Getting started

This document describes the procedure of updating BIOS on an SNS SN-L-Series (SN-L-Series-2200 and SN-L-Series-3200) model firewall from version R1.02 to version R1.05.

INFORMATION
BIOS version R1.05 is essential for fixing instability issues that the Intel® processors on these firewalls encounter.

Once you have updated the BIOS:

• 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.

   

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