Thanks for the input. Got it going, tried again the easy way and it worked this time. Think perhaps there may be a bad sector on the floppy I was using, can't think of anything else it could have been...
What I did was create a boot disk, shut the system down, swap out the old HD with the ghosted one, then botted using the floppy. Then just ran lilo, and away it went...
First time I tried that resolution, it didn't want to boot from the floppy. Second time it did. Go figure.
Anyways, it's fixed now. For my next trick, I'm going to see if I can get software raid going, as RH 7 doesn't like my Promise card....
