Owners Manual

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.
