All right; since CentOS does connect, I can ssh to it; doing that, I get
the following on the p2 machine : 

[root localhost ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      18803436   3530836  14317416  20% /
/dev/hda1               101086     12455     83412  13% /boot
none                    192944         0    192944   0% /dev/shm
[root localhost ~]# 

If I'm not totally fouled up (yet), that tells me I do have a boot
partition on hda, and it's at hda1. Right so far?

Then I can edit /etc/grub.conf on the p2, go to the bottom of the file,
delete the rootnoverify and chainload lines, copy & paste your stanza
above onto it (with fc5 replaced by fc6) -- or maybe an fc6 stanza from
/etc/grub.conf on one of my own other machines, which would also get an
fc6 kernel version -- and then what?? Do I just leave what shows as
hd(0,0) still hd(0,0)??

Fwiw, here're a couple fedora stanzas from /etc/grub.conf on the machine
I'm using at the moment :

title Fedora Core (2.6.19-1.2895.fc6xen)
        root (hd0,0)
        kernel /xen.gz-2.6.19-1.2895.fc6
        module /vmlinuz-2.6.19-1.2895.fc6xen ro root=/dev/VolGroup00/LogVol
00
        module /initrd-2.6.19-1.2895.fc6xen.img

title Fedora Core (2.6.19-1.2895.fc6)
        root (hd0,0)
        kernel /vmlinuz-2.6.19-1.2895.fc6 ro root=/dev/VolGroup00/LogVol00
        initrd /initrd-2.6.19-1.2895.fc6.img

title Fedora Core (2.6.18-1.2869.fc6)
        root (hd0,0)
        kernel /vmlinuz-2.6.18-1.2869.fc6 ro root=/dev/VolGroup00/LogVol00
        initrd /initrd-2.6.18-1.2869.fc6.img

Will it work if I just put that (without the xen stanza) verbatim onto the
bottom of the /etc/grub.conf that's in the p2 now? Will it find hdb by
itself?
