The presence of menus and BIOS settings are dependent on your board model, hardware components
installed, and the BIOS version. BIOS menu titles may differ.
If any problems occur after making BIOS settings changes (poor performance, intermittent issues, etc.), reset
the desktop board to default values:
1. During boot, enter the BIOS setup by pressing F2.
2. Press F9 to set defaults.
3. Press F10 to Save and Exit.
If the system locks or won’t boot after making BIOS settings changes, perform a BIOS recovery as described
