Installing Raid Drivers help for IBM xSeries Server

I need help installing the Raid Drivers for an IBM xSeries 346 server. I'm very new to servers, but I got it so I could learn. No matter what OS I boot up onto the RAM of the server, it cannot detect the hard drives. After researching, I'm suppose to install the RAID Drives onto the BIOS.

I have NO idea how to do this. Do I place it onto a cd and it will automatically install it? I've burned the ISO of the the IBM Installation CD onto a disc, but it can't detect my mouse, so I can't navigate what to do. I tried with just the keyboard, but I'm unable to select next after a bit.

So here's my questions I need serious help with:

-How do I install the raid drivers onto the bios?
-How do I get the mouse to work for the Installation CD? Is there an alternative method?

Thank you
