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

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

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.
