Re: [Freedos-kernel] Boot drive incompatibility with other boot sectors
The trouble is that most SYSes don't bother to set this value - they just copy the whole data area from the old boot sector and replace only the code and OEM ID. So the FF remains there. Verified. _And_ their boot code reuse this field? Yes. No DOS boot sector trusts BIOS DL value like us... (Because as I wrote it just can't be trusted very much) Well, right now I look at boot code of MS-SYS6, and found, that it not uses 24h offset itself Wrong. The read sector subroutine does use it. See http://www.kzin.com/bootsec/dos5pbra.txt but pass value from there to kernel. So the kernel uses it too, thus it's even more important. I not check what SYS does with original 24h field, but image inside SYS contains 80h value, so I doubt that MS-SYS preserves this field. That the image in SYS contains 80 doesn't prove nothing.

Re: [Freedos-kernel] Creation times
Hi, Luchezar Georgiev escribiÃ: I wonder about those creation time set removals. It looks like your I will consider reverting it, but a config.sys option is overkill. Yes, it is. It'll be difficult to revert it as it leaded to numerous other optimisations. Besides, I already explained why I removed it. Why add back an useless feafure without solid argumentation? (Useless as it was setting creation time on each write.) Unless you can make it set creation times only once, which is difficult. Not speaking about access date, which shouldn't be set in DOS as it would mean unexpected writes. In summary, I didn't do this change only to be reverted back because Bart doesn't like it. Don't apply it to his stable branch, but *leave* it in our unstable, please. The question is: does anyone know what does MS-DOS do? Aitor --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

Re: [Freedos-kernel] Reading new COUNTRY.SYS records
Hola Eduardo, Not really. In the worst case, only the 4 bytes for the empty DBCS table will be unused. The idea is to overwrite the hardcoded tables for CTYINFO, UCASE, FCHAR, and COLLATE and allocate new memory (if needed) for FUCASE, LCASE and DBCS _only_. What about a combination of your (1) and (3) methods - increase static memory only for FUCASE (by 130 bytes or so) and not support DBCS in COUNTRY.SYS? Arkady wrote that MS-DOS 6.2 doesn't support LCASE for codepage 866 either. I don't see the point. You have the array of nlsPointer structures, which tells you where the tables are for each subfunction. If you have a look at nls_hc.asm, maybe it will be clearer. Indeed, now I see an array ot SEG Table? pointers there. Eduardo, let's keep it simple. If you do the changes to NLS_HC.ASM needed to support the *current* information in COUNTRY.SYS, I'll change CONFIG.C as per your (1) and (3) methods. I detest having to dynamically allocate NLS memory in the kernel. Thanks, Lucho --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

no. We want to be compatible with it. That's a subtle but important
difference. It means that we should feel free to implement features in
FreeDOS not present in any other DOS, as long as it doesn't break existing
DOS programs (which of course proved harder than it seems :( ).
The reason why the FAT32 version reports 7.10 is simply because "5.00"
would mislead some programs into believing that FAT32 support is not present.

No way. init_direntry set the creation time equal to the write time but
only for created or replaced files (status != S_OPENED), and in mkdir.
The place where write time starts to be different from creation time is
in
fnp->f_dir.dir_time = dos_gettime();
fnp->f_dir.dir_date = dos_getdate();
in dos_close().
Since you sound so confident I wrote a small program that creates a file
where the creation time is not equal to the write time.

There's nothing religious about this. It's simply a feature.

I don't understand why access dates are different in DOS than other OSes. If the volume is r/o you can't change the access date, sure. I wonder though about this in RBIL: D-216C00- INT 21 - DOS 4.0+ - EXTENDED OPEN/CREATE AX = 6C00h BL = open mode as in AL for normal open (see also AH=3Dh) bit 7: inheritance bits 4-6: sharing mode bit 3 reserved bits 0-2: access mode 100 read-only, do not modify file's last-access time (DOS 7.0) why would a 100 flag be needed if the last-access time would never be modified? > In summary, I > didn't do this change only to be reverted back because Bart doesn't like > it.

So I could have simply reverted your change but decided to be a little more polite and tell you why I don't agree. I just want to say that, if I did not like it myself then I would never have implemented it in the first place... The argumentation given by you was given in the CVS commit -- which I don't think is valid but I understand why in some cases you may not want to fiddle with these times (hence the config.sys idea). Then you have another one (it was broken anyway) by email which I can disprove. Or do I gather from you that you absolutely *need* a kernel that is <40k (exactly why is a mystery to me, but it looks like a ROM where everything but exactly 39.5K is taken up by something else) and that one component now uses one extra sector so you desperately need to shave off another sector?

what is going on? I simply provided a counter-example. Everyone makes
mistakes.
People provide counter-examples to me as well, then you simply
have to accept that, you learned something new, and life goes on. Don't
see this as a personal failure. "fool.dat" was more a tongue-in-cheek
filename, basically I already had a file named foo.dat so played with
that ;)

I see some strange things happening. 1) the kernel version Lucho offers contains a 'time remainig' instead of 'time remaining'. Cosmetic bug (a signle 'n'). 2) DISPLAY loads low (see MEM /C /P), while plenty of (UMB)memory is available, and being the FIRST driver loaded. very strange! 3) DISPLAY loads high and ATAPICDD/CDRCACHE load low, if removing the REM from MEM /C in the beginning of autoexec.bat 4) auto-loadhigh did not seem to work for CuteMouse and SHSUCDX. need to explicitly use LH. 5) MEM /C shows some strange empty thing eating almost all UMB-space, when KEYB partially fails to load (done by explicitly entering wrong codepage info, namely XUS instead of US) 6) As indicated, UDMA must not be loaded into UMB space due to a limitation in the great EMM386 driver. 7) CDRCACHE size may be indicated wrongly (or deprecated), but Eric knows best, I guess. I finally got internet again, so after spending this afternoon reading about 300 emails I'm back again. time to continue some developments. last freedos distro is also 6 months old. sorry guys, summer holidays :) Hopefully this bootable diskette allows everyone to experiment and also see what a full-featured bootdisk looks like (It has about all drivers loaded which FreeDOS provides). can anyone confirm my experienced bugs [1..6] ? below should probably have a DEL MEM_UMB.TXT between line 1 and line 2 but I forgot that. also the DEVLOAD comment is wrong, should be UDMA (+DEVLOAD) hope to get some feedback, Bernd @echo off REM MEM /C > MEM_UMB.TXT LH DISPLAY CON=(EGA,,1) REM MEM /C >> MEM_UMB.TXT rem DEVLOAD requires VDS-support for loading into UMBs by EMM386, rem otherwise crashes the system DEVLOAD /Q UDMA.SYS DEVLOAD /H /Q ATAPICDD.SYS /D:FDCD0001 DEVLOAD /H /Q CDRCACHE.SYS FDCD0001 CDRCACH1 5 MODE CON CP PREP=((858) A:\EGA.CPX) MODE CON CP SEL=858 LH SHSUCDX /D:CDRCACH1 LH CTMOUSE LH keyb XUS,,A:\US.KL MEM /C >> MEM_UMB.TXT --- This SF.Net email is sponsored by: thawte's Crypto Challenge Vl Crack the code and win a Sony DCRHC40 MiniDV Digital Handycam Camcorder.
