BIOS Boot Sequence Security

Recently I needed to boot from a Linux CD for Imaging (Zenworks).  When the computer finished booting the hard drive was not showing!  This was because there is now a SATA controller (even though it did not show as a SATA controller).  The module in the Linux kernel for SATA controller is usually disabled; it has been flaky in the past.

But that is not the problem (that one’s solved), actually this got me to thinking about security.  We used to be able to set the boot sequence and Admin password in the BIOS to prevent hackers from booting from a foreign boot disk.  But now with the F12 option, I can no longer do so.  My suggestion is to add a BIOS option that if Admin password is enabled that the hard drive is not available with a F12 boot.  Of course, this option should be allowed Enable/Disable with the Admin password access.

Has this been suggested before?  What do you think?
