I have to install a driver for a sata raid controller. I have the choice between a version without args and a version X86_64. How can I tell what sort of server it is. I am installing a siemens econel200 SATA RAID 2x Xeon / 2x 160Gb I am trying to install Centos 4.2 kernel 2.6.9-22, but the simple driver is not accepted. Does Redhat support SATA? Thanks for your help Roland Brouwers
