VXIpc-850 Series User Manual
How to Fix an Invalid EEPROM Configuration
VXIEDIT
is the software configuration utility in the NI-VXI software.
This utility is described in Chapter 3, NI-VXI Configuration Utility, in
the NI-VXI Software Manual for the VXIpc-850 Series . You can use
this utility to edit the configuration of the VXIpc -850. 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 -850 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 -850 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-850 user window.
If this situation occurs after you change the VXIpc -850 configuration,
perform the following steps to reconfigure the VXIpc-850.
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 -850 module.
2.
Change switch S9 to the OFF position as shown in Figure 3-9b to
restore the factory configuration.
Installed System RAM
The 11 MB of installed RAM is factory configured per customer order.
You can change the amount of installed RAM on the VXIpc-850 by
installing DRAM SIMMs. Refer to Appendix A, Specifications, for
more information on SIMMs.
