Unlocked BIOS for the ProBook 430 G1, with the HP option code C8Y10AV in the name, provided as a 3.60 MB rar. Unlocked typically means the BIOS password or similar security lock has been removed from the image. Write it to the SPI flash with a clip and programmer to free a locked laptop. The name gives no board number, so check the PCB code first, and save the original dump beforehand because it holds serial and product data specific to that machine.
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 @biosfilebins. Enginerys does not host this file.
