RH 9.0 is very old and making it work would be quite difficult.
I would strongly urge you to consider installing Fedore Core 4 ( RedHat's replacement ).http://mirrors.kernel.org/fedora/core/4/i386/iso/FC4-i386-DVD.iso
The DVD is much more convenient however if you do not have a DVD recorder you will have to use the CD set:http://mirrors.kernel.org/fedora/core/4/i386/iso/
You do not need the SRPM disks just the installation and rescue CDs.
Good Luck! :-D
