BIOS dump for a laptop built on the Compal NM-A311 board, shared as a RAR archive of about 2.4 MB under the original file name G50_30_a7cn48ww_64.rar. The Telegram caption lists the board as NM-A311, revision 1.0, with the markings ACLU9/ACLU0. A dump like this is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Before writing anything, confirm that the board number and revision on your motherboard match, and save the original chip contents as a backup 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: NM-A311. 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.
