Go to the HP.com website and download the SmartStart CD for your system. This has everything you need to configure the raid. The raid on these machines is a 'hardware' raid running through a proprietary raid card. It is 'extremely' robust. However, you must use the HP SmartStart disk (or perhaps there is something else from hp/compaq?) to configure your raid. The raid card in that machine most likely has a battery on it to allow protected write caching. Very speedy. The battery is used in case of power outage... the data still gets written. As for the OS selection, don't worry about it, just create the raid and CentOS will find it and install.
