1-2 Chipset Overview
Intel’s Lakeport (945G/P) chipset consists of two primary components: the Graphics
Memory Controller Hub (GMCH)/Memory Controller Hub (MCH) and the I/O Control-
ler Hub (ICH7). Optimized for the Celeron, Pentium 4, Pentium D processors in an
LGA775 Package, the Lakeport (945G/P) provides the performance and feature-set
required for high-end UP dual core processor desktop solutions.
Graphics Memory Controller Hub (GMCH)/Memory Controller
Hub (GMCH)
The GMCH/MCH supports high-performance integrated graphics and manage the
data flow of the following five 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 define 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 define an overheat temperature. When this
temperature reaches the pre-defined 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 Configuration Settings
This section describes features of your motherboard that deal with power and
power settings.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for a PC that is always on but appears
to be off and responds immediately to user or other re-quests.
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 depresses the power button, the system will enter
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Depressing the power button again will cause the whole system to wake-up. Dur-
ing 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 depress 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 specifications 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 Specification 1.1 or above. It is also required that the 12V
4-pin power connection (J41) be used for high-load configurations. In areas where
noisy power transmission is present, you may choose to install a line filter 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 floppy 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 floppy 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 Configuration
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 flexibly adjusted
to meet ISA PnP requirements, which support ACPI and APM (Advanced Power
Management).
