Hello,

I have acuired this motherboard lately, but it was completely non-configured (someone stole some jumpers), I cannot find anything regarding this mobo, I looked at stanson and on http://www.win3x.org/uh19 but no luck :/ Configuration described on mobo itself is vaque and does not cover every jumper.
I have configured it (i suppose) for the AMD CPU (different than this SX)but it hangs on C6 code (cache), but cache is hard configured and I could not even disable it manually by desoldering jumpers.

Hi,
The Ultimate Hardware 2019 has changed names to Ultimate Retro and then merged with The Retro Web. We can now be found from the link to the partial manual of this board:

I hope that + the pictures I found elsewhere give you enough clues to have this thing booting.

And yes, we would like a bios backup from it :D
