I'd bet it's covered there either in BIOS settings and/or jumpering the slot

I think I need to do pin shorting but can someone confirm ? I cannot see this mobo in the list.

That isn't an all inclusive list.  Try the A1 B17 jumper and see if it detects. It's a quick troubleshooting step to find out if that is your issue.
