Asus X99 Rampage Big Sur 11.0.1 running smoothly with Opencore 0.6.3

Can't wait to share with you guys my X99 Asus Rampage with RX vega 64 boots and running smoothly. I tried with Macpro 7.1 and iMac pro 1.1 both smbios. No problem!

Thanks for sharing your EFI folder, I'm taking my first shot at Opencore and that helped me immensely.

I created an installer for Catalina. The installer runs about 80% of the way then I get this error. Any ideas on what I need to tweak?

I removed DiskArbitrationFixup.kext and was able to complete the install. The only issue I'm seeing so far is that my monitors will flicker 5 or 6 times every so often. Otherwise it seems stable. This is awesome, Thanks again for sharing your EFI folder @shantonu, you really made things much easier!

I get "OCB start image failed; aborted.
Any suggestion?
Thanks

Thanks for sharing the EFI folder. Saw this post and tried today. And the shared EFI folder works - without any modification

OS: macOS Big Sur 11.1
MB: Asrock X99E-ITX/AC
CPU: Xeon E5 2630L 1.8G
Ram: 32GB
GPU: EVGA GT710
Wifi: BCM94352
Monitor: Cinema Display 30

For the longest time I was not able to upgrade this machine from Catalina to Big Sur. This time it works. I hope this confirmation will help those who have the same motherboard and still trying to get to Big Sur

These are my steps:

On another mac (Mac Pro 2009):
- download shantonu's EFI folder
- download macOS Big Sur 11.1 (20C69) using gibMacOS
Use ethernet to download -anytime I use wifi to download.
I eventually met "install media damaged" during installation.
- create USB boot disk as usual
- mount EFI partition on USB - using MountEFI utility - copy Shantonu's EFI folder into USB EFI partition

On target Hackintosh (X99E-ITX/AC)
- boot - select USB in BIOS - format target HD - install
- during installation - there will be 3-4 times reboot
I still selected USB boot in BIOS - so the computer will not boot into another hard drive I have with Clover on it.
- Once installation is complete - I mounted both EFI partition on HD and USB
copied over EFI folder from USB EFI pairtition to HD EFI partition
- Select HD as boot drive in System Preference - Startup Disk
- remove USB - and reboot - Opencore shows available boot disks and default boots into Big Sur on my HD

Thanks for the community to share this knowledge and made Big Sur possible on this very unique ITX Hackintosh build.

Hi Shantou

Your EFI works very smoothly with my X99 Xeon cpu and installs perfectly. However, it does not boot with my i7-5820K cpu. Any idea.

Anyway, thanks a lot

Try this OC 0.6.4 EFI

 

[shantonu]

Hello! Your EFI is very useful. I can install it now. However, after installation, ‘disk write clocked’ will appear. And then it's rebooted! My machine configuration is "x99 deluxeii + rx580".

Try this EFI from 0.6.4 OC

Hi @shantonu , do you upgrade from Catalina or clean installation?

Thanks for your new EFI 0.6.4. However I'm getting the same "OCB start image failed, aborted" error message. I wonder if it may have anything to do with my MSI X99 SlI motherboard.
Thanks again
