4.11 Load Fail-Safe Defaults
If this option is chosen, the last working setup is loaded from flash. Working means that the setup setting
has already led to a successful boot process.
At the first setting of the BIOS setup, safe values are loaded which lets the board boot. This status is
reached again, if the board is reprogrammed with the corresponding flash-program and the required
parameters.
4.12 Load Optimized Defaults
This option applies like described under “Remarks for Setup Use” (5.1).
At first start of the BIOS, optimized values are loaded from the setup, which are supposed to make the
board boot. This status is achieved again, if the board is reprogrammed using the flash program with the
required parameters.
4.13 Set Password
Here you can enter a password to protect the BIOS settings against unauthorized changes. Use this option
with care! Forgotten or lost passwords are a frequent problem.
4.14 Save & Exit Setup
Settings are saved and the board is restarted.
4.15 Exit Without Saving
This option leaves the setup without saving any changes.
