I understand that you are not able to get in to the AMT option during POST.
I have tested this and I was able to get in to the menu by tabbing both the cotrl+P keys at the same time during POST.
Hope this helps.
looks like my original message is rather unclear. I do hit Ctrl-P repeatedly during POST, but instead of the AMT configuration menu I just get a message saying "FW Status Recovery Error". After a second, or so, the boot continues to Windows. I also tried without the HDD, but got the same message.
So the question is, do I need to do something else to enable AMT or is there something wrong with the board?
Did you manage to solve your issue? I unfortunately run into the same problem.
Just an update: a BIOS upgrade fixed this issue for me, on a Kontron KTQ67 motherboard. Note that an upgrade will delete all previous configuration and passwords.
