Sure. If you hold down the shift key very soon in the boot cycle,
you'll get a prompt like "1FA:", which is mbr's friendly way of saying
"You, pick Partition 1, Floppy, or Automatic" as the boot process. (Of
course, this prompt may look a little different depending on how you've
configured your system). It is the default master boot record installed
by Debian (unless you choose to NOT install a master boot record; most
users do, I imagine), and it will allow someone to boot with a floppy
before LILO even runs, unless the sysadmin has disabled floppy boot in
BIOS. Not all BIOSes support this option, so it makes sense to consider
mbr's place in a security scheme.
