Yes it is, all of it (or, all of it that I could withot going 'dangerously 
dedicated'). I have never had any intention of putting Windows on this disk. 
I think W98 just assumed it 'cos it was the primary master.

No. But Windows is runing quite happily on ad0 (or "c:\" :-)

No, the BIOS knows where the disks are, autodetects with no problem, and the 
defaults it offers match whats on the disk label (I mean the physical, paper 
label on the metal disk housing!) - and Windows is fine on the other disk - 
the problem is, really, that there shouldn't be a windows partition on _this_ 
disk at all.

80Gb, nominally.

If you say so! It knows more than me about disk geometry and so on, I guess.

But seriously, does any of this suggest a course of action to you? I'm 
planning to try the "set sysid to 0" plan... what if that doesn't work?

The fact is I really don't understand in any kind of detail how this stuff 
works - I'm just trying to ask the right questions...

Thanks a lot for taking the time to think about this, I appreciate it.

Cheers,
Ben
