5.8.1.EEPROM Memory for Setup

The EEPROM is used for setup and configuration data, stored as an alternative to the CMOS-RTC. Option- ally, the EEPROM setup driver may update the CMOS RTC, if the battery is running down and the checksum error would appear and stop the system. The capacity of the EEPROM is 2 kByte.
