Thanks! I got the extracted file and renamed it as AMIBOOT.rom. Put in a blank usb pen drive, plug to the usb port( tried both), pressed CTRL+HOME (with a FN key), but seems no read to the usb pen disk(the LED is not flashing). anything I did wrong?
I've tried from the bios (not from DOS). Is there a difference? Do you know why It brick my board? Btw ,don't worry, I've recovered the original bios with Afude 561.exe
