Dell XPS 8900 - upgrade from El Capitan to Sierra

[Jedis]

Hello,

I have a perfect working El Capitan install. I downloaded the Sierra installer from the App Store. When the installer tries to boot, it kernel panics.

The system has a Skylake processor with Nvidia 960 graphics card and Intel 530. I tried booting with nvdisable=1 without success. Tried safe mode also without any luck. It's complaining about the AppleIntelFramebuffer. Any suggestions?

I tried deleting my kext cache and upgraded Clover to the latest. My standard boot args for El Capitan are: dart=0 darkwake=10 nvda_drv=1 HaltEnabler

I've tried -v -x nv_disable=1
Also tried using Clover to InjectIntel and setting the platform id to 0x19120000

DVMT Pre-Allocated setting in BIOS is likely set incorrectly. Required: 64mb or larger.

I saw that and looked in my BIOS, but I don't see that as an option to change.

You can either raise the DVMT value in the UEFI BIOS settings to at least 64MB, or you can use the minStolenSize patch and see if that gets around it.
