Yes, that is what I was meaning - drop it altogether ...

Wierd, so you can mount it etc ...? strange ... does
'cat partboot.img >/dev/null' report any error? I just did a
'dd if=partboot-1.2.11.img of=/dev/fd0' on my Debian box and it worked
fine ... Unless the disk you're trying to write it to has errors on it
or something ...
