Introduction

Features and Specifications

Processor Upgrade

The system board is equipped with a 321-pin ZIF socket (Intel

Socket 7). This socket is designed for easy removal of an old

processor and easy insertion of an upgrade processor. The system

board is also equipped with a switching voltage regulator that

supports 2.1V to 3.5V core voltage for various processors.

•Intel Pentiumprocessor with MMXTM technology-166/200/

233MHz

•Intel Pentium90/100/120/133/150/166/200MHz

•Cyrix6x86L PR150+/PR166+/PR200+ and future 6x86MX

processors

•AMDK5 PR90/PR100/PR120/PR133/PR166

•AMDK6-166, K6-200, K6-233 and future K6 processors

Chipset

•Intel82430TX PCIset chipset

System Memory

The system board supports 8MB to 256MB of memory. It is

equipped with two DIMM and four SIMM sockets. The 168-pin

DIMM sockets use x64 EDO (60/70ns), fast page mode (60/70ns),

or SDRAM (10/12/13ns), 3.3V. The 72-pin SIMM sockets use EDO

or fast page mode, 60/70ns, x32 DRAM, 5V.

Cache Memory

•512KB pipeline burst, direct map write-back cache installed on

the system board.

BIOS

•Award BIOS, Windows95 Plug and Play compatible

•Flash EPROM for easy BIOS upgrades

•Supports DMI function

586ITXD System Board User’s Manual

Energy Efficient Design

•System power management supported

•CPU stopped clock control

•Hardware supports SMI green mode

•Microsoft®/Intel®APM 1.2 compliant

•Soft Power supported - ACPI v1.0a specification

ACPI Specification and OS Directed Power

Management

The system board is designed to meet the ACPI (Advanced

Configuration Power Interface) specification. It has energy saving fea-

tures which enable operating systems to reliably manage and coor-

dinate power planes, PnP (Plug-and-Play) peripherals, and cooling

fans. The system board is PC 97 compliant. Microsoft's PC 97

"OnNow" design allows continual "power on" with reduced energy

consumption.

RTC Timer to Power On the System

The RTC installed on the system board allows your system to

automatically wake up on the set date and time. Set the date and

time you would like your system to power on in the “Resume By

Alarm” field of the Power Management Setup (Chapter 2).

Modem Wake-up/Ring-on

The Modem Wake-Up feature allows the sleeping (Suspend mode)

PC to wake-up to respond to incoming calls. The Modem Ring-on

feature allows the Soft Power Down (Soft-Off) PC to power on to

respond to incoming calls. Enable this function in the “Resume By

Ring” field of the Power Management Setup (Chapter 2). Make sure

to select an IRQ channel for the external modem in the “Modem

Use IRQ” field of the Power Management Setup and set JP11 to

the COM port where the modem is connected (Chapter 3).

Note:

This feature supports external modem only.

Introduction

Suspend to Disk

The system board supports the Suspend to Disk function. With

the ZVHDD utility installed, the system is capable of storing all

information of the current operating session into the hard drive

before the system powers off. The saved data includes all the

programs and data files loaded into system memory during the

session. The operating session will resume exactly where you left off

the next time you power on the system. Refer to the “Suspend

Mode Option” field of the Power Management Setup (Chapter 2)

and the ZVHDD utility (Appendix E) for instructions on using this

function.

Damage Free Intelligence

•CPU Slow Down

The system board is capable of monitoring the temperature of

the processor. If the processor's fan fails to function or the

temperature of the processor exceeds 85oC, the system will

decrease CPU utilization by slowing down the CPU clock.. This

will prevent the processor from being damaged.

•Monitors processor temperature and overheat alarm

The system board is able to detect the temperature of the

processor. An alarm will sound in case of processor overheat.

Refer to Chipset Features Setup (Chapter 2).

•Monitors processor fan speed and failure alarm

The system board is able to detect the processor’s fan speed

(RPM - Revolutions Per Minute) and alerts you to attend to

any irregularity that may damage your system. Refer to Chipset

Features Setup (Chapter 2).

•Monitors power voltages and failure alarm

The system board is able to detect the chipset’s voltage and

output voltage of the power supply. An alarm will sound warning

you of voltage irregularity. Refer to Chipset Features Setup

(Chapter 2).

•Automatic fan control

With the system’s power switched on, the processor’s fan will

rotate only if the temperature of the processor is over 32oC. This

586ITXD System Board User’s Manual

saves energy, prevents system overheat, prolongs fan life and

implements a silent system. Refer to the “CPU Fan Connector”

section (Appendix B) for more information.

Dual Function Power Button

Dual Function Power Button allows two distinct OFF modes. If you

accidentally pushed the power button, it enters the Suspend mode

and if released in less than 4 sec., the system returns to normal. The

purpose of this function is to prevent the system from powering off

in case you accidentally “hit” or pushed the power button. “Soft-Off

By PWR-BTTN” in the Power Management Setup (Chapter 2) allows

you to select the method of powering off your system.

HDD Interface

•Two PCI IDE interfaces support up to four IDE devices

•Ultra DMA/33 supported (Synchronous DMA mode - data

transfer rate up to a maximum of 33MB/sec.)

•PIO Mode 3 and Mode 4 Enhanced IDE (data transfer rate up

to 16.6MB/sec.)

•Bus mastering reduces CPU utilization during disk transfer

•ATAPI CD-ROM supported

•LS-120 and ZIP supported

FDD Interface

•One floppy drive interface supports up to 2.88MB floppy drives

Onboard I/O

•Two NS16C550A-compatible serial ports

•One SPP/ECP/EPP parallel port

•One PS/2 mouse port

•One PS/2 keyboard port

USB Ports

The system board is equipped with two USB ports. USB allows

data exchange between your computer and a wide range of

simultaneously accessible external Plug and Play peripherals.
