[CentOS] Rapid deployment of CentOS on HP Proliant machines

Has anyone successfully deployed CentOS on HP Proliant servers using the Altiris Rapid Deployment (RDP) framework? This works out of the box with RHEL 5.1 but I have not been able to get this to work with CentOS 5.1. If anyone knows of an article on all the details to be able to deploy CentOS to a bare machine Proliant Server, I would appreciate a pointer. I did make the changes to the adlagent installation to add the "--install-as=redhat --toolbox==redhad" and that allowed me to get much further along in the process. My end result is that instead of booting to CentOS after the RDP job is done I get a notice that "Admin" is not a valid boot option.

Any info would be appreciated.

Thanks,

Fred
