1. Choosing the Right Computer for MXI-Express Controllers

MXI-Express is successfully used on a variety of name brand PCs, laptops, and motherboards containing a PCI Express or ExpressCard slot. However, more complex MXI-Express configurations may pose a challenge for the BIOS of the systems to correctly enumerate all of the resources necessary, which may cause the system to freeze during the boot process. This symptom, known as a BIOS incompatibility, occurs in only specific situations. To benefit from the latest BIOS improvements and reduce the chances for incompatibility, always make sure that the BIOS on the system is the latest version from the vendor.

If you encounter problems with your MXI-Express system, refer to the MXI Compatibility and Connectivity Troubleshooting Guide.

2. Other Controller Options

If you cannot find a computer that does not have BIOS incompatibilities, an alternative option is to use a PXI embedded controller. PXI embedded controllers from National Instruments have a BIOS that is written to handle the most complex chassis expansion configurations allowed by the PCI and PCI Express specification. In contrast to MXI-Express, these controllers are compact enough to fit inside the chassis.

3. Installing MXI-Express Driver Software

Prior to installing your MXI-Express kit, you will need to install the appropriate software to gain full functionality of MXI-Express. Typically, any NI driver that is required for PXI peripheral products such as NI-DAQmx or NI-VISA will install everything that is needed for MXI-Express support. These drivers are included on the NI Driver CD, which is shipped with all PXI products from National Instruments. You can also find these on ni.com/support.

Note for Advanced MXI-Express Users

If you do not wish to install these NI drivers and need only the minimum software necessary to gain full MXI-Express support and NI chassis identification and configuration, then only PXI Platform Services is required. You can install this software either manually from any PXI peripheral driver from National Instruments or by visiting ni.com/support and select the Drivers and Updates option. Then search for “PXI Platform Services” in the Search Within Results search bar.

For more information on how to install an MXI-Express product, refer to the shipping documentation that is included with the product.
