APPENDIX C: DUAL BIOS INTRODUCTION
Why Dual BIOS?
Failure of booting up BIOS is not uncommon to most experienced users, yet it can be the worst nightmare.
This occurs mostly during a power failure or a mishandled BIOS update, after a malware’s attack that
corrupted the data on the chip, or, at worst, due to physical damage that caused the BIOS not to function.
When it happens, not merely will the recovering procedures consume considerable time and effort, but all
you work might also be to no avail. Eventually, you are left with no choice but to ship the board back to the
manufacturer.
Lanner understands this pain and has empowered our products with the Dual BIOS feature. Normally, the
Primary BIOS is used to boot the OS during powering up; when Primary BIOS is down, the Recovery BIOS
automatically jumps in to boot up the OS for the User to take further steps such as performing data backup
and BIOS upgrade.
