Resets your PRAM, I believe.
PRAM = Parameter RAM. It stores things like date, time, and volume. It's powered by a separate battery, so the settings are not lost.

Yeah, that key combo does nothing.
Command, Option, P, R, however, resets the NVRAM (non-volatile RAM). Hold it down, wait for 3 chimes, release.

Nope, only resets the PRAM. If you want to do a full reset of the NVRAM you have to either use the CUDA reset or remove the clock battery and leave it long enough for the charge to run down (pref. overnight).

Why not do both through Open Firmware?
1. Restart your Mac holding down the Command, Option, O, and F keys. Wait a few seconds and then you will enter Open Firmware mode.
2. Type: reset-nvram
3. Press Return key (will return to you to the prompt, your nvram settings are now factory default)
4. Then type: reset-all
5. Press Return key (will reset your logic board and PRAM settings)
I'll take my cake with white icing please...
