Hello;
this is the way I boot XP/FC2/FC4T2.
They are all on seperate drives.
My system:
hda - WinBlow$ XP
hdb - FC2
hdc - DVD burner
hdd - FC4T2
Install XP first to hda
Install FC2 to hdb, make sure to create a /boot partition.
Remove the labels from the drives and change /etc/fstab to reflect
this.
(e2label /dev/hdx "" )
Of course XP/swap/extended have no labels.
Then added a small drive for FC4T2, installed to it using its mbr,
ignoring all other drives from disk druid.
Again it has a /boot partition, and again remove the drive labels
Now when I boot I get this grub:
Mount your old (FC2) and copy/paste grub.conf

This will probably line-wrap.
Hope this helps.
