Cannot boot without npci=0x2000 nvda_drv=1 (Already in .plist)

[BillStewart]

Hi guys,

I've nearly finished getting my x99 hack running smoothly, but I'm having a kernel flag issue..
The system won't boot into Yosemite unless I type these kernel flags at startup:

ncpi=0x2000
nvda_drv=1

I've already added them to my chameleon.boot.plist so I'm not sure what the issue is..

Does anyone have any tips?

Background info:

5820k
Asus x99-A 3
Asus GTX 980 ti
RipJaws DDR4 32GB

What I did so far: (Guide from Amad3us)

• Created USB Installation drive for Yosemite 10.10.5 using UniBeast
• Patched the Kernel of that Installation drive using the Code provided here: Haswell-E + X99 Motherboard Temporary Guide - OS X 10.10
• Added VoodooTSCSync.kext (6 core) to /Extra/Extensions on the UniBeast stick
• Copied the MultiBeast installer to the USB drive

• Booted the UniBeast stick using npci=0x2000 nv_disable=1 -f -x -v to install OS X to an GUID formatted SSD (from now on described as Yosemite SSD)
• After installation I booted the UniBeast stick again using npci=0x2000 nv_disable=1 -f -x -v to copy the kernel patch from the UniBeast stick over to the Yosemite SSD
• I then booted from the UniBeast stick to my Yosemite SSD using npci=0x2000 nv_disable=1 -f -x -v again
• I installed the appropriate Nvidia Web driver (10.10.5 (14F27) 346.02.03f01) for my GTX 980 Ti and after rebooting using npci=0x2000 nvda_drv=1 -f -x -v to the Yosemite SSD I could confirm that the card was recognized in the "About this mac" overview

• I didn't copy over my installation to an MBR formatted drive as I read somewhere that the ASUS X99-A motherboards were capable of booting from GUID
• I then did the post install using MultiBeast with the following settings:

• DSDT Free (Sets a lot of settings, didn't change them)
• Drivers Disk - 3rd party sata / intel generic AHCI Sata / Trim Enabler 10.10.x
• Drivers Misc - USB 3.0 Generic / Voodoo TSync 6 core (For it to detect all 6 cores)
• Drivers Network - AppleIntelE1000e (latest version, not sure which one exactly)

I also deleted IOBluetoothfamily.kext because I couldn't boot at all without deleting it.

Please let me know if you have any tips.
Thanks!!

I found program Chameleon Wizard be helpful

Thanks for your reply.

Although, I have completely different hardware so I'm not sure it will be very helpful.
