I am trying to install OSX Leopard, which I have no experience in, and I am following this guide: http://dailyapps.net/2008/03/hack-at...windows-vista/ When I get to the boot screen and press F8, then type -v and press enter, the lines of text scroll across the screen until I get to this:

extension com.apple.driver.acpi_smc_platformplugin has immediate dependencies on both com.apple.kernel and com.apple.kpi components; use only one style.

Then it stops loading and nothing happens. Like I said I have no experience with this so I would really appreciate it if anyone could help me. Here's my specs:

MSI P31 MS-7392
Core 2 Duo E6400 2.13GHz
4GB DDR2 RAM 800MHz
Nvidia GeForce 8800GT 512MB
