Are you sure about that Fergal? IIRC there is some unused space at the
start of the CD that has been co-opted for the el-torito bootable bit. I
know Adaptec Easy CD Creator generates 2 files on the CD but there's a bit
more magic than that involved. For example, I don't think it's possible to
copy the bootable bit onto a floppy (or even rawrite | dd it) which you'ld
need to make a bootable copy of the disk unless you use a RAW copy (well,
not quite raw but a sector for sector or block for block copy) program.
