[CentOS] CentOS 5 Beta Dual Boot Problem

To test CentOS 5, I loaded from DVD adding it to
a system at home running Fedora Core 7 T2.

Partition Layout is:
/dev/hda1   -  / for the RH7T2 system
/dev/hda2   -  /home
/dev/hda3   -  swap
/dev/hda4   -  extended
   /dev/hda5 - / for CentOS 5

The system loaded cleanly and gave me the 
opportunity to tell grub about the other system.
CentOS boots fine.  Grub Stage 2 will show me 
both systems.

However,
If I choose the FC7T2 system I get the following output:
---------------------------------------------------------
Booting 'FC7T2'  

rootnoverify(hd0,0)
chainloader +1

Error 13: Invalid or unsupported executable format
---------------------------------------------------------
The CentOS grub.conf on /dev/hda5 looks like:

#: cat /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this
file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,4)
#          kernel /boot/vmlinuz-version ro root=/dev/hda5
#          initrd /boot/initrd-version.img
#boot=/dev/hda

---------------------------------------------------------
Any clues on how to fix this?
Note, I am posting to both groups since I follow both
and cannot figure out which is the better choice.
