SAS PERC H200 Linux Driver

I'm trying to install CentOS 4.8 using the SAS controller card mentioned in the title in a Dell PowerEdge T110 II.

I seem to have located a Redhat Enterprise 4.8 driver for the card, but that driver does not seem to work with CentOS flavor. I read something about the driver may be signed to only work with Redhat Flavor.

Is there any solution to finding a compatible driver, or maybe compiling my own CentOS driver from the source?

Here's the link to the driver I found:

ftp://ftp.dell.com/sas-raid/R245295-mpt2sasbtm-02.15.00.00-2.txt

Thanks for any help.

P.S. I know this version of Linux is out dated but it is the version we need to use for database compatibility reasons.
