Gigabyte Z170X-UD5 Bios update -- Clover/macOSx doesn't see graphics card now

[tamorgen]

I updated my BIOS (silly me) to the latest F22 bios (03/06/17), and now my Hacktinosh will only boot into low resolution, and icloud thinks it's a whole new machine. I have a GTX1080 graphics card, the integrated graphics are turned off, and the Inital Display Output is set to PCIe 1 Slot (verified in BIOS and on MB). Clover also loads at low resolution, where it would load at a high resolution before.

I verified that it is hitting the config.plist by changing the Theme in clover. I tried resetting and deleting the NVRAM.plist. I've tried reinstalling Clover, as well as reinstalling the Nvidia drivers.

I'm dual booting, and Windows 10 behaves just fine after the BIOS upgrade.

Any ideas?

Any ideas?

The BIOS upgrade removes native NVRAM support and now it must be emulated.
Install EmuVariableUefi-64 and RC scripts or install OsxAptioFixv3.

Thanks Pilgrim. Is there a preference? What is the difference between the two methods?

The first is the old way and the second is the new - Either should get the job done.
