Getting started

This document describes the procedure of updating BIOS on SN-M-Series-720 and SN-M-Series-920 model firewalls from version R1.03 and lower to version R1.04.

INFORMATION
BIOS has to be in version R1.04 in order to integrate all fixes that address stability issues encountered by the chipset and the Intel CPU on SN-M-Series-720 and SN-M-Series 920 model firewalls.

Once you have updated BIOS, If the following features were used, they will need to be configured again:

  • Password to access the UEFI control panel: if you had set it earlier on the firewall, it will be deleted during the BIOS update. You will need to set it again.

  • Secure Boot: this feature is enabled by default on SN-M-Series-720 and SN-M-Series-920 model firewalls as of BIOS version R1.03 in factory settings. You will need to disable it during the BIOS update. You can enable it once again after the update.

  • TPM: if it had been initialized on the firewall, it will no longer be sealed after the BIOS update. This is because at the end of the BIOS update, trusted hash values will have changed, preventing the decryption of protected private keys. You will need to seal it again.

These procedures are described in the section Required operations following a BIOS update in this technical note
