Booting to CD and the handing off to HD

Thanks for the response!

I would like to have it completely automated:

The machine goes down at 4am for the check and boots to cd, then the cd
controls the hand-off to the hard drive.  I'd like to have the BIOS
setup to only boot the cd and if the HD checks out ok, boot up the HD. 
That way there is a slim chance that any security breach will last
beyond one night on my machine.  I seriously doubt a security breach
will occur, but I want to close every door imaginable.

Anything else that could be done?
