[Bootable USB drive ... ON a BIOS that doesnt support it]

Any Ideas huh? huh? I want to run Fedora on a USB drive but I can't get my mobo to boot from USB and I've checked BIOS updates and one that supports USB bootable devices dont exist... Atleast not from the manufacturer. If you have any Ideas let me know or a Hacked bios website Dhanke.
