Yes we have contacted ASUS and they say that ME updates do not exist. We have subsequently contacted Intel Support and they have confirmed that ME firmware updates for Q77 and Q87 chipset systems specifically ASUS motherboard models p8Q77-M, Q87M-e and Q87T have been delivered to ASUS. Subsequent followup with ASUS has not yielded a response.
If you could follow up with your ASUS contacts we would sincerely appreciate it .
