How do i install and change kernel?

[scober]

Hi,

 

I downloaded two different osx86 releases and finally got iDeneb to work with a new ethernet card.

All works - Audio, Video, Network, USB - except it says it's a single core cpu.

 

The processor is an Athlon 64x2 3800+

The other version of osx86 I downloaded - Kalyway i think - gave me both cores in the system settings.

 

How do I install a different kernel to see if I can get both cores working?

And if this messes up, how do go back to the original kernel i'm using?

 

Thanks.

 

[EDIT]

OK - after *actually searching* a bit more i found someone trying the following:

 

At boot try - cpus=2 - if this works then -

Open /Library/Preferences/SystemConfiguration/apple.boot.plist (something like that)

under kernel flags you just put the cpus=2 and you are done

 

I'll try that when I get home after work.
