[Freedos-kernel] [announce] kernel 2035 and bye
Hi, I've uploaded kernel 2035 to http://sourceforge.net/project/showfiles.php?group_id=5109 important fixes: Fix problems with USBASPI.SYS, DI1000DD.SYS Fixed invalid opcode with debug foo.txt, same with netware redirected logins. Don't move the EBDA by default. Use switches=/e:-1 if you want the auto-sized movement (#1771) Made int21/ah=25,35 reentrant. Solves problem with Intel PRO/1000 driver. Fix dir corruption bug if you delete the first entry in the root directory on FAT32. Fix non-working F5/F8 for autoexec.bat (#1777) With this I'm leaving FreeDOS for the next couple of months at least. I may put up an update for MEM but that's it. There was a bit of noise on the mailing list but the main reason is that I'm generally happy about the kernel, all I wanted in the beginning is to get it to cooperate nicely with DOSEMU. That's done and more. Squeezing even more bytes out of the kernel and fixing even more bugs is certainly possible, but it's time to leave that to someone else as my (volunteer) job is finished.

Re: [Freedos-kernel] [announce] kernel 2035 and bye
Hi, It's sad to hear that you say bye, but hopeful to read that you mention at least a break for two months, although I understand your reasons. Could I ask you something before you go? Could you please review bugzilla and try, as far as you understand/know about it, leave the kernel bugs in a state that represents current kernel 2035? (i.e. close the bugs that have been fixed, for example). If you haven't already done this, of course.

[Freedos-kernel] config.sys problems with 2.0.34 and 2.0.35
A while ago I reported a problem I had with FreeDOS kernel 2.0.34 and PXELINUX+memdisk: http://www.mail-archive.com/[EMAIL PROTECTED]/msg00761.html Well, I have some more information. First, the problem only happens on certain machines. Right now, I can only reproduce it on a Dell Dimension 450. Second, and more interestingly, the problem has changed with the release of 2.0.35. It still only happens on my Dimenstion 450. But instead of not reading config.sys at all, I receive an error whenever config.sys processes a DEVICE= or DEVICEHIGH= line. For instance: CONFIG.SYS error in line 4 DEVICE=himem64.exe ^ ...and so on, one for each DEVICE= or DEVICEHIGH= line. I tried using DEVICE=A:\himem64.exe and the same thing happened. Once I get to a DOS prompt, dir himem64.exe shows that file is present. But I suspect something about the way files are read during processing of CONFIG.SYS is different than how they are read once I get to the command prompt. Again, this only happens on one machine. So I know the problem is not in my config.sys file, although I am appending it below anyway. Since the behavor improved between 2.0.34 and 2.0.35, I am hoping this will ring a bell with someone and make this easy to fix. This is blocking me from upgrading beyond 2.0.33. As always, I am ready to do whatever testing you need. Thanks! - Pat == config.sys == LASTDRIVE=Z DOS=HIGH,UMB ;; Pick exactly one of these XMS providers DEVICE=himem64.exe ;DEVICE=A:\fdxxms.sys bios ps ;DEVICE=himem.sys /testmem:off ;; UMB provider ;DEVICE=umbpci.sys DEVICE=emm386.exe NOEMS ;; MSCLIENT networking gadget DEVICEHIGH=\net\ifshlp.sys ;; Required for installing XP under VMware.

May cause to move all buffers low. Fixed.
Note: because 0xfff0 here is not a _size_, but a pointer (also as HMAFree is
a _pointer_), you _can't_ allocate all HMA space up to and including the

Hm. I check MS-DOS 6.22. For INT21/3301/DL=2 I receive DL=0 (FreeDOS
incosistent), then INT21/3300 returns DL=0 (consistent). Same for DL=3. I
think, for full consistency DL change should be added into INT/3301:
/* DosVars - get/set dos variables */
case 0x33:
switch (irp-AL)
{
/* Set Ctrl-C flag */
case 0x01:
break_ena = irp-DL 1;
+ /* fall through */
/* Get Ctrl-C flag */
case 0x00:
irp-DL = break_ena;
break;
(Here 0x00 and 0x01 swapped and `break' removed).
