EEPROM Configuration
How to Fix an Invalid EEPROM Configuration
The NI-VXI software includes a configuration utility you can use to
edit the configuration of the VXIpc-700. Use T&M Explorer with
Windows 95/NT or VXIedit with all other platforms. 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 3-5b to restore the factory
configuration.
3.
Turn on the computer. The computer should boot this time because the
factory-default configuration is being used to initialize the VXIpc-700
module.
4.
Run your software configuration utility to re-adjust the VXIpc-700
configuration.
5.
After saving the configuration, exit Windows and turn off the
computer.
