BIOS archive for a Toshiba Satellite L850-1JG, part number PSKG8E, packed as a 2.89 MB RAR. The PSK prefix follows the Toshiba part numbering used on its Satellite models, and the name gives no board number, chip type or version. Repairers use such a dump to reprogram the SPI flash of a laptop with corrupted firmware or a forgotten BIOS password. Check the board number on the PCB, confirm the image size matches the chip, and read the original contents to a backup before writing.
