BIOS firmware for the Toshiba Satellite C660 built on the Compal LA-6842P mainboard, a RAR archive of about 2 MB. LA-xxxxP is Compal's board-numbering pattern, and Compal manufactured this board for Toshiba. The dump is meant to be written to the SPI flash with a programmer when the board does not start or the BIOS is corrupted. Read and keep the original chip contents first, confirm that the image size matches the flash chip, and check that the board number on the PCB is LA-6842P.

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 →
