Got the post card and tried it out. With any of the cf card adapters with a cf card in, it simply doesn’t start. The power and lights are on, fans are running, but no codes show and no beeps, no video. If I then pull the cf card out, it instantly boots! What the heck?!? Here’s something else I don’t understand…with the cf card in but no power connected, the power lights on the cf adapter come on as if it’s powered…what is with that? The jumper is set to external power. Saw this behavior on both cf adapters I tried. It’s almost like something is shorting through the cf card but that doesn’t make any sense…right??
