Chapter 1. Introduction of NV7m Features
1-1. Features of NV7m Motherboard
This motherboard is designed for AMD Socket A Athlon™XP, Athlon™and Duron™processors. It
supports the AMD Socket-A structure, with up to 1 GB (Unbuffered & Non-ECC) of memory, super I/O.
and Green PC functions. The ABIT NV7m is an excellent computer motherboard based on the innovative
nForce 420D chipset, which supports powerful Geforce 2 3D graphics, AC3 audio and LAN for an all in
one Micro ATX form factor solution with high performance value.
The NVIDIA nForce 420D chipset used in this motherboard supports two DDR DIMMs up to 1 GB
maximun. The memory controller can support Non-ECC DDR (up to DDR PC 2100 it running on 133
MHz) memory and support twin bank memory architecture for up to 4.2GB/s bandwidth. The AGP
interface can support external AGP slot with AGP 1X/2X/4X (1.5V graphics card only) capability and
Fast Write Transactions.
The NV7m has a built in Ultra DMA 100 function. This means that it provides speedier HDD throughput
boosting overall system performance. Ultra DMA 100 is the new standard for IDE devices. It enhances
existing Ultra DMA 33 technology by increasing both performance and data integrity. This new
high-speed interface almost doubles the Ultra DMA 66 burst data transfer rate to 100 Mbytes/sec. The
result is maximum disc performance using the current PCI local bus environment. Another benefit is you
can connect four IDE devices in your system through either Ultra DMA 66 or Ultra DMA 100. You will
have more flexibility to expand your computer system.
This motherboard also supports three PCI slots and one AGP slot. This motherboard has built-in hardware
monitoring functions that monitors and protects your computer, insuring a safe computing environment. It
equips the Realtek ALC201A 2-channel audio and 8201L 10/100 Mbps LAN controller.
The NV7m optional SPDIF out module turns your computer into a high-end entertainment system with
optical and coaxial connectivity to powerful speaker system (CA-21).

step all of the standard equipment and will also present, as completely as possible, future upgrade
capabilities. This motherboard is able to supports all AMD Socket A Athlon™XP, Athlon™and Duron™
processors now on the market. (For details, see specifications in Chapter 1.)
This chapter is organized according the following features:
2-1 Installation of the AMD Athlon™XP, Athlon™and Duron™CPU
2-2 Install The Motherboard
2-3 Install System Memory
2-4 Connectors, Headers and Switches
%%%% Before Proceeding with the Installation %%%%
Before you install or unplug any connectors or add-on cards, please remember to turn the ATX power
supply switch off (fully turn the +5V standby power off), or take the power cord off. Otherwise, you may
cause the motherboard components or add-on cards to malfunction or be damaged.

User Friendly Instructions
Please read our instructions carefully and follow them step-by-step. Our objective is to enable the novice
computer user to perform the installation by himself. We have attempted to write this document in a very
clear, concise and descriptive manner to help overcome any obstacles you may face during installation.
Diagram and Photos
This chapter contains many color drawings, diagrams and photos, we strongly recommend you read this
chapter use the PDF file that is stored on the CD-Title. Color improves the clarity and quality of the
diagrams. For the downloadable edition, as files larger than 3 MB are difficult to download, we will cut
the graphics and photo resolution to reduce the manual file size. In such this case, if your manual is
downloaded from our WEB site and not from a CD-ROM, enlarging graphics or photos will distort the
image.

2-1. Installation of the AMD Athlon™XP, Athlon™and Duron™
CPU
Note
!Installing a heatsink and cooling fan is necessary for heat to dissipate from your processor. Failing
to install these items may result in overheating and processor damage.
!The AMD Socket A processor will produce a lot of heat while operating, so you need to use a large
heat sink that is especially designed for the AMD socket A processor. Otherwise, it may result in
overheating and processor damage.
!If your processor fan and its power cable are not installed properly, never plug the ATX power
cable into the motherboard. This can prevent possible processor damage.
!Please refer to your processor installation manual or other documentation with your processor for
detailed installation instructions.
The AMD Socket A Athlon™XP, Athlon™and Duron™processor installation is easy, like Socket 7
Pentium®processors before. Because it uses the “Socket A” ZIF (Zero Insertion Force) socket, you can
easily fix the processor firmly into position. Figure 2-1 shows you what the socket A looks like, and how
to open the lever. The socket A has more pins than the socket 7. Therefore, a Pentium level processor
cannot be inserted into a socket A.
When you raise the lever, you have to loosen the socket lock. Please raise the lever to the end, and
prepare to insert the processor. Next, you need to align the processor pin 1 to the socket pin 1. If you put
it in the wrong direction, you will not be able to insert the processor easily, and processor pins will not
fully go into the socket. If this is the case, please change the direction, until it easily and fully inserts into
the socket A. See Figure 2-2 at the same time check the processor temperature detection thermistor height
(if your motherboard has this component), then you can slowly insert the processor into the Scoket A.
Finally, you need to check that the processor edge and the Socket A edge is parallel. It should be parallel
and not tilted.
When you finish the above, push the lever down to its original position, you should feel the lever lock the
socket A. You have then finished the processor installation.
