VMware Update Manager baseline setting

Hi All,

I just installed 2 new ESXi 5.1 host and VCenter 5.1 as well as update manager.

How can I tell Update manager only download patch, extension for ESXi5.1 not for older version?

At the moment, when I modify/create a baseline, I can only see esx4.0, 4.1, not 5.x

Thanks.
