whether the VXIpc-700 boots off the factory-configured half or
the user-modified settings. This is useful in the event that the
user-configured half of the EEPROM becomes corrupted in such a way
that the VXIpc-700 boots to an unusable state. In its default setting, the
VXIpc-700 boots off the user-configurable half.
Figure 4-5 shows the configuration settings for EEPROM operation.

is the software configuration utility in the NI-VXI software.
This utility is described in the NI-VXI Software Manual for the
VXIpc 800/700 Series, which you can access through the
c:\images\manuals
directory. You can use this utility to edit the
configuration of the VXIpc-700. Some of these settings are stored in
files that are read by the NI-VXI software, while other settings are
stored directly in the VXIpc-700 EEPROM. Certain EEPROM
configurations can lock up your PCI computer while it is booting up.
Generally, only the size and location of the memory windows can cause
your VXIpc-700 to lock up your system. For example, many PCI-based
computers will not boot if a board in its system requests more memory
space than the computer can allocate. If you encounter this situation you
should reduce the size of the VXIpc-700 user window.
If this situation occurs after you change the configuration, perform the
following steps to reconfigure the VXIpc-700.
1.
Turn your computer off.
Warning: To protect both yourself and the mainframe from electrical hazards, the
mainframe should remain off until you are finished changing the settings
on the VXIpc-700 module.
2.
Change jumper W7 as shown in Figure 4-5b to restore the factory
configuration.
