The disk on my PowerBook G4 is going bad. This is a Bad Thing, but at least I learned how to do some cool things with my Mac at boot time. I’ve checked all these on my system running Mac OSX 10.3 (Panther). I found many other keys that might work, but I haven’t verified anything except what’s listed below:
Booting from CD — hold down the “C” key (until the Apple logo appears) while powering on the laptop. Insert a bootable CD as soon as the power is on.
Booting as a FireWire “target” — connect the PowerBook to another FW-equipped system. hold down the “T” key (until FW symbool appears) while powering on the laptop.
Choosing boot device — hold down the Option key (until the Apple logo appears) while powering on the laptop. You’ll see an icon for each bootable device (hard disk, bootable CD, network, etc). Select one of the icons, then click on the right-arrow icon.
Booting single-user — hold down the “Command-S” keys (until the Apple logo appears) while powering on the laptop.
Added 2005-12-19: Hold down the mouse button while powering on — eject CD-ROM.
