Introduction
MB500 Product Features
The MB500 Mini ITX motherboard incorporates the AMD Geode LX
processor with speeds of 433MHz (LX700) or 500MHz (LX800). As of
this writing, it comes with two board versions, namely:
MB500 - AMD Geode LX700, 433MHz, Mini ITX mot herboard w/
VGA, 10/100 LAN, CF
MB500F - AMD Geode LX800, 500MHz, Mini ITX motherboard
w/ VGA, dual 10/100 LAN, CF
The AMD Geode™ LX 800@0.9W processor delivers the most
performance per watt in the industry today, providing x86 power and
versatility to applications for entertainment, business, education, and
embedded markets. Its innovative architecture and high level of
integration enables small form-factor designs. The AMD Geode
LX700@0.8W processor delivers great performance at lower power for
value, embedded applications, while delivering full x86 functionality.
MB500 FEATURES:
• Supports AMD Geode LX, 433MHz (LX700) / 500MHz
(LX800)
• DDR DIMM x 1, Max. 1GB memory
• One or two Realtek RTL8100C 10/100 Ethernet
• Integrated LX800/LX700 2D VGA controller
• Supports VGA CRT and TFT/LVDS LCD display
• 4x USB 2.0, 4x COM, CompactFlash socket

INSTALLATIONS
Installing the Memory
The MB500 embedded board supports one DDR memory sockets for a
maximum to tal memory of 1G B in DDR memory type. The memor y
module capacities supported are 128MB, 256MB, 512MB and 1GB.
Installing and Removing Memory Modules
To install the DDR modules, locate the memory slot on the embedded
board and perform the following steps:
1. Hold the DDR m odule so t hat the key of the DDR modul e aligns with
those on the memory slot.
2. Gently push the DDR module in an upright position until the clips of
the slot close to hold the DDR module in place when the DDR module
touches the bottom of the slot.
3. To remove the DDR module, press the clips with both hands.

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.

BIOS SETUP
BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports various 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.
MB500 User’s Manual 27
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 Internal 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.
First/Second/Third Boot Device
These fields determine the drive that the system searches first for an
operating system. The options available i nclude Floppy, LS120, HDD-0,
SCSI, CDROM, HDD-1, HDD-2, HDD-3, ZIP100, USB-FDD, LAN,

BIOS SETUP
Swap Floppy Drive
This item allows you to determi ne whether or not to enable Swap Floppy
Drive. When enabled, the BIOS swaps floppy drive assignments so that
Drive A becomes Drive B, and Drive B becomes Drive A. By default,
this field is set to Disabled.
Boot Up Floppy Seek
This feature controls whether the BIOS checks for a floppy drive while
booting up. If it cannot detect one (either due to improper configuration
or its absence), it will flash an error message.
Boot Up NumLock Status
This allows you to activate the NumLock function after you power up
the system.
Gate A20 Option
This field allows you to select how Gate A20 is worked. Gate A20 is a
device used to address memory above 1 MB.
Typematic Rate Setting
When disabled, continually holding dow n a key on your keyboard will
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.

PM Timers and IRQ Wakeup Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can
prevent the system from entering a power saving mode or can awaken
the system from such a mode. When an I/O device wants to gain the
attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.
