I've just downloaded the Managability Developer Tool Kit v.0.6.09037.2. I'm using the Commander Tool to connect to a Dell Optiplex 755 with BIOS A15 and AMT Version 3.2.10. Until now I've only used the web interface to this machine.
The main thing I'm looking for now is remote access (Serial over LAN), but on the Intel Management Engine tab, next to Remote Access, it says "Unsupported." Why is it unsupported? What would be involved in allowing me to get to the BIOS-level diagnostics (F12) via AMT?
