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.
To protect both yourself and the computer from electrical hazards, the computer
