bootable CD-ROM image to memstick image?

[Ian Smith]

I have a bootable BIOS/EC update CD image for a Lenovo X200, with no CD.

It contains the same good ol' DOS 6.0 BIOS update program as ever, after 
a loader from not so good ol' Nero Burning ROM, after 64KB of zeroes.

root at x200:~smithi/biosupdate # file 6duj48us.iso
6duj48us.iso: # ISO 9660 CD-ROM filesystem data '6DUJ48US                        
' (bootable)
root at x200:~smithi/biosupdate # mdconfig -f 6duj48us.iso
md0
root at x200:~smithi/biosupdate # mount_cd9660 /dev/md0 /mnt
root at x200:~smithi/biosupdate # ls -a /mnt
.       ..
root at x200:~smithi/biosupdate #

Is there a generic way to convert this into a bootable USB image?

cheers, Ian
