If the system switched to Secondary BIOS to boot up, it can be asserted that the Primary BIOS is having a
severe problem that it failed to function. Before users determine that the BIOS chip is completely corrupted
and unusable, it would be advisable to try to update the Primary BIOS.
Flashing a BIOS needs to be carefully completed, especially pertaining to a corrupted BIOS, which can lead
to an unusable system if done incorrectly.
To get ready for a BIOS update, acquire the following BIOS
resources from Lanner technical support:
⚫
Firmware and Flash Tool
⚫
BIOS Engineering Spec
Before you start, make sure you select the correct firmware version, correct BIOS (Primary or Secondary) and
go through the
instructions for BIOS update in BIOS Engineering Spec thoroughly. If you cannot be certain
if this version is correct for your system, please contact Lanner Technical Support.
Note:
1. When the system enters the BIOS menu, BIOS will disable the watchdog function. In another words, even
over the set time limit in the BIOS menu, the system will not reboot automatically.
2. Dual BIOS feature cannot work with the BIOS BOOT Guard function.
3. To update and reflash BIOS, it is mandatory that both BIOS will need to be updated. This action is to
avoid ME code variations on both of the BIOS, which can lead to unexpected risks and errors.
Disclaimer
Under no circumstances will Lanner accept responsibility or liability for damages of any kind whatsoever resulting or
arising directly or indirectly from a BIOS update.
Warning
DO NOT power off or reset the system during BIOS updating process.
