I have a 3ware 9550SX(U) that doesn't show up to OSs. This is strange because LSI says Openfiler(Linux) has native drivers in the kernel. Also when Int 13 catches I get a list of the 6 Drives I have installed, but when I try to press Alt-3 I get "3Ware BIOS isn't installed". Being able to setup arrays from BIOS and run Hardware RAID would be great, but I would be happy if I could just get Linux to see the drives attached to the card and run a Software RAID. I installed Openfiler to one of the mobo sata ports.
