As of the release of 10.6.8, all Sandy Bridge systems can now use the default iBoot + MultiBeast Method. This guide is now defunct.

What you need: -Mac OS X Snow Leopard Retail DVD -iBoot 3.0 or newer -MultiBeast 3.5 or newer -10.6.7 Combo Update -BridgeHelper Installation: 1. Follow all Tips & Recommendations 2. Install using iBoot + Retail DVD 3. Boot with iBoot 4. Set up Computer 5. Run Combo Update - DON’T REBOOT 6. Run MultiBeast with UserDSDT + System Utilities* 7. Run BridgeHelper 8. Reboot from hard drive *If you have a fixed DSDT.aml, place it on the desktop before step 6. If you do NOT have a DSDT.aml, install NullCPUPowerManagement.kext in addition to UserDSDT. Post Installation Audio If using Realtek ALC8xx Audio Codec: Install ALC8xxHDA + AppleHDA Rollback + HDAEnabler for your specific codec. All others use VoodooHDA. NVIDIA Graphics If using NVIDIA 4xx "Fermi" card, you must install tonymacx86 NVIDIA Update after Combo Update. ATI Graphics If using ATI 5xxx/6xxx supported cards, you can have native ATI injection or use the default GraphicsEnabler=Yes. To test, install the ATI 220.127.116.11 Drivers via MultiBeast.
