There's an MSR EFI left from Step 2. "Unlock MSR 0xE2
I cannot isolate to a single " EFI" folder from that and I cannot compress the "MSR EFI" by right clicking..sorry.

I just deleted a few kexts from Step 3 and now am scratching my head trying to find " Kext Utility" to rebuild the Kernel cache.
I've attached it below.
Of important request: I have 7 usb 3.0 drives yet only one usb 2.0 which has the Unlock MSR 0xE2 on it.
do you know a quick way to inject a usb 3.0 so I can use it in steep 6-7? You are correct Casey, I am using the Mojave to Catalina guide
For Steps 6 and 7 any USB 2 or USB 3 flash disk will work. Even a small 2GB USB flash disk will be okay.

I read something on reddit about using Terminal : Pseudo kextcache -i /
Anybody use this method successfully ?
Yes this will also work: sudo kextcache -i /

When I was using the Gigabyte Gaming 7 (Z370) I couldn't get any 3.0 USB ports to work, so I thought no flash drives will be accepted/registered. I finally got one Samsung to be recognized out of 6 odd SanDisk's, Corsair, Kingstons. lol

If I receive a Kernal Cache ID: 5C2A .............38 numbers after, is this a win? Since one post instructed the user to await a done on the lower right of the Page o_O

Seems like I lost my LAN/Internet connection after the Terminal kext config.
I have a windows desktop beside me. Is there a way to download Intel Mausi to revive my port, or a work around?
Thank you so much and please tell me how to donate to the forum/support ?

Sorry but I thought about Clover and quickly found a way Casey :
That file does not contain a CLOVER folder.

Because you're following the Mojave-to-Catalina upgrade guide, all kexts are located in the ZIP file attached to the Catalina Mini-Guide. You're always welcome to contribute to the site by clicking the Contribute button at the very top left of the web page.

@scottkendall, have you tried the minimal 3 patch approach on the active partition of the Rev1?

2727->3737 at offset 0x35 (decimal 53)
A0 -> 20 at offset 0x81 (decimal 129)
FFFFFFFF -> 8680D315 (or whatever your controller device-id is, byte reversed) at offset 0xBA0 (decimal 2976)

It has worked on all the Alpine Ridge firmware I've tried so far (Intel Hades Canyon15d3 and Asrock Z370 itx/ac 15c0)
@dgsga @CaseySJ @scottkendall: I would be happy to start digging into the firmware and patching it myself. Is there some documentation / summary of the reverse engineering progress so far? Will give it a try to just follow the instructions but I usually prefer to try to understand what's happening.

Is my only option to Revert or is there something I can Modify in the Clover Boot menu to keep my progress?
If Reverting, do I need the backup I created in Step one of the Micro-guide ?

Let's start over:
  • Motherboard: Gigabyte GA-H170-HD3 with on-board Thunderbolt header
  • GC-Alpine Ridge installed into second PCIe 3.0 long slot?
    GA-H170-HD3.png
  • Thunderbolt Header connected?
  • The second PCie 3.0 long slot appears in IOReg as RP05?
  • Operating system: Mojave or Catalina?
Which devices have you tested so far?
  • USB-C flash disk or other simple USB-C device?
    • Does it work when connected to either of the two Thunderbolt/USB-C ports?
  • Razer Core X eGPU is a complex Thunderbolt 3 device. Do you have any simpler Thunderbolt 3 devices such as:
    • Thunderbolt 3 dock
    • Thunderbolt 3 SSD
    • Thunderbolt 2 device connected via TB3-to-TB2 adapter

You can try this:
  • Connect the backup disk.
  • Reboot computer and press F12 at BIOS splash screen to open the BIOS boot menu (not Clover boot menu).
  • Select the backup disk from this menu.
  • Now Clover Boot Menu will appear.
  • Boot macOS from the backup disk because that disk should have the Ethernet kext.
  • Then download/copy IntelMausiEthernet.kext to the CLOVER/kexts/Other folder in the EFI partition of the USB flash disk.
  • Reboot, disconnect the backup disk, and press F12 at BIOS splash screen to select the USB flash disk.
  • At the Clover Boot Menu, boot macOS from the internal SSD.
