Description
toshiba b551/c / satelite pro s750 tested The BIOS dump for the Toshiba B551/C laptop comes as a BIN file named B551C FHRLSY1 OK.BIN, sized for a 4 MB SPI flash chip. The uploader marked it as tested, though the catalog cannot confirm that claim. Technicians use a dump like this to reprogram the flash with a programmer after a corrupted BIOS or a failed update. Before writing anything, check that the board number and revision on your motherboard match the target, and save a full read of the original chip contents as a backup.

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 B551/C. 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.
