CAUTION!
1. While CPU overheat is detected, the system will automatically shutdown.
Please check if the CPU fan on the motherboard functions properly before
you resume the system. To improve heat dissipation, remember to spray
thermal grease between the CPU and the heatsink when you install the PC
system.
2. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
3. Power Management for USB 2.0 works fine under Microsoft®Windows®
XP SP1/2000 SP4. It may not work properly under Microsoft®Windows®
98/ME. Please refer to Microsoft®official document at
http://www.microsoft.com/whdc/hwdev/bus/USB/USB2support.mspx
4. 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.

Chapter 2 Installation
K7S41 / K7S41GX is a Micro ATX form factor (9.6-in x 7.8-in, 24.4 cm x 19.8 cm)
motherboard. Before you install the motherboard, please study the configura-
tion 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.
