Introducing the Mainboar d
IInnttrroodduuccttiioonn
Thank you choosing the K7SOM+ mainboard. This mainboard has a Socket462 processor socket for the AMD K7 type of processors. You can install any
of these processors on this mainboard. This mainboard supports front-side
bus speed of 266MHz.
This mainboard integrates the SiS740 Northbridge and SiS962/962L
Southbridge chipsets that support a DDR/SDRAM interface, Ultra DMA
33/66/100/133 function and remarkably high system performance under all
types of system operations.
This mainboard has a built-in AC97 Codec, providing an AMR (Audio Modem
Riser) slot to support Audio and Modem application, and a built-in
10BaseT/100BaseTX Network Interface. This mainboard has the embedded
256-bit 3D AGP Graphics Accelerator with 64MB frame buffer, supporting AGP
4X 266MHz mode up to 2GB/s bandwidth, which provides a direct connection
between the graphics sub-system and memory so that the graphics do not
have to compete for processor time with other devices on the PCI bus. The
mainboard supports built-in USB 2.0 providing higher bandwidth, implements
Universal Serial Bus Specification Revision 2.0 and is compliant with UHCI 1.1
and EHCI 0.95. This mainboard also supports the optional built-in IEEE1394a
function only when SiS962 SB is installed.
There is a set of ATX I/O Ports including two PS/2 ports for keyboard and
mouse, one parallel port, one serial port and one VGA port, one MIDI/Game
port and maximum four USB 2.0 ports—two back-panel ports and onboard
USB header making two extra USB ports by connecting the Extended USB
Module to the mainboard.
The board is Micro ATX size and has power connectors for an ATX power
supply.

There are many types of computer cases on the market. The mainboard complies with the specifications for the micro-ATX system case. Some features on
the mainboard are implemented by cabling connectors on the mainboard to
indicators and switches on the system case. Ensure that your case supports
all the features required. The mainboard can support one floppy diskette drive
and four enhanced IDE drives. Ensure that your case has sufficient power and
space for all the drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the mainboard.
This mainboard has a micro-ATX form factor of 24.5 x 24.5 cm. Choose a
case that accommodates this form factor.
This concludes Chapter 1. The next chapter explains how to install the mainboard.

Follow these safety precautions when installing the mainboard:
• W ear a grounding strap attached to a grounded device to avoid
damage from static electricity.
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the mainboard.
• Leave components in the static-proof bags they came in.
• Hold all circuit boards by the edges. Do not bend circuit boards.

Refer to the following illustration and instructions for installing the mainboard
in a case:
This illustration shows an example of a mainboard being
installed in a tower-type case:
Note: Do not overtighten
the screws as this
can stress the mainboard.
Most system cases have
mounting brackets i nstalled in
the case, which correspond to
the holes in the mainboard.
Place the mainboard over the
mounting brackets and secure
the mainboard onto the mount ing brackets with screws.
2. Secure the mainboard with
screws where approp ria t e .
1. Place the mainboard
over the mounting brackets.
Ensure that your case has an I/O template that supports the I/O ports and
expansion slots on your mainboard.

This section explains how to set jumpers for correct configuration of the mainboard.
Setting Jumpers
Use the mainboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the
jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPE N.
Short Open
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

Checking Jumper Settings
The following illustration shows the location of the mainboard jumpers. Pin 1 is
labeled.
Jumper Settings
Jumper Type Description Setting (default)
JP1 3-pin Clear CMOS
jumper
J30 4-pin LAN LED Indica-
tor
JP1: Clear CMOS Jumper
Use this jumper to clear the contents of the CMOS memory. You may need to
clear the CMOS memory if the settings in the Setup Utility are incorrect and
prevent your mainboard from operating. To clear the CMOS memory, disconnect all the power cables from the mainboard and then move the jumper cap
into the CLEAR setting for a few seconds.
J30: LAN LED Indicator
This jumper connected with a LAN device needs a LED indicator.
Note: The plus sign (+) indicates a pin must be connected to a positive voltage.
