or in a lab-like environment:

 set to only boot from harddrive

 password protect the bios

 password protect lilo

 padlock the case closed (or put the case in a lockable steel cage)
 (*make sure people can't just poke the 5.25 cover off, and reach in
 anyway*)

 make sure that the machine boots to sulogin on single user
 (ie: failed fsck)

and then you should be reasonably safe. floppy / cdrom can be accessed
using the normal permissions (don't allow suid or devices on those
media tho..)
