Thanks again!

I'm using the Trident TGUI9440 driver for the AMI WinBIOS 486 machine (Intel 80486 33MHz w/16 MB RAM, Sound Blaster 16 sound card) and since I updated to PCem v9 r304, I'm starting to notice display corruption issue when running MS-DOS 6.22 in text mode. Have a look: TGUI9440 text mode display corru...

Flight Simulator 5.1 no longer hangs or crashes PCem v9 on exit with r304! :D The bad news still is that Microsoft Defrag and Norton Speedisk both do not retain the correct colours after exiting Microsoft Space Simulator. It must be either something with the S3 Trio compatible adapters or bugs in th...

Thank you!

There is no r304 debugger version of PCem. I'll be reporting any problems that may arise in r304 once it occurs.

The latest version of PCem is version 9. You can find it on the Downloads section. The latest revision that I currently have installed is r292 and sadly, I will be stuck at this revision, until either v10 is released or someone complies the latest revision of PCem v9.

Also, JPEG images messed up in IE, Windows 9x and 2k/XP. On 16-bit or 24/32-bit color mode. I tried a couple of video cards and none of them could get rid of this issue. I'm wondering if JPEG images in Windows NT (3.1, 3.5x and 4.0) has the same corruption issue as well. Windows 3.0 and Windows 3.1...

Thank you for fixing the bugs in OS/2 1.3 and OS/2 2.0. Once I update to r301, I will do a test installation of OS/2 Warp 3 and if there are any problems, I will report back.

Does anyone have a problem running the latest revision of PCem v9 using the Direct3D video mode? For me, I'm currently running the Award SiS 496/497 machine (486DX2 @ 66 MHz with 64 MB RAM, Number Nine FX graphics card with 2 MB VRAM) for example. Text mode and ironically, Windows 3.11 in 1024 x 768...

Incidentally, I now officially hate OS/2. And also the concept of conforming code segments.

Aww. Why do you dislike OS/2, including the concept of conforming code segments?

TomWalker wrote:Rev 297 fixes the OS/2 1.3 disc error bug.

Thank you for fixing the disk error bug when attempting to install OS/2 1.3. If I update to r297, I'll test OS/2 1.3 and Warp 3 to see if the disk error bug is gone.

I think that we have a bigger problem here and it has to do with the OS/2 operating system itself. 1. OS/2 1.3 OS/2 1.31 installer stops on the first diskette install with the error message after displaying the text splash message: A disk read error occurred. Insert a system diskette and restart the...

I would also like to see SLiRP networking support (ported from QEMU)! :) That way it would be much easier to go online in PCem. Not only I would like to see NE2000 network cards implemented, I would also like to see AMD PCNET Family Ethernet (PCI/ISA). Here's a documentation on networking: http://wi...

Thank you so much for fixing the emulator hang! I really appreciate it! Once I update to r295, I will do further debugging and testing whatever or not if Flight Simulator crashes PCem on exit or hangs and get back to you.

Can you post your config.sys and autoexec.bat files? Sure. Here's what I have so far. CONFIG.SYS: FILES=50 BUFFERS=10 FCBS=1,0 STACKS=9,256 DOS=HIGH,UMB DEVICE=C:\QEMM\DOSDATA.SYS /INITBASE=1101 DEVICE=C:\QEMM\QEMM386.SYS RAM BE:N FR=D000 I=B000-B7FF R:3 DEVICE=C:\QEMM\DOS-UP.SYS @C:\QEMM\DOS-UP.DA...

Can you give more details about your setup? What machine, CPU, graphics card, OS etc? Are you running interpreter or recompiler? I forgot to put this down.

Anyone played Microsoft Flight Simulator 5.1 under PCem? I played that game for a while and the game does work fine for as long as I remain in the game. I exit the game once and it works well. Sometimes when I enable XMS support for the Sound Blaster 16 card Flight Simulator 5.1 does NOT start for a...

Now working in rev 291. Thank you so much for fixing this bug! I deeply appreciate it! :D Update: I got DESQview/X working in higher resolutions! To get it to work, I had to manually edit the DVX.CFG file in the C:\DVX directory with the following: client dwm,backdrop type VG8 dispsize 240x180 font...

QEMM doesn't run on v9. I fixed it last night, in rev 290. DESQview has/had the same issue, I haven't tested DESQview/X yet. Thank you for telling me. QEMM did run on v8.1 though. I suspect that one of the reason why QEMM didn't run is the REP instructions in 32-bit mode with both 0x66 and 0x67 was...

I sure hope that bug gets fixed soon. The bug is not present in Norton Commander v5.51 (released in 1999), the last version that supported MS-DOS. I tested it on a Award SiS 496/497 BIOS (486SX, 486SX2, 486DX, 486DX2 and 486DX4) and it found no problems.

Does anyone have a problem trying to install and run DESQview/X under PCem v9 r285? The product from the defunct company Quarterdeck Systems used to work on PCem v8.1 as well as the latest versions of the MAME arcade and console emulator. Anyways, I have a problem when attempting to install DESQview...

Thank you for telling me about this issue regarding the infinite memory count bug. I sure hope that it will be fixed in a future revision.

Has anyone used the Intel Advanced/EV Endeavour ROM under using the standard (IDT Winchip) and dynamically complied (Pentium/Pentium MMX) versions of PCem? In that case, there are a couple of annoying bugs to look into and it has to do with the BIOS. First issue: When I hit F1 to enter the CMOS setu...

Does pressing another key with it work? Like Alt+F for the File menu? I know that a lot of old DOS applications worked that way. Pressing Alt alone did nothing. Nope, it does not. It sounds to me like my keyboard was starting to act weird. Last November, the Alt and Windows keys were swapped on my ...

Updated to r285 and the ALT key still does not work.

Is anyone experiencing with this problem or is it just me?

It is strange. However, this only applies to the first revision of the SiS 496/497 chipset. The 3rd revision of the SiS 497/497 chipset released on 7 October 1995 fixed the 4,096 cylinder (1.97 GB) bug. It has a file name of SIS496_3.AWA. To get it work with PCem, I had to rename it to SIS496-1.AWA....

I'm currently using revision 279 of PCem v9 using the Award SIS 496/497 BIOS, created a hard disk with 4,064 cylinders, 16 heads and 63 sectors per track, went to the BIOS, used the auto-detect feature to detect the hard disk image. The auto-detection feature can detect a hard disk using option 1 f...

I have a problem here, I'm currently using PCem v9 r279 with the Award SiS 496/497 ROM, I installed MS-DOS 6.22 and Windows 3.1 so far.
