Description

BIOS dump for a laptop board numbered NM-B701, platform EY520, produced by Compal. The original archive name refers to a Legion Y7000 2019 with board numbers EY515, EY517, EY519, EY520 and NM-B701, so the file may cover more than one configuration. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after corruption or a failed update. Before writing anything, confirm that the board number and revision on your motherboard match, and back up 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: EY520 NM-B701. 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.
