Yeh. I'm going into just for giggles mode now. See below.

Still can't get hold of floppies, as my supplier hasn't any. Disk drive is as
good as new (recently replaced), and I also tried all this stuff on the other
machine that had Debian running, with exactly the same results. I'll have to
try and find another source for the floppies.

I looked in the BIOS of the other machine, and the only boot options are
floppy, or harddrive.
I know what's going to happen here. The problem will be solved on the very day
that the new floppies arrive in the mail.
Unfortunately, I've only got a bike. Otherwise I could drive a few Miles, and
pick some up at a computer store.
Thanks for the help.
Nigel.
