3.6.1 Configure the BIOS for Performance Tuning
It is recommended that non-essential interfaces (such as, onboard audio, USB, LAN,
external SATA, etc.) be disabled when performance tuning to simplify the process.
Once the performance parameters have been optimized, the onboard features can be
re-enabled.
Scroll to “Configuration” > “On-Board Devices” and use the submenus to disable these
features (refer to Figure 3.3).

NOTE
Do not disable the USB port where the keyboard is
connected.
