Description
A BIOS dump file, 8 MB in size, stored as a BIN image and labeled for an 8 MB flash chip. The original file name is 4540s.bin. The facts do not name the brand, model or board number, so confirm the source before using it. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Read and save the original contents of your own chip first, and make sure the board number and revision match the target machine before writing anything.

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: 4540s. 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.
