Hi,

 

I have MAC OS X 10.6.3 Snow Leopard, and I'm using it with a 64bit processor. How do I set it to always boot as 32bit so I won't need to input the command "arch=i386" ?

Thank you in advance.

I don't understand what i'm doing wrong here:

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>arch=i386</string>
<key>Boot Graphics</key>
<string>Yes</string>
	<key>Quiet Boot</key>
	<string>No</string>
	<key>Timeout</key>
	<string>5</string>
<key>arch</key>
<string>i386</string>
</dict>
</plist>

 

After modifying the file, if I don't input the "arch=i386" boot command it will boot as 64bits.

Any suggestions?

The com.apple.boot.plist may be in Macintosh HD/Extra/ or Macintosh HD/Library/Preferences/SystemConfiguration/ edit both of them. Copy the file to the desktop, edit in TextEdit and replace the original. Reboot.

chameleon looks first at the Extra

 

if not find anything on Extra, the chameleon can read in the library/preferences/SystemConfiguration/com.apple.boot.plist

 

already given in these two locations?

If you don't know what he meant by that then don't worry about it.

 

If you're curious, open Terminal and type Diskutil List at the prompt.

 

If you see a hidden ~200 MB partition on your OS X drive then that's what he meant. Some of us install the bootloader and all the support files to that partition. If you didn't put anything there yourself then it's probably empty.

 

But if you used an installer when installing the bootloader and blindly changed the install options without knowing what you were doing, then maybe your files are on that partition.

 

Go here for more information (install instructions are for 10.5.x though):

oh... I understand now... still... any idea why it is booting as 64bits with the arch=i386 boot flag ?

it's not a big deal to input the arch=i386 but i'm just curious how to fix it, maybe i'm not the first person which is confronting with this problem and for sure i'm not the last so... how can we fix this ?

Maybe you have Netkas' PC-EFI bootloader and not Chameleon. It uses -x32 instead of arch=i386 to boot in 32-bit mode.

 

No, because if I type "arch=i386" before booting, it will boot under the 32bit. But I want to make this automatically, so it will boot under 32bits without me inputing the arch=i386.
