Hi all, this is my first post.

I've recently come across a box of 16 486 motherboards with Intel and AMD DX4-100s from a friend I buy parts off of and I can't identify the board. I need to find some documentation to help me get it set up. There are a few boards I've found which look very similar but none that 100% fit the bill. The board has a UM8498F Chipset and an Award BIOS. Would anyone know what this might be? Cheers.

V1.7 in the top left corner, a typical sign of a PCChips board.

This one in particular is a M912 V1.7

We only have AMI BIOSes documented for it, if you could provide a BIOS dump of your board, that would be appreciated.

Odd, I have a 1.4 and a 1.7 and both have an award sticker on the bios... Can't recall ever having known there were amibios versions for these mainboards.
I'll dump&upload 'm after I finish dinner.

Excellent, cheers. I would provide a BIOS dump but I've not got all the bits on hand to get it running just yet. I was worried as I've heard those boards can have fake chipsets and fake cache soldered to the board but luckily this board has real socketed cache. The main chip is silkscreened instead of having a sticker on it so it doesn't seem fake. Seems to be a fairly nice board.

It has an interesting cache. i mean someone took smaller cache chips and installed them on regular DIP32 sockets. Your board seems fine and has neither fake cache or "fake"/rebranded chipset.

if you look more closely, it's not some DIP32 imitation, the pcb with 4 sram chips covers 4 dip sockets and isn't even using all the pins of every socket.
also the left and right pcb on the photo are different.
this might require further investigation inquiry & insights 😀 (though probably pretty standard)

That's how it works with regular chips as well, look at the 9th chip, it's not using all the pins either. It's normal. They're just smaller (in terms of capacity) chips.

9th chip? you mean the tag ram.
Guess you missed what I was trying to say, the pcb is just not 1 chip to 1 socket. it's four chips to a partial four sockets. that's all.
