Questions and answers
Use this section to answer your questions about nonvolatile memory.
1. How can the BIOS settings be restored (returned to factory settings)?
IMPORTANT: The restore defaults feature does not securely erase any information on your hard

The restore defaults feature does not reset the Custom Secure Boot keys. See question and

2. What is a UEFI BIOS, and how is it different from a legacy BIOS?
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface
between the platform firmware and an operating system (OS). It replaces the older BIOS
architecture but supports much of the legacy BIOS functionality.
