You can find more release information on ni.com.
MXI-Express BIOS Compatibility 21.8 supports the following operating systems:
Note Refer to Unsupported Windows Operating Systems for more information about support for Microsoft Windows OSes.
|Note||Install this software only on a system that cannot boot with a MXI-Express connection or recognize PXI or PXI Express devices behind this connection.|
Follow these steps to install the software:
|Note||You cannot configure your MXI-Express device in Safe Mode. Refer to Troubleshooting for more information.|
|Note||For the PXIe-8388 and PXIe-8389, the bank of DIP switches is on the PXI Express remote controller, not the PCI Express MXI-Express board.|
|Note||The number of DIP switches on hardware may vary.|
You can use the above procedures to place the device back in Mode 0 (the default) for use without NI MXI-Express BIOS Compatibility Software. To do this, follow the above steps, but set DIP switch 1 back to the Off position, or for the ExpressCard-8360 or NI PCIe-8398 click the Disable button in the NI MXI Configuration program.
|Note||All MXI-Express devices, including the ExpressCard-8360, retain their mode settings even after removing the board from the slot or plugging it into a different computer.|

Note: Some compatibility information may only be available in the archive attached to the NI Hardware and Operating System Compatibility page. For historic driver and OS support information, refer to the readme for the relevant driver version.
NI MXI-Express BIOS Compatibility Software 21.8 requires one of the following boards with the specified part numbers listed on the MXI-Express Products and MXI-Express BIOS Compatibility Software Compatibility page:
The above hardware is available in several MXI and MXI-Express kits. Contact a customer sales representative for more information.
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.
For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.
For more information about NI support for Windows 10, refer to NI Product Compatibility for Microsoft Windows 10.
MXI-Express BIOS Compatibility no longer supports Windows Vista/XP/7/8.x, Windows Server 2003/2008/2012, or any 32-bit Windows operating system. Versions of this product that ship after May 1, 2021, may not install or execute correctly on these operating systems. For detailed information about NI operating system support, visit https://www.ni.com/r/win32bitsupport.
Use this software only if you are experiencing problems connecting your PXI or PXI Express chassis to your computer using MXI-Express. NI MXI-Express BIOS Compatibility Software works around common BIOS limitations using functionality available on MXI-Express hardware.
Install NI MXI-Express BIOS Compatibility Software if your computer does not boot when connected to your PXI chassis through MXI-Express, or if Windows does not properly discover your devices. (For example, there is a yellow exclamation point on a PCI to PCI bridge in Windows Device Manager, despite drivers for all devices being installed.) These situations often are due to programming errors in PCI Express device configuration of the BIOS. To use this software, you need a MXI-Express device that supports Mode 1 operation. Refer to Supported Hardware for more information.
Do not install NI MXI-Express BIOS Compatibility Software if your computer connects without error to your PXI or PXI Express chassis using MXI-Express. In this case, installing the software needlessly increases the system complexity and may cause errors.
NI MXI-Express BIOS Compatibility Software detaches from a running system when booting Windows into Safe Mode. This allows a system to boot without the software affecting it, and thus allows you to uninstall the software if you run into problems.
If you have correctly configured your MXI-Express hardware for Mode 1 operation (refer to Installation Instructions) and still experience difficulties, you can either:
|I am seeing a code 12 or code 31 error in Device Manager on one of the devices in my chassis, or a PCI-PCI bridge or PCI Express Root Port.||The Windows Event Log may contain more information about the error. The Event Log is in the Windows Control Panel under Administrative Tools. Look for events in the System log with nipximxk or nipxirfk listed as the source. Whether or not any relevant events exist in the log, contact National Instruments and report the issue.|
|I uninstalled the software, but now I cannot access my PXI devices. They are not present in Device Manager or MAX.||Ensure that your MXI-Express device is in Mode 0. Refer to the Installation Instructions for mode setting instructions. If you are using an ExpressCard-8360, you must install NI MXI-Express BIOS Compatibility Software to access the mode setting.|
|I moved my MXI-Express device to another computer that does not have NI MXI-Express BIOS Compatibility Software installed. My devices in the chassis are not present in Device Manager or MAX.||Ensure that your MXI-Express device is in Mode 0 for use without NI MXI-Express BIOS Compatibility Software. The configured mode is set on the device itself and follows the device when plugged into different systems. This is true for all MXI-Express devices, including those configured through software.|
|I cannot configure the mode of operation for my ExpressCard-8360 or NI PXIe-8398. The configuration software does not find the device.||Ensure that your computer is booted into Normal Mode (not Safe Mode). MXI-Express devices are not detected in Safe Mode. If you have trouble booting into Normal Mode, be sure you have followed the instructions for changing modes in the Installation Instructions. Hot-plugging the ExpressCard-8360 solves most boot-time problems. Hot-plugging a NI PXIe-8398 is not supported.|
|The installer displayed a pop-up warning message about the detection of a limited bus number range.||No troubleshooting steps are necessary yet. The purpose of the warning is to notify you of a BIOS setting that is limiting the amount of hardware you can attach to your computer. You may not run into this limit; however, if you do, code 12 or code 31 errors are likely to be present in Device Manager, as well as an error message in the Windows Event Log. Look for events in the System log with nipxirfk listed as the source.|
|I see a message in the Windows Event Log notifying me that the maximum bus number limit was reached.||Not all of your PXI chassis could fit within the limitations of your motherboard, and therefore some of your devices may be missing or not working. When placing devices in your PXI system, filling the first connected chassis first ensures they are allocated resources first. Also, consolidating devices toward the left side of any non-full chassis in your system could help. If you still encounter issues with getting your devices to work, try removing some devices or a chassis. Contact National Instruments for more support on this issue.|
|The installer displayed a pop-up warning message about the detection of multiple PCI root buses.||No troubleshooting steps are necessary yet. The purpose of the warning is to notify you of your computer's hardware configuration which divides PCI bus resources into independent segments. It is possible that the amount of hardware you can attach to your computer is limited by the size of these segments. You may not run into a limitation; however, if you do, code 12 or code 31 errors are likely to be present in Device Manager, as well as an error message in the Windows Event Log. Look for events in the System log with nipxirfk listed as the source. If you experience this problem, try inserting your MXI-Express device into a different PCI-Express slot attached to one of the other root buses.|
|I see a message in the Windows Event Log notifying me that the software has found a configuration that is currently not supported.||Verify that the MXI-Express cable is attached to both your host PC and the PXI or PXI Express chassis, and that the PXI or PXI Express chassis is powered on at the time the host PC is powered on. It is possible to see this message if MXI-Express hardware is not detected.|
