OpenCore bootloader with development SDK

[PlexiPuter]

How do I get my i7 8700k showing up as a Xeon in OpenCore?

On Clover, it was 0x0A05 in CPU type but I can't seem to get this to change from i7 8700k in OpenCore.

u checked manual?

[PlexiPuter]

I have but it's not an obvious fix.

Tried Hex swapping it...etc..

Does anyone have a guide as to what needs to be done to make Windows 10 boot from OC? I get a acpi bios error when trying to boot windows from OC but boots fine for UEFI boot menu but i would prefer to use bootloader (wife friendly)

u need use _sta for devices

i think devs fix it soon, is a very non-sense for one good bootloader

From what i have read they have no plans of "fixing " windows booting.

Where abouts do i insert that in my DSDT?

Well this is the DSDT you made for my machine and its working great from what i can tell. Are you able to add the "windows" features so i can boot windows 10 through OC please?

I've now tried OC with just the SSDT's and also with just MaLd0n's orig DSDT's that he made for both my Z370 and H270.

Everything works better with MaLd0n's DSDT's.

I've been running a bunch of hacks for 10 years, and they've ALL been with the help of MaLd0n's amazing grasp of all things ACPI.

Many thanks to MaLd0n!

 

Hope you're well, and much appreciated

Just Enjoy!

What I've ended up doing on OpenCore, is making sure the DSDT I'm running on, is fully renamed.

Then, I put SATA and IGPU in a Kaby and  SATA, IGPU, and HDEF in a Coffee, in as a patch, but I set it to rename just the table SSDT's.

Rename only seems to work on generated tables in OC.

This seems to be the best I can make these two machines run on OpenCore, but they're running spot on!

I know the OC manual states against renames but I didn't put OSX on a Pee Cee to run windoze myself

ssdt is a pseudo solution, is not a full solution

same way work in clover too

[PlexiPuter]

Yep. I like the idea of having eveything working from the DSDT.

Hi Maldon, 

I am trying to replace Clover with Opencore, I have used your Clover EFI and Dsdt , it has been working perfect. But when I try to boot with the Opencore Efi , it stops at "AppleIntelLpssI2CController::_serviceMatchingTimeSubr: fTimerServiceMatching timed out," and  It flashes waiting for Root Device  then scrambled screen. 

 

I didn't change anything from your EFI folder and was using Opencore as legacy. My Laptop supports UEFI but somehow Mac won't boot on UEFI with my battery in. Same case for clover and Opencore.

Hi Maldon

if u have a perfect hack with clover why oc?

 

[Shahzad]

Actually I had some issues

1. Clover takes long time to boot, around 1min or so, and tried to clean it up to make to faster but anything I remove, breaks it so tried oc.

2. My laptop microphone doesnt have proper gain, like I can only hear tapping on the microphone, nothing else. I tried to use some guides to patch it platform.xml files but failed. 
like this one-

https://github.com/F0x1c/AppleALC_Instructions/blob/master/README.md

3. And I always wanted to use Uefi but didn’t know untill trying to work with opencore that its Mac, not the bootloader thats the issue.

[vamoose]

Thanks for your help.

 

can you also suggest, the best video card with 4K resolution for office work/ basic computing .

Should be compatible with Catalina & up for future.
