driver download - RAID Controller

I have PowerEdge 2450 PIII 733 Mhz 2U with two 9gb scsi drivers. Currently installed Windows2000. I've tried to install Centos4, but it did not find hard drivers. I went to Dell Driver download site for 2450, but I'm confused what to download.

During the power on self-test, it shows that I have LSI Logic PERC as shown below.

Here are my questions.
