Although I haven't checked, I like your idea to enable VT-d in BIOS and try again.I'm assuming we need to have VT-d enabled in the BIOS to have the DMAR table show up in the ACPI registry?
@ncortines @canyondust,My thoughts were correct! DMAR attached:
Please use the attached SSDT-DMAR and follow the rest of the steps from this post:
I find the solution to fix the issue that HEVC don't work. before: after: CaseySJ, Could you please add this fix to the new efi? how to fix: add # before AAPL,slot-namewww.tonymacx86.com
This file is for Gigabyte Z490 Vision G only.
P.S. To anyone interested in doing this for themselves on their own DMAR tables: Simply delete all Reserved Memory Region blocks (highlighted below) and save the file as SSDT-DMAR.aml.

Hello @mm2margaret,Hey, @CaseySJ:
Thanks for the 0.7.1 efi, seems to be fine, with one exception (please note that I am using the debug version of 0.7.1 opencore)
"No Valid Serialized Value at 0 index"
I did some searching and couldn't find anything, both in the EFI and on the web. Do you or anyone else have any idea what this is referring to?
This indicates a syntax error in the XML schema (config.plist). One quick remedy is to run OpenCore Configurator, place it into OpenCore 0.7.1 Development Configuration from its Settings page, then open your config.plist, click through the various sections on the left side (ACPI, Booter, Device Properties, etc.) without making any changes, and save the file.
Reboot and check again...
