RedHat Application Server is not an operating system. It is a framework for developing and 
running Web Applications.

They are different processor architectures.

What you need is RedHat Enterprise Linux. The latest version is 5.2. There is no longer 
any AS/ES distinction. Login to your RHN. Click on the Download Software icon on the left 
of the page. Then follow the link to "Red Hat Enterprise Linux (v. 5 for 64-bit x86_64)" 
(don't expand the "+") and download the Binary DVD iso.

If you really do want AS or ES (RHEL 4) then there are links to the download sections for 
older RHEL versions on the same page e.g. "Red Hat Enterprise Linux AS (v. 4 for 64-bit 
AMD64/Intel EM64T)".
