You are using a VERY old and unsupported version of RH http://www.server-world.info
called RH9 (Shrike).
The new version is called RHEL (note the E = Enterprise) and is only up to v6.3.
NB: you would have to pay to use this, so I recommend Centos instead: a free rebuild of RHEL.
The old RH series will not support current HW.
