Description
A BIOS dump stored as a BIN file, rated for a 4 MB flash chip, with the original file name U53 4mb-OK.bin. The facts do not name a brand, model or board number, so confirm the target machine before using it. Technicians use a dump like this to reprogram the SPI flash with a programmer after BIOS corruption or a failed update. Read and back up the contents of your own chip first, and make sure the board and revision match the dump before writing anything, since this page gives no further detail to confirm compatibility.

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: U53 4mb. 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.
