Hi everyone!

I'm trying to identify one of the random 486 motherboards I have in my stash but I need help.

I can't look at the BIOS string because I can't get the thing to boot. It might just be a dead board, but it could just as well be the wrong jumper settings for the CPU I have available.

The attachment 486MB.jpg is no longer available

It looks really close to this board:

But my board has a SiS chipset, and the bios chip is in a different place.

Of course, the boards might not be related in any way and it might just be a reference design...

Help!

Dare I ask you to reveal your search-fu secrets, oh jedi master?

google the following: site:stason.org 486 sis

select images

look for the one that looks like what you have. You can add details to the first line if you can.

It is a mistake to think you can solve any major problems just with potatoes.

by the way, look at the memory configuration. It is 0/1/0/1/0/1/0/1 Thats rather uncommon for a 486 board. That's likely the reason its not posting.

I've been scanning stason images until I got cross eyed. 🙁

Cheers! And thanks again for the help!

Lucky bob needs his own portal. He is the missing google extension. Just add the luckybob extension to you chrome web browser. 😊

I can never figure out how to find those manuals , jumper setting ,and drivers for old components.

Vogons should create there own search engine for old drivers, manuals, bios, and stuff.
And call it “Lucky Bob”
Or at least have a lucky bob option like google has a “feeling lucky” option.
Wasn’t “Bob” a Microsoft Windows assistant ?

You have two leads touching like a knee-caps touching on one of these chipsets.

Good eye ! I see it now, top right SIS chip on the left top side.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

I was going to ask: not the lighting but then I saw the top lead is slightly bent.
