Chapter 2 Installation
P4i45GL/P4i45GV is a Micro ATX form factor (9.6-in x 8.2-in, 24.4 cm x 20.8 cm)
motherboard. Before you install the motherboard, study the configuration of your
chassis to ensure that the motherboard fits into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard compo-
nents or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also re-
member to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that comes with the component.
Before you install or remove any component, ensure that the
power is switched off or the power cord is detached from the
power supply. Failure to do so may cause severe damage to
the motherboard, peripherals, and/or components.

14
2.1 CPU Installation
Step 1. Unlock the socket by lifting the lever up to a 90oangle.
Step 2. Position the CPU directly above the socket such that its marked corner
matches the base of the socket lever.
Step 3. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the
CPU into the socket to avoid bending of the pins.
Step 4. When the CPU is in place, press it firmly on the socket while you push
down the socket lever to secure the CPU. The lever clicks on the side tab
to indicate that it is locked.
2.2 Installation of CPU Fan and Heatsink
Intel®Pentium®4 CPU requires larger heatsink and cooling fan. Thermal
grease between the CPU and the heatsink is also needed to improve heat
dissipation. Make sure that the CPU and the heatsink are securely fastened
and in good contact with each other. Then connect the CPU fan to the
CPU_FAN connector (CPU_FAN1, see page 10/11, No. 5). For proper
installation, please kindly refer to the instruction manuals of the CPU fan
and heatsink vendors.
STEP 1:
Lift Up The Socket Lever
STEP 2/STEP 3:

2.3 Installation of Memory Modules (DIMM)
P4i45GL/P4i45GV motherboard provides two 184-pin DDR (Double Data Rate) DIMM
slots.
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause
permanent damage to the motherboard and the DIMM if you
force the DIMM into the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends fully
snap back in place and the DIMM is properly seated.

2.4 Expansion Slots (PCI, AMR, and AGI Slots)
There are 3 PCI slots, 1 AMR slot, and 1 AGI slot on this motherboard.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
Because the installed AMR card will occupy the same external
connecting position with the PCI card installed in “PCI3” slot, you will
no be able to install any PCI card in “PCI3” slot if an AMR card has
already been installed in the AMR slot.
AMR slot: AMR slot is used to insert an ASRock MR card (optional) with v.92
Modem functionality.
AGI slot: The AGI [ASRock Graphics Interface] slot is a special design that only
supports compatible AGP VGA cards. For the information of the compat-
ible AGP VGA cards, please refer to the “Supported AGP VGA Cards List”
on page 8.
To install the system with an add-on AGP VGA card, you must make
sure to install the driver of add-on AGP VGA card before you install
the onboard VGA driver. If the onboard VGA driver has already been
installed before you install the add-on AGP VGA card, the system will
automatically set the onboard VGA as the primary graphics adapter. In
that case, if you want to install the add-on AGP VGA card, you need
to remove the onboard VGA driver first, and then install the add-on
AGP VGA card and its driver. For the detailed instruction, please refer
to the documents in the Support CD, “AGI Slot Installation Guide (for
Windows 2000)” and “AGI Slot Installation Guide (for Windows XP)”,
which are located in the folder at the following path:
..\ Easy Dual Monitor
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed in a
chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the screws
for later use.
Step 4. Align the card connector with the slot and press firmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

17
2.5 Easy Dual Monitor Feature
Thanks to ASRock patented AGI8X Technology, this motherboard supports
Easy Dual Monitor upgrade. With the internal onboard VGA and the external
add-on AGP VGA card, you can easily enjoy the benefits of Dual Monitor
feature. For the detailed instruction, please refer to the document at the
following path in the Support CD: ..\ Easy Dual Monitor
2.6 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “SHORT”. If no jumper cap
is placed on pins, the jumper is “OPEN”. The
illustration shows a 3-pin jumper whose pin1
and pin2 are “SHORT” when jumper cap is
placed on these 2 pins.
Jumper Setting Description
PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.10/p.11, No. 1) +5VSB (standby) for PS/2 or

Chapter 3 BIOS Setup
3.1 BIOS Setup Utility
This section explains how to configure your system using the BIOS Setup Utility. The
BIOS FWH chip on the motherboard stores the BIOS Setup Utility. When you start up
the computer, there is a chance for you to run the BIOS Setup. Press <F2> during the
Power-On-Self-Test (POST) to enter the BIOS Setup Utility, otherwise, POST
continues with its test routines.
If you wish to enter the BIOS Setup after POST, restart the system by pressing
<Ctl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis. You
can also restart by turning the system off and then back on.
The BIOS Setup Utility is designed to be user-friendly. It is a menu-driven program,
which allows you to scroll through its various sub-menus and select among the
predetermined choices.
Because the BIOS software is constantly being updated, the
following BIOS setup screens and descriptions are for reference
purpose only, and may not exactly match what you see on your
screen.
3.1.1 BIOS Menu Bar
The top of the screen has a menu bar with the following selections:
MAIN Sets up the basic system configuration
ADVANCED Sets up the advanced features
SECURITY Sets up the security features
POWER Configures Power Management features
BOOT Configures the default system device that is used
to locate and load the Operating System
EXIT Exits the current menu or the BIOS Setup
To access the menu bar items, press the right or left arrow key on the keyboard
until the desired item is highlighted.
3.1.2 Legend Bar
At the bottom of the Setup Screen is a legend bar. The following table lists the keys
in the legend bar with their corresponding functions.
