Err, there is a mistake here somewhere. If you are getting 1FA at the
prompt then lilo is *NOT* in the MBR. If it were you would get the lilo
If lilo is not installed in the MBR it still replaces the default MBR
another one to allow you to boot to either the DOS partition or lilo.
BTW, the reason you cite above is exactly the reason I always install
lilo in the MBR and and on another partition.

OTOH, if you have physical access to the machine is there really any
