I have a colleague from old HW, who needs a hand, for a 486 PCI, unfortunately I can't understand what MB it is (Make and model), and this doesn't help me, briefly the card has Socket 3, 3 PCI, 4 ISA, 4 SIMM 72 Pin, and several jumpers, near the CPU, there are probably many others, aesthetically it is quite ok, and there seem to be no signs of corrosion (leaking battery?), the ideal would be to understand if the jumpers are correct, those of the CPU in particular, but also those of the cache.
If anyone can tell me what card it is, this would help a lot, or an image of an identical MB would be enough, from which to see what the jumpers are like. Thank you very much, I hope it is not a rare card, and that I can find some documents (even pdf), certainly a link with various connections would be perfect, perhaps a BIOS compatible with the SiS chipset would help, not necessarily the original one, in case the present one was corrupted.

Looks a bit like an AMI Super Viyager PCI-II. Wait no. looks more like an Lucky Star LS-486E

Looks like the LS-486E rev c (can see it on pic) for sure but no manual on rw for that one, so it might be a case of hoping the rev D is the same or similar enough to get you started.. https://theretroweb.com/motherboards/s/lucky- … lon-d#downloads

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

@PC@LIVE: It would be more useful if you could provide a better picture, preferably without that PCI card in the middle.

~~There is no "Rev:C" at all;~~ Rev:C1/C2 has a very different layout, more like a completely different model than just a revision. OP's motherboard is almost identical to the Rev:D photo on The Retro Web submitted by computerguy096.

Thank you all for your valuable suggestions, I am currently using the luckystar settings, it seems to have also been produced by BEK, the equivalent model is P407, at least that's how it seems.
I'm currently testing out some jumper settings, they should be wrong (some of them), but I'm suggesting the correct settings for a 486 Overdrive DX2-66, so I'll use the settings for a 486DX-33.
I add more photos, unfortunately I don't have the card at hand, the card is not mine, I'm just suggesting the right settings, because the current ones don't work, i.e. the card doesn't start, and the post card doesn't show any code.
