Introduction

This page contains a summary of the important notes that must be

given special attention to prior to using the system board.

Processor

 The frequency ratio of some processors may have been locked

by the manufacturer. If you are using this kind of processor,

setting an extended ratio for the processor will have no effect.

The system will instead use its factory default ratio.

 The frequency ratio of processors greater than 8x has been

locked by the manufacturer and will no longer have the flexibility

of using extended ratios. Therefore, the system will use the

processors factory default ratio.

 Selecting an external bus clock other than 66MHz, 100MHz or

133MHz may result to the processors or systems instability and

are not guaranteed to provide better system performance.

System Memory

The system board supports both VCM and PC SDRAM DIMMs. If

you are using more than one DIMM, make sure you insert the same

type of DIMMs into the DIMM sockets. Using different types (VCM

or PC SDRAM) of DIMMs may cause problems.

5VSB Power

 If you are using the (1) Wake-On-LAN and/or (2) Wake-On-

Ring (internal modem) functions, the 5VSB power source of your

power supply must support ≥720mA.

 If you are using the Suspend to RAM function, the 5VSB power

source of your power supply must support ≥1A.

Drivers

Make sure to reboot the system after each driver installation.

Problems will occur if you reboot only after installing all the drivers.

Note:

If you are using more than one DIMM, make sure you insert

the same type of DIMMs into the DIMM sockets. Using

different types (VCM or PC SDRAM) of DIMMs may cause

problems.

Introduction

Expansion Slots

The CM35-SC system board is equipped with 1 shared AGP / DFP

(Digital Flat Panel) slot while CM30-SC is only equipped with the

DFP slot.

The AGP slot on the CM35-SC system board is a universal AGP

slot. AGP is an interface designed to support high performance 3D

graphics cards. It utilizes a dedicated pipeline to access system

memory for texturing, z-buffering and alpha blending. The universal

AGP slot supports AGP 2x with up to 533MB/sec. bandwidth and

AGP 4x with up to 1066MB/sec. bandwidth for 3D graphics

applications. AGP in this system board will deliver faster and better

graphics to your PC.

Both system boards are also equipped with 2 dedicated PCI slots

and 1 shared AMR/ISA slot. AMR (Audio/Modem Riser) is an

interface designed for installing an audio riser card, modem riser card

or audio/modem riser card that is compliant to the AMR

specification.

Introduction

IrDA Interface

The system board is equipped with an IrDA connector for wireless

connectivity between your computer and peripheral devices. It

supports peripheral devices that meet the HPSIR and ASKIR

standard.

USB Ports

The system board supports 4 USB ports. Two onboard USB ports

are located at the ATX double deck ports of the board. The J23

connector on the system board allows you to connect the optional

3rd and 4th USB ports. These optional USB ports, which are

mounted on a card-edge bracket, will be provided as an option.

USB allows data exchange between your computer and a wide

range of simultaneously accessible external Plug and Play peripherals.

Desktop Management Interface (DMI)

The system board comes with a DMI 2.0 built into the BIOS. The

DMI utility in the BIOS automatically records various information

about your system configuration and stores these information in the

DMI pool, which is a part of the system board's Plug and Play

BIOS. DMI, along with the appropriately networked software, is

designed to make inventory, maintenance and troubleshooting of

computer systems easier. Refer to chapter 4 for instructions on using

the DMI utility.
