Maybe that one with potential errors ?

Not even a single VLB slot? This must have been a very weak performer, even with the Cyrix upgrade, since the video and storage performance were limited to ISA.

Hey, sorry to post about another 486 board but I found yet another Socket 3 board at the same recycler. I tried looking through UH99 with no success but maybe I missed something. This one appears to have Solutions and Siemens chipset(s) but I cannot find any reference to other Socket 3 boards with these same chips. The board does POST and it came with the Cyrix DX2 installed, I'm assuming it didn't come with it originally due to the board itself having a date code of 1992.

Can you save the BIOS to a file and post it here ?

I have a old 5v only 486 that will run a AMD or Cyrix DX2 and also ISA only board. They are very common, there are many OEM like P. Bell, Acer, Vtech/PCPartner and few others that used a riser w/o any VLB....
This one appears to have cache (or not, I cannot read the chips well enough to tell but appears it does ;p)

Thanks for the help everyone! I have a 386 system with pretty bad battery damage, for now I think I may install this board into it while I try and repair the original board.

That does look very close (same jumper settings and all), it is a bit smaller than the pictured board though. It is ~255x220 mm.

Will do so once my TL866 arrives =D

I have seen several badly stretched/compressed layouts by now, compared to the real thing. I see the jumper names/locations still kind of make sense, I would call it a match.
