2-3 Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7. The CPU that came with the
motherboard sould have a fan attached to it to prevent overheating. If this is not
the cae then purchase a fan before you turn on your system.


WARNING: Without a fan, the CPU can overheat and cause damage to both the
CPU and the motherboard.




9
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. 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 jumpers JP13 & JP14 "CPU to Bus frequency Ratio" on
and jumpers J5 "Bus Frequency Selection" on page 4 depending on
the CPU that you install.

2-4 Expansion Cards
First read your expansion card documentation on any hardware and software
settings that may be required to setup your specific card.

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. Carefully 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.

10
Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally an IRQ must
be exclusively assigned to one use. In an standard design three are 16 IRQs
available but most of them are already in use by parts of the system which leaves
6 free for expansion cards.
Both ISA and PCI expansion cards may need to use IRQs. System IRQs are
available to cards installed in the ISA expansion but first, and any remaining IRQs
are then used by PCI cards. Currently, there are two types of ISA cards. The
original ISA expansion card design, now referred to as "Legacy" ISA cards,
requires that you configure the card`s jumpers manually and then install it in any
available slot on the ISA bus. You may use Microsoft's Diagnostic (MSD.EXE)
utility included in the Windows directory to see a map of your used and free IRQs.
For Windows 95 users, the "Control Panel" icon in "My Computer", contains a
"System" icon which gives you "Device Manager" tab. Double clicking on a
specific device give you "Resources" tab which shows the Interrupt number and
address. Make sure that no two 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 this 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
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 slot that has a card in it that requires an IRQ. 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.

2-5 External Connectors
1. Power connector (12-pin block): J2
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.

13. SMI suspend switch lead (SMI)
This allows the user to manually place the system into a suspend mode or
"Green" mode where system activity will be instantly decreased to save
electricity and expand the life of certain components when the system is not
in use. This 2-pin connector (see the figure below) connects to the case-
mounted suspend switch. If you do not have a switch for the connector, you
may use the "Turbo Switch" since it does not have a function. SMI is activated
when it detects a short to open moment and therefore leaving it shorted will
not cause any problems. May require one or two pushes depending on the
position of the switch. Wake-up can be controlled by settings in the BIOS but
the keyboard will always allow wake-up (the SMI lead cannot wake-up the
system). If you want to use this connector, "Suspend Switch" in the POWER
MANAGEMENT SETUP of the BIOS software should be on the default setting
of Enable (see page 26).

CMOS Battery and Ext Battery

Chapter 3
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.

To enter Setup Program
Power on the computer and press key immediately will bring you into BIOS
CMOS SETUP UTILITY.

Figure 3-1
The menu displays all the major selection items and allow user to select any one
of shown item. The selection is made by moving cursor (press any direction key)
to the item and press key. An on_line help message is displayed at the
bottom of the screen as cursor is moving to various items which provides user
better understanding of each function. When a selection is made, the menu of
selected item will appear so the user can modify associated configuration
parameters.


3-1 STANDARD CMOS SETUP

Choose "STANDARD CMOS SETUP" in the CMOS SETUP UTILITY Menu
(Figure 3-1). The STANDARD CMOS SETUP allows user to configure system
setting such as current date and time, type of hard disk drive installed in the
system, floppy drive type, and the type of display monitor. Memory size is
auto_detected by the BIOS and displayed for your reference. When a field is
highlighted (direction keys to move cursor and key to select), the entries
in the field will be changed by pressing or keys or user can enter
new data directly from the keyboard.

Figure 3-2

NOTE: If hard disk Primary Master/Slave and Secondary Master/Slave were used
Auto, than the hard disk size and model will be auto-detect on display during
POST.
NOTE: The "Halt On:" field is to determine when to halt the system by the BIOS is
error occurred during POST.




3-2 BIOS FEATURES SETUP
Select the "BIOS FEATURES SETUP" option in the CMOS SETUP UTILITY
menu allows user to change system related parameters in the displayed menu.
This menu shows all of the manufacturer's default values of 5VX32. Again, user
can move the cursor by pressing direction keys and of keys to
modify the parameters. Pressing [F1] key to display help message of the selected
item.

This setup program also provide 2 convinent ways to load the default parameter
data from BIOS [F6] or CMOS [F7] area if shown data is corrupted. This provides
the system a capability to recover from any possible error.

Note: The Security Option contians "setup" and "system". The "setup" indicates that
the password setting is for CMOS only while the "system" indicates the
password setting is for both CMOS and system boot up procedure.


Virus Warning: This category flashes on the screen. During and after the
system boots up, any attempt to write to the boot sector or partition table of
the hard disk drive will halt the system and the following error message will
appear, in the mean time, you can run an anti-virus program to locate the
problem. Default value is Disabled
Enabled: Activates automatically when the system boots up causing a
warning message to appear when anything attempts to access
the boot sector or hard disk partition table.
Disabled: No warning message to appear when anything attempts to
access the boot sector or hard disk partition table.

CPU Internal Cache / External Cache: These two categories speed up
memory access. However, it depends on CPU/chipset design. The default

Again, user can move the cursor by pressing direction keys to the field need to be
modified and press or to alter item selection. You can only
change the content of Doze Mode, Standby Mode, and Suspend Mode when the
Power Management is set to 'User Define'.


3-4-1 The Description of the Power Management

Power Management mode selection:
Disabled: The system operates in NORMAL conditions (Non-GREEN),
and the Power Management function is disabled.


26
Max.saving: This mode will maximize the power saving capability.
Min.saving: This mode will minimize the power saving capability.
User define: Allow user to define timeout parameters to control power
saving timing. Refer item B shown below.

Timeout parameters:
HDD Standby
HDD Standby timer can be set from 1 to 15 minute(s).

System Doze
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.

System Standby
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.

System Suspend
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.




3-4-2 Description of the Green Functions



27
The 5VX32 supports HDD Power Down, Doze and standby power saving
functions when Intel Pentium Processor CPU is installed. In addition, the suspend
function is supported when the SMI (sleep ref. Figure 2-1 be closed to enter the
green function). The detail description of these functions are provided in next
page.

HDD Standby Mode
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 hardware will drop down CPU clock from normal working speed when
Doze mode timeout occurred.
Standby Mode
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
When the system suspend timer time out, the system will enter the suspend mode
and the chipset will stop CPU clock immediately. The power consunption in
Suspend Mode is lower than in standby mode. The screen is also blanked out.
PM Events:
AWARD BIOS defines 15 PM Events in the power management mode (Doze,
standby & suspend). The user can initial any PM Events to be "Enable" or
"Disable". 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. By now, the system will not only process the standby power
saving procedures but also start the system suspend timer. When the suspend
timer time out, all of the CPU clock will be stopped by dropping system clock down
to zero and remains this way until any one of the "Enabled" event occurred.

3-5 PNP/PCI CONFIGURATION SETUP

This "PNP and PCI configuration Setup" option configures the PCI bus slots. All
PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to
this value.
