Your BIOS needs to support booting from your USB device. Otherwise, you
will need to bootstrap off of another BIOS bootable media.

This is a motherboard BIOS limitation. You can always boot your USB
kernel from floppy and continue using the USB device for your rootfs.

Some Phoenix BIOSes (particularly laptops) have USB bootable floppy
support, which is simply a standard usb-storage device. Unfortunately,
they don't seem to permit booting from a USB Pen drive (I've tried to do
this on my VAIO to no avail).
