No keyboard on startup Mini?

hello
I recently purchased a Mac Mini Core duo 1.83ghz to use as mediaplayer in my living room.
I noticed that i wasn't able to use any keys during startup, trying to reset the PRAM. Later on, when i replaced the standard 80gb harddrive with a bigger one and trying to use the "C" during startup, i found out t that i can't use any key during startup. I learned that a firmware-password blocks all keys during startup, except alt-option-f-o to enter the open firmware but i can't even enter the open firmware during startup. The mini simply doesn't respond to any key i try to use on startup. Once booted, the keyboard and mouse work both fine in Snow leopard.
What can be wrong with my mini?

Exactly, precisely, and including all relevant model numbers, etc., what keyboard are you using with your Mac Mini?

And - you can't enter Open Firmware on a Core Duo mini, because your mini doesn't have Open Firmware. That's only for PPC Macs.

If you try other boots, like the C to boot to a DVD, and you get a simple password screen instead, then there's nothing wrong with your mini. You just need to clear that firmware password. The previous owner should know what that is.
Or, failing that, there is another method to clear that firmware password. You should be able to google for that.

If you're using a Bluetooth keyboard with a Mac Mini of "Core Duo" vintage, then the Mac can't read from the keyboard at boot. The Mac was designed before they made the BT keyboards.

It's a A1176 Mac mini core duo 1.83 (Mac mini 1.1)
I use a Apple wired aluminium USB keyboard (A1243)

I don't get a password screen. To be sure i cleared the firmware password using the Snow Leopard DVD. This doesn't seem to help, still no keys at startup.

Could it be that the keyboard is too new (or my mini is too old) for this Mac mini?

How did you boot your mini to that Snow Leopard DVD, if none of your keyboard startup keys work?

I changed the startup disc in the system preferences.

Run software update, to see if there's a keyboard update offered.

Does your mini work with a different USB keyboard?
