P8Z68V-Pro Gen 1 El Capitan install help needed

[ebm]

Hi All!

I've had every version of OS X working upto Yosemite with very little issues (usb 3).

Having issues getting El Capitan working. I refreshed the MOD BIOS 3603 and Yosemite installs fine but no-go with El Capitan.
If anyone has this board could you please post your Bios Settings.

I have a Nvidia GT220 PCI card. I've tried all the following alone and various combinations (even all at once).
nv_disable=1
GraphicsEnabler=Yes (works with Yosemite or else will not boot)
PCIRootUID=0
-v
-x
-f

SMBios
iMac12,1
iMac12,2
Mac13,1 etc.
Mac3,1

I re-downloaded the latest El Capitan and the 6.1.1 unibeast and created two 16 gb key's. One Vanilla and the other with Nvidia injection. Both boot to Clover but I can't get the installer going.

Sometimes I get a bunch of ++++++++++++++++
Other times it reboots quickly so I can't see what it's failing on.

Any help greatly appreiciated!

Will give it a shot when I get home.

Thank you!

That did the trick.

I was able to get it installed.

I'm only able to boot into it with those commands and get only 1024x768 with slow graphic tearing but I can now play with various flags and bios settings.

Thank you again!

As have an ASUS mobo you will have either to patch the BIOS with PMPatch or add nullcpupowermanagement.kext to your EFI/CLOVER/kext/10.11 folder on the EFI partition you boot on.
Use Clover configurator to mount EFI and easily change settings
