Couple more questions from a Mac newbie

[passthejonch]

How do I boot from OS 9 on my new iBook?

How do I save a screenshot of my desktop as a jpeg?

Oh yea and i put the mouse sensitivity of my computer on max... but its still too slow is there anyway i can up this?

Go to preferences and select Mac OS Z1-9.2.1 etc and click restart.
Click lock on the bottom if u want this to be ur default selection.
If you dont want to restart as 9x, u can still call 9x to run under OSX, it's in prefereces : classic

To grab a screen shot go to: finder and select Grab> Screen
Or simply by pressing Command+SHift+3
then just paste it in any picture editing program (photoshop etc)

Cheers
