Dell XPS 15 (9550) – UEFI BIOS – BIOS Defaults vs. Factory Settings

Hello,

When I press Restore Settings button in BIOS setting (through F2 when Dell logo is displayed at booting) then the dialog with two options is shown:

  • BIOS Defaults
  • Factory Settings

What is the difference about these two options (BIOS Defaults vs. Factory Settings) please?

Thank you.

RE: Dell XPS 15 (9550) – UEFI BIOS – BIOS Defaults vs. Factory Settings

JAROSLAVHORAK,

Restore Default Manufacturing Settings

Use this option to reset all BIOS configuration settings to their default manufacturing values and delete all UEFI non-volatile variables, such as boot configuration and Secure Boot security keys (if Secure Boot is enabled). Previous changes that you have made might be lost.

The difference between this action and the Restore Default System Settings option is that Restore Default Manufacturing Settings erases all UEFI variables. An OS can write UEFI variables that store such things as entries in the boot order and key database information for Secure Boot. When you Restore Default Manufacturing Settings, this information is cleared, whereas it is retained when you Restore Default System Settings.

You can save a custom default configuration to use during a system restore. Doing so saves settings you might otherwise lose
