Re: Windows 3.1 DOS Box VGA grabbing

I just tested and it's not working properly on any emulated VGA or later card. What happens is, when you switch from full screen mode to windowed mode, the window incorrectly displays only empty (black) characters, until you either type something (at which point you see the character you just typed...

Re: Bug in switching CDs

I can confirm this happens on my side too, (seems to work OK with a 386 tho, but Win95 doesn't run all that great on a 386).
In DOS it works fine.

Re: Optional: More CPU speed grades.

The interpreter can not achieve anything even remotely like Pentium timing, so please do not try to add it. True, the WinChip emulation has mostly 486 timings, so WinChip 100 basically is as fast as a DX4/100 or Pentium 60/66. Added Intel RapidCAD emulation (Intel's 486DX upgrade CPU for 386 system...

Re: Optional: More CPU speed grades.

I've added very, very early Pentium OverDrive emulation.
It's basically WinChip emulation, but on the 486 boards.

Using this updated file will give you it.

EDIT: Removed file, will work on trueish POD emulation using the rev 180+ pentium emulation.

I'll try to do better emulation tomorrow.

That BIOS most likely isn't for any chipset PCem emulates. Hence why it doesn't work. Yeah most likely.

Finally, networking!
In case of that the CMPXCHG8B instruction is added, could both PNP and non-PNP versions be supported, XP only supports the PNP version, 2000 supports both.

Re: Development screenshots

I was going off the Winchip datasheet, which stated that CMPXCHG8B was disabled due to 'a bug in Windows NT' - from what you're saying this isn't actually the case. I don't think you're missing much though; while XP will run on PCem if CMPXCHG8B is added, it is _extremely_ slow. Yeah, that is true....
