Original keyboard needed when resetting PRAM ?

[madmin]

I need to do a PRAM reset on a white iMac (early 2006) which has always worked perfectly (other than the OD). I've followed the usual procedure but it wont accept the cmd-opt-p-r key combination. I've heard that this only works when using the original Apple keyboard, which I don't have. Maybe I'll have to take it to the local Apple Store for help, but would like confirmation of this restriction before doing so. Thanks in advance.

PS: the non-original k/b is an Apple Model no: A1243 circa 2007

Thanks for your suggestion but unfortunately that doesn't work. It's not a wireless keyboard. I tried waiting for the chime etc but still no luck.

For anyone else who finds themselves in this situation:

The original keyboard is needed to do a PRAM reset on this model. The aluminium keyboards that many people now use don't have the required firmware.

I took it to the local Apple Store, they confirmed and reset the PRAM for me

I didn't think keyboards had firmware.
