Hi I have 2 A747c Pavilion Desktops which up until tonight had the factory BIOS 3.06 release. We went to the HP website and downloaded the updated 3.28 release. Ran BIOS update on machine A which went fine. Did the same on machine B and it did not take. Both machines are supposed to be identical & were purchased at the same time. Contacted HP Support and they said that I need to locate the original 3.06 BIOS which is a file called HPBIOS.ROM file to allow the BIOS recovery which the machine is attempting to perform to complete. Can anyone help me secure the 3.06 BIOS so I can reflash the system to its original state? Thanks Drew :)
