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 …

Hi, I've described here https://www.vogons.org/viewtopic.php?f=25&t=67476 a dual-boot system where the partition type for DOS 6.22 gets changed from 06 to 60, preventing Win98 from messing with it completely. The only change, besides changing the type, is to patch IO.sys to recognize type 60. In …

Well, the Voodoo3 AGP was another videocard that the KT7A did not like. I ran Expendable and it crashed to desktop. I then tried appending "-nocputest" to the game's go.exe with a shortcut, and then the game froze (hard lock) and the system required a reset. I then tested with my Biostar M7VKD and …

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.

Windows 7: - Wikipedia says Intel Broadwell is the last chipset officially supported by Microsoft, but you can find up to Intel 200 series (Kaby Lake) motherboards with Windows 7 drivers - Looks like even NVIDIA RTX 30 series has Windows 7 drivers, I think they've been more like security releases …

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. …

You can try the "minipro" software which is native. It works fine with SPI flash but has trouble with NAND. https://gitlab.com/DavidGriffith/minipro

Sadly SETMUL freezes when I use it to change frequency. Can you share details on your board version (1.0/1.1/1.3) and BIOS? What version of SETMUL do you use?

Unfortunately I can't remember exactly my tests, but from what I read online, that motherboard is not capable of running FSB at 133 MHz.

I'm pretty sure I've traced down the Flatout2 instability to a setting in the KT7A's BIOS called "Enhance Chip Performance" under the "Softmenu III" category... I had to clear the CMOS on this board recently because I was experimenting with different heatsinks and CPUs, and the problem came back. …

From the point of view of the monitor, it cannot easily distinguish 720x400 from 640x400 so all LCD monitors I've tested assume it's 720x400 and you get some doubled pixels. To avoid it you must use additional hardware like the OSSC (it also removes the requirement for VGA input). Many monitors also …

I am also using an NV25, it's the Ti 4200 (clocked lower). This could explain the results indeed. Perhaps the Zalman cooler helps as well.
