BIOS archive for the Toshiba NB500 netbook, marked as OK in the name, in a 478 KB RAR. No board number or revision is given, so the PCB should be inspected to confirm which mainboard version is installed. Netbook firmware of this kind is usually written to a small SPI flash chip using an external programmer with a clip or after desoldering. Read and store the existing contents before erasing, verify the written data afterwards, and ensure the extracted image size equals the capacity of the chip.
