Re: 8881F weirdness

Probably a DIP switch or jumper or something on the main board determining which OEM the board is today.

Re: [Patch] Intel PIIX3 southbridge (including USB controller)

Sorry for taking so long to comment on this! My main reaction is that I don't think the PIIX3 should be completely separate from the existing PIIX; apart from the USB controller the two are basically identical, so let's keep the existing code unified for the sake of maintainability. I'd be happier i...

Ah, ok. Strange they'd keep it in the 'Trio' family. Thanks for the info :)
My guess is that ViRGE had quite a bad reputation but Trio64 was quite popular in the business market, so they switched name. That's marketing for you...

Re: Future graphics card emulation

Two reasons the onboard video isn't emulated on Endeavor (Zappa doesn't have onboard video); firstly, it's a Trio64V+ rather than the regular Trio64 that PCem currently emulates. Secondly, I've not seen any dumps of the onboard video BIOS, which probably isn't the same as you'd get on a PCI card. I ...

If the card you're thinking of isn't listed then it probably isn't interesting enough to be worth emulating.

The wxWidgets internationalisation page shermanp linked to looks useful as a starting point. Unfortunately a lot of PCem's GUI was ported from Win32 to wxWidgets using a wrapper (see wx-utils....

Re: documentation rework

Yeah, that's looking good to me. I know documentation has been an issue for many people so an alternative perspective on it is good!

Links are mostly okay, but note one of them links to a site with ROM images, which is something I'd rather not have.

Re: [PATCH] Fix various Linux build issues for Fedora 32

Merged 1571-1575. 1568 is no longer relevant (though a Git equivalent might be handy), 1569 is redundant as an equivalent change is in place, and I don't think I personally agree with 1570.

Could you please restore the old patches in the ET4000 thread? I would prefer to deal with smaller patches containing individual changes rather than mammoth patches collecting a whole bunch of changes together; they're much easier to review.

Re: More SCAT chipset machines

Hmm, this patch feels like it needs some rework to me. I don't like the level of over-engineering in cpu_set_nonturbo_divider(); there's not really a need for the level of bounds checking (who's passing values > 16384 anyway?), and I don't like the use of a magic number for 2/3 (which isn't even sup...

Re: ps2 model 50 seems locked to 2mb

Hmm. I was going to say that PCem should be creating memory boards to expand above what the motherboard allows. However, a quick look at the code shows that this was never implemented for the model 50, only the 70 and 80. In which case 2 MB is the real maximum for the current release. Sorry! I will ...

Voodoo 5 documentation is missing all the register definitions, so is not useful for emulation.

Like I said, I'd need to be convinced that such an approach would be truly reliable. An emulation that only works on some drivers but not others wouldn't be very useful.
