[CentOS] changing partition priority on install

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
