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...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Yes sir i've done many times still no display and bong sound.

Thank you for your reply and repair of my dump. But still no display and BONG sound. Maybe has something wrong with the motherboard.
