Have done that, thanks for the reminder! However, that didn't result in XP or 
fc17 being detected. Is there some magic I can do to tell grub2 to actually use 
the fc17 boot and root, or am I screwed? The XP is less of an issue, I only use 
it to check that websites are viewable with IE, and I can just boot it under KVM 
and run it in a VM.

I avoid editing the grub.cfg file for three reasons:
   1 - I don't know what I'm doing, if magic is needed the install/upgrade
       should be the magician. The average users knows way less than I do
       about system setup.
   2 - The last time I did the system wound up being a totally unbootable
       recovery adventure. See #1
   3 - every kernel upgrade seems to rebuild the config file, making
       change a brief success.

All suggestions appreciated.
