Installing the CPU
The MB870 embedded board supports a Socket 478 processor socket for
Intel Pentium 4 processors.
The Socket 478 processor socket comes with a lever to secure the
processor. Raise this lever to about a 90° angle to allow the insertion of
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, return the
lever to the lock position. Refer to the figures below.
After you have installed the processor into the socket, check if the
jumpers for the CPU type and speed are correct.
NOTE:
Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.

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 Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel Pentium 4 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
ch
anges 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
34 MB870 User’s Manual
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.

Virus Warning
This item protects the boot sector and partition table of your hard disk
against accidental modifications. If an attempt is made, the BIOS will
halt the system and display a warning message. If this occurs, you can
either allow the operation to continue or run an anti-virus program to
locate and remove the problem.
CPU L1/L2 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.
BIOS SETUP
38 MB870 User’s Manual
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.

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 down 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.
BIOS SETUP
MB870 User’s Manual 39
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 expandability. The default setting is
1.4.

permanently stored in the BIOS ROM. These default settings are
non-optimal and disable all high-performance features.
Load Optimized Defaults
This option allows you to load the default values to your system
configuration. These default settings are optimal and enable all high
performance features.

These two options set the system password. Supervisor Password sets a
password that will be used to protect the system and Setup utility. User
Password sets a password that will be used exclusively on the system. To
specify a password, highlight the type you want and press <Enter>. The
Enter Password: message prompts on the screen. Type the password, up

your password by asking you to type it again. After setting a password,
the screen automatically returns to the main screen.
To disable a password, just press the <Enter> key when you are
prompted to enter the password. A message will confirm the password to
be disabled. Once the password is disabled, the system will boot and you
can enter Setup freely.

modifications. If you type “Y”, you will quit the setup utility and save all
changes into the CMOS memory. If you type “N”, you will return to
Setup utility.
Exit Without Saving
Select this option to exit the Setup utility without saving the changes you
have made in this session. Typing “Y” will quit the Setup utility without
saving the modifications. Typing “N” will return you to Setup utility.
