there should be a jumpersetting for dual voltage operation. try setting it from p54c to p55 and the mmx-cpu should work.

good luck!

//edit: i just took a look at the board - i doesn't seem to have this jumper..

I can not believe 😅 I incorrectly configured jumpers for bus speed and processor speed 😦 😦 , the correct setting is just the reverse of what I had jumped. I thought the PIN 1 of this strip jumpers started at the bottom (which is where silkscreened "JP5 JP6 ...") but it was at the top.
Would have to spend more time to test the settings. But I have to do the assembly at work ... I can not spend much time. 🙄 🙄 🙄 🙄 🙄 🙄 🙄 🙄

Yes! but It's more like a love-hate relationship, love when works, hate when works too 😁 but I like old stuf... 486, pentium ... It reminds me my early days in computing.

hehe, i did the same years ago on a pc-chips m577 mobo.. i jumpered just the complete opposite of the correct settings. well that may happen when you are concentrating at more than one thing at a time..

great that it works now.. do you want to put a voodoo card in it? sounds like a solid retro machine for late dos / early voodoo games, but you may consider upgrading the cpu to maybe 266 or 300 mhz to play the most demanding dos games in svga.

A Voodoo3 3000 AGP and K6-2@400, in the near future... But now I want to test a triple core S3 Vision864 (1 chip to manage every basic color - RGB ) PCI under Win95osr2.

That would be a very capable couple. the 5agm2 supports the k6plus-series of cpu's, so you could use a k6-2+ or 3+. the main advantage is the per-boot changeable multiplier if you require low speeds for old games. that can be very effective in addition of different possible cache settings. you can easily go as slow as a 386! and as fast as a k6-3 cpu gets (great for voodoo3).
