This might sound a bit daft but how do I enable POST signalling when the case has no microphone connector? The case is a Coolermaster Cosmos 1000. It has 4 header connectors - Power, Reset, Power LED & HDD LED. (And audio connectors for HD Audio & AC97). I have a sound card and have disabled the on-board audio. Everything works fine but there are no POST beeps. Have these been done away with, like floppy drives?
