Description

BIOS dump for the Toshiba S55 laptop, revision 2.1, supplied for both 2 MB and 1 MB flash chips and marked as tested by the uploader. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after BIOS corruption or a failed update. Before flashing, confirm that the board number and revision match your machine, and back up the original chip contents so you can recover if the write goes wrong. The uploader's tested mark is their own claim and has not been independently verified.

Questions about this file

How do I flash this BIOS dump?

Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.

Will this BIOS work on my board?

Only if the board number and revision match: Toshiba S55. Dumps from a different board or revision can leave the board dead.

What does “clean ME” mean?

The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
