s5000psl installation issues

["Tommy Fullington" <tommyfullington gmail com>]

I am currently trying to install redhat enterprise 4.3 on a intel s5000psl board using raid five, I have installed Suse 10.2 enterprise on this board (using the megasar raid drivers.) and the only problem I had was needing to change some setting in fstab, grub loaded and the system ran just fine. After I install rhel 
4.3 however grub doesn't even load, so it leads me to believe that this is a problem with the version of grub not a kernel problem/install problem. Any help would be greatly appreciated, GREATLY. I've been working on this at work for a month now.
