the sources, ie the original MS-DOS v4.00 sources.) |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/067c08f268e8|Add assume directives]] to remainder of msioctl.nas |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/966d9f5b81ed|More assume directives]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/55c74fe22224|Yet more]]. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/662a129b0e17|Fix relocate_dpb_late check]] for additional DPBs in same segment. Little potential for trouble. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/b8366c6e39d1|More assume directives]]. |
| | * Fix buffers allocation [[https://hg.pushbx.org/ecm/msdos4/rev/994ef7584893|to not try to normalise HMA pointer with segment FFFEh]] if the allocation stretches up to 48 KiB within the HMA. This wasn't usually hit but with ''append files 255'' it can be. While we did detect the invalid normalisation, it did lead to a system halting OOM error, so not nice. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/a7bf97226246|Remaining assume directives]] in sysinit1.nas |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/ead3591f54e8|Assume directives]] in sysinit2.nas |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/2790ab6f2528|Preserve open mode]] if AUX or PRN open fail and NUL is opened instead. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/b3bc8e2f2294|Update msdos original source files' assume directives]]. |
| | |
| | This leaves some files in src/INC/ and the lDOS *.asm source files for msbio and msdos for fixing assume directives. After that we can try making use of them in listvars.pl |
