Introduction
1-2 Chipset Overview
The Intel E7501 chipset is a high-performance chipset with a performance
and feature-set designed for mid-range, dual processor servers. The
E7501 chipset consists of four major components: the Memory Controller
Hub (MCH), the I/O Controller Hub 3 (ICH3), the PCI-X 64-bit Hub 2.0 (P64H2)
and the 82808AA Host Channel Adapter (VxB).
The MCH has four hub interfaces, one to communicate with the ICH3 and
three for high-speed I/O communications. The MCH employs a 144-bit wide
memory bus for a DDR-266 memory interface, which provides a total band-
width of 3.2 GB/s. The ICH3 interface is a 266 MB/sec point-to-point con-
nection using an 8-bit wide, 66 MHz base clock at a 4x data transfer rate.
The P64H2 interface is a 1 GB/s point-to-point connection using a 16-bit
wide, 66 MHz base clock at a 8x data transfer rate.
The ICH3 I/O Controller Hub provides various integrated functions, including
a two-channel UDMA100 bus master IDE controller, USB host controllers, a
System Management Bus controller and an AC'97 compliant interface.
The P64H2 PCI-X Hub provides a 16-bit connection to the MCH for high-
performance IO capability and two 64-bit PCI-X interfaces.
1-3 Special Features
ATI Graphics Controller
The X5DMS-6GM/X5DMS-8GM has an integrated ATI video controller based
on the Rage XL graphics chip. The Rage XL fully supports sideband ad-
dressing and AGP texturing. This onboard graphics package can provide a
bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus.
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 Control setting in the Advanced BIOS Setup
section (Peripheral Device Configuration) to change this setting. The de-
fault setting is Always On.

Introduction
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
X5DMS-6GM/X5DMS-8GM. The motherboard has an onboard System Hard-
ware Monitor chip that supports PC health monitoring.
Onboard Voltage Monitors for the CPU Cores, Chipset
Voltage, +3.3V, +5V, +12V and +3.3V Standby
An onboard voltage monitor will scan these voltages continuously. Once a
voltage becomes unstable, a warning is given or an error message is sent
to the screen. Users can adjust the voltage thresholds to define the
sensitivity of the voltage monitor.
Fan Status Monitor with Firmware/Software On/Off Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin CPU and chassis fans are controlled by the power manage-
ment functions. The thermal fan is controlled by the overheat detection
logic.
CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It continues to operate
when the system enters Standby mode. When in sleep mode, the CPU will
not run at full power, thereby generating less heat.
CPU Overheat LED
JOH1 is a header used to connect to a CPU overheat LED. When the CPU
temperature becomes too high, both the overheat alarm and the warning
LED are activated.
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager
(optional). LDCM is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insuf-
ficient hard drive space for saving the data, you can be alerted of the
potential problem.

Chapter 1: Introduction
1-11
Introduction
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 1.4V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft-
ware. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers. This also
includes consumer devices connected to the PC such as VCRs, TVs, tele-
phones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win-
dows 2000 and Windows NT 5.0.
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.

SUPER X5DMS-6GM/X5DMS-8GM User’s Manual

Introduction
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button to make the system 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 re-
quired 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. This option can be set in the Power section of the BIOS Setup
routine.
External Modem Ring-On
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.
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to re-
motely power up a computer that is powered off. Remote PC setup, up-
dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Note that Wake-
On-LAN can only be used with an ATX 2.01 (or above) compliant power
supply.
1-6 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.
The SUPER X5DMS-6GM/X5DMS-8GM accommodates ATX power supplies.
Although most power supplies generally meet the specifications required by
the CPU, some are inadequate. You should use one that will supply at least
400W of power and includes the additional +12V, 8-pin power connector -
an even higher wattage power supply is recommended for high-load con-
figurations. Also your power supply must provide 1.5A, which is needed
for the LAN

Chapter 1: Introduction
1-13
Introduction
port(s).
NOTE: Auxiliary 12v power (J15) is necessary to support Intel Xeon
CPUs. Failure to provide this extra power will result in the CPUs
becoming unstable after only a few minutes of operation. See
Section 2-5 for details on connecting the power supply cables.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 or above. It must also be SSI
compliant (info at http://www.ssiforum.org/). Additionally, 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.
1-7 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 selec-
tion, 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 floppy disk
drives. The Super I/O supports 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.
Each UART includes a 16-byte send/receive FIFO, a programmable baud
