To install the DDR3L modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR3L module so that the key of the DDR3L module
aligned with that on the memory slot.
2. Gently push the DDR3L module in an upright position until the clips
of the slot close to hold the DDR3L module in place when the
DDR3L module touches the bottom of the slot.
3. To remove the DDR3L module, press the clips with both hands.
** Channel-A slot must be installed with

BIOS SETUP
Warning:
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both AMI and your system manufacturer
to provide the absolute maximum performance and
reliability. Changing the defaults could cause the system to
become unstable and crash in some cases.
BIOS Introduction
The BIOS (Basic Input/Output System) installed in your computer
system’s ROM supports Intel processors. The BIOS provides critical
low-level support for a standard device such as disk drives, serial ports
and parallel ports. It also password protection as well as special support
for detailed fine-tuning of the chipset controlling the entire system.
BIOS Setup
The BIOS provides a Setup utility program for specifying the system
configurations and settings. The BIOS ROM of the system stores the
Setup utility. When you turn on the computer, the BIOS is immediately
activated. Pressing the <Del> key immediately allows you to enter the
Setup utility. If you are a little bit late pressing the <Del> key, POST
(Power On Self Test) will continue with its test routines, thus preventing
you from invoking the Setup. If you still wish to enter Setup, restart the
system by pressing the ”Reset” button or simultaneously pressing the
<Ctrl>, <Alt> and <Delete> keys. You can also restart by turning the
system Off and back On again. The following message will appear on the
screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to select,
the <PgUp> and <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

Enables Legacy USB support. AUTO option disables legacy support if
no USB devices are connected. DISABLE option will keep USB devices
available only for EFI applications.
XHCI Hand-off
This is a workaround for OSes without XHCI hand-off support. The
XHCI ownership change should be claimed by XHCI driver.
EHCI Hand-off
This is a workaround for OSes without EHCI hand-off support. The
EHCI ownership change should be claimed by EHCI driver.
USB Mass Storage Driver Support
Enable/Disable USB Mass Storage Driver Support.
USB Transfer time-out
The time-out value for Control, Bulk, and Interrupt transfers.
Device reset time-out
USB mass storage device start Unit command time-out.
Device power-up delay
Maximum time the device will take before it properly reports itself to the
Host Controller. ‘Auto’ uses default value: for a Root port it is 100ms, for
a Hub port the delay is taken from Hub descriptor.

D. Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sorts of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user will
restart the WDT at regular intervals before the timer counts to zero.
