Hi to everyone
I was been absent for ages as my job has taken over. I'm already running Catalina 10.15.7/O.C. 0.6.0 and I'd like to begin with Big Sur and I couldn't follow the evolution to the latter.
At this time, my build is so composed:
1. ASUS SAGE/10G
2. 128 GB RAM (16x8)
3. Radeon VII (slot 1)
4. Titan Ridge TTB3 (slot 2)
5. HighPoint RocketRAID 2840A (slot 3)
6. MQUPIN FENVI T919 Scheda Wireless BCM94360CD (slot 4)
7. HighPoint SSD7101A-1 NVMe RAID controller

Can someone, who runs a similar build, share his EFI, please?
@Ghostmac1969 Did you get the HighPoint SSD7101A-1 working on Big Sur? I have nearly identical set up running OC, and haven't had any luck. Currently in slot 1. Could you share you EFI? It was all fine on Catalina.

Hello everyone! I am having a problem where en0 wont showup (only lo0 is) for my network interfaces even though im injecting IntelMausiEthernet.kext. I am using opencore 0.6.9 is it not injecting or did i miss something entirely? Any help would be appreciated? I can get into the main installer but even with my ethernet cable plugged in it says it needs to connect to the internet to download macOS...

Never mind I fixed it! I didn’t enable the actual key whoops

Last time I did a clean install of Big Sur, I had a frozen mouse too but it eventually finished installing. You can refer to my github for recommended BIOS settings and my BASE-EFI that should work. I also have a Sage/10G EFI too but it’s more customized to the specific devices I have.

Good luck!

good days,

i am confuse now. motherboard Asus X299 Deluxe II, and the newest BIOS is 3301.
previous BIOS 0802 so far so good on macos.
but i upgraded BIOS to 3301 last night and i no longer can boot into macOS via Opencore....

bios 0802:
i have one issue, if i enable CSM in bios and boot into macos, all USB port dead.
any solution for such issue except to disable CSM?

I'm having the same issue, I think, but the opposite.

The 6900 XT does not allow the machine to get past the BIOS splash screen if CSM is disabled.

USB ports not working at all. They show in IOReg, but no power.

@applemacosxGOD did you ever figure this out?

I'm on a Designare EX x299, BIOS F6


Edit: I figured it out. The solution was to disable ProtectUefiServices under Booter > Quirks.

CSM Support is still enabled with the following sub-categories:
– LAN PXE Boot Option ROM: Disabled
– Storage Boot Option Control: Do not launch
– Other PCI devices: Do not launch

X299 trouble

Hello there, I've just tried to make a clean install, but after dozens of tries with Dortania's guide and this thread, I cannot reach the Big Sur installation GUI.

It seems that everything loads well, but errors will appear with:

“disks3s3 device is write locked". The USB stick is a 16Gb USB 2, on a USB 2 port (I've tried them all and 3 different sticks).

In the end there’s a failed to bootstrap path error on many items :

I try to run on an ASUS X299 DELUXE and the Bios version is 3301.
I only have one ssd plugged and nothing bu the installation stick and the keyboard.

If someone skilled enough could tell me what I'm doing wrong, I'd be thrilled.
