Open Firmware & Resetting NVRAM
(similar but not exactly the same as resetting PRAM)
Note: the Intel-based Macs do not use Open Firmware. The following instructions only work for PowerPC-based Macs (G3, G4, G5).
Boot computer into Open Firmware by holding down Option-Command-o-f keys (o and f for open firmware) immediately after powering computer up.
At the Open Firmware prompt, type:
reset-nvram
Press Return.
Next, type:
reset-all
Press Return.
Some text will display and computer will restart.
Other useful Open Firmware commands include:
shut-down
mac-boot
eject cd
