Description
BIOS dump for an HP laptop with a 4 MB flash chip, supplied as a BIN file. The original file name is Compaq CQ 42-303TU Main.bin, so the dump is tied to the Compaq CQ 42-303TU model line. Technicians use a dump like this to reprogram the SPI flash 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 model the dump was taken from, and read and save the original chip contents as a backup first.

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: HP Compaq CQ 42-303TU Main. Dumps from a different board or revision can leave the board dead.

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.
