Thanks Paul. Your help is much appreciated.  It's useful to know that 1.16 is the final update for non-AMT machines. I inadvertently applied  HP Compaq dc7700p Business Desktop System BIOS for Intel vPro Technology (786E1 BIOS) 3.05 sp44219 which has corrupted my BIOS. I have tried unsuccessfully to load various BOOT CD bins on USB without success so far. Incidentally sp38915 turns out to be for a 2026 product and is a a red herring. Co-Pilot is telling me that in Emergency BIOS Recovery Mode for my machine, I have to load RAW binary file which is no longer included in the BIOS versions now available. I will keep trying but not for much longer.

You're very welcome.

Actually that sp38915 file is for some kind of display from 2007.

I explored the driver setup file.

Using the HP Compaq Business Desktop System BIOS (786E1 BIOS) 1.16 file, you can make a  CD recovery file with it.

I've attached the readme instructions and the ISO image you can burn to a CD to make the recovery file.

I've also attached the DOS flash files if you want to try and recover the BIOS that way.
