Description

From the original post:
DELL STUDIO 1558 FM9C DAFM9CMB8C0 REV C PWB A00 WORKING BIOS & EC 100% TESTED OK U39 & U40

BIOS dump for the Dell Studio 1558 laptop, Quanta board DAFM9CMB8C0, revision C, delivered as a RAR archive of about 2.2 MB. The uploader marks it as tested and says it includes EC/KBC firmware, so the embedded controller image comes along with the BIOS. 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 match your board, and save the original chip contents first so you can restore them if needed.

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?

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.
