Hmm, Intel SCS 10 was fully validated with AMT 6 or newer -that is why this version is listed as the lowest supported.
I have asked SCS 10 development team if they have removed any pre AMT 6 related code modules and the answer was NO.
So SCS 10 shall be able to configure AMT 2.2 or newer altough it was not tested by Intel as such systems are very old (AMT 5 is 2009 platform -6 years old already).
I have AMT 4 system in my LAB - can test it with SCS 10 first days of January 2016 will let you know.
BTW AMT 5.01 is pretty old AMT FW - please check OEM website for updates - you shall look for ME FW 5.2.50.1039 which is the lates version that was published by Intel to OEMs.
