  • Once the update process has started, do not power down your system until the update is complete. The update process will take up to 3 minutes. If a BIOS update process is interrupted, your computer may not function properly. We recommend the process be done in an environment with a steady power supply (preferably with UPS).
  • Downgrading the BIOS to an earlier version isn’t recommended and might not be supported. An earlier BIOS version might not offer support for the latest processors, bug fixes, critical security updates, or support the latest board revisions currently being manufactured. If you're trying to downgrade to a previous BIOS version and its Intel® ME Firmware version is older than that currently on the motherboard, then the downgrade is NOT supported.
  • Before you start, record all BIOS settings that have been changed from default, so they can be restored after completing the BIOS update.

BIOS Recovery by Security Jumper

Note:

  • BIOS recovery using the BIOS security jumper will clear Trusted Platform Module (TPM) keys, Intel® Platform Trust Technology (Intel® PTT) keys, and High-bandwidth Digital Content Protection (HDCP) keys.  
  • These keys will not be restored after the BIOS recovery.
  1. Download and save the Recovery BIOS file to a USB device. Example:

  1. Double-click the *.RECOVERY.zip to extract its files.

Note

  1. It is important to extract the files with the file folder structure as shown.
