Flash Backup Feature

The microETXexpress®-SP supports a new functionality called ―Flash Backup‖. This new feature allows saving custom
defaults directly into the Flash. With invalid EEPROM data or without a CMOS EEPROM, the module will start up with
these custom defaults. It's possible to save this BIOS with changed defaults to an image and flash it on other
modules.
