How to add an existing linux on a newly added disk to grub ?
 

I have a RH 9 system dual booting with windows through grub.

I have a linux MEPIS on another drive that also boots through grub from another computer.

I want to add the MEPIS drive to my RH9 computer. How do I tell grub that MEPIS is there?
The MEPIS system also has grub on its MBR. Will that cause problems?

Thanks

edit "/boot/grub/menu.lst" and add a new section for your 2nd linux
