Fixes & Enhancements
- Fixed an issue where the system stops responding when you turn it on. This issue occurs after you perform the RTC Reset and enable the Intel Trusted Execution Technology (TXT) and Secure Boot options in the BIOS Setup.
Important Information
- Once the BIOS is upgraded to version 1.32.1 or later, you cannot downgrade the BIOS to versions earlier than 1.32.1. BIOS downgrades are restricted when there are security updates and important fixes with earlier versions that impact the functionality of the system.
- If you want to upgrade BIOS from version 1.13.0 or previous to version 1.17.2 or later, ensure to upgrade version 1.15.2 first, and then you can upgrade to a newer BIOS version.
- BIOS updates take no more than 5 minutes to be installed on your system. You can install the updates in the background while using the system.
