Description
BIOS dump for a laptop on the Wistron 18458-1 board, distributed as a 13.9 MB RAR archive. The uploader marked it as tested, but that label comes from the poster and has not been independently checked. Technicians use a BIOS dump like this to reprogram the SPI flash chip 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 read and save the original chip contents as a backup so you can restore them if something goes wrong.
The catalog also lists 1 BIOS dump for board 18458-1.

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: 18458-1. 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.
