ASUS K55VD notebook BIOS for board revision 3.1, marked in the name as tested OK, which suggests it was confirmed working on a real board. The 8.00 MB size suits a 64 Mbit SPI flash chip. Technicians program it directly to the chip to recover from a corrupted BIOS or a no-boot fault. Check that the motherboard is the K55VD at revision 3.1 before use. Keep a copy of the original chip so any serial number or MAC data can be carried over.
