Re: Question about Windows 7
There is a dynarec bug which causes Windows 7 to crash on startup in PCem if the dynarec is enabled. With it disabled, Windows 7 will install and run provided you have a CD-ROM version of the OS.

Re: Windows 7 error with dynarec enabled
As for Vista, it does run but has severe stability issues when the Dynarec is enabled (can't sit at the desktop for more than ~10-15 minutes without crashing, often with STOP error 0xF4), which disappear when the dynarec is disabled and the WinChip interpreter is used.

Re: Windows 7 error with dynarec enabled
I doubt Win 7 will work on any machine that PCem emulate. According to [url=https://support.microsoft.com/en-za/help/10737/windows-7-system-requirements]here[/url] it needs hardware way more powerful. There are various youtube videos showing 7 running on hardware of a similar vintage to the configu...

It doesn't even do that. It just hard-locks at a blank screen. (at least on the emulated 486)

[Patch] CMPXCHG8B for the IDT WinChip
This was something I brought up a little bit back in 2014 before the Pentium emulation was added. Well, it's been three and a half years since then, and with the people who would use CMPXCHG8B requiring applications on PCem just using the Pentium, the issue fell to the wayside. So then, is there CMP...

The config panel not letting you choose EGA is not a bug, as it's locked to EGA no matter what is selected beforehand.

Re: How good it the Voodoo on PCem-X and other stuff to ment
Umm, FYI, PCem-X is no longer being developed, and PCem-X is out of date anyways.
Use PCem-experimental instead if you want the featureset of PCem-X.

I've noticed something with the Phoenix 386 clone. The Phoenix 80386 ROM BIOS will max out at 64 MB (640 KB Base Memory, 64512 KB Extended). If I select RAM to allocate higher than 64 MB, the extended memory counter will wrap at 0 KB as it relies on a 16-bit unsigned integer to store the total amou...

Re: DTK 386SX Clone and Phoenix 386 clone.
BIOS'es differ as to what scan code set they expect the keyboard to be in during POST. Some require untranslated set 1 (such as the AMI BIOS'es), and some Award BIOS'es require translated set 2. Some are fine with whatever the keyboard is set to. That makes perfect sense. Now which file is the one ...
