I think I still have an old Silicon Graphics keyboard somewhere in the garage. Built like a tank, I'm pretty sure it would still work if I had a port to connect

- dogma1138 10y agoThere aren't ports because there isn't support anymore. Intel doesn't support AT, I don't even think it supports PS/2 with most of it's chipsets. The motherboards that do come with PS/2 usually implement their chipset. Also PS/2 stopped being electrically compatible a while ago around about the same time that the combo Keyboard/Mouse PS/2 ports became available. It offers pretty low current only about 250ma so you might have issues with older AT keyboards even if the chipset is still AT command compatible.
- yuhong 10y agoThis stuff is in the Super I/O chip.
- dogma1138 10y agoSuper I/O is dead and gone for like well decades. For Intel system super I/O was eaten by the ICH which initially kept compatibility with most Super I/O functions. By ICH 6 or 7 which is around the mid 2000's most of those legacy features were all gone. By 2008-9 the ICH was also gone and replaced by the PCH which doesn't have almost any compatibility or features with the Super I/O architecture.
- speeder 10y agoWhat is the nuvoton superio chip on my ASRock z97 then?
- dogma1138 10y agoMost like the same things the rest of them do like SMBus, temperature sensors, fan control and voltage monitoring. They also do the GPIO for various other features like resetting the bios or switching between different BIOS flash chips, more recently the LED controls on the newer motherboards and the error code segment display that is now used instead of the POST beeping sounds so you can actually know wtf is going on :)
- yuhong 10y agoSuper I/O is not dead. It has the PS/2 keyboard and mouse ports for example.
