Peter-
Build the array in the 3ware bios. Reboot and reinstall onto the array. The 7xxx and 8xxx series cards just work with CentOS. They are treated a scsi disk.

Sean and Peter -
If I was reading the correct specs, they said Linux up to RH 9. It is compatible with Centos/RHEL?
I may go with the 2-port version and just RAID two-80 GB drives and keep my 2-30 GB drives as extra storage.
*** Can I pre install Centos on one of my 80 GB drives and after the controller arrives, plug the 2-80 GB drives into it and then mirror the drive?

I have not used RAID controller boards to date since I have relied on the built in RAID on the motherboards. Thanks to the informative message Byron, I realize the deficiencies of doing RAID 1 this way, especially now that the builtin is out of date with Kernel used by Centos.
I have 4 ATA drives that were configured in two pairs. I assume that I need a 3Wave controller that has 4 ports like the 7506-4LP...correct?
Do I need to install any software during the installation of Centos?
Todd-
The installation will recognize the 3ware card and the arrays that you build on it (you do this in the card bios Alt+3 at boot). As Peter said, you'll want to make sure the card is using the latest firmware (you'll need a dos boot disk and a floppy with the firmware utility on it, comes as a zip file from the 3Ware site) -- iirc, the latest version is 7.7.1 for 7xxx and 8xxx cards. You also probably want to get run the 3dmd utility as it will notify you about failed disks and other issues by email and can do background media checks... very nice.
