So I have a motherboard with an annoying feature that if there is not a keyboard connected, it refuses to boot and there is no option in BIOS to disable this feature. Having to always have a PS/2 keyboard plugging into it is really annoying since I'm usually just accessing via network. I thought a fun project would be a dummy keyboard that's just a little dongle that plugs into the PS/2 port:

I think the only way to make it smaller would be to skip the PCB and manually solder it to the legs of the PS/2 connector.

And what's this? Why does it have an F1? Because it's actually a real keyboard with just one key, for when BIOS decides to complain about the previous boot being incomplete and needs you to press F1 to continue 😀 I have a few extra if people are interested, I can put them up somewhere for people to find.
