post the contents of the bios chip even if it is corrupted..

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer
