I managed to unlock all settings, like PCI subsystem and ACPI settings, and QPI/IOH settings, in addition tons of PCH setting, even some weird stuff like int19 trap response with GateA20, and even Super I/O settings for FDC/RS-232 ports, etc..
In short - SUCCESS, all settings unlocked, my current goal - revert GUI back to stock AMI one.
Also updated PRO1000 OPROM + Marvell one, RSTe/IRST/mC next…
Also updated ME to 8.1 through a pretty weird method, first download P9X79 Pro bios with rebar + nvme,
(flash thru UBF)
then check bios and check for ME, if ME is N/A, then go to asus ez flash 2 and flash original BIOS. It will revert the N/A, and it will update ME without spikes in the tiers.
And i even removed somewhat useless spacing between options, it made it look more compact and less messy!
And even found tons of duplicated things! like 2 CSM options for some reason…
