MXIbus Termination

Configuration EEPROM

The VME-MXI-2 has an onboard EEPROM, which stores default register
values that are loaded at power-on. The EEPROM is divided into two
halves—a factory-configuration half and a user-configuration half—so you
can modify the user-configurable half while the factory-configured half
stores a backup of the default user settings.

Use switches 1 and 2 of the four-position switch at location U21 to control
the operation of the EEPROM. The Restore Factory Configuration switch
(switch 1) causes the VME-MXI-2 to boot from the factory-configured half
instead of the user-modified settings. This is useful in the event that the
user-configured half of the EEPROM becomes corrupted in such a way that
the VME-MXI-2 boots to an unusable state.

The Change Factory Configuration switch (switch 2 of U21) lets you
change the factory-default configuration settings by permitting writes to the
factory settings section of the EEPROM. This switch serves as a safety
