Setting Automatic Kernel Options

[Stern]

For my computer not to have problems with lag, i have to explicitly add the kernel option "platform=X86PC" every time I boot. Is it possible to make a change to the kernel or some other file so that this is automatically chosen as the platform?

yes, you have to exit the com.apple.boot.plist (I don't remember where it is) but you have to copy it out of the dir, edit it and then SUDO cp it back in over the original.

eh... just sudo -s in console

then go to /Library/Preferences/SystemConfiguration/

then use your editor to edit com.apple.Boot.plist

i use pico, so i do

 

pico com.apple.Boot.plist

 

then add in

 

<key>Kernel Flags</key>

<string>platform=X86PC</key>

 

hope that works as its coming from my memory, but I'm pretty sure its correct.

for anyone who is reading this, i found how out how to do this. navigate in terminal to /Libraries/Preferences/? (forget the name of the folder). type in sudo pico com.apple.Boot.plist, and enter your user password. go to the section where it says <key>Kernel Flags</key>. underneath should be <string></string>. enter what you want to automatically be set during boot (platform=X86PC, "Graphics Mode", etc.).

I'm pretty much a Unix newbie and don't know much about command line stuff.

So can anyone please tell me how to exit Terminal when having changed com.apple.Boot.plist? I used the sudo pico command and don't know how to apply the changes. Sorry for this newbie question, anyway I'd like to get a quick answer.

 

Thx,

EDIT:

OK guys, I found a tutorial on how to use nano, so there should be no need for help for now.
