Hub (GMCH)

The GMCH/MCH supports high-performance integrated graphics and manage the

data ﬂ ow of the following ﬁ ve interfaces: the CPU interface, DDR2 interface, PCI

Express Graphic Interface, the DMI (Direct Media Interface) and integrated graphics

with display interfaces (*GMCH only) . The GMCH/MCH supports a FSB frequency

of 533/800/1066 MHz using a scalable CPU. It supports up to two channels of

non-ECC DDR2 400/533/667 SDRAM. The integrated Graphics Controller provides

3D, 2D and display capabilities. The GMCH/MCH also supports advanced desktop

power management.

PDSLA/PDSLE User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the PDSLA/PDSLE.

The motherboard has an onboard System Hardware Monitor chip that supports

PC health monitoring.

Onboard Voltage Monitors for the CPU Core, Chipset Core +1.5V,

+3.3V, +3.3V standby, +5V, +5V Standby, Vbat and ±12V

The onboard voltage monitor will scan these voltages continuously. Once a voltage

becomes unstable, it will give a warning or send an error message to the screen.

Users can adjust the voltage thresholds to deﬁ ne the sensitivity of the voltage

monitor by using SD III.

Fan Status Monitor with Software

The PC health monitor can check the RPM status of the cooling fans via Supero

Doctor III.

Fan Fail Alert

When a fan fails during the normal operation, the Fan Fail LED will start to blink

and the buzzer will be activated to indicate a fan failure.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning function

in the BIOS. This allows the user to deﬁ ne an overheat temperature. When this

temperature reaches the pre-deﬁ ned threshold, the CPU thermal trip feature will be

activated and it will send a signal to the Speaker LED and, at the same time, the

CPU speed will be decreased.

Chapter 1: Introduction

1-11

1-4 Power Conﬁ guration Settings

This section describes features of your motherboard that deal with power and

power settings.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake-up and the LED will automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, it keyboard will function

like a normal keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button. When the user presses the power button, the system will enter

a SoftOff state. The monitor will be suspended and the hard drive will spin down.

Pressing the power button again will cause the whole system to wake-up. During

the SoftOff state, the ATX power supply provides power to keep the required circuitry

in the system alive. In case the system malfunctions and you want to turn off the

power, just press and hold the power button for 4 seconds. The power will turn off

and no power will be provided to the motherboard.

Wake-On-Ring (WOR) Header

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the SoftOff state. Note that external modem ring-on can only

be used with an ATX 2.01 (or above) compliant power supply.

1-12

PDSLA/PDSLE User’s Manual

1-5 Power Supply

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates of 1 GHz and faster.

The

PDSLA/PDSLE accommodates 12V ATX power supplies. Although

most power supplies generally meet the speciﬁ cations required by the CPU, some

are inadequate. A 2-Amp of current supply on a 5V Standby rail is strongly recom-

mended.

It is strongly recommended that you use a high quality power supply that meets

12V ATX power supply Speciﬁ cation 1.1 or above. It is also required that the 12V

4-pin power connection (J41) be used for high-load conﬁ gurations. In areas where

noisy power transmission is present, you may choose to install a line ﬁ lter to shield

the computer from noise. It is recommended that you also install a power surge

protector to help avoid problems caused by power surges.

Chapter 1: Introduction

1-13

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a ﬂ oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, drive interface control logic and interrupt and DMA logic. The wide range of

functions integrated onto the Super I/O greatly reduces the number of components

required for interfacing with ﬂ oppy disk drives. The Super I/O supports two 360

K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,

500 Kb/s or 1 Mb/s.

It also provides two high-speed, 16550 compatible serial communication ports

(UARTs), one of which supports serial infrared communication. Each UART in-

cludes a 16-byte send/receive FIFO, a programmable baud rate generator, complete

modem control capability and a processor interrupt system. Both UARTs provide

legacy speed with baud rate of up to 115.2 Kbps as well as an advanced speed

with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Conﬁ guration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be ﬂ exibly adjusted

to meet ISA PnP requirements, which support ACPI and APM (Advanced Power

Management).
