Things are slightly different in DQ57TM BIOS. You access the AMT settings from inside the BIOS. There is no CTL-P screen.
However you should not need to access AMT settings. In most versions of DQ57TM BIOS you access the RPAT options by hitting F9 at boot (same time you would hit F2 to enter BIOS). That should bring up the RPAT menus.
Hope this helps.
Unfortunately when I hit F9 I get some white text that flashes on the screen too quick to be able to read and then it goes right into Windows.
Again I am able to access the system including bios and all using "VNC Viewer Plus" Trial edition. But I cannot get any access to RPAT (Which is required for LogMeIn). When I run the "Intel Management And Security Status" tool that loads in the taskbar on the "General" Tab it shows "Intel AMT" enabled, "Intel RPAT" DISABLED, and "Intel AT" Enabled.
Also In the Bios there is no mention anywhere about "RPAT".
