    Which hard drive and which partition is the boot partition? I only have one IDE drive on the second partition so (hd0,1) is the drive/partition that it resides on.

    You set it up wrong. It should look like this:

    Code:
    grub> root (hd5,0)
    You were telling it to install on the first partition of the first drive. Grub refers to hard drives in terms of numbers, starting with 0. So in your face /dev/hdf1 would be hd5,0.

    The format is (hdx,y), where X is the number that the BIOS has assigned to the drive and y is the partition number. Both of these are zero-based.
    The BIOS drive numbers often correspond to Linux's drive 'letters', ie. hda is hd0, hdb is hd1, and so on until hdf which is hd5.

    Actually, I think that the BIOS might skip the CD-ROMs in the drive numbering. What drives do you have installed on each bus?

    Then it probably is hd1, like you said. However, in your first post, you ran "root (hd0,0) /dev/hdf1". Try "root (hd1,0)" instead.
