Enabling or disabling the One-Time Boot Menu F11 prompt
Use this option to control whether you can press the F11 key to boot directly to the One-Time Boot Menu during the current boot. This option does not modify the normal boot order settings. When this option is enabled, you can boot directly into the One-Time Boot Menu in the System Utilities by pressing F11 in the POST screen after a server reboot.
Procedure
From the
System Utilities screen, select
System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > One-Time Boot Menu (F11 Prompt).
