Description
LENOVO_Thinkpad_E431 VILE1 NM-A043 Rev 1.0 SPI8M CLR ME REGION TESTED OK BIOS dump for the Lenovo ThinkPad E431 laptop, board NM-A043 revision 1.0, platform VILE1, made by Compal and supplied for an 8 MB SPI flash chip with the Intel ME region cleaned and marked as tested by the uploader. Technicians use a dump like this to reprogram the SPI chip with a programmer after a corrupted BIOS or a failed update. Confirm that the board number and revision on your motherboard match before flashing, and back up the original chip contents first, since a mismatched image can leave the laptop unable to boot.

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: Lenovo ThinkPad E431 VILE1 NM-A043. 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.
