EEPROM Operation Default Settings
Fixing an Invalid EEPROM Configuration
Certain EEPROM configurations can cause your PCI computer to lock up
while in its boot process. Generally, only the size and location of the
memory windows can cause problems with the PCI-MXI-2 locking 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 PCI-MXI-2
user window.
If this situation occurs after changing the configuration on the PCI-MXI-2,
follow these steps to reconfigure the PCI-MXI-2.
1.
Turn your computer off.
Caution
To protect both yourself and the computer from electrical hazards, the computer
should remain off while changing the settings on the PCI-MXI-2 module.
2.
Remove the top cover or access port to the PCI bus.
3.
Change switch 1 (FOV) on U17 (SW1 on the PCI-MXI-2 Universal)
to the ON position as shown in Figure B-2 to restore the factory
configuration.

Restoring the Factory Configuration
Note
If you have to remove the PCI-MXI-2 module to access switch 1, follow the
installation instructions given in Chapter 2,
PCI-MXI-2 Configuration and Installation
,
to reinstall the PCI-MXI-2 module.
