Interestingly, I just tried manually mounting the disk:
mount /dev/sda1 /mnt/sysimage
and I can get a directory listing. So at least *part* of this is
working. From there, I was manually able to run 'chroot /mnt/sysimage'
without error, and it seems to have "taken". However, trying to run
grub-install gave me:
/dev/sda: Not found or not a block device
Running the second option (--no-floppy --recheck) gave me:
Probing devices to guess BIOS drives. This may take a long time
No suitable drive was found in the generated device map.
Reverting to backed up copy.

Done - no problem. There's /, /home, and swap.

Running fsck.ext3 *says* that the partitions are clean. If I need to, I
guess I could get the data off of the drive and install on another, but
I was hoping to avoid that. Feh...
Thanks for your help,
