Firmware archive for the Toshiba Qosmio X305, about 1 MB in RAR format, with no board number or version listed in its name. A dump of this kind is used to restore the BIOS chip on a laptop stuck without POST or with a blank screen after a failed flash. Unpack it and confirm the image size corresponds to the flash chip fitted on the board. Identify the motherboard number from the PCB, read and save the original chip before programming, and verify the write with a compare pass afterwards.
