Snow Leopard wont't boot from hard drive, but successful installation (help please)

[MigGat]

Hi everyone. I managed to install Sqnow Leopard from a retail dvd, using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]-ATI (from tonymac's) and with a lot (really, a LOT) o tries, got my graphics card working just fine (Radeon HD 5750).

 

However, i can only boot from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]-ATI cd :S

 

I tried many options in [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] but none worked.

 

Any idea what might be happening? I keep gettin this message:

 

ACPI_SMC_PlatformPlugin::start - waitForService(resourceMatching(AppleIntelCPUPowerManagement) timed out

 

...and wait forever..

 

 

Thanks in advance

 

BTW, this is my hardware:

Processor: Intel™ Core i7 860 2.80GHz

RAM: 2 x Kingston 2GB DDR3-1333
