One of my systems has an IDE disk and a SCSI disk. I upgraded the IDE disk

I've tried various things to install GRUB on the new /dev/hda, but everything
results in a complaint during boot that
Error 21: Selected disk does not exist.
For example, in GRUB shell, I installed using:
> root (hd1,0)
> setup (hd0)
The installation seems to work fine, but boot fails as above. I had this
working before, but for my life I can't recall how I did it differently from
this.
What am I missing?
Thanks.
Apparently, the machine was having some trouble detecting the IDE drive as
a boot device, so it was skipping ahead to try and boot off the SCSI one.
This is a very old machine (my first Linux machine ever, a P-166 that
originally ran Red Hat Linux 3.0.3) doing print and backup service in my
closet) and it doesn't seem to like the new very large disks much.
Ah, well, it's quite a senior citizen in computer years, and it kept up
well. It's running FC4 pretty happily (no GUI though), but it doesn't
have enough memory to install FC5.
