Tony, Thanks. After all my efforts to "fix grub", then move disks around failed. I finally had to resort to booting with Knoppix and doing a grub-install on the drive with the existing Linux distro which moved from hd1 to hd0. Should have done that in the beginning....switch the drives, run a Knoppix, grub-install, and be done with it. I am running Debian testing, and have grub 0.97 installed.
