Dave Polaschek used to be a programmer at Apple, so I assume that he knows lots of little tidbits unknown to the rest of us who have never been privy to the of the secret innards of Apple.


 

On Boot

Key Combination Effect
mouse down Eject removable media ( I think Boot ROMs prior to 2.4f1 excluded the CD drive )
opt Bring up OF system picker on New World machines - boot to 9 on pre-New World machines
cmd-period When OF system picker is active, open the CD tray
cmd-opt Hold down until 2nd chime, will boot into Mac OS 9 ?
cmd-x (or just x?) Will boot into Mac OS X if 9 and X are on the same partition and that's the partition you're booting from.
cmd-opt-shift-delete Bypass startup drive and boot from external (or CD). This actually forces the system to NOT load the driver for the default volume, which has the side effect mentioned above. For SCSI devices it searches from highest ID to lowest for a partition with a bootable system. Not sure about IDE drives.
cmd-opt-shift-delete-# Boot from a specific SCSI ID # (# = SCSI ID number)
cmd-opt-p-r Zap PRAM. Hold down until second chime.

n Hold down until Mac logo, will attempt to boot from network server (using BOOTP or TFTP)
r Force PowerBooks to reset the screen
t Put FireWire machine into FireWire Target Disk mode
z Attempt to boot using the devalias zip from first bootable partition found
ctl-cmd-shift-power Reset power manager (with computer off)

cmd (Classic only) Boot with Virtual Memory off
space (Classic only) Trigger extension manager at boot-up
cmd-v (OS X only) show console messages during boot
cmd-s (OS X only) boot into single user mode
cmd-opt-c-i (Mac IIci only) Set date to 20 Sep 1989 to get a graphical easter egg
cmd-opt-f-x (Mac IIfx only) Set date to 19 Mar 1990 to get a graphical easter egg
cmd-opt-shift-tab-delete Erase startup disk under 7.1(?)
