Reset UEFI Settings to Default
There are several ways to reset the UEFI firmware settings to the default values.
Important
The UEFI settings are stored in the SPI flash and no longer in the CMOS memory. Removing the buffer battery does not reset the settings.Option 1: Press F9
The UEFI settings can be reset by pressing F9 in the UEFI. You have to be in the Setup Utility Page to use this function.
To reset the settings without the display, proceed as follows:
- hold ESC on the keyboard to enter UEFI (about 1min. to be safe)
- Press the Down key at least 5 times
- Press return to open the Setup utility
- Press F9 and then press Return to load setup defaults
- Press F10 and then Return again to save the settings and restart
Option 2: Update the UEFI Firmware
When updating the UEFI firmware, the firmware defaults are loaded and all changes to the settings are lost.
Installing the same firmware resets these settings (e.g. UEFI update under Windows).
Option 3: Reset via RESET button
Our modules provide a function that allows to reset the UEFI to default values in case of emergency.
For this, the reset button must be pressed three times within one second.
If the module LED blinks red for a short time the reset to defaults was successful.
