In reality, I tried to boot from either hda1 or hdb1 for my systems. I
haven't tried to boot from a primary partition hda2 or higher.

I did have a problem with getting xp to boot from a system where grub
was installed in the mbr of the primary ide drive and /boot was
installed on /hdb1. XP would not boot without adding makeactive in the
chainloader command for the XP entry.

I'll mess around with combinations of installing grub in different
primary partitions on one of my drives and see what happens with the "in
theory", put into have tested for hda2 and higher drives.

Unless you have the above 1024 cylinder problem, I don't know why it
didn't work as assumed.
