Here is some info from my dual boot system. (it really is a quad boot
system) My box has two drives that are both set up to dual boot. I have
winXP and RH9 on hda and wixXP and FC 1.91 on hdc (I change the bios
boot order to switch drives for booting)
The FC 1.91 install was done by installing FC 1 and yum updating the
rest to current /develpment. This info may not be as helpful as if I had
installed FC 2 test 2 but if may be useful for reference since I can
boot into any of the 4 installed systems. I have grub in both MBR but
only boot into the 2 systems on the drive I am booting from.
hope this helps,

here is the output from parted print:

Warning: Unable to align partition properly. This probably means that
another
partitioning tool generated an incorrect partition table, because it
didn't havethe correct BIOS geometry. It is safe to ignore,but ignoring
may cause
(fixable) problems with some boot loaders.
