HP DV7 Series BIOS and PCID

If you come across a corrupted BIOS or a bad flash of an HP DV4/5/6/7, you may see the error System Board (00A)

Usually you can fix it with the HP DMI Tools from HP (HPBQ138.exe) , but in some cases the PCID is not 25 chars but 17. This come with the error below…

The input PCID is invalid





The tools here are the old versions which allows to edit the DMI to 17 chars

P.S. You will need a MS/Free/Mini-DOS bootable USB disk, and then copy the files

to the flash drive.
