Managing Devices

RTX64 allows RTSS processes to directly access PCI/PCIe devices. For a RTSS process to utilize a device that device must be controlled by the RTX64 plug-and-play driver. It cannot be used by Windows. This means that all of the device’s resources are acquired by RTX64 and are exclusively used by RTX64 processes. Converting a Windows device to an RTX64 device can be done using the Windows Device Manager to update a device’s driver software.

NOTE: Certain Network Interface Cards (NICs) will be automatically converted to RTX64 control when the first NIC is converted to RTX64. This occurs because the Hardware ID of the NIC in the Windows driver's INF file is not more specific than the Hardware ID of the NIC in the RTX64 driver's INF file. This causes Windows to treat both drivers as equally capable of controlling the NIC. In this case, Windows chooses the newly installed driver over an older driver. Because the RTX64 driver is the newer one, Windows automatically assigns ownership of the NIC to RTX64. If the NIC needs to be used under Windows, convert it back to the original driver using the Windows Device Manager.

NOTE: RTX64 does not support ISA devices Industry Standard Architecture (ISA) is a computer bus standard for IBM PC compatible computers. .
