Operating with setup password enabled

If Setup Password is set to Enabled, type the correct setup password before modifying the system setup options.

If you do not type the correct password in three attempts, the system displays the following message:

Invalid Password! Number of unsuccessful password attempts: <x> System Halted! Must

power down.

Password Invalid. Number of unsuccessful password attempts: <x> Maximum number of

password attempts exceeded.System halted.

Even after you turn off and restart the system, the error message is displayed until the correct password is typed. The following

options are exceptions:

● If System Password is not set to Enabled and is not locked through the Password Status option, you can assign a

system password. For more information, see the System Security Settings screen section.

● You cannot disable or change an existing system password.

NOTE:

You can use the password status option with the setup password option to protect the system password from

unauthorized changes.

Description

Enables you to select a backup disk from the following devices:

● None

● IDSDM

● SATA Ports in AHCI mode

● BOSS PCIe Cards (Internal M.2 Drives)

●

● Internal USB

NOTE:

RAID configurations and NVMe cards are not included, as BIOS does not

have the ability to distinguish between individual drives in those configurations.

NOTE:

This option is disabled if Redundant OS Location is set to None.

When set to Visible, the backup disk is visible to the boot list and OS. When set to

Hidden, the backup disk is disabled and is not visible to the boot list and OS. This option

is set to Visible by default.

NOTE:

BIOS disables the device in hardware, so it is not accessed by the OS.

NOTE:

This option is disabled if Redundant OS Location is set to None or if

Redundant OS State is set to Hidden.

When set to Enabled, BIOS boots to the device specified in Redundant OS Location.

When set to Disabled, BIOS preserves the current boot list settings. This option is set to

Enabled by default.
