Forcing 64Bit Mode from boot.plist (10.6.3)

[insanely2010]

i've a 10.6.3 snow on Vbox usign 10.3 legacy kernel on AMD CPU

 

on my boot.list i have:

 

	<key>Kernel</key>
<string>legacy_kernel</string>
<key>Kernel Flags</key>
<string>arch=i386</string>

 

normally if i want to boot on 64bit mode, i've just to digit using keyboard "-force64" on chamaleon boot selection

(on system profiler 64-bit kernel and expansions display a : NO, but Activity-Monitor display a: INTEL 64-BIT for all processes and system seems to run 20% faster looking some benchmarks)

 

today i tried to change the boot.plist to automatically run osx on 64bit mode

 

	<key>Kernel Flags</key>
<string>-force64</string>

 

and

 

	
 <string>force64</string>
 <string>arch=x86_64</string>
 <string>arch=i386 -force64</string>

 

but 64bit mode don't start... ( on last column of Activity Monitor there is just: INTEL )

 

someone may suggest me a correct string for the boot.plist? thx!

after 2 ours i solved this...

 

i placed the

 

<key>Kernel</key>
 <string>legacy_kernel</string>
 <key>Kernel Flags</key>
 <string>-force64</string>

 

on boot.plist (com.apple.Boot.plist file) placed on /library/preferences/systemconfiguration

 

and removed from the boot.plist on /extra folder

 

that now only have the "Graphics Mode" "1360x768x32" string and the "Timeout" "1" string

and works....

 

2 different Boot.plist 1 for the kernel, and 1 for Virtualbox VGA resolution + Chamaleon Timer (???)

 

Well, now i' ve a "new" issue... on "GET INFO" window in don't have the "32 Bit Mode" compatbility option, and i can't run some 32bit executables.

 

Any idea for this new trouble?
