    When I set up my Mac Pro I created an alternate, internal drive that could also be used as a startup drive. I realize that I forget some of the keyboard commands for diagnostic startups, and recognize the inability to research them in crisis when a computer fails to work correctly.

    I am wondering how some of you may have prepared for such a possibility. Do you create any sort of references on paper?

    I also consider this as I ponder whether to create an alternate drive so I can try Mountain Lion and at the same time keep a drive with Snow Leopard in case I want to go back.

    Thoughts?

    I guess you could jot down notes if your Mac Pro is the only internet capable device in your house. When I do upgrades on my computer I use my ipad to access online DIY guides.

    Well, if the Mac won't boot from your primary startup volume, just do this:
    - Reboot
    - As soon as you hear the startup sound, hold down the option key and KEEP HOLDING IT DOWN
    - In a few moments the startup manager will appear, giving you a choice between all bootable volumes
    - Select your alternate boot volume and go...
