Description

From the original post:
JT4B1 JX3B0 NM-E091 REV 1.0 TESTED 64MB

BIOS dump for a laptop with board number NM-E091, platform JX3B0, from the ODM Compal, PCB revision 1.0. The uploader marked it as tested, but that is their own note and has not been checked by us. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Before flashing, confirm that the board number and revision on your motherboard match the file, and read and save the original chip contents as a backup. The archive is a RAR file of about 77 MB.

For board NM-E091 the catalog also has 2 schematics and 2 boardview files.

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: JX3B0 NM-E091. 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.
