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
measure and should not be needed under normal circumstances. When this
switch is off (its default setting) the factory configuration of the EEPROM
is protected so any writes to the factory area will be ignored. The factory
area is protected regardless of the setting of switch 1 of U21.
Figure 4-5 shows the configuration settings for EEPROM operation.
The settings of switches 3 and 4 have no effect on EEPROM configuration.
a. Boot from User Configuration (Factory Configuration Protected) (Default)
b. Boot from Factory Configuration (Factory Configuration Protected)
c. Boot from User Configuration (Factory Configuration Unprotected)
d. Boot from Factory Configuration (Factory Configuration Unprotected)
