Option
Description
Keyboard NumLock
Enables you to set whether the system boots with the NumLock enabled or disabled. This option is set to
On
by default.
NOTE: This option does not apply to 84-key keyboards.
F1/F2 Prompt on
Error
Enables or disables the F1/F2 prompt on error. This option is set to
Enabled
by default. The F1/F2 prompt
also includes keyboard errors.
Load Legacy Video
Option ROM
Enables you to determine whether the system BIOS loads the legacy video (INT 10H) option ROM from the
video controller. Selecting
Enabled
in the operating system does not support UEFI video output standards.
This field is available only for UEFI boot mode. You cannot set the option to
Enabled
if
UEFI Secure Boot
mode is enabled.
In-System
Characterization
Enables or disables
In-System Characterization
. This option is set to
Disabled
by default. The two other
options are
Enabled
and
Enabled - No Reboot
.
NOTE: The default setting for In-System Characterization is subject to change in future BIOS
releases.
When enabled, In-System Characterization (ISC) executes during POST upon detecting relevant change(s)
in system configuration to optimize system power and performance. ISC takes about 20 seconds to execute,
and system reset is needed for ISC results to be applied. The
Enabled - No Reboot
option executes ISC and
continues without applying ISC results until the next time system reset occurs. The
Enabled
option executes
ISC and forces an immediate system reset so that ISC results can be applied. It takes the system longer to
be ready due to the forced system reset. When disabled, ISC does not execute.
