Hi all, Installing 5.5 on a fresh system having an Intel RAID. My 2 drives are configured as a mirror within the Intel BIOS. When starting my install, Anaconda throws an exception. After a brief goog, I see one possible fix is - at the install prompt, type; linux text nodmraid This is fine and all but Centos sees 2 disks at this point rather then 1 which is what I thought the Intel RAID controller would present to the OS. I am pretty much tarded when it comes to installs as I usually boot of a DVD, enter some choices based on requirements and off I go. I once compiled a network driver into the initrd and remade my boot disk but that seems beyond me now. Any help is greatly appreciated. - aurf

Some RAID cards rely on OS software to do much of the RAID: they're jokes, really. If it's a real RAID chipset, no Linux or Windows kernel should even be *AWARE* of the multiple disks, except perhaps for some limited reporting tools. Exactly which chipset are you dealing with?
