Szadycbr > Mash, Your host CPU have 2 threads to use, PCem using only 1 thread so u got 50% of cpu usage, when you run anything on voodoo u will get up to 100%. Correct!

Hi, i could not install MS-DOS6.22 or start any Win98 HDisk with the IDT WinChip CPU. All Intel CPUs are working. The problem is since (7b8c372) "Move some more variables into cpu_state structure". Config: Award 430VX PCI S3 ViRGE/DX IDT WinChip 200 Cache: A lot Fast VLB/PCI Sound Blaster ...

Same problem here with S3 ViRGE/DX in Win311 (fresh install).
You can't also use the Super VGA (800x600...) mode. It only works with Trident TVGA8900D gfx card.
