Hey there Jeff,
Don't have a fully baked answer for you right now but with regard to the ips-schema being stored, you can reference the following URL for schema details:
Intel(R) AMT SDK Implementation and Reference Guide
For your second question...
How else can I configure a system with AMT for VNC connections?
Clarifying question on this...
Do you need to simply "set" AMT KVM settings? Or do you need to "configure and set" AMT KVM settings?
The first one will be easier to answer whereas the second one will be more complex.
Regards,
Michael
