I'm guessing the easiest would be using a USB Installer from 10.11.0 or less. I'm not sure if its possible to disable from EFI SHELL, I'm guessing you can, however I am not sure how.

 

edit: Found this some pages down:

setvar boot-args -guid 7C436110-AB2A-4BBB-A880-FE41995C9F82 -nv ="-v"

setvar SystemSerial -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="C02KP025F8JC"
setvar BaseBoardSerial -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="C02KP025F8JCF325D"
setvar BiosDate -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="03/09/13"
setvar BiosVersion -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="IM142.88Z.0118.B00.1309031249"
setvar ProductName -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="iMac14,2"
setvar ProductFamily -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="iMac"
setvar ProductId -guid 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 -nv ="Mac-27ADBB7B4CEE8E61"

So using the same format it would be something like:

setvar csr-active-config -guid 7C436110-AB2A-4BBB-A880-FE41995C9F82 -nv ="ZwAAAA=="

Could someone confirm or deny?

[mhaeuser]

It is possible and was explained a few pages back. Search this topic for 'setvar'. I can't, using my phone.

Yea I did search, however, there's no specific example for SIP or...IM BLIND. lol.

 

Does this make sense:

setvar csr-active-config -guid 7C436110-AB2A-4BBB-A880-FE41995C9F82 -nv ="ZwAAAA=="

?

[mhaeuser]

I don't have all parameters in my head, but I would use Hex/Integer, if available. Base64 is not going to work.

Hi,`

 

Why you don't put it in Defaults.plist ?

 

Defaults.tiff

Well after trying to re-flash and use my Yosemite USB stick, now I can't even get into the BIOS. I've tried everything - removing the board battery included. Both the main and backup BIOS stick on code Ab, with no signal to the monitor at all. I've tried removing all cards and RAM sticks except one, tried to force the backup BIOS to kick in - nothing. Is my board fried?

[mhaeuser]

Sorry, but it is in no way related to Oz.

Maybe, in an own thread, you can say what you 're-flashed' and what was flashed before to provide at least some useful information.

[alecwild]

Apologies. I was finally able to get into the BIOS (it was a SATA cord issue I think). However, after flashing Oz, 167x.F6, and starting up off my Yosemite USB stick (the one I originally used to install yosemite with this board), I'm getting an Apple logo and progress bar that stops almost halfway through, and then the computer shuts down. My BIOS settings:

 

• SATA-Mode: AHCI
• xHCI-Mode : Auto
• xHCI-Hand Off : Enabled
• EHCI-Hand Off : Enabled
• VT-d: Disable 
• Wake On Lan : Disable
• Fast Boot: Disable
• Secure Boot : Disable
• CPU EIST : Disable
• RAM mode: Optimize for stability. 

These are the settings that worked the first time I installed yosemite with Oz and this board. I've never installed clover, so I don't know how to boot in verbose mode.

 

Any help? Here's my Oz:

You need to disable nvidia drivers for the 960.

[alecwild]

I removed the 960 and am trying to install with just igfx. As I said, install hangs about halfway through the logo/progress bar and the computer restarts.

Verbose mode is your friend! Check what happens.

[alecwild]

How do I initiate verbose mode w/o clover or Windows?

@alecwild here you go:

Just like a genuine mac. Cmd + V

[alecwild]

Thanks @crusher., for that ROM. I don't know why, but El Capitan booted fine after I flashed the BIOS. Great!

 

Now I still have two issues: I've placed kexts in EFI/Efi/Quo/Darwin/Extensions/Common, but they're not loading (FakePCIID, VoodooHDA, Intel1000e). Why is that? Is it weird that my folder on the EFI volumes says Quo instead of Oz?

 

Also, now El Cap isn't recognizing my Nvidia graphics cards - even though I have the latest drivers installed. Why is that?

 

I'm grateful for this board to ask all my questions!

[joe75]

if you have a "Quo" folder it means you aren't booting a recent version of Oz or you have a another left over ESP from an old OZ build

[alecwild]

Oz version is 167x.F6, so it must be a leftover ESP. Is that why my kexts aren't loading? Should I change the folder name to Oz?

[crusher]

Use and reset NVRAM and later see do you have a Oz folder!!!!?

QUO to OZ!!!!

I just found optimal CpuType for my CPU. 0x605,

It's found when you generate ssdt using Pike's script. 

Right after model listing, stepping and revision it's a "setup" line 0x0... you cut the second 0 in the line and you're done. (eg. 0x701 for i7, 0x605 for i5)

[alecwild]

What's the best way to reset NVRAM? Cmd+option+P+R or sudo nvram-c in terminal?

@crusher. Why did the rom you posted work to boot elCap? Is SIP disabled somehow in the rom? If I reset nvram, won't SIP be re-enabled?

SIP is disabled in ROM. Why you ask? If you have enabled you put Defaults.plist in EFI/Oz

Yes this is the best way for reset NVRAM-> cmd+alt+p+r

I have just installed GTX 960 to my machine and after Apple logo it is in restarting loop..so

Is there any way to add nv_disable=1 in boot arg without revising Ozmosisdafults in bios and without an EFI shell?? actually I don't have EFI shell in bios..

I have tried single user mode and entered 

sudo nvram 7C436110-AB2A-4BBB-A880-FE41995C9F82:boot-args="nv_disable=1"

But no effect..

Any option??

[pmcnano]

Boot with cmd+x pretty sure it disables nvidia

[mathew2005in]

@pmcnano

Are you mentioning about safe mode? but that is shift key right?

I tested with both but still rebooting...
