Locate BIOS chip on Fujitsu D2156-S21 GS3 motherboard

[Askic]

Hello,

I have a Fujitsu motherboard D2156 that cannot post. So I suspect that BIOS became corrupted. However, I'm not able to locate a chip on the motherboard that could be the BIOS. The pictures are shown in the attachment. I have no idea where BIOS is located. Recently I have reprogrammed BIOS chip on Asus motherboard and it was 8 legs chip from Winbond.

However this Fujitsu board is pretty different.
Any help would be highly appreciated.

Thank you!

Thank you. I suspect this could be it. It is written on it ATMEL0729, 26F004, but there is also one more chip that has also ATMELxxx on it.
Is it possible it has two?

Here are more detailed pictures.
The problem is that I cannot find a single, unique 8 legs chip on the board.

226F004 sounds like it could be a BIOS chip
