Greetings. I am in the process of installing 5.1 64 bit on a server. The server has 2 3ware cards: 9550SX 12 port, and a 8006 2 port, both SATA. I want the 8006 board to be /dev/sda, and the 9550 to be /dev/sdb. My plan is to install the os on /dev/sda (8006), and data on /dev/sdb (9550). Unfortunately, the 9550 comes up as /dev/sda. The 8006 is installed in slot 3, which is a 100Mhz slot. The 9550 is installed in Slot 4, which is a 133Mhz slot. I really don't want to put the 9550 in the 100Mhz slot. I'm not even sure it would make a difference... I would also prefer to not have grub reside on /dev/sda, while the os is on /dev/sdb. I have tried to change the boot priority in bios, but this hasn't changed the priority. I tried to disable one of the boards in the bios, but that didn't seem to have any effect. Interestingly enough, when I boot with the Knoppix 5.1.1 live cd, the cards show up as I want them to. I have searched Google, but I am either entering the wrong search parameters, or there isn't anything out there, at least pertaining to the initial installation. Any ideas are appreciated. Thanks in advance. Monty Specs: Supermicro X6DH8-G 3ware 8006-2lp pci-X 3ware 9550sx-12, pci-X CentOS 5.1, x86_64, network (nfs) install
