Thank you for your explanation .Can you suggest me an SPI programmer model to rip the Original bios ?
another Question why do I need to rip the original bios ? you can send me your modified one as you have already the same motherboard as me then I will program it into the flash chip with an SPI ?
excuse me ,my bad every motherboard has its own details (Mac address, serial number ...) that's why you asked me to send you the extracted bios.I hope you can make a guide on how I can do this modification by myself I have all the tools needed (UEFItool, MMtool).
hope you can post the method.
thank you again for your great help.
