BIOS firmware for the HP 280 desktop, motherboard FX-ISL-2 at revision 1.00, packed in a RAR archive of about 4 MB. The name does not state the flash capacity, so compare the extracted image with the SPI chip on the board before writing. Technicians use such a dump to recover a unit that will not POST, or to replace firmware damaged by a failed update, by flashing it with a hardware programmer. Save a full read of the original chip first, since it holds board-specific data such as serial numbers.
