Hi Tim. My confusion was in not realising that Grub counted the harddrives
sequentially, ignoring how they were identified in /dev. This wasn't helped
by the fact that /dev/hda, and /dev/hdb, the first 2 harddrives, were listed
by Grub as (hd0), and (hd1), which at the time seemed to confirm that Grub
followed the listings in /dev. Logically then /dev/hde is (hd4) right? No.
Very wrong, and resulted in the long running argument with Grub, with it
constantly saying "no such disc" when I tried install Grub in (hd4).
Anyway I've learnt a bit more about Grub along the way. One thing is not to
argue with it. You can't win.
Thanks for the reply. Nigel.
btw. Did you see the post I sent back with regard to your question. "How do
you know which cards are capable of multiple audio streams before you buy
them?" The thread is "Audigy 2 has no playback sound"
