Permanent Boot Options?

[MadMax08]

Hey all,

 

after HOURS of tweaking, i finally got 10.5.1 up and running, on with "tohkernel" and "cpus=1" in my boot options. is there a way to make those options permanent so i dont have to enter them every time i turn on my computer?

MadMax,

 

Go to: /Library/Preferences/SystemConfiguration

 

Open up com.apple.Boot.plist in TextEdit.

 

Change:

 

	<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string></string>

 

to:

 

	<key>Kernel</key>
<string>tohkernel</string> (Also - I don't know if that's the kernel flag you use, enter the tohkernel flag between the <string>'s)
<key>Kernel Flags</key>
<string>cpus=1</string>

 

Then save the file, and reboot! Also, if that doesn't work - just go in single user mode (-s) - and edit the file to say:

 

	<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>tohkernel cpus=1</string>

You're very welcome. Hopefully this works, I haven't tried it since the 10.4 days - but as I recall, it should be exactly how to do it. The only thing I was afraid of though is just the kernel flag, because I had to use platform=X86PC when booting Tiger, so I only used the one string. So, let me know how it goes!
