WARNING
Please realize that there is a certain risk involved with overclocking, including adjusting
the setting in the BIOS, applying Untied Overclocking Technology, or using the thirdparty overclocking tools. Overclocking may affect your system stability, or even
cause damage to the components and devices of your system. It should be done at
your own risk and expense. We are not responsible for possible damage caused by
overclocking.

CAUTION!
1. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
2. The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please check SiS
3. Power Management for USB 2.0 works fine under Microsoft
XP SP1 or SP2 / 2000 SP4.
4. Featuring an advanced proprietary hardware and software design,
Intelligent Energy Saver is a revolutionary technology that delivers
unparalleled power savings.
5. ASRock Instant Flash i s a BIOS flash utility embedded in Flash ROM.
This convenient BIOS update tool allows you to update system BIOS
without entering operating systems first like MS-DOS or Windows®. With
this utility, you can press <F6> key during the POST or press <F2> key to
BIOS setup menu to access ASRock Instant Flash. Just launch this tool
and save the new BIOS file to your USB flash drive, floppy disk or hard
drive, then you can update your BIOS only in a few clicks without preparing an additional floppy diskette or other complicated flash utility. Please
be noted that the USB flash drive or hard drive must use FAT32/16/12 file
system.
6. Although this motherboard offers stepless control, it is not recommended
to perform over clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU. The CPU host frequency of this motherboard is determined by the
jumper-setting. You must set the FSB jumper according to your AMD CPU
before you use the “Manual” option as the FSB setting in BIOS setup to
perform over clocking. Please check page 24 for details.
7. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.

8. EuP, stands for Energy Using Product, was a provision regulated by European
Union to define the power consumption for the completed system. According
to EuP, the total AC power of the completed system shall be under 1.00W in
off mode condition. To meet EuP standard, an EuP ready motherboard and an
EuP ready power supply are required. According to Intel’s suggestion, the EuP
ready power supply must meet the standard of 5v standby power efficiency
is higher than 50% under 100 mA current consumption. For EuP ready power
supply selection, we recommend you checking with the power supply manufacturer for more details.

motherboard. Before you install the motherboard, please study the configuration of your chassis to ensure that the motherboard fits into it.
Take note of the following precautions before you install motherboard components or change any motherboard settings.
1. Unplug the power cord from the wall socket bef ore 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 remember 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.

This motherboard adopts 462-pin CPU socket to support AMD Athlon
XP / Duron CPU. It requires larger heatsink and cooling fan to dissipate heat. You also need to spray thermal grease between the CPU
and the heatsink 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, No. 2). For proper installation, please
kindly refer to the instruction manuals of the CPU fan and the heatsink.

convenient BIOS update tool allows you to update system BIOS without
entering operating systems first like MS-DOS or Windows®. Just launch
this tool and save the new BIOS file to your USB flash drive, floppy disk or
hard drive, then you can update your BIOS only in a few clicks without
preparing an additional floppy diskette or other complicated flash utility.
Plea se be noted that the USB flash drive or hard drive must use FAT32/16/
12 file system. If you execute ASRock Instant Flash utility, the utility will
show the BIOS files and their respective information. Select the proper
BIOS file to update your BIOS, and reboot your system after BIOS update

[Manual]
This allows user to set CPU host frequency manually. However, because
the CPU host frequency of this motherboard is determined by the jumpersetting, you must set the FSB jumper adjustment according to your AMD
CPU before you use this “Manual” option as the FSB setting in BIOS setup
to perform over clocking. This is not recommended unless you thoroughly
know the feature. Wrong setup may cause problems during operation.
Actual Frequeny
This is a read-only item, which displays the actual frequency of this
motherboard.
Spread Spectrum
This field should always be [Disabled] for better system stability.
Boot Failure Guard
Enable or disable the feature of Boot Failure Guard.
Boot Failure Guard Count
Enable or disable the feature of Boot Failure Guard Count.
Over Vcore Voltage
This feature allows you to increase the CPU Vcore voltage by 3% or 6%.
The default value is [Disabled].
It is not recommended to enable “Over Vcore
