Introducing the Mainboard

Thank you choosing the K7SOM+ mainboard. This mainboard has a Socket-A

support for the AMD K7 processors. The Socket-A processor’s front-side bus

speed is 266MHz.

This mainboard integrates the SiS740 Northbridge and SiS962L Southbridge

chipsets that support DDR 266MHz, Ultra DMA 33/66/100/133 function and

remarkably high system performance under all types of system operations.

The mainboard supports the built-in AC97 Codec, two 32-bit PCI slots, one

CNR (Communications and Networking Riser) slot, and a built-in

10BaseT/100BaseTX Network Interface (optional).

This mainboard has the embedded 256-bit 3D AGP Graphics Accelerator with

64MB frame buffer, supporting AGP 4X 266MHz mode up to 1GB/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 pro-

viding higher bandwidth implements Universal Serial Bus Specification

Revision 2.0 and is compliant with UHCI 1.1 and EHCI 0.95.

There is a full set of I/O ports including two PS/2 ports for mouse and key-

board, one serial port, one parallel port, one VGA port and maximum six

USB2.0 ports– four back-panel ports and onboard USB header USB2 provid-

ing two extra 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.

BIOS Firmware This mainboard uses AMI BIOS that enables users to config-

ure many system features including the following:

• Hard drives, diskette drives, and peripherals

• Power management

• CPU parameters and memory timing

• Hardware monitoring parameters

The firmware can also be used to set parameters for different

processor clock speeds.

Some hardware specifications and software items are subject to change

without prior notice.

There are many types of computer cases on the market. The mainboard com-

plies 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 24.4 x 19 cm. Choose a case

that accommodates this form factor.

This concludes Chapter 1. The next chapter explains how to install the main-

board.
