GeForce 550 TI Mavericks - maybe?

[ASivins]

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.

 

[ASivins]

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?

[ASivins]

There is an option, and it is disabled.

Same error.

Delete GenericUSBXCHI.

 

[ASivins]

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