Description
BIOS dump for an HP laptop, supplied as a ZIP archive of about 1.1 MB under the original file name CQ20_cq2230_GM45 493185-001-hp.zip. The name suggests the CQ20 / cq2230 family and a GM45 chipset reference, but no board number or revision is listed here, so confirm those against your own board first. A dump like this is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update.

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: CQ20 cq2230 GM45 493185-001-hp. 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.
