Need Help! Intel WorkStation S5520SC and 2 Xeon x5960 build

[otaciliomaster]

Hi guys i need some help. I managed to install Moutain Lion 10.8.4 on this system using PCIRootUID=0 boot flag, but when i run multibeast on it, i got KP. I don't need audio and network drivers, cause there no drivers for this board. Anyone can help?

My System:
Intel WorkStation S5520SC
Dual Xeon X5690
32gb 1333 Ram
Nvidia Quadro 4000

install nullcpumanagement kext in multibeast to fix the kp. later if u r able to patch your bios u can remove it.run dpcimanager click on misc then on autopatch if successfull then remove nullcpumanagement kext from system/library/extensions then run kext utility and reboot.

 

[stehor]

download dpcimanager from this site open it and select misc click on autopatch if successfull then remove nullcpumanagement kext from system/library/extensions get kext utility from downloads run it and reboot done

your mobo doesnt have native power management so u need to do a fresh install with easybeast

bump...

Count me in, I have a S5520HC also and am working on completing my new daily driver. Almost all basics are working after unibeast install (no multibeast yet, still experimenting on cloned partition). If anyone has this working and completed I would be extremely grateful for any advice you may have.

Working:
Processor: Xeon E5620
Motherboard: Intel S5520HC
Sound: turtle beach micro - usb
Video: dual monitors on an nvidia 640gt
bluetooth: using an old kensington usb for magic mouse and apple bt kb
HD: SATA hotplug via antec drive bay

To do items:
embeded nic's
power states on cpu
boot (still using unibeast usb for boot)
adaptec raid controller
possible creation of user dsdt (will be my first so....)
