BIOS version R1.05 is essential for fixing instability issues that the Intel® processors on these firewalls encounter.
The BIOS can be updated from a USB key or from the firewall’s web administration interface.

Once you have updated the BIOS from a USB key:
- 
                                                                    
The password to access the UEFI control panel will be deleted. You will need to set it again.
 - 
                                                                    
Secure Boot will be disabled. You will need to enable it again.

The TPM will no longer be sealed. You will need to seal it again.

Once you have updated the BIOS from the firewall's web administration interface:
-
