[CentOS] Centos 5 and Driver Disks

Hi,

I am trying to install CentOS 5.2 on a Dell PowerEdge R905, and a 
problem that you run into is that the DVD Drive on the system is not 
recognized by the kernel.
I have done some searching on the web and found 
http://kbase.redhat.com/faq/FAQ_103_13121.shtm and obtained the driver 
disk that it mentions. 
Having followed the instructions I can see and select the driver disk 
image but the install thinks there are no appropriate drivers in the image.

Can someone please confirm or deny that I should be able to use a Red 
Hat Enterprise Linux 5 Driver with CentOS 5 without issue ?

It isn't a big deal as I will try a Network based install or use a USB 
DVD drive but I just want to confirm if using a RHEL 5 Driver Disk 
should work :)

Thanks, and have a nice day
