Original backup of the BIOS from an X55LD board, revision 3.3, likely an ASUS model, stored as an 8.00 MB raw binary. The 8 MB size corresponds to a 64 Mbit SPI flash chip and can be written directly with a programmer. Make sure your PCB shows the same revision, because the rev 2.0 and 3.3 boards may not share firmware. Since the dump comes from a working unit, serial and system data may need editing. Read the target chip first.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
