Bios; Battery Jumper; Configuring The Xpressrom Bios - Lippert Cool SpaceRunner LX800 Technical Manual

4.3 BIOS

The Cool SpaceRunner-LX800 is delivered with an Insyde Technology XpressROM BIOS. The default settings
guarantee a "ready to run" system, even without a BIOS setup backup battery.
All setup changes of the BIOS are stored in the CMOS RAM. A copy of the CMOS RAM, excluding date and time,
is stored in the flash memory. This means that even if the backup battery runs out of power, the BIOS settings are
not lost. Only date and time will be reset to their default value.
The soldered battery will keep that information over 2 years without any activation of the board.
That depends on the use of the board. When power is up, the battery does not lose capacity.

Because of the flash storage in the BIOS the settings will keep their information after.
Except the Real Time Clock will not
If the board should be stored for longer times, this is the best solution to save the capacity.
The battery loses 1% of its capacity over self-discharge per year without the jumper.
The BIOS revision can be easily updated on-board with software under DOS.
