Bios: AMI
System BIOS date: 07/25/94
Bios ID String: 41-P001-008021-00101111-072594-UMC880


It's a Socket 3 board with 4 PCI and 4 ISA slots.

Also, "MG Product" can be read on the board...



I've been searching for this for about two years now and I've found NOTHING :?

Our database mentions an MG board as being an ACER 486, but this isn't much help I suppose.

When I hear Acer i'm thinking desktop computers with integrated stuff...

My mobo is a standard baby AT 486 mobo. Only thing integrated is the IDE controller.

Do you have a scanner or digital camera? Could you provide a good quality image of it here?

Note: our database also mentioned a PCCHIPS board as being sold as MG. But I was doubtful. I then found a Russian site ( http://www.ase.ee/rus/techsupport/drivers.html ) with an AWARD BIOS for an "MG Product" board (i430VX though), and guess what:
05/27/96-i430VX-2A59Ht5AC-00
...this was indeed a PCCHIPS BIOS.

You might have a very early BIOS release for the M915i, though I'm not too sure:

I don't have a digital camera myself, but I can probably borrow my bro's.


And that m915i isn't very similar with my board. Mine doesn't have any VLB slots and the ISA slots are black. Also, the CPU socket is turned the other way with the thicker part with the text 'socket 3' is outside of the PCB, like this:

As I said, I'll try to take a picture of it. Thanks for the help so far. :)

Edit:

This is probably the closest I have gotten in finding anything about my mobo. The CPU socket is positioned in the same way, but mine is at the bottom, like most other 486 motherboards. This one's also a lot smaller. Mine has got 4 simms, 4 ISA etc...

U.S. Technology is the brand.
MG-486PCI02 is the model, I believe.

Would this bbs post regarding the jumper settings match your board?

Very interesting. I'll see if the info is accurate, which I do believe it is. because the anti-static plastic that covers the back of the mobo has 'U.S Technology' on it.


Thanks! :)

Well I checked with the jumpers and no, it's not the right one. The jumper settings in the document don't match with the ones on the mainboard... :?

Strange thing is that the BIOS ID string that was in the document is the exact same one that is on my mobo. Still, the jumper settings didn't make any sense...

How about this other post here?

The jumper numbers are totally different.

Hmm... no that's not the one either. That's a Vesa Local Bus mobo. Mine's got only ISA and PCI.


The previous one was more accurate than this one :?

I thought myself that the previous link you gave was the right one, but as I said the jumper settings didn't match for the previous "manual" you posted. For example, it said that the Reset SW connector was on JP31, but on my mobo it is on JP24...


It's like this mobo just doesn't exist... :?



Do you have any idea where I could find info about this 'U.S Technology' manufacturer (or whatever it is)? I've got a Pentium Socket 5 mobo that has 'U.S Technology' on it as well.

Could you post the full BIOS string of that Pentium mobo?

Maybe tomorrow. The thing is lying in a drawer collecting dust right now. It's in fully working condition so I just have to dig out a CPU, some RAM and a display adapter (I'll find all of that in my basement. you won't believe how much computer crap 'I have :D )

Ok, here's the BIOS ID for the pentium mobo:

51-0300-428021-00101111-101094-TRITON-H




Intel Triton. w00t :D
