the system. If you encounter any problems, see Chapter 3, which describes

troubleshooting procedures for the video, the memory and the system setup stored

in CMOS.

Chapter 4 includes an introduction to BIOS and provides detailed information on

running the CMOS Setup utility.

Appendix A lists BIOS POST Error Codes.

Appendix B and Appendix C list Windows OS and Software Installation Instruc-

tions.

Note: TPM support is available for the PDSBA-Q+/PDSBA+/PDSBA only.

• A special Consideration on Overclocking: Setting a high CPU FSB Speed, using

a high DRAM Frequency, or selecting a high CPU V-Core voltage, memory voltage,

chipset voltage, ICH chipset voltage, or FSB termination voltage may cause the

system to become unstable. If this occurs, reset the setting to the default setting.

Extra fans may be needed for proper system cooling.

1-2 Chipset Overview

The Intel Q965-Express/G965/P965 Chipsets are specially designed for use with

Quad-core or Dual-core 1066/800/533 MHz processors. These chipsets consist of

two primary components: the Graphic Memory Controller Hub (GMCH)/Memory

Controller Hub (MCH) and the I/O Controller Hub (ICH8). Optimized for the Quad-

core/Dual-core Core2 Duo/E6000/E4000/Xeon 3000/Pentium

®

D/Pentium

®

4/Cel-

eron Processor via an LGA775 socket, the Q965-Express/G965/P965 provides the

performance and feature-set required for high-end UP quad-core and Dual-core pro-

cessor desktop solutions. (Note: GMCH is for the Q965-Express and G965 only.)

Graphic Memory Controller Hub (GMCH)/Memory

Controller Hub (MCH)

The GMCH/MCH manages the data ﬂ ow of the following interfaces: the CPU inter-

face (FSB), the System Memory interface (DRAM Controller) and the I/O Control-

ler through DMI (Direct Media) Interface. The MCH supports a FSB frequency of

1066/800/533 MHz using a scalable CPU. The Q965-Express/G965/P965 platforms

support the eighth generation I/O Controller Hub (Intel ICH8) to provide a variety

of I/O related functions.

Intel ICH8 System Features

The Intel ICH8 offers the data buffering and interface arbitration required for the

system to obtain peak performance. The Intel ICH8 supports up to six PCI-Express

root ports, up to four SATA ports at generation 1 and 2 speeds and up to ten USB

2.0 ports. In addition, the Intel ICH8 features High Deﬁ nition Audio controller which

supports extreme multimedia applications and various third party codecs.

PDSBA-Q+/PDSBA+/PDSBA/PDSBE User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the PDSBA-Q+/PDS-

BA+/PDSBA/PDSBE. The motherboard has an onboard System Hardware Monitor

chip that supports PC health monitoring.

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when

AC power is lost and then restored to the system. You can choose for the system

to remain powered off (in which case you must hit the power switch to turn it back

on) or for it to automatically return to a power on state. See the Power Lost Con-

trol setting in the BIOS chapter of this manual to change this setting. The default

setting is Always OFF.

Onboard Voltage Monitoring

The onboard voltage monitor will scan the following voltages continuously for the

CPU Core, +1.8V, +3.3V, +3.3V standby, +5V, Vbat and ±12V. 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.

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.

1-4 Power Conﬁ guration Settings

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

power settings.

Chapter 1: Introduction

1-11

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 will function like a normal

keyboard during system bootup.

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 to wake-up the whole system. 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.

1-5 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

PDSBA-Q+/PDSBA+/PDSBA/PDSBE accommodates 12V ATX

power supplies. It is strongly recommended that you use a high quality power sup-

ply 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.

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). Each UART includes a 16-byte send/receive FIFO, a programmable baud

rate generator, complete modem control capability and a processor interrupt sys-

tem. 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.
