INSTALLATIONS
Installing the Memory
The MB837-D25 board supports one DDR3 memory socket that can support
up to 4GB memory, DDR3 1066/1333 (w/o ECC function).
Installing and Removing Memory Modules
To install the DDR3 module, locate the memory slot on the board and perform
the following steps:
1. Hold the DDR3 module so that the key of the DDR3 module aligns with that
on the memory slot. Insert the module into the socket at a slight angle
(approximately 30 degrees). Note that the socket and module are both keyed,
which means that the module can be installed only in one direction.
2. To seat the memory module into the socket, apply firm and even pressure to
each end of the module until you feel it slip down into the socket.
3. With the module properly seated in the socket, rotate the module downward.
Continue pressing downward until the clips at each end lock into position.
4. To remove the DDR3 module, press the clips with both hands.

BIOS Setup
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.
16
MB837-D25 / MB837-D25-R User’s Manual
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.

C. 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.
