The above diagram provides an overview of how the BIOS Setup Data is backed up on modules. OEM default values mentioned above refer to customer specific CMOS settings created using the System Utility tool.

Once the BIOS Setup Program has been entered and the settings have been changed, the user saves the settings and exits the BIOS Setup Program using the F10 key feature. After the F10 function has been evoked, the CMOS Data is stored in a dedicated non-volatile CMOS Data Backup area located in the BIOS Flash Memory chip as well as RTC. The CMOS Data is written to and read back from the CMOS Data Backup area and verified. Once verified the F10 Save and Exit function continues to perform some minor processing tasks and finally reaches an automatic reset point, which instructs the module to reboot. After the Automatic Reset has been triggered the module can be powered off and if need be removed from the baseboard without losing the new CMOS settings.
