I have OS 10.6 installed and working and windows XP also installed and working. If I hit any key as the computer starts I can access the Chameleon GUI and select either OS. However OSX is default.
Going to the com.apple.Boot.plist per the help file from the Chameleon GUI located in /Library/Preferences/SystemConfiguration/com.apple.Boot.plist I added two lines
I hit tab to verify the 0,2 values but it still goes to OSX by default, I have also tried "Instant Menu" and that also did not seem to change any of its boot behavior.
