Wish I had found this last week. I couldn't get an 120GB SSD working with DMA enabled in Win2k on a dual Pentium Pro motherboard (440fx). Bios supports drives up to 128GB. It loaded up in PIO mode, every time I enable DMA in Win2k (440FX only supports up to MW-DMA2) the PC would freeze on the …

I also have an interesting variant of the problem. ECS P5XVBE Rev 3.0. AWEUTIL only worked sporadically. After I installed a boot manager it now works every time. No idea why. A BIOS update to version 1.5 led to the known problem. Then I went back to 1.4. https://www.vogons.org/viewtopic.php?p= …

The issue with VME is only relevant for modern stuff, QEMM works fine with the 486 CPU that you are using. I'm speaking under correction, but I think.. I guess it depends on the system/software. V86 causes a notable slowdown on 386 systems, maybe early 486 systems, too. VME was meant to address …

After reading this thread I still couldn't find a definitive answer to this: - do 815E/EP motherboards (ICH/1/2) support DDMA if using a modified setupds with the correct PCI IDs. Or does the modified setupds only enable SB-Link / PC-PCI on the boards. I have an 815EP (Tualatin) board with YMF724, …

You need to run DSDMA.EXE to compensate for lack of SBLink and DDMA. It requires EMM386 to be loaded first. After it loads successfully, digital sound should work with almost all games (only a handful of games aren't compatible with DSDMA). Have you got a list of the ones that don't work with DSDMA …

Well, the 5x86 I was using was one of the Evergreen upgrade chips that will work with either 5v or 3.3v. I left it at 3.3v and it seemed to work just fine at 160Mhz from the little bit of testing I was doing. Way back in the day when I had an AMD 5x86 in my main system, I was running that at 160Mhz …

What rev AP4 do you have printed on the motherboard. Using latest bios (Award 11/25/97) and a 1GB CF card connected as master to the onboard IDE works for me. This is using a cheap chinese CF > IDE adaptor with floppy power connector. It is slow though, limited to PIO-3, I'm not sure if the onboard …

Largely depends on what motherboard you will use. A ForteMedia FM801 card is probably your most compatible bet that has very agreeable FM music.
