BIOS firmware image for the HP Compaq Presario CQ42-402AU, a model the name tags as an AMD VISION platform machine. The dump is 2.00 MB, which corresponds to a 16 Mbit SPI flash chip. Technicians use such an image to recover a board that powers on with no display or is stuck after a failed update, writing it with a programmer such as a CH341A or RT809. Read and save the original chip contents first, confirm the chip capacity matches the file size, and check the board number printed on the PCB before flashing.
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 @bios_laptop. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
