To zap the PRAM, hold down Command-Option-P-R after the startup chime.

However, you might want to do the following. Hold down Command-Option-O-F to go into Open Firmware. Once in there, type "reset-nvram" and hit return. Once returned to the prompt, typr "reset-all", hit Return, and the Mac will reboot. Be sure to leave out the quotes on both commands. Hope this helps.

POERBOOK G4, Mac OS X (10.3.9)

Ok Yoda, I assume you are saying that starting up with extensions off didn't work!? Do you have a CD that you can boot up from? If yes, the main thing is to get the system running. Try starting up off a CD. In order to do this, you will need to hold down the "C" letter on your keyboard right after you turn the power on. Keep holding it down until the MAc recognizes the CD as a start-up disk and begins the boot up sequence.

RTT try this:

To start up into Safe Mode (to "Safe Boot"), do this:

1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).

Once booted up go to this link and follow the procedures.

If you have any software (diagnostic) such as tech tools pro (v4.1 or newer) or mechwarrior, you should be able to start up off these CD's if this doesn't work.

to clear (Zap) your PRam do this when starting up:

⌘ + Option + P + R

If you have more than 1 user on the laptop, start up and hold ⌘ + S to select single user mode.

If the issue has been that you changed or renamed a system folder your computer may not recognize your start-up disk. To fix this start up holding the option key.

A kernel panic is not the end of the machine, and yes it would be easier if you had Startup CD's, but perhaps one of these options can at least get it started. But make sure to read the article I sent you to discover the cause once you get it started.
