Description

BIOS dump for a laptop motherboard with board number 12243-3, platform EA40-HW, built by Wistron, supplied for an 8 MB flash chip. The original file name points to an MX25L6473 chip, so the dump matches that SPI part. Technicians use a dump like this to reprogram the flash with a programmer after a corrupted BIOS or a failed update. Before flashing, confirm that the board number and revision on your motherboard match the file, and save a backup of the original chip contents so you can recover if something goes wrong.

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: EA40-HW 12243-3. 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.
