Description
ACER 3820 3820ZG_JM31-CP (09921-3 4HL01) (FIXED ME) bios & EC BIOS dump for the Acer 3820 laptop on the Wistron 09921-3 board (platform JM31-CP), packaged as a ZIP of about 1.9 MB that includes EC/KBC firmware alongside the BIOS. The original file name notes a "FIXED ME" variant, which points to a corrected Intel ME region. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS 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 09921-3 the catalog also has 1 schematic 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: Acer 3820 JM31-CP 09921-3. 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.
