BIOS dump for the HP Compaq Presario CQ61-405AX, stored as a 1.81 MB ZIP. The name gives only the model, with no board number or revision, so verify the mainboard code on the PCB before flashing, since this series used both AMD and Intel boards. Such images are programmed into the SPI flash with a hardware programmer to revive a laptop stuck on a black screen or failing POST. Back up the original chip, confirm the image length equals the chip size, and check the board match carefully.
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 @Laptopdesktopbios. Enginerys does not host this file.
