I have a legacy application that will only allow you to choose one of three standard I/O (0x378 being one) to communicate with its corresponding device. I have a PC with no parallel port that we added a port to. The port's I/O address is in the 900 range and can be change a little, but not to any of the one the application wants. There is no option in the BIOS to set the PCI slot addess.
Is there any way, either through a virtual machine, or a command line, etc. to redirect the data coming to and from the progam to the add-on card?
