At first I thought you meant PS/2, but it seems you meant PS2 or PS3. Keyboards (including the smaller pads) are worth a look from the gaming side. This PS3 one works as both a keyboard and mouse over Bluetooth, though paring is a little odd and may need special drivers. Mouse wise, the chat pad has a toggle between keyboard and mouse. When mouse mode is activated, the entire keyboard surface turns into a touchpad for mousing. It's not the most precise experience but could work for a media system.


The Logitech Bluetooth keyboards and mice I've seen/used in the past come with their own USB Bluetooth dongle. If the keyboard and mouse is paired to it, it works for BIOS setup and OS setup. It does this by handling all the Bluetooth side inside the dongle, then telling the machine a generic USB keyboard and mouse is attached. Later on when the OS is fully booted and loads bluetooth drivers, control is handed over from the dongle to the drivers. Some integrated Bluetooth controllers will do the same, including the ones Apple uses in their computers.
