macmatt79 Posted September 7, 2009 Share Posted September 7, 2009 How do I get SL to boot into 32bit mode? I have it installed but cant get my sound or lan to work on my P43-ES3G motherboard with 8111C LAN. SL keeps booting into 64 bit mode and I tried to hold down 32 while booting and this does not work. I think the reason my sound and LAN don't work is due to their not being any 64bit Kexts available. I am using Chameleon R2 as my bootloader via a USB flash drive per Lifehackers method. Any Ideas on where I should start?

sunkid Posted September 7, 2009 Share Posted September 7, 2009 Use -x32 as a kernel flag when booting. You can put this into your com.apple.Boot.plist: <key>Kernel Flags</key> <string>-x32</string> Link to comment Share on other sites More sharing options...
kamikaze Posted September 7, 2009 Share Posted September 7, 2009 For some reasons the flag doesn't change anything... I can still see that kext are 64 bits Actually that brings an interesting question, how do yo know if you kernel is 32 or 64? I figure it out by checking the kext type in About my Mac...

kamikaze Posted September 7, 2009 Share Posted September 7, 2009 System Profiler -> Software Thanks, I figured but wanted confirmation. So.. I am kind of trapped in 64 bits mode. Let me summarize my install: Chameleon RC3 + EFI Partition. boom.plist on EFI partition with flags -x32 -v -arch=i368 Still.. it boots 64 bits !!

Jingu Posted September 7, 2009 Share Posted September 7, 2009 You're not the only one, Since using Chameleon RC3, it doesn't read the 32-bit kernel flags. It always boots 64-bit. What I do is when the chameleon GUI shows up, I hit Tab, that brings me to the Darwin bootloader. From there, I select the Snow Leopard partition and type at the promt arch=i386. That gets me to boot in 32-bit. Link to comment Share on other sites More sharing options...

coolio2004 Posted September 8, 2009 Share Posted September 8, 2009 I have permanent 32 bit booting with boot argument arch=i386 -x32 and not -arch=i386 -x32 plist. with RC3. Link to comment Share on other sites More sharing options...
rosumella Posted September 9, 2009 Share Posted September 9, 2009 I have permanent 32 bit booting with boot argument arch=i386 -x32 and not -arch=i386 -x32 plist. with RC3. So you put both flags arch=i386 and -x32 in com.apple.Boot.plist? Link to comment Share on other sites More sharing options...
imacken Posted September 21, 2009 Share Posted September 21, 2009 So you put both flags arch=i386 and -x32 in com.apple.Boot.plist? For RC3, you just put arch=i386. Link to comment Share on other sites More sharing options...
d-track Posted April 1, 2010 Share Posted April 1, 2010 For RC3, you just put arch=i386. i am in the same boat. snow leo 10.6.3 installed with chameleon 2 rc4 i cant find any com.apple.Boot.plist file on my hdd not even with hidden files enabled where is that? should i create one?
