I fixed my problem with this:

simply great

by the way I noticed that any changes I make in the com.apple.boot.list file in /Library/Preferences/SystemConfiguration don't work.. dunno why.. for example I added the timeout string but in chameleon still no timeout! I tried also copying the plist file in /Extra but still no luck.. I can not customize the chameleon boot very strange any ideas?

bye!
