Re: [Bug] 800x600x24bpp on the ET4000W32p is messed up

The Windows 3.1 drivers work just fine in Windows 3.0, except for Japanese Windows 3.02 where they don't work. I'm gonna try out the ET4000/W32p Windows 3.1 driver on Windows 3.0 to see if it works or now. :) Update: Okay, Battler. I tried the ET4000/W32p Windows 3.1 driver on Windows 3.0 and every...

Re: FPU on emulation of pre-486 machines...

I'd also like to see 8087/287/387 FPUs available in pcem. BTW the FPU was optional before the 486 DX was released, which is probably why it's not emulated for older cpus.

Re: Any way to change FSB in Pcem?

Success! I edited the Pcem-x source code(the cpu.c file to be exact) to get an Overdrive at 25 MHz!

I've done it in source to have a pentium "underdrive" clocked around 40mhz and 20mhz

As you can see, selecting any Mobile Pentium CPU with the Award 430VX PCI will cause it to be reported as a random 486 CPU. But from windows it is recognized correctly.
