RTX provides a mechanism for converting existing Windows PCI and ISA devices to RTX devices that RTSS applications can control. Converting a Windows PCI or ISA device to an RTX device requires two distinct steps:

You must complete both these steps, described in Converting a Windows Device to an RTX Device, to ensure a successful conversion.  

An INF file is a text file that contains all the information necessary to install a device, such as driver names and locations, registry information, and version information. The RtxPnp.inf file stores all the information for the RTX PnP Driver (RtxPnp.sys). Adding RTX INF support appends the Rtx Pnp Driver INF file with additional information about Windows devices to the RTXPnp.inf file. Once supported is added, the Windows Device Wizard lists an RTX PnP supported driver for the device.

To add RTX INF support for a device:

NOTE:  Each PCI device is identified by a bus number, a device number and a function number (bus/device/function). Each device (card or peripheral) can perform a single function, or up to a maximum of eight functions. In cases where a PCI card has multiple ports, and each port provides a different function, access to each port can be distinguished by a unique bus/device/function combination. In cases where a PCI card has multiple ports, but only provides a single function, RTX only provides access to the first port.
