Appendix B EEPROM Configuration
Fixing an Invalid EEPROM Configuration
Caution To protect both yourself and the chassis from electrical hazards, leave the
computer or chassis off while you change the settings on the PCI-MXI-2, PCI-MXI-2
Universal, or PXI-8320 module.

Certain EEPROM configurations can cause your PCI-based or
PXI/CompactPCI computer to lock up while in its boot process. Generally,
only the size and location of the memory windows can cause the
PCI-MXI-2, PCI-MXI-2 Universal, or PXI-8320 to lock up your system.
For example, many PCI-based or PXI/CompactPCI computers will not
boot if a board in the system requests more memory space than the
computer can allocate. If you encounter this situation, you should reduce
the size of the PCI-MXI-2, PCI-MXI-2 Universal, or PXI-8320 user
window.
If this situation occurs after changing the configuration, complete the
following steps to reconfigure the PCI-MXI-2, PCI-MXI-2 Universal,
or PXI-8320.
1. Power off your computer or chassis.
2. Remove the PCI-MXI-2, PCI-MXI-2 Universal, or PXI-8320 from
your PCI-based computer or PXI/CompactPCI chassis.
3. Change switch 1 (FOV) on U17 or U6 to the ON position as shown in
Figures B-3 or B-4 to restore the factory configuration.
