problem in the of installation rock cluster

Hai,
I am trying to install rock4.3 in my Intel core2 quad process, but when i insert kernel cd which is the first step in the installation procedure, it asks for driver disk not found.. insert CD/DVD ROM even after i inserted my CD in my driver.. could anyone help me in solving this problem...
regards
sasi

I'm not sure, but I think this is for OPTIONAL drivers. Your CD/DVD ROM device is called a "drive". The software that interfaces this device is called a "driver". Maybe that will clear things up.
