You can also disable this option. Disabling the user window causes the
PCI-MXI-2 to request the minimum amount of address space on the
PCI bus. With the window disabled, you will be unable to perform any
low-level function calls such as
VXIpeek()
,
VXIpoke()
, and
MapVXIAddress()
.
It is recommended to have a user window of at least 64 KB, and the default
setting for the user window is set at this value. If you are going to be
initiating transfers to a wide variety of addresses in both A24 and A32, you
should increase the size of the user window. Any change you make to the
size of the user window requires that you reboot your computer.
The size of the driver window, however, is system defined and is not user
configurable.
Note
Neither the user window nor the driver window can be placed below 1 MB with the
Linux NI-VXI driver. Therefore, the Place below 1 MB option and the Window Base
option will always be disabled.
Expansion ROM
Use the Enable expansion ROM option to enable or disable the
PCI expansion ROM. The expansion ROM is enabled by default. It is
recommended to retain the default setting. This option is included in
vxitedit
in case future versions of the PCI-MXI-2 do not implement a
PCI expansion ROM.
VXI/VME-MXI-2 Configuration Editor
Before running the VXI/VME-MXI-2 Configuration Editor, you must
run

.
Note
Throughout this section, the term VXI/VME-MXI-2 denotes that the information
applies equally to the VXI-MXI-2 or the VME-MXI-2.
Upon entering the VXI/VME-MXI-2 Configuration Editor, the program
displays a list of VXI/VME-MXI-2 boards that
resman

Select the device you want to configure from the Detected Boards
pull-down list, or you can select User LA and type in the board’s logical
