Hardware Installation

2-1 Unpacking

This mainboard package should contain the following:

•

The MTX-A512 mainboard

•

USER’S MANUAL for mainboard

•

Cable set for IDE x1, Floppy x1, COM1 & COM2 x1, LPT & PS/2 Mouse x1,

VGA x1

•

Diskette for Drivers

The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original packing
until it is installed.

Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the same

point as the anti-static mat.
Inspect the mainboard carton for obvious damage. Shipping and handling may

cause damage to your board. Be sure there are no shipping and handling damages
on the board before proceeding.

After opening the mainboard carton, extract the system board and place it only on
a grounded anti-static surface component side up. Again inspect the board for
damage.

Press down on all of the socket IC’s to make sure that they are properly seated. Do
this only on with the board placed on a firm flat surface.

Warning: Do not apply power to the board if it has been damaged.

You are now ready to install your mainboard. The mounting hole pattern on the
mainboard matches the IBM-AT system board.

It is assumed that the chassis is designed for a standard IBM XT/AT mainboard
mounting. Place the chassis on the anti-static mat and remove the cover.

Take the plastic clips, Nylon stand-off and screws for mounting the system board,
and keep them separate.

This mainboard support four 72-pins SIMM module socket & two 168 pins DIMM
module socket, because of the memory controller it can support 4 banks of double
sided SIMMs maximum and 3 banks of double sided DIMM maximum. So that

MTX-A512 can support any combination of DRAM up to 512MB on board and

without any constraint.

2-7 Central Processing Unit (CPU)

The motherboard provides a 321-pins ZIF Socket 7. The CPU on mother board
must have a fan attached to prevent overheating.

WARNING: Without a fan, the CPU will be overheat and cause damage to both the

CPU and the motherboard.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree right angle. Insert the CPU with the white dot as your guide.
The white dot should point towards the end of the level. The CPU has a corner pin
for three of the four corners, the CPU will only fit in the one orientation as shown as
follow. With the added weight of the CPU fan, no force is required to insert the CPU.
Once completely inserted, hold down on the fan and close the socket’s lever.

IMPORTANT: You must set SW1 “DIP Switch for CPU Type Selection” on page 6 and jumper

JP4 “CPU Voltage Selection” on page 6 depending on the CPU that you install.

2-8 Expansion Cards

First read your expansion card documentation on any hardware and software
settings that may be required to setup your specific card.

11

Installation Procedure:

1. Read the documentation for your expansion card.

2. Set any necessary jumpers on your expansion card.

3. Remove your computer’s cover.

4. Remove the bracket on the slot you intend to use.

5. Carefu lly align the card’s connectors and press firmly.

6. Secure the card on the slot with the screw you remove in step 4.

7. Replace the computer’s cover.

8. Setup the BIOS if necessary.

9. Install the necessary software drivers for your expansion card.

Assigning IRQs for Expansion Cards

Some expansion cards may require an IRQ to operate. Generally an IRQ must be
exclusively assigned to only one device. In an standard design there are 16 IRQs
available but most of them are occupied by the system and leaves 6 free for
expansion cards.

Either ISA or PCI expansion cards may require an IRQs. System IRQs are available
to cards installed in the ISA expansion first, and any remaining IRQs can be used
by PCI cards. Currently, there are two types of ISA cards. An original ISA expansion

card design, know as “Legacy” ISA cards, they request configure the card’s jumpers

manually and then install it in any available slot on the ISA bus, and other know as
Plug and Play. You may u se Microsoft’s Diagnostic (MSD.EXE) utility included in
the DOS directory to see a map of your used and any free IRQs. For Windows 95

users, the “Control Panel” icon in “My Computer”, contains a “System” icon which
gives you “Device Manager” tab. Double clickin g on a specific device give you

“Resources” tab which shows the Interrupt number and address. Make sure that

no any two of devices use the same IRQs, or your computer will experience
problems when those two devices are in use at the same time.

To simplify this process the motherboard has complied with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration
whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are
assigned automatically from those available.

If the system has both Legacy and PNP ISA cards installed, IRQs are assigned to
PNP cards from those not used by Legacy cards. The PCI and PNP configuration
of the BIOS setup utility can be used to indicate which IRQs are being used by

12

Legacy cards. For older Legacy cards that does not work with the BIOS, you can
contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those used
by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically assigns
an IRQ to a PCI. To install a PCI card, you need to set something called the INT
(interrupt) assignment. Since all the PCI slots on this motherboard use an INTA #,
be sure that the jumpers on your PCI cards are set to INT A.

Assigning DMA Channels for ISA Cards

Some ISA cards, both Legacy and PNP may also need to use a DMA (Direct
Memory Access) channel. DMA assignments for this motherboard are handled the
same way as the IRQ assignment process described above. You can select a DMA
channel in the PCI and PNP configuration section of the BIOS Setup utility. In the

BIOS setup, you should choose “Yes” for those IRQ’s and DMA’s you wish to

reserve for Legacy cards.

2-9 External Connectors

1. Power connector: AT Power Connector (12-pins block): CN2

This connector connects to a standard 5 Volt power supply. To connect the
leads from the power supply, ensure first that the power supply is not plugged.
Most power supplies provide two plugs (P8 and P9), each containing six wires,
two of which are black. Orient the connectors so that the black wires are located
in the middle.

Using a slight angle, align the plastic guide pins on the lead to their receptacles

on the connector. Once aligned, press the lead onto the connector until the lead
locks into place.

AWARD BIOS SETUP

Award's ROM BIOS provides a built-in Setup program which allows user modify the
basic system configuration and hardware parameters. The modified data will be
stored in a battery-backed CMOS RAM so data will be retained even when the
power is turned off. In general, the information saved in the CMOS RAM stay
unchanged unless here is configuration change in the system, such as hard drive
replacement or new equipment is installed.

It is possible that CMOS had a battery failure which cause data lose in CMOS-RAM.
If so, re-enter system configuration parameters become necessary.

Management is set to 'User Define'.

3-4-1 The Description of the Power Management

This motherboard supports HDD Power Down, Doze and standby power saving
functions when Intel Pentium Processor CPU is installed. The suspend function is
also supported when the SMI switch is short. The detail description of these
functions are provided as following:

•

Power Management mode selection:

Disabled

:

The system operates in NORMAL conditions (Non-GREEN),

and the Power Management function is disabled.
Max.saving: This mode will maximize the power saving capability.
Min.saving

:

This mode will minimize the power saving capability.

28

User define: Allow user to define time-out parameters to control power saving.

Refer item shown below:

•

Time-out parameters:

HDD Power Down

HDD Power Down timer can be set from 1 to 15 minute(s). When system stop
reading or writing HDD, the timer starts to count. The system will cut off the HDD
power when timer ran out of time. The system will not resume operation until either
a read from; or a write to HDD command is executed again.

Doze Mode

The "System Doze" mode timer starts to count when there is no "PM events"
occurred. The valid timeout setting is from 1 minute up to 1 hour. The system
hardware will drop down CPU clock from normal working speed when Doze mode
time-out occurred.

Standby Mode

The "Standby" mode timer starts to count when "System Doze" mode timer timed
out and no "PM events" occurred. Valid range is from 1 minute up to 1 hour. When
the system standby mode timer ran out, it will enter the standby mode and retain
CPU at slow working speed. The screen will be blanked out.

Suspend Mode

This function works only when the Pentium CPU is installed. The timer starts to
count when "System Standby" mode timer timed out and no "PM Events" occurred.
Valid range is from 1 minute up to 1 hour. When the system suspend timer time out,
the system will enter the suspend mode and the chipset will stop CPU clock
immediately. The power consumption in Suspend Mode is lower than in standby
mode. The screen is also blanked out.

•

Video Off Method

This field defines the video off features. Three options are available:

V/H SYNC +

Blank, DPMS and Blank Only

. The first option, which is the default setting, blanks

the screen and turns off vertical and horizontal scanning; “DPMS” (acronym for

Display Power management System) allows the BIOS to control the video display

card if it supports the DPMS feature; “Blank Only” only blanks the screen. Use the

latter for monitors that do not support the “Green” feature.

Take note that a screen saver software does not work with this feature. While the
monitor is shut off, this software cannot display.

29

Standby Events:

The user can initial any Standby Events to be "Enabled" or "Disabled". When the
system detects all of the Enabled events do not have any activity, it will start the
system Doze timer first, if the "Power Management" isn't "Disabled". Once the
system Doze timer timed out, it will process doze power saving procedure by
starting the system standby timer. When the standby timer ran out and all of the
"Enabled" events remains silent, the system will enter the standby mode.

•

Power Button (Power Off):

This function allows user to set Power Button as
Power on/off function or SMI function. When setting power off touch power
button will power on or power off. When setting Green Mode, touch the button
the system will enter Suspend Mode, touch the button again will wake up
system, if press the button more than 4 sec the system will power off.

PNP OS Installed (No):

When selected Yes, interrupts may be reassigned by
the OS when Plug and Play operating system (OS) are installed. When a non­plug and play OS is installed or to prevent reassigning of interrupt settings,
please select No.

IRQxx assigned to

These fields indicate whether or not the displayed IRQ for each field is being used
by a Legacy (non-PnP) ISA card. Two options are available: “PCI/ISA PnP” and

“Legacy ISA”. The first option the default value, indicates either that the displayed

IRQ is not used or an PCI/ISA PnP is being used to determine if an ISA card is
using that IRQ. Second option is for Legacy ISA card that requires a unique IRQ,
and you are not using an PCI/ISA PnP, you must set the field for that IRQ to Legacy
ISA.

For example: If you install a Legacy ISA card that requires IRQ10 lets say, then set
“IRQ10 assigned to Legacy ISA”.

DMAxx assigned to

These fields indicate whether or not the displayed DMA channel for each field is
being used by a Legacy (non-PnP) ISA card. Available options include: “PCI/ISA

PnP” an d ”Legacy ISA“. When is option ”PCI/ISA PnP“ indicates either that the

displayed DMA channel is not used or an PCI/ISA PnP being used to determine if
an ISA card is using that channel. If you install a Legacy ISA card that requires a
unique DMA channel, and you are not using an PCI/ISA PnP, you must set the field
for that chan nel to “Legacy ISA“.

3-9 SUPERVISOR/USER PASSWORD

This item lets you configure the system so that a password is required each time
the system boots or an attempt is made to enter the Setup program (Refer to Figure
3-3 for the details). Supervisor Password allows you to change all CMOS settings
but the User Password setting doesn’t have this function. The way to set up the
passwords for both Supervisor and User are as follow:

1. Choose either Supervisor Password or User Password in the Main Menu and

press <Enter>. The following message appears:

“

Enter Password:”

2. The first time you run this option, enter your password up to only 8 characters

and press <Enter>. The screen does not display the entered characters. For
no password just press <Enter>.

3. After you enter the password, the following message appears prompting you to

confirm the password:

“

Confirm Password:

”

4. Enter exact the same password you just typed again to confirm the password

and press <Enter>.

5. Move the cursor to Save & Exit Setup to save the password.

6. If you need to delete the password you entered before, choose the Supervisor

Password and Press <Enter>. It will delete the password that you bad before.

7. Move the cursor to Save & Exit Setup to save the option you did, otherwise the

old password will still be there when you turn on your machine next time.

3-10 IDE HDD AUTO DETECTION

35

The "IDE HDD AUTO DETECTION" utility is a very useful tool especially when you
do not know which kind of hard disk type you are using. You can use this utility to
detect the correct disk type and install in the system automatically. Also you can

set HARD DISK TYPE to “Auto” in the STANDARD CMOS SETUP to have same

result. The BIOS will Auto-detect the hard disk size and model on display during
POST.

NOTE: HDD Modes
The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE

NORMAL mode

Generic access mode in which neither the BIOS nor the IDE controller will make
any transformations during accessing.

The maximum number of cylinders, head & sectors for NORMAL mode are 1024,
16 & 63.
no. Cylinder (1024)
x no. Head ( 16)
x no. Sector ( 63)
x no. per sector ( 512)
528 Megabytes

If user set this HDD to NORMAL mode, the maximum accessible HDD size will be
528 Megabytes even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode

Se lect Secondary Slave Option (N=Skip):N

OPTIONS SI ZE C Y LS H E AD P R ECOMP LANDZ S E CTOR MODE

1 (Y ) 0 0 0 0 0 0 N ORMAL

36

A new HDD accessing method to overcome the 528 Megabyte bottleneck. The
number of cylinders, heads & sectors shown in setup may not be the number
physically contained in the HDD.

During HDD accessing, the IDE controller will transform the logical address
described by sector, head & cylinder into its own physical address inside the HDD.

The maximum HDD size supported by LBA mode is 8.4 Gigabytes which is obtained
by the following formula:

no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x bytes per sector ( 512)

8.4 Gigabytes

LARGE mode

Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some

cases, user do not want LBA). The Award BIOS provides another alternative to
support these kinds of LARGE mode:

CYLS. HEAD SECTOR MODE
1120 16 59 NORMAL
560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiply by 2. Reverse
transformation process will be made inside INT 12h in order to access the right
HDD address the right HDD address!
Maximum HDD size:

no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)
1 Gigabytes

NOTE: To support LBA or LARGE mode of HDDs, there must be some softwares

involved. All these softwares are located in the Award HDD Service Routine
(1NT 13h). It may be failed to access a HDD with LBA (LARGE) mode selected
if you are running under a Operating System which replaces the whole INT 13h.
UNIX operating systems do not support either LBA or LARGE and must utility
the Standard mode. UNIX can support drives larger than 528MB.

3-11 SAVE & EXIT SETUP

The "SAVE & EXIT SETUP" option will bring you back to boot up procedure with all
the changes you just made which are recorded in the CMOS RAM.

3-12 EXIT WITHOUT SAVING

The "EXIT WITHOUT SAVING" option will bring you back to normal boot up
procedure without saving any data into CMOS RAM. All of the old data in the CMOS
will not be destroyed.
