INTRODUCTION
Introduction
Product Description
The IB882 3.5” disk-size board incorporates the Mobile Intel® Poulsbo Chipset
for Embedded Computing, consisting of the Intel® single-chip system controller
hub (SCH), an optimized integrated graphics solution with a 533MHz and
400MHz front-side bus. Dimensions of the board are 102mm x 147mm.
The integrated powerful 3D graphics engine, based on Intel® Graphics Media
Accelerator) architecture 500, operates at core speeds of up to 200 MHz. It
features a low-power design, With DDR2 533/400MHz one SO-DIMM socket
on board, the board supports up to 1GB of DDR2 system memory.
Intel® Graphics supports a unique intelligent memory management scheme
called Dynamic Video Memory Technology (DVMT). DVMT handles diverse
applications by providing the availability of system memory for general
computer usage, while supplying additional graphics memory when a
3D-intensive application requests it. The Intel graphics architecture also takes
advantage of the high-performance Intel processor. Intel graphics supports Dual
Independent Display technology.
The main features of the board are:
Supports Intel® Atom Z530 (1.6GHz), Z510 (1.1GHz)
Supports up to 533MHz FSB
One DDR2 SDRAM SO-DIMM, Max. 1GB memory
Onboard Two Intel Gigabit LAN
Intel® VGA for CRT (ID398) / LVDS
1x SATA, 8x USB 2.0, 4x COM, Watchdog timer
1x PCI-104 Socket

Installing the Memory
The IB882 board supports a DDR2 memory socket for a maximum total
memory of 1GB in DDR2 533/400 memory type.
Installing and Removing Memory Modules
To install DDR2 modules, locate the memory socket on the board and
perform the following steps:
1. Hold the DDR2 module so that the keys of the DDR2 module align
with those on the memory slot.
2. Gently push the DDR2 module in an angle as shown in the picture
below until the clips of the sockets lock to hold the DDR2 module in
place when the DDR2 module touches the bottom of the socket.
3. To remove the DDR2 module, press the clips with both hands.

BIOS Introduction
The Award 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 Award 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 Award 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.

The section below the setup items of the Main Menu displays the control
keys for this menu. At the bottom of the Main Menu just below the
control keys section, there is another section, which displays information
on the currently highlighted item in the list.
Note:
If the system cannot boot after making and saving system
changes with Setup, the Award 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 Award 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.

Standard CMOS Setup
“Standard CMOS Setup” choice allows you to record some basic
hardware configurations in your computer system and set the system
clock and error handling. If the board is already installed in a working
system, you will not need to select this option. You will need to run the
Standard CMOS option, however, if you change your system hardware
configurations, the onboard battery fails, or the configuration stored in
the CMOS memory was lost or damaged.

If this option is enabled, an alarm message will be displayed when trying

CPU L1 / L2 / L3 Cache
Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on up
contain internal cache memory, and most, but not all, modern PCs have
additional (external) cache memory. When the CPU requests data, the
system transfers the requested data from the main DRAM into cache
memory, for even faster access by the CPU. These items allow you to
enable (speed up memory access) or disable the cache function. By
default, these items are enabled.

generate only one instance. When enabled, you can set the two typematic
controls listed next. By default, this field is set to Disabled.
Typematic Rate (Chars/Sec)
When the typematic rate is enabled, the system registers repeated
keystrokes speeds. Settings are from 6 to 30 characters per second.

Typematic Delay (Msec)
When the typematic rate is enabled, this item allows you to set the time
interval for displaying the first and second characters. By default, this
item is set to 250msec.
Security Option
This field allows you to limit access to the System and Setup. The default
value is Setup. When you select System, the system prompts for the User
Password every time you boot up. When you select Setup, the system
always boots up and prompts for the Supervisor Password only when the
Setup utility is called up.
APIC Mode
APIC stands for Advanced Programmable Interrupt Controller. The
default setting is Enabled.
MPS Version Control for OS
This option is specifies the MPS (Multiprocessor Specification) version
for your operating system. MPS version 1.4 added extended
configuration tables to improve support for multiple PCI bus
configurations and improve future expand ability. The default setting is
1.4.
OS Select for DRAM > 64MB
This option allows the system to access greater than 64MB of DRAM
memory when used with OS/2 that depends on certain BIOS calls to
access memory. The default setting is Non-OS/2.
Report No FDD For WIN 95
If you are using Windows 95/98 without a floppy disk drive, select
Enabled to release IRQ6. This is required to pass Windows 95/98' s SCT
test. You should also disable the Onboard FDC Controller in the
Integrated Peripherals screen when there's no floppy drive i n the system.
If you set this feature to Disabled, the BIOS will not report the missing
floppy drive to Win95/98.
Small Logo (EPA) Show
The EPA logo appears at the right side of the monitor screen when the
system is boot up. The default setting is Disabled.

IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.
On-chip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Select Enabled to activate each channel
separately.
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programmed Input /Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select
the best available mode.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature. The options are Auto and
Disabled.
Power ON Function
This field is related to how the system is powered on – such as with th e
use of conventional power button, keyboard or hot keys. The default is
BUTTON ONLY.

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.
