[CentOS] Problem installing CentOS 5.0

I decided to replace Suse 10.1 with Centos 5.0 on my file server. Im getting stuck right after I select the keyboard layout.

I get the following message on the console:

/dev/sdb: "sil" and "pdc" formats discovered ( using pdc)!

and it just hangs there. I think sil and pdc are referring to the onboard raid chips that the drive was attached to. This drive was used in a machine with a Silicon Image raid chip and a Promise raid chipset in the past, now its attached to onboard nvidia based controller but not in raid mode. I tried to low level format the drive and it sill did not work. Any ideas, I don't have this problem with Suse or Freebsd.
