BIOS dump for the Toshiba Satellite P855-S5312 built on the Compal LA-8392P motherboard. This number differs from the LA-8391P by one digit, which usually marks a separate board variant, so do not swap images between them. The 3.19 MB RAR is used to recover a dead or locked BIOS by writing the SPI flash chip with an external programmer. Confirm the code printed on the PCB, save a full read of the original chip, and check that the image size fits it.
