Description

From the original post:
EC ROM MEC5085 LA-971P (ok)

This BIOS dump is an EC ROM image for the LA-971P board, with the file name pointing to a MEC5085 embedded controller. The archive is a small RAR of about 0.2 MB and is marked as including EC/KBC firmware, so it is the embedded controller code rather than the main BIOS. Technicians use this kind of image to reflash the EC after corruption or a failed update, typically with a suitable programmer. The file name notes the image as "ok", but the facts give no further detail on the revision or tested status.

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: EC ROM MEC5085 LA-971P. 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.
