See "man lilo.conf"
% password=password
% Protect the image by a password.
% restricted
% A password is only required to boot the image if
% parameters are specified on the command line (e.g.
% single).
The above allows you to lock out "linux single".
If you can also set the BIOS to boot only from HD, password protect the BIOS,
and put an anti-tamper microswitch on the case, you should be fairly safe.
If not, please let me know !!
