Booting USB keydrive from BIOS

[Pedro M.]

 I tried to boot JetFlash ( http://www.transcendusa.com )  with Flonix (
http://www.wikipedia.org/wiki/flonix ), but something is wrong, because I only can boot it
using a floppy. 

I  have USB boot support in the BIOS. 

What can I do to boot the keydrive (http://www.wikipedia.org/wiki/keydrive ) with Flonix
???? 

Thanks in advance. 

( I think sell bootable USB keydrives with Flonix pre-installed would be a great
idea....).
