Eric,

When I tried setup (hd1) grub barfed. Anyway, I ran Knoppix and performed a grub-install and all is good with the world now. I can boot the machine with no problems.

Many thanks to everyone who chipped in with suggestions. It has been fun......err sort of. Anyway, to recap what to do in the future:

1. Move the drives around any which way you please. Add drives, remove drives, whatever.
2. boot with KNoppix
3. Knoppix will find your boot partition, or use fdisk -l.
4. mount the boot partition rw
5. run grub-install
6. reboot.

Thanks to all again!

Mark

setup installed grub on a partition, not the mbr of the drive. You
should have "setup(hd1)" to make it update the mbr of the drive.

You should be able to redo this from just about any live cd. Just make
sure you use the proper values for the configuration as it is currently
running.
