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...

I know. It worked pretty well for a while but the laptop eventually started locking up after logging in.
The behavior would be XP throwing a trap exception before the boot splash could even show up.
It doesn't even do that. It just hard-locks at a blank screen. (at least on the emulated 486)

This was something I brought up a little bit back in 2014 before the Pentium emulation was added.

Umm, FYI, PCem-X is no longer being developed, and PCem-X is out of date anyways.

As far as I know, it's the part of the ct486 driver that is found in MAME. I don't think that the CS4031 emulation has been emulated at this time. But other than that, the machine works as is.
Why would you need more than 4 HDDs or even want the Bochs BIOS?

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 ...
