Original BIOS dump for a Toshiba Satellite C800 series laptop, 4.00 MB in size, suited to a 32 Mbit SPI flash. The name marks it as an original read but gives no motherboard number or revision, so check the PCB label against the source before writing. It is used to reprogram the flash chip with a hardware programmer when the system fails to post. Save the existing chip contents before flashing and verify the image size matches the chip capacity.
