access onboard DRAM. Accessing this region will cause your VME-MXI-2 to behave
incorrectly.

If you install more than one VME-MXI-2 in a single VMEbus chassis,
you must select a user-defined pin for use by the VME-MXI-2. The
VME-MXI-2 modules use this signal to disable the bus timeout unit(s) on
the other VME-MXI-2 modules during VMEbus accesses that map to the
MXIbus. This is done because the MXIbus bus timeout unit should be the
