Hi
Need help modding Asrock Z87 extreme9/ac Bios to set all PCIe to gen1 by default.
The original bios (and all updates) allows to change only PCIe2 to gen1.
Thanks.

@racminer :
Welcome at Win-RAID Forum!

I am sorry, but I cannot help you with this. Such modification is too difficult and risky.

Thank you for your answer.
I am willing to go forward and there is no much risk really.
This mobo has dual bios …
thanks anyway.

By the way, Wardog from http://forum.asrock.com says “Hi” .
