I have installed the PCI-Express card SD-PEX10005 and got the required drivers and it shows up in the system device manager. I know it is a 1 port parallel card but since it is not part of the mother board it will not show up in the bios. I am running or trying to run MACH3 CNC software and the software needs to know that the parallel port is LPT1 address 0378 hex. With my parallel cable connected to the break out box and the unit is turned on, I get no response and no reset signal. How can I make sure the parallel PCI card is set for lpt1 address 0378 hex? The device manager doesn't show what hex address it is using.Or if it does there is no way to set it at 0378 hex. Am running Windows Home Premium Service pack 1

I am answering my own question. I finaly wised up and went to the web site of MACH3 and found that their software will not work on 64 bit computers, only on 32 bit. So now I will have to go back on my old standby desktop computer. Actualy MACH3 is designed by Artsoft and allows you to run a limited program for as long as you want. To write big progarms it costs for the software but for newbee's you can't go wrong. One thing you must have  a 32 bit computer and a parallel port for LPT1.. Thankd for those that read the post, so now we all know.
