Tested BIOS for the ASUS X540MA motherboard revision 2.0, intended for the dual-core CPU variant, stored in a rar archive. Since the X540MA came with different processors, the CPU note helps match the image to the board in hand. Technicians flash such a dump to the SPI chip with a programmer to revive a unit stuck on a black screen or a boot loop. Check the revision on the PCB, back up the original chip first, and make sure the image size matches the chip before writing.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
