Spursboy Liv Posted June 13, 2008 Share Posted June 13, 2008 Hi there, basically I was wondering if there was a way that you can change the default kernel Leopard boots up with, as currently I'm dual booting my Kalyway 10.5.2 system with Windows XP Professional. I want to use either the "sleepkernel" or the "speedstepkernel" as default as they are the only 2 that work for my configuration (I'm using an AMD Athlon 64 3500+ CPU which doesn't support SSE3). Stupidly of me, I accidentally selected the "modbinkernel" when I was installing Kalyway 10.5.2 along with the other 2 (sleep and speedstep), and by default it boots with the modbinkernel, which never works as it is an SS3 kernel :censored2:, so if there is a way of changing it then it would be greatly appreciated, as I'm reluctant to reinstall it all over again, and it gets tedious after a while by having to always type in sleepkernel or speedkernel at the boot options in the Darwin/x86 Bootloader. Thanks in advance. Kind regards, Livio. Link to comment https://www.insanelymac.com/forum/topic/110351-changing-default-kernel/ Share on other sites More sharing options...
riws Posted June 13, 2008 Share Posted June 13, 2008 In Terminal: sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist <key>Kernel</key> <string>mach_kernel</string> And change mach_kernel to sleepkernel And save it (Control-X) Link to comment https://www.insanelymac.com/forum/topic/110351-changing-default-kernel/#findComment-781841 Share on other sites More sharing options...
Spursboy Liv Posted June 13, 2008 Author Share Posted June 13, 2008 Okay thank you very much, I will try it out later UPDATE: It's all working now thanks to your solution - boots flawlessly into sleepkernel and no more tedious typing thank you once again!
