[CentOS] install on a Dell4400 perc2 /DC

I got fedora core 4 to install and show me the configured Raid drives.
no mean trick let me tell you. However, the platform is unstable and
hangs. I tried Centos 4.1 but the raid drives are not identified like
most other distros. can i do anything from the fedora install that might
allow me to install the centos distro. I would rather not have to go out
and buy a new raid card.
