That helps, yes, thanks. But I have another problem,
possibly mine alone as a refugee from pure mathematics: I've
never been able to tell whether a device is hardware, or software
that does something with it -- identifies it, talks to it,
whatever. Sometimes it seems to be one, sometimes the other --
to the extent that one hardware browser seems to use an entirely
different language than another.

So when my tab did nothing, and I took a stab at
substituting (hd0,0) into Varol's directions, I got lucky, right?
Incidentally, that particular machine, designed as a
server, has two hard drives, which were originally locked
together to make one clone the other. I got my Friendly Local
Alpha Plus Technoid (FLAP) to unlock that. So would /dev/sdb have

I have never owned a television. Nor wanted to.
