You can connect out-of-band using dedicated VNC-compatible viewer technology, and have full KVM (keyboard, video, mouse) capability throughout the power cycle—including uninterrupted control of the desktop when an operating system loads.
I will be focused on updating through EFI rather than Windows or DOS. It is probably best to do this in case something goes wrong : P 9 After the update, reboot and you are done!

If the power state permits it, Intel AMT Release 2.5/2.6 can continue to send and receive out-of-band traffic when the platform is in an Sx state, but only via a wired LAN connection, if one exists.
Release 4.0 and later releases support wireless out-of-band manageability in Sx states, depending on the power setting and other configuration parameters.
Release 7.0 supports wireless manageability on desktop platforms.
