I have recently installed Jas 10.4.9 and it is running without any problems other than the front side bus speed which is set to 200 by default.

I can change it at darwin boot loader by typing in fsb=266 but what i need to do is have it changed automatically by setting the speed in com.apple.boot.plist.

Here lies the problem. No matter how I enter the details it refuses to change.

I would much appreciate it if some one could give me details of exactly how it needs to be entered or alternatively is there a 10.4.9 kernel out there that will auto detect the fsb speed to save me typing it in every time i have to reboot
