INTRODUCTION
Introduction
Product Description
The MB890 Mini ITX board incorporates the Intel® advanced 855GME Chipset
that contains two core components: the Memory Controller Hub (GMCH) and
ICH4. The GMCH integrates a 400MHz Pentium
controller, integrated graphics controller hub, integrated LVDS interface, two
digital video out ports multiplexed with an AGP 4x controller, a 200/266/
333MHz DDR-SDRAM controller.
The ICH4 integrates an Ultra ATA 100/66/33 controller, USB host controller
that supports the USB 1.1 and USB 2.0 specification, LPC interface, FWH Flash
BIOS interface controller, AC’97 digital controller and a hub interface for
communication with the GMCH.
The Pentium M processor is a higher performance, lower power processor with
several microarchitectural enhancements over existing Intel low-power
processors. Some key features of the Pentium M processor microarchitecture
include dynamic execution, data pre-fetch logic, 400MHz source-synchronous
Front Side Bus (FSB), on-die 1 Mbyte second level cache (on-die 512Kbyte
second level cache on Celeron M processor) with advanced transfer cache
architecture, streaming SIMD extensions 2 (SSE2), and Enhanced Intel
SpeedStep technology.
The super I/O W83627THF onboard integrates the following major peripheral
functions in a chip: the disk driver adapter (FDC), serial port (UART), parallel
port (SPP/EPP/ECP), keyboard controller (KBC), SIR, game port, MIDI port,
hardware monitor, ACPI and On Now Wake-up features.
MB890 supports both DVI and optional TV-OUT with the use of the Chrontel
CH7009 (default) or support DVI only with the use of the Chrontel CH7301. The
TV-Out processor performs non-interlace to interlace conversion with scaling
and flicker filters, and encodes the data into any of the NTSC or PAL video
standards.
The MB890 Mini-ITX motherboard supports CRT VGA interface as well. Intel
82541GI supports Gigabit Ethernet functionality. The board also has AC97
5.1CH audio, 2 COM ports, UDMA 100, 6 USB ports, watchdog timer and a PCI
slot for expandability. Dimensions of the board are 170mm x 170mm.

BIOS SETUP
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.

BIOS SETUP
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 motherboard 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.

CPU L1 and L2 Cache / CPU 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. By default, these items are
Enabled.
Quick Power On Self Test
When enabled, this field speeds up the Power On Self Test (POST) after
the system is turned on. If it is set to Enabled, BIOS will skip some
items.

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 sort 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.
