No the CUDA switch is a button. Don't go jumpering unknown wires (not
that you planned to I am sure). I just popped the top on an LC 2, no
switch. So there may not be one on the 476 either, I would verify, but
both my 475's are in use at another location.

There is no ALT on the Mac. Some keyboards have "Alt" inked above
"Option" on the OPTION key, because Apple wanted compatibility with PCs,
but in all cases, it is "Option" when talking Mac-speak.
So you would press Command-Option-P-R. Hold these down right after
hearing the startup bong, and continue to hold them until you hear the
Mac bong again. It is recommended that you do this until it bongs 3 times
total (just keep holding them down). I don't know exactly why, but that
is what Apple's TIL suggests.
In the event you are doing this on a soft-power Mac, (and more
specifically a PowerBook), rather than going BONG and starting the boot
again, the Mac may go BONG and then turn off. That is normal behavior on
most PowerBooks most of the time, and occasionally on soft power Macs
(ones that don't have a physical power switch, but rather you have to use
the Power Key on the keyboard... the 476 is NOT one of them).
