USB booting :: USB-Booting via Lilo

I have a laptop with a bootable CD drive and i have installed linux to a harddrive partition. During the install i have my flash disk in and recognized as sda1. Anyways the installation finished and it started the lilo install. That worked fine. Now when i boot i get three options:

Linux
Windows/Dos (sda1)
Windows (hda5)

Now the question is can i simply use lilo to tell the computer to boot from the USB drive? Basicly have Lilo act as a workaround for outdated computer bioses. I will try it at home and see what happens.

Please post information on anything that you think i might need to know (this is my first usb boot attempt).
