I am building a NAS for work and I picked up a HP P410 and a HP SAS expander card. The P410 confirguration option doesn't show up during boot. I am running it on an Intel 1200 series server board with a Xeon E3 1220. I setup the onboard intel RAID for the OS drives and those work fine. Any thoughts? The controller card isn't seen once I boot Red Hat either.
