AsRock X299 Creator

[oli.mathieu]

Some of you, guys, is already on BigSur?

Yep
Installation is painful due to the broken NVRAM.
Follow the @TheBloke 's procedure : X299 Big Sur Support #1,063
It worked forme with BS 11.0.1 but failed twice with BS 11.1
Hope this helps

POST is very very long with this Mobo
IS there a way to make it quicker it ?
I suspect the Boot LAN capabilities .... that appears in the UEFI BOOT Option even after I previously & manually disabled them.

Thanks, I am pretty interested in your MB, could you be so kind to tell me what it’s working and what isn’t?

What isn't working (as far as know because I use)

• Bluetooth
• NVRAM needed for :
  • Installation for BigSur
  • Update for BigSur
  • Prefpane ➧ Startup Drive
  • Dualboot with Window10
• Persistent Boot Option in UEFI as soon you plug an new drive (I use 6 SSD trays)

What I know is working

• All SATA & NVME ports
• Hot-plug
  • SATA (with patch)
  • Thunderbolt (with SSDT)
• USB partially because I still didn't build a specific Kext
• Ethernet
  • 1G
  • 10G (with patch for Big Sur)
• Wifi
• Optical audio output
• iCloud, AppStore
• SMBIOS MacPro7,1 without memory error
• Sleep & Wake

What I don't know because i don't use

• Sidecar
• iMessage

Thanks! Probably BT (and Wi-FI) can work OOB if you get the right card instead of Asrock's one.

The NVRAM is really a big pain ... I hope it can be solved sooner or later.

What about power management? Sleep and wake?

Sure, but it's extra cost.

I want to believe that

Power management is working,
Monitor sleep and wake .... I don't know about the computer .. i'll test
EDIT
In fact it works ➧ My Big Sur installation has left the Energy saver's first checkbox unchecked

@oli.mathieu, have you upgraded to BS 11.1 yet? And which OpenCore? I am still stuck on 11.0.1 on OC 063... Thanks!

Thanks, @oli.mathieu! After updating OC, can you update to BS 11.1 normally or using @TheBloke's workaround? Cheers!

No I didn't try updating
i did

1. A clean install with BS 11.1 on spare drive
2. Migration User account and Softwares
3. Clone back on the original drive
