SL boots in 64-bit when using the Chameleon or PCEFI bootloaders.
If you wish to boot in 32-bit mode, you will have to add one of the following flags in your customized com.apple.Boot.plist in the Extra Folder:
-x32 (when using PCEFI)
arch=i386 (when using Chameleon RC3)
My com.apple.Boot.plist in the Extra Folder looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "
http://www.apple.com...yList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>-x32</string>
<key>device-properties</key>
This is very important if using Nvidia 7xxx cards or lower because the system will Panic in 64 bit mode, if using Nvidia 8xxx or higher Booting in 64 bit will work just fine.
