1-2 Chipset Overview
The H8DA8/H8DAE/H8DAR-8/H8DAR-i serverboard is based on the AMD-8131TM
chipset. This chipset is composed of two main components: the AMD-8131
HyperTransport
The AMD-8131 chipset provides high performance and an excellent feature-set
for multi-processor server solutions. Controllers for the system memory are built
directly into the processors.
8131 HyperTransport PCI-X Tunnel
This hub includes AMD-specifi c technology that provides two PCI-X bridges with
each bridge supporting a 64-bit data bus as well as separate PCI-X operational
modes and independent transfer rates. Each bridge supports up to fi ve PCI masters
that include clock, request and grant signals. This hub connects to the processors
and through them to system memory. It also interfaces directly with the SCSI and
Ethernet controllers.
TM
PCI-X Tunnel and the AMD-8111TM HyperTransportTM I/O Hub.
8111 HyperTransport I/O Hub
The 8111 I/O hub provides the interface between the 8131 hub and various subsystems including the Winbond Super I/O functions, the onboard graphics, the IDE
controller and the USB ports.
HyperTransport Technology
HyperTransport technology is a high-speed, low latency point to point link that was
designed to increase the communication speed by a factor of up to 48x between
integrated circuits. This is done partly by reducing the number of buses in the
chipset to reduce bottlenecks and by enabling a more effi cient use of memory in
multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.

Chapter 1: Introduction
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the H8DA8/H8DAE/
H8DAR-8/H8DAR-i. The serverboard has an onboard System Hardware Monitor
chip that supports PC health monitoring.
Onboard Voltage Monitors for the CPU Core voltages, Hyper
Transport voltage (1.2V), memory voltage (2.5V), DDR temination
voltage (1.25V), +3.3V, +5V, ±12V, +1.8V, +5V stby and +3.3V stby
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 moni-
tor. Real time readings of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware/Software Speed Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by thermal management via BIOS.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat/Fan Fail warning
function in the BIOS. This allows the user to defi ne an overheat temperature. When
this temperature is exceeded or when a fan failure occurs, then, the Overheat/Fan
Fail warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to 80A and
auto-sense voltage IDs ranging from 0.875 V to 1.6V. This will allow the regulator
to run cooler and thus make the system more stable.

H8DA8/H8DAE/H8DAR-8/H8DAR-i User’s Manual
1-4 Power Confi guration Settings
This section describes the features of your serverboard 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 requests.
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 a USB keyboard is the only keyboard in the system, it 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. 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 depress and hold the power button for 4 seconds. The power
will turn off and no power will be provided to the serverboard.
Wake-On-LAN (JWOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and access
tracking can occur after hours and on weekends so that daily LAN traffi c is kept
to a minimum and users are not interrupted. The serverboard has a 3-pin header
(JWOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
1-14

WOL capability. Wake-On-LAN must be enabled in BIOS. Note that Wake-On-LAN
can only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-Ring Header (JWOR)
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 H8DA8/H8DAE/H8DAR-8/H8DAR-i accommodates 12V ATX power supplies.
Although most power supplies generally meet the specifi cations required by the
CPU, some are inadequate. A 2 amp current supply on a 5V Standby rail is strongly
recommended.
It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply Specifi cation 1.1 or above. Additionally, 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.
Warning: To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.

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 generator, 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 includes 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 management 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).

2-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic com ponents. T o prevent damage to your system board, it is important to handle it very carefully. The following
measures are generally suffi cient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic
bag.
• Handle the board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the serverboard and peripherals back into their antistatic bags when not in
use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.
• Use only the correct type of CMOS onboard battery as specifi ed by the manufac-
turer. Do not install the CMOS onboard battery upside down, which may result
in a possible explosion.
Unpacking
The serverboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.
Installation Procedures
Follow the procedures as listed below to install the serverboard into a chassis:
1. Install the processor(s) and the heatsink(s).
2. Install the serverboard in the chassis.
3. Install the memory and add-on cards.
4. Finally, connect the cables and install the drivers.

2-2 Processor and Heatsink Installation
Exercise extreme caution when handling and installing the processor. Always connect the power cord last and always remove it before adding, removing or changing any hardware components.
Installing the CPU Backplates
Two CPU backplates (BKT-0004) are included in the retail box. The backplates
prevent the CPU area of the serverboard from bending and provide a base for attaching the heatsink retention modules. To install, begin by peeling off the release
paper to expose the adhesive. On the underside of the serverboard, locate the two
holes on either side of the CPU socket. Attach the adhesive side of the backplate
to the board by inserting the standoffs into the two holes and applying light pressure
so that the backplate sticks to the underside of the board. Repeat for the second
CPU socket. See Figure 2-1.
Installing the Processor (install to the CPU#1 socket fi rst)
1. Lift the lever on CPU socket #1 until
it points straight up.
2. Use your thumb and your index fi n-
ger to hold the CPU. Locate pin 1 on
the CPU socket and pin 1 on the CPU.
Both are marked with a triangle.
3. Align pin 1 of the CPU with pin 1
of the socket. Once aligned, carefully
place the CPU into the socket. Do not
drop the CPU on the socket, move the
CPU horizontally or vertically or rub the
CPU against the socket or against any
pins of the socket, which may damage
the CPU and/or the socket.
