After a try after try flashig this bios on the board I did jus desoldered it and tried to flash it with my minipro programmer but I found out that this Atmel ic isn't at the supported list (or dunno wich is). So after a little investion guessed that it would be a AT45BCM021 but I had no luck flashing it.
