Wireless Keyboard Not Recognized During Startup

I've just moved up from a mid '07 iMac to a mid '10 Core i3 iMac. I have the wireless keyboard which I think was a mistake for me. I use startup command keys quite often and it seems as if the iMac won't recognize these key-presses faithfully.

Now, after applying the 10.6.5 combo last night, the iMac will not recognize them at all. I must have tried 20 times to bring up a boot device options menu, (command key during startup). The machine just won't recognize it. I've tried other keys during startup and they're not recognized at all either.

At least before the update, I was able to get about a 1 in 3 chance of it working, which is really poor. Now, I have no success.

I did put a call into Applecare about it. I wasn't aware that a standard aluminum wired keyboard was a 'no-cost' option, otherwise I would have gone with that.

Anyone use any 'tricks' to get this keyboard to be recognized during startup?

TIA

iMac 11,2 4gb RAM, Mac OS X (10.6.5), Core i3 @ 3.06ghz

First place I'd try is do a PRAM reset, you will need to use a wired keyboard.




_PRAM RESET_

• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.
