Well, I'll leave that part to the more experienced people, I can make a guess, but if you use this and it goes to hell, I want you to know, that you took the responsibility of using _my_ script..
hiddenmenu
title Fedora Core (2.6.9-1.681_FC3)
root (hd0,0)
kernel /vmlinuz-2.6.9-1.681_FC3 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.9-1.681_FC3.img
-------------------------------------------------------------------------------------------
Right, this top part specifies the Fedora selection of the menu, so
what we need to do is to get the same information from the SuSe
and apply it in the snippet below.
-------------------------------------------------------------------------------------------
title SuSe Prof (kernel_name_here(I think))
root (hd0,0)
kernel /vmlinuz-2.6.9-1.678_FC3 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.9-1.678_FC3.img
Uhm, anyway, let's leave this to someone who actually know's it, neh?
