I have a pair of HP DC7700 's that I'm about to deploy to a computer lab here. Because it's a public lab situation I'd like to prevent users from entering the BIOS. This works fine on one of the machines, but the other won't accept a password. It allows me to enter the password and save and exit the BIOS, but on reboot does not enforce the password I just created.
I've tried restoring factory defaults first, but that didn't help.
