Asus has released BIOS updates for all of the 9-Series motherboards over the past few weeks. If you update to these new BIOS, the SSDT on the DMG will break. I have found how to correct the issue, but I need to do it on a case-by-case basis to verify that the solution will work on all boards. What I need are DSDT extracts and IOREG Files from the system after the BIOS update and I will correct the SSDT’s and add the updated files to the DMG.

Please post links to the Files here in the comments. Thank you for you assistance and support.
