Option
Description
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 changes 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.
