Re: [Freedos-kernel] fix truename and report version 6.22?
Hi all, please check the current kernel updates with Bart's FASTBOOT versus STACKS fix and some DOS 6 compatibility updates from me: Binaries: www.coli.uni-saarland.de/~eric/svn-binaries-freedos.zip Something else: Rugxulo tested the executable-unpacker IUP (ftp.sac.sk/pub/sac/pack/iup067.zip) and found that it fails to rename temp files. I tried, too, and found that IUP gives no temp file name template. FreeDOS behaves as MS DOS 5, it creates the temp file in the root directory. I believe newer and older MS DOS versions would create it in the current dir? Added to FreeDOS: The root dir style is now only used for version 5. Maybe we should report DOS version 6 instead of 5 anyway? Added to FreeDOS: The FAT16 kernel version is now reported as 6.22. I checked for differences in RBIL and found: Other AH in TRUENAME (int 21.60), other temp file names (21.5a :-)), I tried to add that to TRUENAME but it seems to always return 0 while it should return 3a for char devices, could somebody have a look at what I have missed to update? ext country lowercase table (21.6503) in country sys but only for Cyrillic CP866, maybe also int 21.f8/f9 oemint21 hooks. That would be only for the UNSTABLE branch which has more country / nlsfunc support, I guess? MS DOS 6 also comes with newer apps/tools, himem, smartdrv, keyb, dblspace, emm386, other tools. MS DOS 7+ also has a new version check (2f.4a33) and lots of other new stuff. Something in some int 2f.5500 command.com share parts of loaded code between instances is also DOS 6 specific. And so on ;-). To make a long story short: Let us update TRUENAME and MKTEMP and COUNTRY to MS DOS 6 style, and let us change FreeDOS kernel to report that it is version 6.0 or 6.22: This will make DOS apps happy in general and it is easy Done :-).

[Freedos-kernel] fix truename and report version 6.22?
Hi Bernd, I have tested the new kernel a bit in Bochs already. Sample kernel binary: www.coli.uni-saarland.de/~eric/ke2007jul21.zip same filename yet updated release? Yes, it was still 21jul :-). Updated kernel, kept kernel2. Something else: Rugxulo tested the executable-unpacker IUP (ftp.sac.sk/pub/sac/pack/iup067.zip) and found that it fails to rename temp files. I tried, too, and found that IUP gives no temp file name template. FreeDOS behaves as MS DOS 5, it creates the temp file in the root directory. I believe newer and older MS DOS versions would create it in the current dir? As you cannot rename to another directory (or do some MS DOS versions support that?) with DosRenameTrue, the rename fails unless the to-be-unpacked file is also in the root directory. I suggest to change FreeDOS to create temp files in the CURRENT directory, not the ROOT directory, if no template is given for the name. I believe this would clone MS DOS 6 style - according to RBIL, we already use MS DOS 6 A-P instead of MS DOS 6 hex style temp names anyway. Maybe we should report DOS version 6 instead of 5 anyway? I checked for differences in RBIL and found: Other AH in TRUENAME (int 21.60), other temp file names (21.5a :-)), ext country lowercase table (21.6503) in country sys but only for Cyrillic CP866, maybe also int 21.f8/f9 oemint21 hooks. MS DOS 6 also comes with newer apps/tools, himem, smartdrv, keyb, dblspace, emm386, other tools. MS DOS 7+ also has a new version check (2f.4a33) and lots of other new stuff. Something in some int 2f.5500 command.com share parts of loaded code between instances is also DOS 6 specific. Internal KEYB data (2f.ad80) also depends on DOS version. Hm. Did you know FORMAT calls int 2f.adc1 before it asks for a disk, if /SELECT option given, letting a tool called SELECT show another message first? To make a long story short: Let us update TRUENAME and MKTEMP and COUNTRY to MS DOS 6 style, and let us change FreeDOS kernel to report that it is version 6.0 or 6.22: This will make DOS apps happy in general and it is easy for us :-). Other DOS 5 - 6 differences are only outside the kernel anyway :-). FreeDOS with FAT32 support already reports MS DOS 7.10 compatibility, time to fix the rest. Eric PS: Does any interface support cross-directory rename in DOS officially? If so, I would like to add if you rename a directory cross-directory, update .. there :-). - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.
