Woohoo! I got it to flash! I had to tell uniflash to flash the image WITHOUT the boot block, and that was it! I just flashed the image to an old 2mbit motherboard BIOS chip (using the hot swap method with an old PC Chips M810 SIS board), then I saved the contents to a backup, then compared that with …

Ozz...where you located at roughly.. Let's just say that since I was getting it dumped for archival anyway, that I had 2 copies made as well... Just to be sure. And one of them is for you. PM your contact info... Thanks! I'm still struggling with trying to flash a copy of it myself. I found the …

Awesome! Thank you Crossbow! I have some spare BIOS chips I've harvested from old motherboards. I have one of these: http://www.alphacron.de/download/hardware/39SF020.pdf It is a 2Mbit ROM, the voltage is +5v and pinout seems to match the 27C020 used in the MT200... would it be as simple as flashing …

What you lose with Vista, 7 and anything later is hardware DirectSound 3D support. This means, every hardware-specific feature used by a sound card (EAX, A3D, surround sound, etc.) will not work in anything newer than XP unless the game uses OpenAL natively (not common) or you can get one of the 3rd …

Keep in mind the price. One doesn't merely look for a Rage Fury Maxx and find one laying around. I have only ever seen them for sale at eBay collector's item prices, despite how impractical they are for a retro build. If you find one, it would be a cool thing to tinker with, but its totally up to …

Wow, this is a really old thread. Anyway, I do remember reading that the Trident 8900D is usually a good, fast ISA card. I have one but it blew a tantalum when I tried to test it, so it's awaiting repairs before I can test it myself. 😀

I actually know how to dump roms I just haven't a programmer to read them any longer. I had access to one in the late 90s and missed on the chance to own some very high end ones in the early 2000's when the company I worked from was in the middle of a large move and literally dumped about a half …

Snagged a Prometheus (ARIA16) ISA sound card for cheap. Prior to buying it, I already tracked down a bunch of software, guides, etc. for it. Only thing I am missing is the SSDK and LSDK and the associated documentation. Not sure if I am going to be able to find it as the SSDK was only allowed to be …

And I did ask around, but so far the only person to offer to dump the rom off my mt-200s is in the UK and that would be quite expensive shipping wise. Once I learn how to dump (and successfully program) a ROM on one of mine, I'll do it for you. That 2.01 firmware needs to get online, and I'd love …

My Diamond Stealth 3D 2000 Pro (S3 Virge DX 4MB) has been on the fritz for a year or two now. It started giving me artifacts in Windows 98 (strange lines around the cursor) so I switched to a different card in that build. Today I wanted to try to fix it, so I installed it in my tester system, and …

I would replace the caps, but probably not worry about heatsinks for the VRMs. The K7S5A was never an overclocking board, putting lots of heatsinks around the place is just overdoing things. It was never built as an overclocking board, but with a 3rd party BIOS it does allow for some overclocking. …

Definitely going to want new caps on that board. I replaced the large ones once on mine 8-9 years ago and now some others need replaced. I'm amazed that such a cheap board has lasted nearly 17 years though without any other failures. It was used in three or four different computers up until it was …
