Getting started

This document describes the procedure of updating BIOS on an SN3100 model firewall from version R1.06 to version R2.30.

INFORMATION
BIOS has to be in version R2.30 in order to integrate all fixes that address stability issues encountered by the chipset and the Intel® CPU on the SN3100 model firewall.

Once you have updated the BIOS, the following features 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 disabled by default on SN3100 firewall models. If it had been enabled on your firewall, 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. You will need to seal it again.

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