Caution

Be sure to unplug the AC power supply before adding or
removing expansion cards, RAM or other system peripherals,
otherwise your mainboard and RAM might be seriously damaged.

Caution

Be sure to add some Silicone Grease between the CPU and the
heatsink to keep them fully contacted to meet the heat sink require­ment.

Chapter 1

P5I848P series of mainboards utilize Intel® 848P + ICH5
chipset, providing a fully compatible, high performance and
cost-effective ATX platform. The new integrated
tec hnologies, together with AC’97 audio(2/6-channel), 8
USB, 2 SATA, and ATA100/66/33, give customers an
advanced, multimedia solution at reasonable price. It pro­vides 533/800MHz host bu s speed to support Intel® LGA775
processors and the DDR266/333/400 memory. It also pro­vides advanc ed features such as ACPI function. Suspend­ing to RAM, the optimal implementation of the Advanced
Configuration and Power Interfac e (ACPI) specification,
makes the PC’s power consumption drop to the lowest pos­sible level and enable quick wakeup.

Jumpers are located on the mainboard, the clear CMOS jumper CLR_CMOS, enable
keyboard password power-on function jumper JKB etc. Pin 1 for all jumpers are located

on the side with a thick white line (Pin1→ ), referring to the mainboard’s
silkscreen. Jumpers with thre e pins will be shown as to represent pin1 & pin2
(“1-2”) closed and to represent pin2 & pin3 (“2-3”) closed.

BIOS-Protection Jumper (BIOS_WP)

The BIOS of the mainboard is inside the FWH. If the jumper BIOS_WP is set as

closed, the system BIOS is protected from being attacked by serious virus suc h as
CIH virus, you will be unable to flash the BIOS to the mainboard in this status.

BIOS_WP

The DMI (Desktop Management Interface) system information such as the CPU type/

speed, memory s ize, and expansion cards will be detected by the onboard BIOS and
stored in the flash ROM. Whenever the system hardware config uration is changed, DMI
information will be updated automatically. However, setting jumper BIOS_WP as closed
makes flashing BIOS and updating DMI information impo ssible. Therefore, set BIOS_WP
as open when changing the system hardware config uration, or the error message “Un­known Flash Type” will be displayed on the sc reen, and DMI information may not be
updated.

Furthermore in order to implement this func tion, set “POWER ON Function” to “Pass­word” and enter the keyboard power-on password in the “INTEGRATED PERIPHER­ALS” section of the CMOS SETUP. Save and exit, then power off your system. In this
case, the power button’s power-on function is disabled.

A Note:

1. If using this function, 5VSB line of the power supply should be
capable of delivering enough current for all the devices con
nected to the keyboard port, if not, you will be unable to power
up the sys tem using the keyboard.

2. If you set JKB with pin2 & pin3 closed, set “POWER ON Func
tion” to BUTTON ONLY, don’t set it to Password, or you’ll be
unable to power up your system by the keyboard or the power
button.

3. If you encounter the above problems, clear CMOS and set
the jumper pin2 and pin3 closed to disable the function,them
power on the system by pushing the power button,and set
“power on Fuction” back to “Button Only”.

AWDFLASH.EXE

This is a flash memory write/read utility used for the purpose of upgrading your BIOS
when necessary. Before doing so, please note:

We strongly recommend you only upgrade BIOS when encounter problems.
Before upgrading your BIOS, review the description below to avoid making

mistakes, destroying the BIOS and resulting in a non-working system.

When you encounter problems, for example, you find your system does not support
the latest CPU released after our current mainboard, you may therefore upgrade the
BIOS, please don’t forget to set BIOS_WP as open and disable the “Flash Write Pro­tect” ite m in AWARD BIOS CMOS Setup first .

Follow the steps exactly for a successful upgrade.

1. Create a bootable system floppy diskette by typing Format A:/s from the DOS
prompt under DOS6.xx or Windows 9x environment.

2. Copy AWDFLASH.EXE(version>=8.24) from the directory \Utility located on QDI

Driver CD to your new bootable disk ette.

3. Download the updated BIOS file from the Website (http://www.qdigrp.com). Please
be sure to download the suitable BIOS file for your motherboard.

4. Decompress the file download, copy the BIOS file (xx.bin) to the bootable diskette,
and note the checksum of this BIOS which is located in readme file.

5. Reboot the system from the bootable diskette created.

6. Then run the AWDFLASH utility at the A:\ prompt as shown below:

A:\AWDFLASH xxxx.bin
Follow the instruc tion through the process. Don’t turn off power or reset the system

until the BIOS upgrade has been completed.

If you require more detailed information concerning AWDFLASH Utility, for example,

the different usage of parameters, pleas e type A:\>AWDFLASH /?

The integrated peripherals setup allows user to configure the onboard IDE controller,
floppy disk controller, the printer port and the serial ports etc..

PC Health Status

The PC health status display CPU and cas e fan speed.

Set Supervisor/User Password

Changes, sets, or disables password. It allows you to limit access to the system and
the setup program.When this function is selected, the following message appears at
the center of the screen to assist you in creating a password.

ENTER PASSWORD

Type the password, up to eight characters, and press <Enter>. The password typed
now will clear any previously en tered password from CMOS memory. You will be asked
to confirm the password. Type the password again and press <Enter>. You may also
press <Esc> to abort the selection.
To disable password, just press <Enter> when you are prompted to enter password. A
message will confirm the password being disabled. On ce the password is disabled, the
system will boot and you can enter BIOS Setup freely.

PASSWORD DISABLED

If you have selected “System” in “Security Option” of “BIOS Features Setup” menu,
you will be prompted for the password every time the system reboots or any time you
try to enter BIOS Setup.
If yo u have selected “Setup” at “Security Option” from “BIOS Features Setup” menu, you
will be prompted for the password only whe n you enter BIOS Setup.
Supervisor Password has higher priority than User Password. You can use Supervisor
Password when booting the system or entering BIOS Setup to modify all settings.
Also you can use Use r Password when booting the system or entering BIOS Setup but
can not modify any setting if Supervisor Password is enabled.

Load Optimized Defaults

The Optimized Defaults are common and efficient. It is recommended users load the
optimized defaults first, then modify the needed configuration settings.

Save & Exit Setup

Saves value changes to CMOS and exits setup.

Exit Without Saving

Abandons all CMOS value changes and exits setup.

Note: if you need detailed information about BIOS, please view them in the CD.

SpeedEasyII

SpeedEasy II — has just recommended is the upgraded edition of SpeedEasy In addi­tion to some functions of SpeedEasy, including the wire jumper-free function, the
users can also realize in the BIOS setup the CPU core voltage adjustability. This
doubtless renders a quicker and ea sier mode for overclocking and will further help the
users to tap the maximum potentiality of the system.

BootEasy

BootEasy techno logy enormously improves the long BOOT process time of computers.
Reducing the wait time every user has to suffer when starting their computer. BIOS
without BootEasy has to perform many routines every time when the system starts,
such as checking system core of the computer and initializing system peripherals.
Now with the BootEasy, BIOS will not run these repetitive Processes any longer , PC
can boot-up without any redundant waiting for the displaying of starting OS. BootEasy
save all the information when PC first normally boot-up, and it restores all the param­eters for the system and thus let the PC boot freely and rapidly.
