Tested BIOS for an ASUS board labelled A4321 revision 1.3, provided in a 10.4 MB RAR archive. The name gives no laptop model or chip size, so identify the matching unit by the board code and revision on the PCB. Dumps like this are used to restore a corrupted SPI flash with a programmer when a machine powers on but shows no image. Save the original chip contents before writing, as they hold serial and system data. Also make sure the image size equals the chip capacity.
