1.2 Motherboard Layout

Hardware Setup
A-S78H 1-3
1.3 Choosing a Computer Chassis
• Choose a chassis big enough to install this motherboard.
• As some features for this motherboard are implemented by cabling connectors on the
motherboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.
• If there is a possibility of adopting some more hard drives, make sure your chassis has
sufficient power and space for them.
• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O
shield of the chassis matches the I/O port configuration of this motherboard. You can find
an I/O shield specifically designed for this motherboard in its package.
1.4 Installing Motherboard
Most computer chassis have a base with many
mounting holes to allow the motherboard to be
securely attached, and at the same time, prevent
the system from short circuits. There are two
ways to attach the motherboard to the chassis
base: (1) with studs, or (2) with spacers.
Basically, the best way to attach the board is
with studs. Only if you are unable to do this
should you attach the board with spacers. Line up the holes on the board with the mounting
holes on the chassis. If the holes line up and there are screw holes, you can attach the board
with studs. If the holes line up and there are only slots, you can only attach with spacers. Take
the tip of the spacers and insert them into the slots. After doing this to all the slots, you can
slide the board into position aligned with slots. After the board has been positioned, check to
make sure everything is OK before putting the chassis back on.
※ Always power off the computer and unplug the AC power cord before adding or
removing any peripheral or component. Failing to so may cause severe damage
to your motherboard and/or peripherals. Plug in the AC power cord only after
you have carefully checked everything.
To install this motherboard:
1. Locate all the screw holes on the
motherboard and the chassis base.
2. Place all the studs or spacers needed on
the chassis base and have them tightened.
3. Face the motherboard’s I/O ports toward
the chassis’s rear panel.
4. Line up all the motherboard’s screw holes
with those studs or spacers on the chassis.
5. Install the motherboard with screws and
have them tightened.
※ To prevent shorting the PCB circuit,
please REMOVE the metal studs or
spacers if they are already fastened
on the chassis base and are without
mounting-holes on the motherboard
to align with.
Face the chassis’s rear panel.

1-4 A-S78H
1.5 Checking Jumper Settings
• For a 2-pin jumper, plug the
jumper cap on both pins will
make it CLOSE (SHORT).
Remove the jumper cap, or
plug it on either pin
(reserved for future use) will
leave it at OPEN position.
SHORT OPEN OPEN
• For 3-pin jumper, pin 1~2 or pin 2~3 can be
shorted by plugging the jumper cap in.
Pin 1~2 SHORT Pin 2~3 SHORT
1.5.1 CMOS Memory Clearing Header and Backup Battery
The time to clear the CMOS memory occurs when (a)
the CMOS data becomes corrupted, (b) you forgot the
supervisor or user password preset in the BIOS menu,
(c) you are unable to boot-up the system because the
CPU ratio/clock was incorrectly set in the BIOS menu,
or (d) whenever there is modification on the CPU or
memory modules.
This header uses a jumper cap to clear the CMOS
memory and have it reconfigured to the default values
stored in BIOS.
• Pins 1 and 2 shorted
(Default): Normal
operation.
• Pins 2 and 3 shorted:
Clear CMOS memory.
To clear the CMOS memory and load in the default values:
1. Power off the system.
2. Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper
cap back to its default settings --- pin 1 and pin 2 shorted.
3. Power on the system.
4. For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS
setup menu right after powering on system.
5. Set the CPU operating speed back to its default or an appropriate value.
6. Save and exit the BIOS setup menu.

Hardware Setup
A-S78H 1-5
CMOS Backup Battery:
An onboard battery saves the CMOS memory to keep the BIOS information stays on even after
disconnected your system with power source. Nevertheless, this backup battery exhausts after
some five years. Once the error message like “CMOS BATTERY HAS FAILED” or “CMOS
checksum error” displays on monitor, this backup battery is no longer functional and has to
be renewed.
To renew the backup battery:
1. Power off the system and disconnect with AC power source.
2. Remove the exhausted battery.
3. Insert a new CR2032 or equivalent battery. Pay attention to its polarity. The “+” side is its
positive polarity.
4. Connect AC power source and power on the system.
5. Enter the BIOS setup menu. Reconfigure the setup parameters if necessary.
CAUTION:
※ Danger of explosion may arise if the battery is incorrectly renewed.
※ Renew only with the same or equivalent type recommended by the battery
manufacturer.
※ Dispose of used batteries according to the battery manufacturer’s instructions.

1.7.2 DDR2 Memory Slots
To reach the performance of Dual Channel DDR2, the following rules must be obeyed:
• For a 2-DIMM dual-channel installation:
Populate DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], or slots
[DIMM3]+[DIMM4].
• For a 4-DIMM dual-channel installation:
Populate 2 DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], and
another 2 DIMM modules of the same type and size on slots [DIMM3]+[DIMM4].
※ [DIMM1] and [DIMM2] slots are made of the same color.
[DIMM3] and [DIMM4] are made of another same color.
Usually there is no hardware or BIOS setup requires after adding or removing memory modules,
but you will have to clear the CMOS memory first if any memory module related problem
occurs.
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only fits in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
※ Static electricity can damage the electronic components of the computer or
optional boards. Before starting these procedures, ensure that you are
discharged of static electricity by touching a grounded metal object briefly.
