I'm trying to install RHAT 4.0 on an ML115 server (which has SATA Hard Disk) but it can not find the disk drive. How can I ovecome this issue ? I went to the HP site to download any possible Storage Controller drivers needed. After I download the rpm driver (cpq_cciss-2.6.18-10.rhel4.x86_64.rpm) what are the steps to install the driver on the server ?
