BIOS lock password
Boot loader (e.g. GRUB) password
Of course the boot off knoppix (similar) can never be blocked.
Yes it can, if the BIOS boot sequence is not changeable (i.e. BIOS password
protected) or, better still, the CD-ROM drive and floppy are removed.
Of course, give me physical access and I can get past most things - but if
the chassis is locked, I'm pretty much stopped in my tracks as I can't get
access to the mobo battery to reset the BIOS password.
