132 PROM System
Configuration
EEPROM Factory Reset
Performing a factory reset erases all settings and tables. All
configuration changes ever made to the router will be deleted. The
router will be set to the factory defaults it was shipped with and will no
longer have an IP address.
Please make sure you wish to wipe out all settings and configure the
router from scratch before you perform a factory reset.
Execute Bootload
Choosing this option accepts the changes made in the PROM program
and begins the router’s startup sequence.
Executing a bootload can also begin the Software Update procedure, if
enabled.
