Thanks for the excellent suggestion, I should have RTFM. Alas however
invoking map has made no difference although you are clearly right since if I
remove the IDE drive I can get grub to boot the NT.  Maybe I'm not
understanding the map command (and this time I think I have RTFM). It doesn't
seem to do anything.  Shouldn't I expect to have to do a rootnoverify
(hd0,2) after doing the map (hd0) (hd1) ; map (hd1) (hd0) - in other words
shouldn't grub 'see' the effect of the drive swapping?
