Hello, first I'd like to thank you for your fantastic work. The EFI and documentations are excellent, and I was able to gain a lot of time with them.

I have the latest (082.1) EFI release of yours, here is my Hardware:

Component Details
Board Gigabyte Z490 Vision G
CPU Intel Core i9-10900KF
RAM G.Skill Trident Z Neo (2 x 16GB, DDR4-3600, DIMM 288 pin)
GPU Gigabyte Radeon RX 5700 XT Gaming OC
Audio Realtek® ALC1220-VB
Ethernet Intel I225-V 2.5GbE
Wifi Fenvi T919 PCIe Card

I have made everything work except for the wifi of my Fenvi T919 PCIe Card, which uses the BCM94360 chipset. The Bluetooth of this card is working, though.

I have found this bit in the config.plist file:

<dict>
    <key>Comment</key>
    <string>DMAR replacement table for 3rd Party WiFi/Ethernet</string>
    <key>Enabled</key>
    <false/>
    <key>Path</key>
    <string>DMAR.aml</string>
</dict>

Which I enabled with no further success.

I'm stuck with a disabled Wifi panel, which I can't turn On:

Any idea of what I may do wrong?

I am not using WiFi on this board, so I can't help you with that. For some users it works, for other's it doesn't

Please read this https://github.com/5T33Z0/Gigabyte-Z490-Vision-G-Hackintosh-OpenCore/blob/main/I225_stock_vs_cstmfw.md

Also: If you use the DMAR replacement table, then you also have to enable the drop rule to drop the OEM DMAR tabe (in ACPI/delete)

I'm using MacOS Big Sur 11.6.5 so I did the following:

<key>#PciRoot(0x0)/Pci(0x1C,0x1)/Pci(0x0,0x0)</key>
<string>I225-V Patch. Required tor macOS 10.15 up to 11.3 only!</string>
<key>Count</key>
<integer>1</integer>
<key>Enabled</key>
<false/>
<key>boot-args</key>
<string>dk.e1000=0 -allow_assetcache agdpmod=pikera</string>

I still have the stock firmware so to achieve this:

I did the following:

<key>DisableIoMapper</key>
<false/>

Then I did the following which should be related to DMAR dropped / replaced

<string>Drop OEM DMAR Table</string>
<key>Enabled</key>
<true/>
<string>DMAR replacement table for 3rd Party WiFi/Ethernet</string>
<key>Enabled</key>
<true/>

I'm left with the DMAR (OEM) which I'm not sure what it refers to?

OEM = Original Equipment Manufacturer = the original, unmodified DMAR table. I think there's an error in my table, but this doesn't concern you, since you are using Big Sur

  • Vt-D needs to be enabled in BIOS!
  • DisableIOMapper = false
  • Original DMAR droppend and replaced
  • Disable the Booter and Kernel Patches for the VMM stuff:
    • Skip Board ID check
    • Reroute HW_BID to OC_BID
    • Force IOGetVMMPresent
    • Reroute kern.hv_vmm_present patch (1)
    • Reroute kern.hv_vmm_present patch (2)
    • Disable Library Validation Enforcement
    • Catalina Patch can be disabled but doesn't matter really
  • try without boot-arg dk.e1000=0

BTW: 3rd Party relates primarily to 3rd Party Ethernet Cards, not Wifi per se!

MathieuUrstein commented

Ok, I tried pretty much every combination, and the following worked for me:

Vt-D: Enabled
DisableIoMapper: Enabled
DMAR (OEM): No
DMAR (dropped/replaced): Yes/Yes

With that I have I225-V and the PCIe card working 👍
Thanks for your help.

Good to hear. But DisableIOMapper basically disables Vt-D in macOS so, you might as well turn Vt-D off.

@MathieuUrstein Can you please try with Vt-d disabled and report if it still works? Thanks.
