 OK, so the quest for a bootable file continues. The grub docs show the
following to make a bootable floppy;

[root at doozer grub]# dd if=stage1 of=/dev/fd0 bs=512 count=1
1+0 records in
1+0 records out
[root at doozer grub]# dd if=stage2 of=/dev/fd0 bs=512 count=1 seek=1
1+0 records in
1+0 records out

 To make a bootable disc. Now, if I want to use a file, instead of a
floppy, it would be the same. However, I also have a partition table.
Isn't that at the second block on a disc ? Wouldn't I wipe it by doing
that ?
