8881F weirdness

I have an Epson ActionPC 2600 (486 with UMC 8881F chipset). I extracted the BIOS EPROM and dumped its content with a Mini Pro. I downloaded PCem 8 (wich I believe is the latest version that supports the 8881F) and put the recently dumped BIOS. Much to my surprise the real computer displays and EPSON...

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


Is it OK if I can make a patch to add this chipset and an Intel Desktop Board (Intel Premiere PCI/II) which supports it?

Re: Future graphics card emulation

how about the Number Nine Imagine 128 or the Video 7 VGA 1024i. How hard would it be to add either of those graphics cards? The Nine Imagine 128 is for editing and CAD I believe and those cards are more difficult to implement, and really worthless. Besides, we all want PCem to play old games, right...

Re: Confused about creating hard drive images and sizes

Heads are NOT fixed, that's for sure. If you click in the dropdown list of fixed HDDs you will notice there are many preconfigured HDDs with different sectors. I didn't test it myself, but I bet that to achieve 127 GB you will need a LBA BIOS or an external HDD controller (I think PCem emulates SCSI...

just a question, would you be ok with an MD5/SHA1 of the correct ROM files on it?
The is no problem to include the MD5/SHA1, the thing is that there is not just ONE valid file. There are many versions of a same ROM and all should work

Re: PCem USB support

Did the i430VX have USB support? I had one back in the day and the pads were on the PCB, but they never soldered a header on the board. I don't recall seeing USB picking up in usage until the P2/P3 eras. Yes, it does, but technically USB is on the southbridge (PIIX3) and USB support indeed begand o...
