[CentOS] install 5.5 x86-64 on DL320 G6

I am trying to install on a DL320 proliant.
The disk is not being recognized. It fails when setting up disk with "no 
devices" found.
I dont get an sda or cciss either one.

I tried to disable the on board smart array controller? That didnt seem 
to make a difference.

Is there something special I need to do?

Thanks,

jerry
