Re: IBM 300GL - 6282

I'm trying to add a new computer - IBM 300GL model 6282 - It has the 430VX chipset (already emulated) and the PC87307 Super I/O (only the PC87306 has been coded) I tried to compile the new model using the PC87306 Super I/O but doesn't work. When I try to run the new model the emulator quits - I sea...

Re: 768kB RAM on Generic Turbo XT

The extra 128kB should be accessible as conventional/base memory if you're using MDA/CGA/Hercules video. EGA/VGA and later will render it inaccessible.

Re: Weird ram problem

That's normal. PCem generally limits RAM to what would be possible on the real system you've selected.

Re: v15 released!

I'd forgotten to actually test that, so I'm glad to see the K6 timings are accurate enough to break Win95a.

Re: v15 compatibility & bug list (WIP)

You can see how much CPU time the Voodoo threads are taking in the PCem status window. The percentage before the frames/sec line is the FIFO thread (though I think this is a grotesque overestimate, and counts the time this thread waits on the render threads), the two percentages below frames/sec are...

Re: v15 released!

Not a lot for the most part; the main CPU load is the CPU emulation, and that's strictly single threaded. The only reason to go past 4 cores is if you want to emulate a Voodoo 2 SLI setup, as the Voodoo emulation can use up to 3 threads per card.

Re: Fake AMD K5

One of the problems with implementing timing for the K5 is that AMD never publicly documented what actually changed between the SSA/5 and 5K86 - and clearly there were some major changes, given how different the per-clock performance on the two cores is! At some point I need to sit down with both ch...

Yes. It's mainly a matter of time and energy, and I don't have any of the latter left at the moment!

Re: v15 compatibility & bug list (WIP)

Rev 1449 should fix the CMDFIFO issues. Turned out to be an MMX bug, triggered by Creative's AudioPCI drivers using MMX/FPU in the background - which the drivers included in Windows ME apparently don't. Seems VIA can be let off the hook for this one.
