APPENDIX B: DUAL BIOS INTRODUCTION

Failure when booting up BIOS is not uncommon and can occur most often during a power failure, a
mishandled BIOS update, a malware attack resulting in data corruption. When it happens, recovering
procedures consume considerable time and effort. Lanner understands this pain and have empowered our
products with the Dual BIOS feature.
How Dual BIOS Works
Dual BIOS features two physical BIOS ROMs soldered onto the motherboard, carrying two separate BIOS
images. If the Primary BIOS (default) is not functioning correctly and fails to respond within seconds (~25
seconds to 2 minutes, depend upon appliance), the system will invoke a bootup from the Secondary BIOS,
automatically restarting the system and launch the operating system.
2nd Gen Dual BIOS
To provide increased flexibility and usage protection, Lanner has released the 2nd Gen Dual BIOS function on
Lanner appliances. With 2nd Gen Dual BIOS, both the primary BIOS and secondary BIOS can be updated and
flashed using the BIOS Tool to run different versions of BIOS ROMS independently for maximum compatibility.
This additionally allow users to switch BIOS ROMS for booting up, toggling between primary BIOS and
secondary BIOS.
● Flexible recovery timer control
Users can designate the amount of time before recovery BIOS launch. The amount of time is no longer fixed
to 7 minutes.
● Flexible Dual BIOS ROMs control.
Users can flash both the Primary BIOS and Secondary BIOS, thus run different versions of BIOS ROMS
independently for maximum compatibility.
