Is MXI-3 Supported In Windows Vista or Windows 7?Hardware: VXI/VME/MXI>>MXI Interfaces>>PXI-8330, PXI/CompactPCI>>Controllers>>PXI-8335
Problem: I have upgraded my system to run a newer version of Windows and would like to use the same PXI remote controller. Can I use MXI-3 with Windows Vista or Windows 7? Solution: MXI-3 is not supported under Windows Vista or Windows 7 and will not work. Devices connected by MXI-3 will not be detected by Windows or show up in MAX. This is because MXI-3 uses a WASP ASIC which has an NI developed PCI-to-PCI bridge. Newer versions of Windows do not load the Standard PCI-to-PCI Bridge Driver for MXI-3 due to several issues with the WASP ASIC. One of the problems is the lack of an ISA EN bit in the WASP ASIC. The ISA EN bit causes a bridge to forward I/O space transactions in the last 768 bytes of each 1K block (a legacy issue caused by too few address lines in ISA). The WASP ASIC ties this bit to 0, which interferes with Window's assumptions about how the bit should behave on a specification compliant PCI-to-PCI bridge and results a device error in Windows Device Manager. If you must upgrade your system, you should either upgrade to MXI-4 or MXI-Epress for remote control or use an Embedded Controller which support later versions of Windows.
