Hi,
My friend has bought this board for his CNC machine, he wanted me to set it up this new hardware for him, first of all I can not find any datasheet or model for this board, do you happen to know it? also I can not figure out how this board is working... it seems it's a two layer board and if you see the pictures in detail you could see that it has left almost all the pins except the Power pins and two signal pins unconnected!!!
they are PCI_PRSNT1 and PCI_PRSNT2 signals and they are also disconnected!
