INSTALLATIONS
Installing the Memory
The IB825 board supports two DDR2 memory sockets to support up to
2GB memory, DDR2 400/533 (w/o ECC function).
Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR2 module so that the key of the DDR2 module aligns
with that on the memory slot. Insert the module into the socket at a
slight angle. 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, push the module
downward. Continue pressing downward until the clips at each end
lock into position.
4. To remove the DDR2 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 adds virus and 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.

If the system cannot boot after making and saving system
changes with Setup, the AMI BIOS supports an override to
the CMOS settings that resets your system to its default.
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.
