Dongles to Fake Presence of a Keyboard?

An anonymous reader asks: "I have a Compaq IPAQ desktop system (legacy free) that will not boot headless. (Yes I did try to tell the BIOS to not generate a no keyboard error, but there is no such setting for the BIOS of this system.) Since I would like to use it such and don't wish to waste a keyboard just to keep it from complaining, I'd like to come up with a small dongle that would fake the system into thinking that there is a keyboard attached. This is the same basic thing that KVM's do, so the circuit shouldn't be that difficult to find. Has anyone heard of such a thing? Can anyone provide or point to somewhere where I can find the basic circuit for this?" How hard would it be to take the connector part from a old non-working keyboard and wiring something like this up?

Keyboard Emulator cheap

Get one of these super cheap keyboards. A few screws hold this together and the intenals are just printed on plastic sheets. The PCB with the controller is about 2" x 3". Wrap it in electrical tape and just stick it to the back ot the case (or hide it inside). One warning, these keyboards suck, so don't try to actually type on them.
