Judging by the lay-out of the board it was made by/for Intel.
Are there any markings on the board or on the stickers. The orange and white sticker on the bottom of the picture might have a clue.

Could be a Siemens, but we need some better pictures. Cannot read all the text on it.
Can you post a "POST"-screen.

I used to have an Intel Plato motherboard that looked very similar to this one, so my bet is on Intel as well.
Try this:

Board on page 32 looks almost exactly the same.
