4.9. EEPROM saved CMOS Setup

The EEPROM has different functions, as listed below:

 Backup of the CMOS-Setup values.

 Storing system information (i.e., version, production date, customization of the board, CPU type).

 Storing user/application values.

The EEPROM will be updated automatically after exiting the BIOS setup menu. The system will operate also

without any CMOS battery. While booting, the CMOS is automatically updated with the EEPROM values.

Press the Esc-key while powering on the system before the video shows the BIOS message and the CMOS

will not

be updated.

This would be helpful, if wrong parameters are stored in the EEPROM and the setup of the BIOS does not

start.

If the system hangs or a problem appears, the following steps must be performed:

1. Reset the CMOS-Setup (disconnect the battery for at least 10 minutes).

2. Press Esc until the system starts up.

3. Enter the BIOS Setup:

a. load DEFAULT values

b. enter the settings for the environment

c. exit the setup

4. Restart the system.

The user may access the EEPROM through the INT15 special functions. Refer to that chapter in the GEODE

LX800 manual on the Product CD.

The system information is read-only and uses the SFI functions. Refer to the GEODE LX800 manual.
