BIOS image set for the Fujitsu LIFEBOOK U748, identified by the board code CP768805-Z1, in a 7.80 MB RAR. Use it to restore a laptop whose flash is corrupted, by writing the dump to the SPI chip with a programmer such as a CH341A and a clip. Before writing, save a backup of the existing chip, which may hold unique serials or configuration data. Confirm that the CP number on the mainboard matches, and that the image size fits the installed flash chip.
