...., but can confirm that the TGUI9440AGi PCI will use 2MB properly. That was under Linux. I strongly suspect your bad experiences are more due to poor Win98 support for this 1994 card than the card actually not being able to do it. Do you still know (or have you written it down?), which refresh …

Also, look for Tseng ET4000W32P cards, as they not only use the 2MB for extra modes in Windows but the interleave improves DOS and Windows performance. Avoid Cirrus Logic GD542x cards with 2MB, due to crappy integrated RAMDAC the second MB can only be used for a few eye-melting interlaced modes. An …

Greetings, I purchased a Diamond Stealth based on the vision864 for my 486 to keep it period correct (I have an 8mb 3d Rage of some sort in there, currently.) It arrived and would produce no video and no beep codes. The seller apologized and let me keep it and refunded my money. I then ordered a …

I took the first photo with that memory, but it didn't work. I have tried all the ones that I have not identified, and it does not show video with any of them, so, it is left with 64MB EDO in 4 modules, of 16MB. I understand that they may not be compatible with that motherboard. Thanks again! I …

I'd suggest getting out the candles and dubious red crayons - I fully intend to resurrect that card :P If it's just that one chip that's dead, I can fix it in five minutes once I source a replacement (in fact I might have one knocking around somewhere). I'm more concerned with the motherboard; …

Impressive values for an AMD @ 160 MHz as I never saw any reaching more fps in Quake than 17.7. I got an IBM 5x86-100.

Sorry for a "necro reply". But I am interested in that. What about the extremely good raw DOS performance? Any benchmarks? Doom, Wolf3D? If possible a comparison using Am5x86 would be appreciated, because with a DX2-66 differences are always small. I see some here: https://www.vogons.org/viewtopic. …

Hmm. Not convinced. What was the Bios? You said a pin of the Bios was bent? If yes, then somebody played around with the chip, meaning it was removed and re-inserted. Without a working Bios the board will do nothing.
