11.3 BIOS update
Writing down the BIOS Setup settings
Before you update your BIOS Setup settings, you should write down the values so that you
can restore them after the BIOS update, if necessary.
Updating the BIOS default values
It is imperative that you update the BIOS default values after a BIOS update:
34. Keep the F2 key pressed during the device start until the setup menu is displayed on the
screen.
35. Open the defaults using the F9 key.
36. Adjust the BIOS setup settings once again, if necessary.
Reboots
Several reboots can be carried out after a BIOS update. These reboots are initiated by the
Management Engine (ME). The reboots are required by the ME to adapt itself to the changes
in the BIOS update.
