BIOS dump for the ASUS B34Y board, revision 2.0, intended for a Winbond 25Q64FV SPI flash, an 8 MB chip, packed in RAR at about 3.25 MB. Write it with a programmer such as a CH341A after reading and saving the original chip contents. Check that the extracted image is exactly the chip capacity, because an image of the wrong size will not fit. Confirm that the PCB carries revision 2.0, as earlier revisions may need different firmware.
