You also have IRQ's that the cards are using up that are separate from the Dos settings. Most motherboards show the IRQ usage table during post. Hopefully they aren't sharing IRQ 12 or some other number, usually above 9. In DS.INI in the Yamaha cards Dos drivers folder the INTA IRQ setting has to …

That looks a lot like an Eprom to me, same as my Lucky star motherboard has. I flashed my own eprom for it, but of course I have a eprom burner. Chances are it's a 27c010 128kB chip. You may be able to scavenge an eeprom from another motherboard if You have one, they are usually 29c010 or 29e010, …

My Abit KT7-Raid doesn't have Sblink but I got my YMF724F-V working in pure Dos mode with Dsdma running after setupds in autoexec.bat. It's not perfect though, at least in my system, as Dune 2 didn't have speech, and Pinball fantasies has static coming out the right speaker added to the music/ …

My Abit board (listed in sig) originally had a Duron 650 that I overclocked to 900 with a TNT2 Pro AGP card. Later upgraded to a Ti4200 and then it got relegated to spare computer when I bought a P4. The Duron was a bottleneck with the Ti4200. A good match for the video would be a Gf4 mx440 or the …

GM and Dos4gw games don't go together very well. The other downside to the sblive's emulation is it requires Emm386, and some games don't like that, Pinball Illusions is an example. I also found that Whiplash(Fatal racing) went extremely laggy running in 3dfx mode in pure Dos with my sblive. I'm …

There is no pinout available for that startech connector, that's why You really have no choice here but to get a Cheap multimeter and sort this out that way. if You are going to be messing around with old pc's and other retro computers, a multimeter will be an invaluable investment and help get You …

I think an easy way to figure out the pinout on that startech ps2 connector would be to use a multimeter on ohms setting and put a pin in both ends of the thing and measure until You find out whats what. You already have the ps2 mini din pinout. All You need to figure out is what the wires are at …

I looked that motherboard up. It has a KT400 chipset. That should support Thoroughbred and Barton chips out of the box. I've even got a Barton working in my KT133 Abit motherboard no probs at all after a Bios mod update. As has been suggested already, try another cpu. If still no go then maybe the …

There is no such thing as a Pentium 3 133mhz? Your motherboard looks like it has bulging capacitors, which usually means bad stability issues.

Northwoods don't need any more than the stock cooler, even when overclocked. Prescotts were the problem though. There was an old saying "You don't need a heater when You've got a Prescott"

You are correct, the board is an Epox EP58MVP3C-M. Any insight on what cap it is and whether its important or not would be great. :) Unfortunately my multimeter will not read it in circuit and I'm not going to desolder it to find out. It looks exactly the same as the other ones CB66 and CB65 nearby …

I had it on 1.775v, but It was just for benchmarking, it likely will be stable at a lower voltage than that. Hopefully nforce 2 motherboards have a wider range of multipliers, someone else here will know for sure
