Hi, thanks for the detailed post! I don't have much to add to your excellent advice, except that I too can not go above 512 MB (which is already more than enough). Using both a nVIDIA Geforce 4 in combination with Voodoo 3 PCI works great. The main issue is to find a PSU with a strong 5V rail (at …

Hi phantasia, do you mind providing the exact model of the AOC monitor you bought? I personally use the G2590PX as mentioned before, has VGA input, is 70 Hz capable and has several 4:3 options (as well as the rare 1:1 option). It's no longer sold but can be found used. EDIT: it's the AOC 24G2SPAE. …

I'm having problems with SETMUL on a KT7A rev. 1.0. I tried two different CPUs (XP-M 2800+ Barton and a Athlon Mobile/Palomino) but each time I try to change the multiplier, the system just freezes. I changed reg 55h/bit2 to 1, but no difference. Both CPUs work fine on a ECS K7VZA and can be re- …

A cheap option is the AOC G2590PX. It's a 1920x1080 144 Hz monitor that has a VGA input, several 4:3 options and can show a 70 Hz image from VGA without frame dropping (so the 320x200 mode which is really 640x400@70 is shown with correct aspect ratio and no frame drop). It's no longer sold new but …

I have built many retro systems last years and still I think KT7A+Athlon XP-M is the best. Fast enough for newer games and slow enough for older. My Asus P3B-F+Tualatin 1.4GHz comes close but hard to slow down if needed. But Slot1 helps a lot, takes 1min to swap CPU to say P2 Klamath with unlocked …

Many thanks for the detailed post, mockingbird. I have updated the original post with a link to yours, in particular your reporting on PCI video cards preventing multiplier changes is very interesting. Indeed the K8 is quite versatile wrt/ slowdown options, and the TDMA support of the VT8237A makes …

Can you run Windows 3.1? It is difficult to run on modern hardware. On the topic of running DOS on old AMD CPUs, the Athlon 64 is also a decent solution: MSI MS-7253 / K9VGM-V (KM890, VIA8237A) , Athlon 64 X2 5050e, Radeon X800 XL

Well, the Voodoo3 AGP was another videocard that the KT7A did not like. Very odd. I've had a Voodoo 3 2000 AGP in my KT7A (rev 1.0) for years without any issues. And I've played some fairly demanding Glide games on it, including Need for Speed: High Stakes, Deus Ex and Unreal Tournament '99. No …

Cyclone3d, I think doing so you risk causing a short and irreversibly damaging a hard to repair component like the VIA686.

I think I used Rubycon+Panasonic when I recapped my KT7A in 2020, but it was mainly a matter of what was available on digikey at the time. Obviously you want low ESR and the same footprint/capacity. After removing the old ones and testing them at least 1/3 were defective.

Try booting in 286 mode /2. Also consider reducing the amount of memory and disabling multi core / hyperthreading in BIOS. Reduce the frequency.

Agreed this is not a good choice of cpu. I'm actually building a 9800 pro rig right now. I went with an athlon XP 3000+ and using an Asus a7n8x-x nforce 2 motherboard Just of note, you can get very good DOS sound compatibility with the KM890 instead + ESS Solo 1 : https://www.vogons.org/viewtopic. …
