Introduction
The MB-562 is an all-in-one LPX Pentium MMX computer with an onboard PCI SVGA controller, a PCI Ethernet interface and a PISA
expansion slot (one dedicated PISA slot for PCI/ISA riser card option).
Equipped with 64 bits and local bus architecture, the MB-562 releases
Pentium's full potential and provides unprecedented performance
compared to current 32-bit processor boards. Supports Intel Pentium
P54C/P55C(MMX), AMD K5/K6, and Cyrix M1/M2 CPUs. The MB562 offers all the functions of an industrial computer on a single board,
but fits in the space of LPX form factor (only 225mm x 220mm). For
maximum performance, the MB-562 also supports 2nd level cache sized
512 KB.
On-board features include four serial ports (three RS-232 and one RS232/422/485), one multi-mode parallel (ECP/EPP/SPP) port, a floppy
drive controller, and a keyboard/PS/2 mouse interface. The built-in
high-speed PCI IDE controller supports both PIO bus master and Ultra
DMA/33 modes. Up to four IDE devices can be connected, including
large hard disks, CD-ROM drives, tape backup drives, and other IDE
devices.
The MB-562 also features power management to minimize power
consumption. It complies with the “Green Function” standard and
supports three types of power-saving features: Doze mode, Standby
mode, and Suspend mode. In addition, the board’s watchdog timer can
automatically reset the system or generate an interrupt in case the
system stops due to a program bug or EMI.

Setting jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To “close” a
jumper, you connect the pins with the clip. To “open” a jumper, you
remove the clip. Sometimes a jumper will have three pins, labeled 1,
2, and 3. In this case, you would connect either pins 1 and 2 or 2 and 3.

OpenClosedClosed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for your
application, contact your local distributor or sales representative
before you make any changes.
Generally, you simply need a standard cable to make most connections.

CPU installing and upgrading
Y ou can upgrade to a higher power Pentium CPU at any time. Simply
remove the old CPU, install the new one, and set the jumpers for the
new CPU type and speed.
Warning! Always disconnect the power cord from your chassis
when you are working on it. Do not make connections
while the power is on, as sensitive electronic components can be damaged by the sudden rush of power.
Only experienced electronics personnel should open
the PC chassis.
Caution!Always ground yourself to remove any static charge
before touching the PC board. Modern electronic
devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place
all electronic components on a static-dissipative
surface or in a static-shielded bag when they are
not in the chassis.
When you install a new CPU, be sure to adjust the board settings,
such as CPU type and CPU clock. Improper settings may damage
the CPU.

in the middle connects to the B: drive.
3. If you are connecting a 5¼" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connector .
If you are connecting a 3½" floppy drive, you may have trouble
determining which pin is pin number 1. Look for a number printed on
the circuit board indicating pin number 1. Also, the connector on the
floppy drive connector may have a slot. When the slot is up, pin
number 1 should be on the right. Check the documentation that came

Installing DRAM (SIMM1, SIMM2, DIMM1)
The MB-562 LPX Mainboard provides two 72-pin SIMM (Single Inline Memory Module) sockets and one 168-pin DIMM (Dual-in-line
Memory Module). The SIMM supports either Fast Page Mode (FPM)
or Extended Data Output (EDO) DRAM with a speed of at least 70 ns.
The DIMM supported by this mainboard are always 64-bit wide
SDRAM (Synchronous DRAM). Depending on the combination of
modules you use, you can install from 8 MB to 128 MB of RAM.
Warning: SDRAM operates at 3.3V while SIMM (FPM/EDO) modules
operate at 5V. Unless you have 5V tolerance SDRAM, DONOT use SIMM and SDRAM DIMM at the same time.
Installing SIMMs & DIMM
NOTE 1: Pentium or compatible processors adopt 64 bit data bus.
Since 72-pin SIMM can only provide 32 bit data bus width,
two SIMM modules are required as one memory bank, and
both SIMMs must be the same size and type.
1. Ensure that all power sources are disconnected.
2 . Slip the memory module into the socket at a 45 degree angle.
3. Push the module toward the vertical posts at both ends of the
socket until the module is upright and the retaining clips at both
ends of the module click into place. When positioned correctly, the
pins on top of the vertical posts should correspond to the circular
holes on the ends of the module.
4 . Repeat steps 2 and 3 for each module you install.
NOTE 2: Do not insert any SIMM that contains more than 24
memory chips. SIMMs contain more than 24 chips exceed
the driving capability of new generation chipsets.

AT Power Connector (CN1)
The following table lists the pin assignments for the Power Connector:
Y ou can connect your USB (Universal Serial Bus) devices to the USB
connectors. With USB, there is no need to have separate connectors
for keyboards, modems, and mice. USB provides a common interface
for all your peripherals.
Keyboard and PS/2 mouse connectors
(KB/down, MS/up)(CN4)
The MB-562 board provides a keyboard connector and a PS/2 mouse
connector. In most cases, especially in embedded applications, a
keyboard is not used. The standard PC/AT BIOS will report an error or
fail during power-on self-test (POST) after a reset if the keyboard is not
present. The MB-562's BIOS standard setup menu allows you to select
"All, But Keyboard" under the "Halt On" selection. This allows nokeyboard operation in embedded system applications without the
system halt under POST (power-onself-test).

IDE hard drive connectors (CN5, CN6)
You can attach one to four Enhanced Integrated Device Electronics
hard disk drives to the MB-562 internal controller. The MB-562's IDE
controller uses a PCI local-bus interface. This advanced interface
supports faster data transfer and allows the IDE hard drive to exceed
528 MB.
Connecting the hard drive
Connecting drives is done in a daisy-chain fashion and requires one of
two cables, depending on the drive size. 1.8" and 2.5" drives need a 1 x
44-pin to 2 x 44-pin flat-cable connector for CN6. 3.5" drives use a 1 x
40-pin to 2 x 40-pin connector for CN5.
Wire number 1 on the cable is marked as red or blue, and the other
wires are gray.
1 . Connect one end of the cable to CN5 or CN6. Make sure that the
red (or blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).
2 . Plug the other end of the cable to the Enhanced IDE hard drive,
with pin 1 on the cable corresponding to pin 1 on the hard drive.
(See your hard drive's documentation for the location of the
connector.)
Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master
and one as the slave by using jumpers on the drives. If you install just
one drive, set it as the master.

This chapter provides information about:
• Driver types and installation
• Software utility installation and use
Chapter 5 Flat Panel/ CRT Controller 49
Software drivers
This chapter describes the operation and installation of the software
drivers supplied on the Display Driver Diskettes that are shipped with
your VGA adapter.
Y our VGA adapter is based on the CHIPS VGA Flat Panel/CR T
controller and is fully IBM VGA compatible. This controller offers a
large set of extended functions and higher resolutions. If you intend to
use your VGA adapter in standard VGA modes only , you do not need
to install any of these drivers. Since your VGA adapter is fully compatible, it does not require any special drivers to operate in standard
modes.
The purpose of the enclosed software drivers is to take advantage of
the extended features of the CHIPS VGA Flat Panel/CR T controller.
Hardware configuration
Some of the high-resolution drivers provided in this package will
work only in certain system configurations. If a driver does not
display correctly, try the following:
1. Change the display controller to CRT-only mode, rather than flat
panel or simultaneous display mode. Some high-resolution drivers
will display correctly only in CR T mode.
2. If a high-resolution mode is not supported on your system, try
using a lower-resolution mode. For example, 1024 x 768 mode will
not work on some systems, but 800 x 600 mode is supported on
most.

Necessary prerequisites
The instructions in this manual assume that you understand elementary concepts of MS-DOS and the IBM Personal Computer. Before you
attempt to install any driver or utility, you should:
• Know how to copy files from a floppy disk to a directory on the hard
disk
• Understand the MS-DOS directory structure
• Know how to format a floppy disk
If you are uncertain about any of these concepts, please refer to the
DOS WindowsÔ 95 or OS/2 user reference guides for more information before you proceed with the installation.
Before you begin
Before you begin the driver software installation, you should make
backup copies of the Display Driver Diskettes. Store the original
disks in a safe place.

System test and initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds of
errors: fatal and non-fatal. The system can usually continue the boot
up sequence with non-fatal errors. Non-fatal error messages usually
appear on the screen along with the following instructions:
press <F1> to RESUME
Write down the message, and press the F1 key to continue the bootup
sequence.
System configuration verification
These routines check the current system configuration against the
values stored in the card’s CMOS memory. If they do not match, the
program outputs an error message. Y ou will then need to run the BIOS
setup program to set the configuration information in CMOS memory .
There are three situations in which you will need to change the CMOS
settings:
1 . Y ou are starting your system for the first time.
2. You have changed the hardware attached to your system.
3 . The CMOS memory has lost power and the configuration informa-
tion has been erased.
The mainboard CMOS memory has an integral lithium battery backup.
The battery backup should last ten years in normal service, but when it
finally runs down, you will need to replace the complete unit.

Chipset Features Setup
This section allows you to configure the system based on the specific
features of the installed chipset. This chipset manages bus speeds
and access to system memory resources, such as DRAM and the
external cache. It also coordinates communications between the
conventional ISA bus and the PCI bus. It must be stated that these
items should never need to be altered. The default settings have been
chosen because they provide the best operating conditions for your
system.
The only time you might consider making any changes would be if you
discovered that data was being lost while using your system.
Chapter 6 Award BIOS Setup 73
Auto Configuration
Set this item to Enabled to pre-defined values for DRAM, cache
timing according to CPU type & system clock. Thus, each item value
may display differently depending on your system configurations.

system is in a power down mode.
The following is a list of IRQ, Interrupt ReQuests, which can be
exempted much as the COM ports and LPT ports above can. 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.
