BIOS firmware for the HP 645 G1 notebook, supplied as a 2.99 MB ZIP archive. The name gives no board number, revision or version, so look at the contents and identify the motherboard before use. A dump like this is typically written to the SPI flash with a hardware programmer to recover a unit that powers on without display or has a corrupted BIOS. Back up the original chip first, check the board number on the PCB, and make sure the image size equals the flash capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
