Guest bikedude880 Posted November 10, 2006 Share Posted November 10, 2006 Save it to your desktop, then drag it from your desktop to the correct folder. Link to comment Share on other sites More sharing options...
Rammjet Posted November 10, 2006 Share Posted November 10, 2006 You can edit the file by dragging it to the Desktop and editing it with TextEdit, then dragging it back, answering the 2 resulting dialogs - Authenticate and yes to replace, then followed by using Disk Utility to repair permissions on the OSX partition. Or you can do it via Terminal with this command: sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist Link to comment Share on other sites More sharing options...
Soündless Posted November 10, 2006 Author Share Posted November 10, 2006 how do you do idlehalt flag? can you rig it into the boot.plist? Link to comment Share on other sites More sharing options...
Rammjet Posted November 10, 2006 Share Posted November 10, 2006 just put idlehalt=0 in the Kernel Flags parameter Link to comment Share on other sites More sharing options...

Jagojon3 Posted November 10, 2006 Share Posted November 10, 2006 Didn't work, said the folder "System Configuration" could not be modified Link to comment Share on other sites More sharing options...
Rammjet Posted November 10, 2006 Share Posted November 10, 2006 what? Remember at the top of this thread where you added cpus=1 to the Kernel Flags parameter in boot.plist? Well, you put idlehalt=0 in the same line where you put cpus=1. In fact, any boot parameter that you use can go into the Kernel Flags parameter. Didn't work, said the folder "System Configuration" could not be modified Which method did you use? Dragging the file back to the folder or the nano command from Terminal? As I said above, when you drag the file back to the folder, you are going to get 2 dialogs: one is going to say you can't do that. Just click the Authenticate button and enter your password. The other dialog is going to ask if you want to replace the existing file. Just click yes. Link to comment Share on other sites More sharing options...

I just got audio working and i dont wanna screw it up A "red underliney thing" in TextEdit? That is TextEdit checking your spelling. It doesn't know how to spell Idlehalt and is flagging it as a possible misspelled word. Has nothing to do with the right parameter. Link to comment Share on other sites More sharing options...

Now I just need to figure out how to shorten the countdown on the Darwin bootloader... edit: it didin't work, I'm still running in dual core mode...

Rammjet Posted November 10, 2006 Share Posted November 10, 2006 Now I just need to figure out how to shorten the countdown on the Darwin bootloader... Go back into your favorite boot.plist file and change the number under the Timeout parameter. It is the number of seconds. Link to comment Share on other sites More sharing options...
Soündless Posted November 10, 2006 Author Share Posted November 10, 2006 Ok, that didnt work, i set my boot.plist back to cpus=1 so my mouse works. what do you think is wrong? i have a Pentium D 930 3ghz if that is any help the way that i did it was, i clicked get info on the boot.plist and allowed myself to read and write. i did the same thing to the folder it is in Link to comment Share on other sites More sharing options...
Rammjet Posted November 10, 2006 Share Posted November 10, 2006 Ok, that didnt work, i set my boot.plist back to cpus=1 so my mouse works. You didn't have to remove cpus=1. You just add the other parameters beside one another. <string>-v -f -x cpus=1 idlehalt=0 fn=3 fsb=166 -nohpet, -legacy</string> Link to comment Share on other sites More sharing options...

Jagojon3 Posted November 10, 2006 Share Posted November 10, 2006 Every time I try to rename my ....Boot.plist that I have saved on my desktop it adds a .txt to it and I can't save it to the correct place and overwrite. How do I stop it from adding the txt to the filename? Link to comment Share on other sites More sharing options...
Rammjet Posted November 10, 2006 Share Posted November 10, 2006 can i set cpus=2? If you have dual cores, setting cpus=2 is unnecessary because the OS will try to use both cores. But if the OS has problems when it uses both cores, then you need to tell it to use only one of them via cpus=1. You can use cpus=2, but as I said, it really is superfluous. Every time I try to rename my ....Boot.plist that I have saved on my desktop it adds a .txt to it and I can't save it to the correct place and overwrite. How do I stop it from adding the txt to the filename? Click on the boot.plist icon on the Desktop. Hit your Enter key. Remove the .txt suffix. OSX will ask if you really want to do that. Select the plist suffix in the dialog. Link to comment Share on other sites More sharing options...
