GeForce 550 TI Mavericks - maybe?

Hey, I'm super stumped.

System Stats:
ASRock z77 Extreme4
i7 3770 3.4gH
2xGeForce 550 TI 1G

Ok, so I followed the this guide - http://www.tonymacx86.com/mavericks...talling-mavericks-asrock-z77-extreme-4-a.html

the OS loaded as it should have. loaded the Ethernet drivers, rebooted, worked fine. ran MultiBeast, and this is where the issues started. I initially stated off with a panic error on the CPU. I removed the AppleIntelCPUPowerManagement && AppleIntelCPUPowerManagementClient KEXT files. Removed the first set of panics.

This started a new set of Debugger errors. I re-installed after the first time I loaded because I got the same error and thought I might have taken a wrong turn. Might not be the case.

I can no longer load into OSx normally or in safe mode. I get a debugger error that reads something like (image attached):


Debugger Called: </SourceCache/GPUDriversIntel/GPUDriversIntel-8.18.29/Common/IONDRV/Intel/IRV/AppleIntelFramebuffer/AppleIntelController.cpp:13701 Assertion failed: (0 == i ) || ((pfbInfo->rangeSolution.physBase - pfbInfoPrev->rangeSt


Anyone have any idea? Is it because I have two cards in? the ( 0 == i ) looks reminiscent of a for loop that might be tossing an error?

I've tried:
GraphicsEnabler=Yes/No
IGPEnabler=Yes/No
dart=0
UseKernelCache=No
-x

I feel like the load is really close to being good, but I'm getting stuck. kinda getting frustrated.

Have you flashed a custom BIOS for you board?

in BIOS torn off internal graphics chip then try and boot with npci=0x2000 -v -f
-f is mandatory now that from your log it seems like a kernel cache issue.

Yes, I flashed from 2.2 to 2.9.

The on board graphics are disabled.

Tried :
npci=0x2000 -v -f
UseKernelCache=No -v

Same error.

Do you have an option in UEFI/BIOS to disable VT-d?

There is an option, and it is disabled.

Delete GenericUSBXCHI.

Same error. but now rather then printing before the end error "Failed to load GenericUSBXCHI" it reads "Failed to load AppleUSBXCHI"
