You may also have to use the map command to change the BIOS numbers of the drive.

Did you remember to include the high level SCSI drivers? Remember, USB disks are treated like SCSI drives, not IDE drives. But I don't know the driver manes for FC4 off the top of my head. >> >> Have you edited /etc/fstab to reflect that you are using a separate >> drive? > Yes. But right now the error is with the init.

Also, if your BIOS can not access the USB drive, then you can not boot from it at all. You have to have the /boot partition on a partition that is readable by the BIOS. But it looks like you are loading the kernel and initrd. You just don't have everything you need in the initrd.
