Sorry Dan perhaps I didn't make myself clear.
I get your point about moving the jumper (to pins 1-2) to enable flashing of the ME.
But regardless of the jumper position, in BIOS it shows ME as being disabled.
Moving the jumper to the intial position, pins 2-3 has no effect on what is reported via the BIOS , ie that ME Firmware Version and ME Management Mode is Disabled.
