In order to configure an instance of the VTSIO Driver, you must know the resources used by the hardware. This is generally a series of IO Port numbers, memory addresses, or both.
A single instance of the VTSIO Driver can handle only a single contiguous range of IO Port numbers or memory addresses. For example, a piece of hardware might use IO ports 250 through 257 and memory addresses D0000 through D3FFF. For this application, two instances of the VTSIO driver would be required – one for the IO port range and one for the memory address range.
