Description
BIOS dump for the Lenovo laptop built on the Compal LA-E291P board, supplied as a RAR archive of about 6.1 MB and including EC/KBC firmware. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update, and the bundled EC/KBC firmware covers the embedded controller as well. Confirm that the board number LA-E291P and its revision match your motherboard before flashing, and save a backup of the original chip contents first.

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 LA-E291P. 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.
