Specify the following categories of USB devices to enable:
●
Allow all USB devices (default)
●
Allow only keyboard and mouse
●
Allow all but storage devices and hubs.
When some devices are restricted, the system will disable USB ports that do not meet the allowed
criteria. This feature is usually combined with similar policies within the operating system since USB
devices can be moved to
different
ports. The ports disabled by the BIOS will remain disabled until the
system is restarted.
Option ROM Launch

Power Management
Options
Runtime Power Management
(enable/disable)
Allows certain operating systems to reduce processor voltage and frequency when the current software
load does not require the full capabilities of the processor. Default is enabled.
Extended Idle Power States
(enable/disable)
Allows certain operating systems to decrease the processors power consumption when the processor is
idle. Default is enabled.
S5 Maximum Power Savings
(enable/disable)
Enabling this feature reduces the power of the system as much as possible in the S5 state. Power is
removed from the wake up circuitry, the expansion slots, and any management features while in S5.
Default is disabled.
SATA Power Management
(enable/disable)
Enables or disables SATA bus and/or device power management. Default is enabled.
PCI Express Power Management
(enable/disable)
Enabling this option permits the PCI Express links to use Active Power State Management (ASPM) to enter
lower power states while not in use. Default is enabled.
Power On from Keyboard Ports
(enable/disable)
When enabled, this feature allows a key press to power on the system when it is
off
(S5 state). If using a
USB keyboard, it must be plugged into one of the rear ports labeled with the keyboard icon. Default is
disabled.
Unique Sleep State Blink Rates
(enable/disable)
This feature is designed to provide a visual indication of what sleep state the system is in. Each sleep
state has a unique blink pattern. Default is disabled.
NOTE:
A normal shutdown goes to the S4 state.
S0 (On) = Solid white LED.
S3 (Stand By)= 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (white LED) — repeated
cycles of 3 blinks and a pause.
S4 (Hibernation)= 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (white LED) —
repeated cycles of 4 blinks and a pause.
