When I boot Mac OS X darwin automatically boots but I wanna choose which operating system to use so I wanna have an countdown before it starts to load the default OS.

Does any one knows how to increase this?

Exactly the same problem here. Not only is the time to press f8 too short, it'd be much better if it were automatic.

So I'd like the menu to choose to OS appear automatically (which normally appears manually when f8 is pressed).

Anyone know how?

Set the Timeout parameter in boot.plist: http://forum.insanelymac.com/index.php?act...st&p=243116
