Invalid OS SP when installing sql beta 2005 IA64

When I run setup I get an error stating the OS is not at the required Service
Pack. I looked over the requirements and Data Center with a build over 1138
was suffecient. I am running Data Center IA64, and I am trying to install
2005 beta dev IA64.Can you please post to the SQL Server 2005 newsgroups?
