Installing the Memory
The IB897 board supports TWO DDR3L memory socket for a maximum
total memory of 8GB DDR3L memory type.
Installing and Removing Memory Modules
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
memory module for booting up**

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.

Notes on Boot Option and Windows 8 Setup
1. Before installing Windows 8, check the BIOS Setup’s Boot Option
Priorities if Boot Option #1 is set to UEFI mode (which would be the
DVD drive where to boot the Windows 8 OS from). UEFI stands for
Unified Extensible Firmware Interface, an interface between the
operating systems and platform firmware during the start-up process.
2. When Boot Option #1 is set to UEFI, there will be 4 partitions in the
HDD shown in the Windows Setup screen as can be seen in the picture
below.

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.
