In the UEFI settings you can modify very fundamental system properties, e.g. disable booting from USB. Access to these settings should be protected by a password.

Instructions for IGEL UD LX devices

 If UEFI is not enabled, see the instructions under UEFI Secure Boot Enabling Guides.

By default no UEFI password is set on IGEL UD devices. To set a password, do the following:

  1. Hold down the [Del] key ([F2] key for UD2) while booting.
    The UEFI menu opens.
  2. Using the arrow and return keys, go to SCU.
    The Setup Utility opens.
  3. Using the arrow and return keys, go to Security.
  4. Use the arrow keys to select Set Supervisor Password
  5. Hit [Return].
  6. Enter the desired UEFI password and hit [Return]
  7. Enter the same UEFI password again and hit [Return] twice.
  8. Hit [F10] in order to save and exit.
  9. Confirm Exit Saving Changes? by hitting [Return].
    The system boots, and the UEFI settings are now password-protected

Refer to the instructions of your BIOS/UEFI vendor

Alternatively, try pressing [F12] (in general), [F10] (Intel devices) or [F9] (Hewlett-Packard devices) to access the BIOS/UEFI settings. If this does not work, try pressing [Del], [F1] or [F2] during booting.
