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.
Warning: 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 to the ON position as shown in
Figure C-2 to restore the factory configuration.
