Triple Boot issue

Hello All,

I am trying to Triple boot a system. One hard drive with three partitions. Partition one has Win2K, partition two has Fedora Core7.0, and partition three has open SuSe 10.3. I am using GRUB boot loader, bot I am unable to get both Linux distros to boot off the boot loader. When I use the GRUB loader that came with the Fedora distro, I can boot Win2K and Fedora, but not Suse. When I use the SuSe GRUB loader, I can boot Win2k and SuSe. I have tried to manually add the Fedora to the SuSe GRUB loader to no avail, and I have tried to add the SuSe to the Fedora GRUB boot loader. It seems to me that this should be a straight forward fix. Although both distros are using GRUB, the settings for GRUB in each distro is different. As follows:

SuSe GRUB configuration:

root (hd0,2)
kernel /boot/vmlinuz-2.6.22.5-31-default root=/dev/disk/bu-id/scsi-SATA_ST3250310AS_5RY0Q373-part3 vga=0x31a splash=silent showopts
initrd /boot/initrd-2.6.22.5-31-default

Fedora GRUB configuration:

root (hd0,1)
kernel /boot/xen.qz-2.6.20-2925.9.fc7
module /boot/vmlinuz-2.6.20-2925.9.fc7xen ro root=LABEL=/ rhgb quiet
module /boot/initrd-2.6.20-2925.9.fc7xen.img

When I try to replicate the configurations in the others configuration, GRUB says that there is an unknown command. Anyone have any advice out there?

Thanks in advance!!
