Could you please explain in more detail what happened when you could not fully update the BIOS? Were you trying to change to a newer version of the BIOS or just trying to change some settings in your current BIOS?
Also, could you clarify what you are trying to accomplish? Are you trying to enable Active Management Technology on your system so you can use it's features?
If you are just looking for some information on Intel Active Management Technology, you may find some answers in the Intel VPro Frequently Asked Questions. You may also find what you are looking for in the Architecture Guide which has a good overview of features and some information on the Management Engine.
If you are still having issues, I would refer you to Email TechnicalSupportas this issue is related to the BIOS/Firmware update.
After looking at the specs for your board I should also point out that it does not support Active Management Technology as I first assumed. Your board uses a management engine to enable Intel Quiet System Technology.
