Description

BIOS dump for the Compal-built laptop board NM-A901, platform CYG50, supplied as a BIN file of 8 MB for an 8 MB flash chip. The original file name references a Yoga 910-13IK, so the dump appears to be aimed at that laptop, though the board number is the key identifier to match. Technicians use a dump like this to reprogram the SPI flash with a programmer after BIOS corruption 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.

For board NM-A901 the catalog also has 1 schematic, 1 boardview file, and 3 BIOS dumps.

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: CYG50 NM-A901. 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.
