This is not the Main BIOS chip, I think there should be another chip on your motherboard (16MB or 32MB).

Thanks for your answer.
Yes, there is one more winbond chip but it's BGA. Unfortunately do not have a BGA reader at this moment.

Thanks Osman!
I'll try as soon as I get 64mb BGA chip reader.

Sorry I was wrong the chip is SMD.
I'll find the right reader board to solder and let you know the result.

Thank you!
