2.2 AMAZING WAYS TO POWER ON THE PC SYSTEM

When the mainboard has been installed successfully, there are several ways to
power on the system. Please read the following description for all the details.

POWER BUTTON

The power button can be programmed by COMS setup program and it has different

features. Please refer to page 3-15 for detail function description.

Note: This power button can not be used to power-on the PC system if the

”Password“ is selected in the "Power On Function" to power on your
system. (please refer to Section 4.8 for the “INTEGRATED
PERIPHERALS“ in the CMOS setup.) However, you can always use the
power button to turn off the power.

¨ KEYBOARD (PASSWORD OR HOT KEY)

This mainboard allows you to use your personal password or a combination of hot

key to power on your PC system. When the jumper setting on JP1 is “Enabled”, the
keyboard OnNow function will be activated. Under this circumstance, this
mainboard will keeps scanning the keyboard status waiting for the correct password
or hot key input even when the system power is off (the stand-by 5V is still working
and the power LED on the keyboard is still active). If you have selected the
Password to power on the PC system in the BIOS setup program, the only way to
power on the PC system will be the correct password. ( you can not use the power
button on the front panel to power on the PC system.) When you have selected the
keyboard hot key to power on the PC system, you will be able to use keyboard hot
key to power on the PC system. ( you can use the power button to power on the PC
system as well.) ( Please refer to Section 4.8.- "Power On function")

When the “Password” and “Hot KEY” is selected, you will have to reboot the PC
system to activate the setting, when you see the POST (Power On Self Test) is
completed, the setting is changed and stored in the CMOS memory. Having finished
the procedure, you may turn the power off and then you can use the keyboard to
power-on the PC system afterward.

In case that you forget the “Password” or “Hot Key”, disconnect the AC power for
30-60 seconds then re-connect the AC power to the PC system, and then you can use
the PW switch to power on the PC system again. Or you may use JP9 setting to clear
the Keyboard password.

VIA 693/693A Twin Processor Mainboard INSTALLATION

2-3

¨ PS/2™ MOUSE (LEFT OR RIGHT MOUSE BUTTON)

If you have a PS/2™ mouse connected to the system, you may change the setup in

the BIOS and use the mouse click to turn on the PC system power. Please refer to
section 4.8 for the BIOS setting

To use the mouse key to turn on the PC system power, the mouse click must be done
quickly and continually. Basically, 2-5 quick clicks on the mouse key ( left key or
right key ) will turn the power immediately.

In order to activate the mouse key feature, you will have to reboot the PC system
after the BIOS setting and wait until the POST (Power On Self Test) is completed.
Having finished the procedure, you may use the mouse key to power-on the PC
system afterward..

Note: 1. This feature is not available on the COM port mouse (serial mouse).

2. To use the PS/2 mouse power-on the PC system, JP1 must me "Enabled"

¨ RTC ALARM

PC system can be waked up by the RTC setting in the CMOS. You can set the

alarming date and time in the RTC memory, When RTC alarms, the PC system will
be triggered and wakes up automatically on the date and time which you selected in
the BIOS setup program.

Enable the “Resume by Alarm” selection in the BIOS setup utility, and then you
will see the input request for the date and time. (the “Resume by Alarm” is located
in the “POWER MANAGEMENT SETUP”, please refer to Section 4.7), When you
have stored the RTC alarm setting, the PC system will be turned on automatically
according to the date and time which is recorded in the CMOS memory.

¨ MODEM RING-IN

Everyone knows that a PC system can be used as a fax machine to send or receive

fax messages. But most people still use fax machine to receive their messages
because it is not practical to have the system powered on all day long waiting for
the incoming messages. Now the problem can be solved because this mainboard can
be triggered by a modem ring-in signal.

VIA 693/693A Twin Processor Mainboard INSTALLATION

2-4

When you have a external modem installed, you can leave the PC system power

off. Whenever there is the incoming message, the PC system will be triggered by
the ring-in signal and wake up automatically to receive the message for you. From
now on, you can tell your PC system to receive the fax message for you.

In order to use the ring-in signal to wake up your PC system, you will have to use
the EXTERNAL MODEM and have it connected to one of the SERIAL PORTS

( COMA or COM B ) on the mainboard. When the mainboard detects the ring-in

signal from the serial port, the system power will be turned on and start to receive
the incoming messages automatically. ( you need to have the software like Award
Zero-Volt Data-Suspend Utility so that you can use the fax utility to receive the
incoming fax message ).

To enable the Modem Ring-In feature, you have to run the BIOS setup utility and
enable the “Power On by Ring / LAN” option (it is located in the “POWER
MANAGEMENT SETUP”, please refer to Section 4.7 for the settings).

Note: This function is not available when using the internal MODEM card.

¨ WAKE ON LAN ( WOL )

There is a WOL connector CN16 on the mainboard which is designed to connect to
the signal from a LAN card which supports the Wake On LAN feature. When such
LAN card is installed, you may turn on the PC system from the remote server and
monitor the PC status. To enable this feature, you will have to use the BIOS setup
utility to enable the “Resume by Ring or LAN” in the BIOS setup program.

Note: This function will be disabled if you turn off the power before the system

can verify the DMI pool data.

2.3 POWER OFF THE PC SYSTEM

There are two ways to power off the system. They are “Shut Down by Power Button”
and “ Shut Down by OS”. (such as Windows® 95 and Windows® 98, you can choose
the Shut Down from the file menu and the system will be powered off immediately ).

3. Re-connect the AC power cable.

(F) JP11: CPU Voltage Adjustment

(Optional)
JP11 is designed for some special purpose. Sometimes you may feel that the CPU
voltage detected by the mainboard can not meet your requirement and you want
your CPU core voltage become a little bit higher than regular setting. JP11 is
designed to adjust the CPU voltage. When "SHORT" is selected, the CPU voltage
will be 0.05V higher than normal voltage.

OPEN: Normal Default Setting.

SHORT : CPU Voltage 0.05V increased.

Note: When you use JP11 to raise the CPU voltage, it does not

mean that CPU over clock is guaranteed!.

VIA 693/693A Twin Processor Mainboard INSTALLATION

3-18

(G) JP12: CPU Voltage Range Selection (Optional)

JP12 is a special design on the mainboard. JP12 allows you to select the CPU core
voltage range (Vcore) to protect the CPU.

The voltage regulator on the mainboard will generate 1.3V ~ 3.5V DC to support
different processors. Basically, most mainboards will use the CPU VID signal
(VID0~VID4) from the CPU to decide the proper CPU core voltage (Vcore). In
case that there is the poor connection between CPU and its socket, or uninstall the
CPU from the mainboard while the system power is "ON". Under such
circumstance, mainboard may receive wrong VID signal and send wrong Vcore to
the CPU. Unfortunately, wrong Vcore may destroy the CPU and the mainboard.

JP12 is designed to control the Vcore within the safe range so that it won't make
any damage to the CPU or mainbord because of wrong VID signal.

Since most Pentium II/!!! processors require the Vcore below 2.05V except few
Pentium II processors. So the default setting of JP12 will control the Vcore
between 1.3V and 2.05V so that the CPU and mainboard will have a good
protection. Please do not change the setting on JP12 unless your CPU needs the
voltage higher than 2.05V.

OPEN: Vcore = 1.3V ~ 2.05V

SHORT : Vcore = 1.3V ~ 3.5V.

(H) JP100 / JP133: Over Clock Selection

JP100 and JP133 are designed to choose the CPU FSB clock (Front Side Bus
Clock). Basically, when you have installed the CPU onto the mainboard, this
mainboard will detect the CPU type and specify the proper FSB clock for the CPU.
So most of the time you need not to make any setting to select the FSB clock.
However, sometimes you may feel like to select different FSB clock for some
special purpose. In this case, you may use the BIOS setting to select different FSB
clock or use the jumper setting on JP100/JP133 to force your CPU to use the
selected FSB clock.

(Please do not attempt to change this setting unless you are

the technician)

. Please refer to the following for functional description.

This mainboard is designed by using either VIA 693 or 693A chipset. When VIA693 is
installed on the mainboard, you will see only JP100 on the board and you can use it to
tell the mainboard to use the choosen FSB clock in the following table despite the CPU
installed on the mainboard. If you found the VIA693A chipset installed on the
mainboard, then you will see both JP100 and JP133 on the board and you can refer to
the following table to select different FSB clock:

program ( refer to Section. 4-6 ). Please do not to make
jumper setting on JP100 and JP133 unless you are the
professional technician.

2. When "Default" is selected, you may use JP100/JP133 to
select different speed of CPU clock and force your CPU to use
that clock speed instead of letting the system BIOS to select
the CPU clock automatically.

(I) SWITCH SETTINGS

There is one "toggle switch" designed on the mainboard to select the CPU clock
ratio. Basically, you have to check your CPU carefully because some of the CPU
does not allow you to change its default clock ratio setting. In another word. the
switch setting on the mainboard will make no change when you are using the
processor whose clock ratio is "specified and locked" inside the CPU.

you wish to use it. However, if you have another USB controller on one of the add
on card, you will have to disable this feature.

USB Keyboard Support: (default setting : "Disabled".)

Select "Enabled" in this field will allow operation system to use the USB
keyboard. If there is no USB keyboard connected to the PC system, leave it
"Disabled".

Auto Detect DIMM/PCI Clk: (default setting : “Enabled” )

When “Enabled” is selected, the mainboard will detect the presence of devices on
DIMM and PCI slots. When there is no device presented, the clock on the related
DIMM and PCI slot will be disabled to reduce the electro magnetic interference
(EMI).

CPU Host/ PCI Clock: (default setting: “Default” )

This selection field is used to decide the CPU FSB clock. Basically, this mainboard
is designed by Intel VIA 693/693A AGPset and it supports both the 100MHz and
66MHz FSB frequency. When you select “default” setting, the system BIOS will
detect the CPU type and decide the FSB clock automatically. You may also use this
field to select different FSB clock and force your CPU to run at higher speed. ( be
sure to make sure your system devices are fast enough before you can change to
such setting)

When you have decided the FSB clock, you will have to use toggle switch (SW)
setting to select the CPU clock ratio and decide the CPU speed. please refer to page
3-23 for details of the switch settings..

Beside the "Default" FSB selection, this mainboard also provides the manual
option for your choice. You may use th "Page Up" and "Page Down" to select
different FSB clock, the FSB selectable in the BIOS are: 66, 75, 83, 100, 103, 112,
124, 133 and 140 MHz.

Note:

1. The higher FSB frequency will surely give you the higher
system performance. However, it is not recommended because
it may cause the system unstable, especially the component
like DRAM, HDD, Add on card is not fast enough.

2. Wrong selection of FSB clock may cause the PC system
hangup and the system can not boot, In case that it should be
happened, please use JP9 to clear the CMOS so that you can

When the ACPI function is installed in your PC system successfully, you will find
the ACPI function in the power management icon. The PW switch (mentioned in
Section 3) defined by the ACPI is different to the BIOS setup and it always has
the higher priority than what was defined in the system BIOS.
According to what was defined by the ACPI in Windows 98, the PW switch can
be either the "Standby switch" or "shutdown switch". When "Standby switch" is
selected, the first click on the PW switch will have the PC system turn into
standby mode. If you want to "wake up" the PC system, you will have to use the
devices (such as keyboard, mouse .. etc) which is specified in the Windows 98
ACPI function to trigger the PC system so that it will be back to full-on mode. For
more detail of ACPI function, please refer to Windows 98 user's manual for more

requirement. If you do not have the related technical background, do
not attempt to make any change.

PNP OS Installed :

( Default setting is “No” )
The setting in this field tells the system BIOS whether your operating system (OS) is a
PnP OS (such as Windows® 95 and Windows® 98) or not. The PnP OS will use the
system resources record stored in the ESCD segment to arrange the system
environment..

Resources Controlled by : (Default setting: Manual)

VIA 693/693A Twin Processor Mainboard AWARD BIOS SETUP

4-16

Manual : The system BIOS will not refer to the ESCD data to assign IRQ & DMA.

Instead, it will refer to the information recorded in this field when
Assigning the IRQ & DMA resource. ( the system BIOS will always
refer to the ESCE data to assign the I/O and memory space resources ).

Auto : The system BIOS will refer to the ESCD segment for all legacy information.

Reset Configuration Data :

Disabled : The system BIOS will do nothing.
Enabled : The system BIOS will clear (reset) the ESCD data during “POST”. After

clearing the ESCD data, the system BIOS will then change this item‘s
value back to “Disabled”, otherwise, the ESCD data will become useless.

IRQ# / DMA# assigned to :

There are only 15 IRQs and 8 DMAs available on the mainboard and most of them
are assigned for some specific purposes. Sometimes, user may feel like to have
some more IRQ and DMA in order to install the new add on cards. In this case, you
may use this field to assign some of the IRQ and DMA to “PCI/ISA PnP” so that
the new add on card will find the free IRQ or DMA available for it.

Legacy : The system BIOS will skip and never assign the specified IRQ/DMA
ISA resource to PCI or ISA PnP devices and the IRQ and DMA can only be sued

by their specified Legacy ISA cards.

PCI/ISA: When “PCI/ISA PnP” is selected, the related IRQ and DMA will be
PnP released and they can be used by other PCI or ISA devices. Whenever

there is the new PCI or ISA devices plugged onto the mainboard, system
BIOS will detect it and assign a free IRQ or DMA for the new devices.

.Note: Most IRQ and DMA have its own purpose and they can not be assigned to

“PCI/ISA PnP”. For example, IRQ14 and IRQ15 is used by the onboard IDE
device. If you change the setting on IRQ14 and IRQ15, you will be unable to
connect the hard disk drive or CD ROM drive to the IDE interface on the
mainboard. So please make sure to check the IRQ and DMA arrangement in
your system before you proceed to do the setting. For instance, if you do not
have the printer (IRQ7) or PS/2™ mouse (IRQ12) connected to your PC
system, you may assign IRQ7 and IRQ12 to “PCI/ISA PnP” so that you can
have more IRQs available for new add on cards.

CPU to PCI Write Buffer : (Default Setting : Enabled)

When enabled, up to four Dwords of data can be written to the PCI bus without
interrupting the CPU. When disabled, a write buffer is not used and the CPU read
cycle will not be completed until the PCI bus signals is ready to receive the data.

PCI Dynamic Bursting : (Default Setting : Enabled)

When

Enabled, every write transaction goes to the write buffer. Burstable

transactions then burst on the PCI bus and nonburstable transactions don’t.

PCI Master 0 WS Write : (Default Setting : Enabled)

When

Enabled, writes to the PCI bus are executed with zero wait states.

PCI Delay Transaction : (Default Setting : Enabled)

The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select Enabled to support compliance with PCI specification
version 2.1.

PCI#2 Access #1 Retry : (Default Setting : Disabled)

This item allows you enable/disable the PCI #2 Access #1 Retry.

AGP Master 1WS Write / Read

This implements a single delay when writing / reading to the AGP Bus. By default,
two-wait states are used by the system, allowing for greater stability.

Assign IRQ For VGA/USB

The system’s IRQ signals are limited and sometimes you may feel like to some
more IRQ signals for your add-on cards. The system BIOS allows you to disable
the IRQ which is supposed to be connected to VGA and USB ports. When you
have choose to disable the IRQ on VGA or USB port, the IRQ on the related IRQ
will be released and becomes available for other devices.

Before you can proceed with the change, please make sure that you do not have
USB and VGA adapter which will use the IRQ signal. Otherwise, your PC system
will become abnormal and the devices connected to these ports will be failed.

VIA 693/693A Twin Processor Mainboard AWARD BIOS SETUP

4-18

It is very simple to tell the difference. If you are going to disable the IRQ on the
USB port, check whether is any device connected to the USB port. If you can not
find any device, you may feel free to disable the IRQ on the USB port and have the
IRQ used by other device.

As for VGA adapter, it will be a little difficult. You may try to find whether your
VGA card requires the IRQ signal or not. If you can not find the information from
the user’s manual of your VGA card. You may use the following information to
make your choice:

1.

Most VGA cards do not need to have the IRQ signal.

2.

If you can not find the feature connector on your VGA card, than it is quite

possible that your VGA card does not need the IRQ signal.

3.

If your VGA card has the feature connector on the VGA card but it has

nothing connected to it. In this case, you still may have the IRQ disabled.

4.

If you have another add on card like video capture card which is connected

to the feature connector on the VGA card, In this case, you can not disable
the IRQ signal because the IRQ signal will be connected to the video
capture card.

Note : No matter what is defined in the “Resources Controlled By” field (“Manual” or

“Auto”), the system BIOS will always assign IRQ resources to PCI devices
from the highest one first ( ie. IRQ15, 14, 13 …) while assign IRQ resources to
ISA PnP devices from the lowest one first ( ie. IRQ3,4,5 .. ).

There are so many different types of Hard Disk Drive (HDD) in the market and your PC
system will not know the HDD type unless you tell it the HDD type. In order to make
your PC system know the IDE HDD type, you have to tell the system what kind of
HDD is connected to the mainboard by giving a set of HDD parameters. Sometimes it
is not easy for users to find the proper parameters for their IDE HDD. In order to help
users to find the parameters, the system BIOS provides a convent way – the auto
detection of IDE HDD.

To run the auto detection program is extremely easy. Move the selection bar to “IDE
HDD AUTO DETECTION” and then press “Enter”, the system BIOS take over the job
and try to detect the type of IDE HDD. If it succeeds, you will see a list of hard disk
with its related parameters displayed on the screen. You may press on the “Y” key to
