FIRST, BACKUP ALL YOUR DATA

Make sure you have unallocated disk space on which to create partitions 
for the new OS installs.  You will need a minimum (for a minimal text 
only install) of about 1.5GB per OS.

But you probably want about 6GB (or more) per OS for a standard GUI 
desktop install to play around with.  If you want to install LOTS of 
stuff, you may need 10GB or more per OS just for the install.  And if 
you are going to put pictures and music and games and stuff on there, 
then you will want several more GB.

You may need to resize the existing RHEL4 partitions on the disk (or add 
more disk) to ensure you have  empty space for the new OS installs

You can only resize your partitions if you have unused disk space.

To see your disks and the partitions use "fdisk -l"
To see the amount of each partition that is being used by RHEL4
use the command "df -h" while running RHEL4

You can resize partitions with a bootable KNOPPIX live CD:

(YOU DID DO A BACKUP RIGHT?)

install the new OS's by booting from the CD/DVD install media and make 
sure that you create new partitions in the empty space you now have. 
(*do not* overwrite/reformat existing partitions used by your RHEL4 
install).

I am fairly sure that SUSE10 and FC6 will setup the GRUB boot loader 
with autodetection of the other bootable root's and when you are done 
you will be able to boot the system, hit esc' when the flash screen 
comes up, and select which OS you want from a menu.
