Stork's Sandy Bridge Z68X-UD3H - i7-2600K - HD3000 - MtLion
jiteshpatel,
I'm still running Lion on Zorro. I'll upgrade to Mountain Lion probably in June. That being said, using Son-of-Zorro's 10.8.3, MultiBeast configuration as a Guide, here's how I would do a fresh install of 10.8.3 on Zorro, following the UniBeast Installation Guide and the MultiBeast configuration.
After installing 10.8.3 and downloading the Z68X-UD3H F12 DSDT from the tonymacx86 DSDT Database, put the DSDT on the desktop, naming it DSDT.aml. Then, run MultiBeast v5.2.1 with the configuration below.
Note 1: I'm using the default System Definition MacPro3,1 for this configuration since you probably have only one monitor; if you are using HD3000 with two monitors, use the Customization > Systems Definition > Mac Mini > Mac Mini 5,1.
Note 2: See page 3 of the MultiBeast Features document that comes with MultiBeast to see the default loading for the "UserDSDT or DSDT-Free Installation" selection.
Note 3: I am not overclocking, so I choose the non overclocking i7 SSDT.
Before rebooting, download the latest version of Chimera (v2.01 at the time of this post) and install it so you can use iMessage, if you desire, and other enhancements. (The next update of MultiBeast will have Chimera v2.01 as the default bootloader.) Now reboot using your drive to boot from instead of your UniBeast USB thumb drive.
