How to Fix an Invalid EEPROM Configuration
The NI-VXI software includes a configuration utility you can use to edit
the configuration of the VXI/VMEpc 600 Series. Use T&M Explorer under
Windows 95/NT. Some of these settings are stored in files that are read
by the NI-VXI software, while other settings are stored directly in the
VXI/VMEpc 600 Series EEPROM. Certain EEPROM configurations can
lock up your computer while it is booting up. Generally, only the size and
location of the memory windows can cause your VXI/VMEpc 600 Series
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 VXI/VMEpc 600 Series user window.
If this situation occurs after you change the configuration, perform the
following steps to reconfigure the VXI/VMEpc 600 Series:
1.
Turn off your computer.
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 VXI/VMEpc 600 Series.
2.
Change jumper W9 to the position shown in Figure 3-11b 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
VXI/VMEpc 600 Series.
4.
Run your software configuration utility to re-adjust the
VXI/VMEpc 600 Series configuration.
