Asus P8Z77-M RT-d Unlock

[cbaldwin1]

Hi all,

I am wanting to get hardware pass-through working in a machine that is using ProxMox. It is running on a P8Z77-M board with 3rd gen i5 - 3550. From what I can gather, Asus' P8Z77-V lk board has RT-d enabled by default as a hidden option. I was wondering if there is anyone who has tried to implement this feature on their more budget P8Z77-M board? AsRock did a pretty good job of having RT-d as an option in a lot of their Z77 boards:

Asrock Z77-Pro4-M
Asrock Z77 Extreme6
Asrock Z77 Extreme4
Asrock Z77 Extreme4-M
Asrock Z77E-ITX

Gigabyte and MSI also have a couple between themselves:

Gigabyte Z77MX-D3H
MSI Z77A-G43

I'd love to hear some thoughts on this?
