Chapter 1: Introduction

1-2 Chipset Overview

The Intel® 860 chipset is a high performance, cost-effective and energy
efficient chipset designed for AGP/PCI/LPC computer systems based on
single or dual Intel® XeonTM 603-pin processors at a 400 MHz Front Side
(system) Bus speed.

Intel's 860 chipset consists of three major components: the Memory Control­ler Hub (MCH), the P64H and the I/O Controller Hub 2 (ICH2).

The MCH is optimized to provide superior performance between single or
dual Xeon CPUs and the dual channel RAMBUS memory operating at up to

3.2 GB/s data bus bandwidth. The MCH also supports a 4x AGP Pro accel-

erated video slot.

The P64H provides support for two PCI-64 slots and two SCSI hard disk
drive channels. It interfaces directly with the MCH.

The ICH2 is a highly integrated multifunctional I/O Controller Hub that pro­vides the interface to the PCI Bus and integrates many of the functions
needed in today’s PC platforms.

Memory Support and AGP

The MCH supports up to 2 GB of RDRAM. The RAMBUS dual channel
memory bus can support full duplex memory bandwidth transfers at up to

3.2 GB/s. Different memory module speeds (such as 600 MHz and 800

MHz) should not be mixed. Different RDRAM memory module sizes (such as
256 MB and 512 MB) may be used in Channel A and Channel B, but those
within each channel (Bank0 and Bank1) must be the same. The MCH also
provides full 4xAGP Pro capability for maximum bus utilization, including 2x
and 4x mode transfer rates.

The ICH2 provides extensive I/O support functions and capabilities, which
include Rev 2.2 compliant PCI with support for 33 MHz PCI operations, PCI­32 slots, ACPI Power Management Logic Support, an Enhanced DMA Con­troller, an Interrupt Controller and timer functions, an Integrated IDE control­ler supporting Ultra ATA100/66/33, a USB host interface with support for
four USB ports, two host controllers, an Integrated LAN Controller, a Sys­tem Management Bus (SMBus) with additional support for I2C devices, an
AC97 2.1 Compliant Link for Audio and Telephony codecs, a Low Pin Count
(LPC) interface, Firmware Hub (FWH) interface support and Alert On LAN
(AOL).

SUPER P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II User’s Manual

Recovery from AC Power Loss

The BIOS provides a setting that allows you to determine how your system
will respond when AC power is lost and then restored. You can choose
for the system to remain powered off (in which case you must activate the
power switch to turn it back on) or for it to return automatically to a power­on state. See the Power Lost Control setting in the BIOS chapter of this
manual to change this setting. The default setting is "Always OFF."

1-3 Special Features

Adaptec Raptor RAID Controller (P4DC6+/P4DC6+II only)

The P4DC6+ and P4DC6+II include a Raptor RAID controller to offer the high
degree of fault tolerance required by today's servers. A SO-DIMM socket
is included on the motherboard to plug a Raptor adapter card (not included)
into, which eliminates the need to use up a PCI slot to have RAID capability.
The Raptor RAID controller and adaptor utilizes a 64-bit bus, provides 0, 1,

0/1, 5, and 0/5 RAID levels and supports S.M.A.R.T. and SES/SAF-TE.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER

Chapter 1: Introduction

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and
will activate the thermal control fan whenever the CPU temperature ex­ceeds a user-defined threshold. The overheat circuitry runs independently
from the CPU. It can continue to monitor for overheat conditions even when
the CPU is in sleep mode. Once it detects that the CPU temperature is too
high, it will automatically turn the thermal control fan on to prevent any
overheat damage to the CPU. The onboard chassis thermal circuitry can
monitor the overall system temperature and alert users when the chassis
temperature is too high.

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It can be turned off
when the CPU is in sleep mode. When in sleep mode, the CPU will not run
at full power, thereby generating less heat.

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 is exceeded, both the overheat fan and the
warning LED are activated.

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager
(optional). It is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insuf­ficient hard drive space for saving the data, you can be alerted of the
potential problem.

Hardware BIOS Virus Protection

The system BIOS is protected by hardware so that no virus can infect the
BIOS area. The user can only change the BIOS content through the flash
utility provided by SUPERMICRO. This feature can prevent viruses from
infecting the BIOS area and destroying valuable data.

SUPER P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II User’s Manual

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to
20A of current and auto-sense voltage IDs ranging from 1.3v to 3.5v. This
will allow the regulator to run cooler and thus make the system more stable.

1-5 ACPI/PC99 Features

ACPI is an acronym meaning "Advanced Configuration and Power Inter­face." The ACPI specification defines a flexible and abstract hardware
interface that provides a standard way to integrate power management
features throughout a PC system, including its hardware, operating system
and application software. 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, telephones and stereos.

In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper­ating system-independent interface for configuration control. ACPI lever­ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with Windows
98, Windows NT and Windows 2000. You can check to see if ACPI has
been properly installed by looking for it in the Device Manager, which is
located in the "Control Panel" in Windows.

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.

1-16

Chapter 1: Introduction

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. The user can then
press any key on the system's keyboard to awaken the CPU, at which time
the LED will stop blinking and remain on.

USB Keyboard

If a USB keyboard is the only keyboard on the system, it can be enabled to
function like a standard feature keyboard during system boot-up.

Real Time Clock Wake-Up Alarm

Although the PC may be perceived to be off when not in use, it is still
capable of responding to preset wake-up events. In the BIOS, the user can
set a timer to awaken the system at a predetermined time.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a
system suspend button. With this feature enabled, the system will enter a
SoftOff state when the user depresses the power button. The monitor will
be suspended and the hard drive will spin down. Depressing the power
button again will cause the whole system to awaken. During the SoftOff
state, the ATX power supply provides power to keep the minimum 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 four
seconds. This will turn off the system completely with no main power
provided to the motherboard.

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. "External Modem Ring-On"
must be an included feature on the installed modem card when this feature
is desired and the corresponding setting must be enabled in the BIOS. Note
that external modem ring-on can only be used with an ATX 2.01 (or above)
compliant power supply.

SUPER P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II User’s Manual

Wake-On-LAN

Wake-On-LAN (WOL) is defined as the ability of a remote management ap­plication to power up a computer that is powered off. Remote PC setup,
updates and asset tracking can occur after hours and on weekends so that
daily LAN maintenance traffic can be kept to a minimum and LAN-system
users are not needlessly interrupted during normal work hours. The
motherboards have a 3-pin WOL header to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Wake-On-LAN
must be enabled in the BIOS. 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 especially important for processors that
have CPU clock rates of 1 GHz and above.

NOTE: Auxiliary 12v power (J23/24) is necessary to support Intel
Xeon CPUs. Failure to provide such extra power will result in the
CPUs becoming unstable after only a few minutes of operation.
See Section 2-6 for details on connecting the power supply cables.

The SUPER P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II 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 and 4-pin power connectors - an even higher wattage power
supply is recommended for high-load configurations. Your power supply
must also supply 1.5A for the LAN port. 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.

The functions of the disk drive adapter for 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 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.

disk drives and data transfer rates of 250 Kbps, 500 Kbps or 1 Mbps.

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 a baud rate of up to 115.2
Kbps as well as an advanced speed with baud rates of 250 Kbps, 500
Kbps or 1 Mbps to support higher speed modems.

The Super I/O supports one of the following: PC-compatible printer port
(SPP), bi-directional printer port (BPP), Enhanced Parallel Port (EPP) or Ex­tended Capabilities Port (ECP). The Super I/O provides functions that com­ply with ACPI (Advanced Configuration and Power Interface), which in­cludes support of legacy and ACPI power management through an 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 adjust flex­ibly to meet ISA PnP requirements, which suppport ACPI and Advanced
Power Management (APM).

2-1 Static-Sensitive Devices

Electric Static Discharge (ESD) can damage electronic components. To pre­vent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient 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 motherboard 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 motherboard.

Unpacking

The motherboard 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 in the order below to install the motherboard
into your system:

1. Install the processor and the heat sink.

2. Install the motherboard in the chassis.

3. Install the memory and add-on cards.

2-3 Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of chas­sis. Chassis may include a variety of mounting fasteners made of metal or
plastic. Although a chassis may have both types, metal fasteners are the
most highly recommended because they ground the motherboard to the chas­sis. For this reason, it is best to use as many metal fasteners as possible.

2-4 Installing RIMMs

CAUTION

Exercise extreme care when installing or removing RIMM

modules to prevent any possible damage.

Note: Check the Supermicro web site for a list of recommended memory
modules:
http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm

RIMM Installation (See Figures 2-2 and 2-3)

1.

Insert a pair of RDRAM modules (of the same type and size) into the

two RIMM slots of Bank 0. If needed, insert another pair of RDRAMs
(of the same type and size) into both slots of Bank1. If you populate
only the two slots of Bank0, then you need to populate both slots of
Bank1with "Continuity Modules" to close the signal loop. See
"RAMBUS Support" below for details on supported memory.

2. Insert each RDRAM module vertically into its slot. Pay attention to the

two notches along the bottom of the module to prevent inserting the
module incorrectly.

3. Gently press down on the RDRAM module until it snaps into place.

4. The P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II will support two

(2) or four (4) 600 or 800 MHz 184-pin RDRAM modules for a total of
up to 2 GB of system memory. Both ECC (Error Checking Correction)
and Parity Checking are supported.

RAMBUS Support (Important!)

The Memory Controller Hub (MCH) enables the use of RAMBUS in the
RIMM slots on the P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II. This
hub supports both ECC and non-ECC type memory, but you cannot mix both
types. (Check the Memory ECC Mode BIOS setting to enable the use of
ECC. See Section 1-2 for more on the MCH.)

2-8 Parallel Port, AGP, Floppy/Hard Disk and SCSI

Connections

Use the following information to connect the floppy and hard disk drive cables.

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two connectors to
provide for two floppy disk drives. The connector with twisted wires always
connects to drive A and the connector that does not have twisted wires
always connects to drive B.

• The 80-wire ATA66/100 IDE hard disk drive cable that came with your
system has two connectors to support two drives. This special cable should
be used to take advantage of the speed this advanced technology offers.
The blue connector connects to the onboard IDE connector interface and
the other connector(s) to your hard drive(s). The middle connector is for
the slave device and the remaining connector is for the master device.
Consult the documentation that came with your disk drive for details on
actual jumper locations and settings for the hard disk drive.

AGP Slot

The AGP Pro slot is backward compatible with AGP Pro and 4xAGP
graphics cards, which have fewer pins than AGP Pro cards. Because of
this, care must be taken when installing a graphics card into this slot, as
doing so incorrectly can damage your motherboard. For AGP Pro cards,
you should remove the orange sticker covering one end of the slot. For
other cards, leave this sticker in place and make sure your card does not
plug into the section it covers. A general rule of thumb is to make sure
your card fills the section of pins nearer the center of the motherboard first,
then the end toward the edge of the motherboard if there are more pins not
seated. If the I/O shield of your card is flush with the edge of the mother­board, the card should be inserted correctly.

diagnostics card is recommended. For I/O port 80h codes,

refer to Appendix B.

Memory Errors

1. Make sure the RIMM modules are properly and fully installed for the
amount of memory desired and RAMBUS terminators are installed in
any unused channel.

2. Determine if different speeds of RIMMs have been installed and verify
that the BIOS setup is configured for the fastest speed of memory
used. It is recommended that all RIMMs in the system have the same
speed.

3. Make sure you are using PC600 or PC800 compliant RDRAM.

4. Check for bad RIMM modules or slots by swapping modules among
slots and noting the results.

5. Make sure all memory modules are fully seated in their slots.

6. All RDRAM must be of the same speed (e.g. PC600 or PC800). Addi­tionally, the size of the memory bank sticks (e.g. 256 MB) must be
the same in any given memory channel.

Question: After flashing the BIOS my system does not have video.
How can I correct this?

Answer: If the system does not have video after flashing your new BIOS,

it indicates that the flashing procedure failed. To remedy this, first clear
CMOS per the instructions in this manual and retry the BIOS flashing proce­dure. If you still do not have video, please use the following BIOS Recov-
ery Procedure. First, make sure the JPWAKE jumper is disabled. Then,
turn your system off and place the floppy disk with the saved BIOS image
file (see above FAQ) in drive A. Press and hold <Alt> and <F2> at the same
time, then turn on the power keeping these keys pressed until your floppy
drive starts reading. Your screen will remain blank until the BIOS program
is done. If the system reboots correctly, then the recovery was success­ful. The BIOS Recovery Procedure will not update the boot block in your
BIOS.

Question: What's in the CD that came with my mainboard?

Answer: The supplied compact disc has quite a few drivers and programs

that will greatly enhance your system. We recommend that you review the
CD and install the applications you need. Applications on the CD include Intel
i860 chipset drivers for Windows plus security and audio drivers.

Question: Why can't I turn off the power using the momentary
power on/off switch?

Answer: The instant power off function is controlled in BIOS by the "Power

Button Mode" setting. When the "On/Off" feature is enabled, the mainboard
will have instant off capabilities as long as the BIOS has control of the
system. When either the "Standby" or the "Suspend" feature is enabled or
when the BIOS is not in control such as during memory count (the first
screen that appears when the system is turned on), the momentary On/Off
switch must be held for more than four seconds to shut down the system.
This feature is required to implement the ACPI features on the mainboard.

Question: I installed my microphone correctly but I can't record
any sound. What should I do?

Answer: Go to <Start> <Programs> <Accessories> <Entertainment> and

then <Volume Control>. Under the "Properties" tab, scroll down the list of
devices in the menu and check the box beside "Microphone".

Question: How do I connect the ATA66/100 cable to my IDE
device(s)?

Answer: The 80-wire/40-pin ATA66/100 IDE cable that came with your

system has two connectors to support two drives. This special cable must
be used to take advantage of the speed the ATA66/100 technology offers.
Connect the blue connector to the onboard IDE header and the other
connector(s) to your hard drive(s). Consult the documentation that came
with your disk drive for details on actual jumper locations and settings.

Question: Why am I getting the message "Pre-Boot Agent Failed"
on the top left of my screen during system boot-up?

Answer: This message will be displayed when the "Console Redirection"

setting in BIOS is either 1) disabled or 2) enabled and there is no modem
cable hooked up to the system. Note that this is not an error message, it is
just to let users that use console redirection know if their connection is
working. See the "Console Redirection" setting in the Advanced BIOS Set­tings section of BIOS for more information.

BIOS

4-1 Introduction

This chapter describes the AwardBIOS™ for the P4DC6/P4DC6+/P4DC6+II/
P4DCE/P4DCE+/P4DCE+II. The Award ROM BIOS is stored in a Flash
integrated circuit and can be easily upgraded using a floppy disk-based
program.

Note: Due to periodic changes to the AwardBIOS™, some settings may
have been added or deleted and might not yet be included in this manual.
Please refer to the Support Manual Download area of the Supermicro web
site http://www.supermicro.com for any changes to the BIOS that may not
be reflected in this manual.

System BIOS

The BIOS is the "Basic Input Output System" used in all IBM® PC, XT™, AT®,
and PS/2® compatible computers. The AwardBIOS™ Flash chip stores the
system parameters, such type of disk drives, video displays, etc. in its
CMOS memory (CMOS = Complementary Metal Oxide Semiconductor -- a
battery-maintained RAM in the BIOS). The CMOS memory, usually refer­enced as just "CMOS", requires very little electrical power. When the com­puter is turned off, a back-up battery provides power to the BIOS Flash
chip, enabling it to retain system parameters. Each time the computer is
powered-on the computer is configured with the values stored in the BIOS
RAM by the system BIOS, which gains control at boot-up.

How To Change the Configuration Data

The CMOS information that determines the system parameters may be
changed by entering the BIOS Setup utility. This Setup utility can be ac­cessed by pressing <Del> at the appropriate time during system boot (see
below).

Appendix A

AwardBIOS POST Messages

During the Power-On Self-Test (POST), the BIOS will check for errors. If an error is found
and a correction is needed, the BIOS will activate an alarm or display a message.

If a message is displayed, it will be accompanied by the following:

PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP

POST Beep Codes

Currently, there are two kinds of beep codes used in AwardBIOS. One code indicates
that a video error has occurred and that the BIOS cannot initialize the video screen to
display any additional information. This beep code consists of a single long beep followed
by two short beeps. The other code indicates that a Rambus error has occurred. This
beep code consists of a single long beep that sounds repeatedly.

Error Messages

One or more of the following messages may be displayed if the BIOS detects an error
during the POST. This list includes messages for both the ISA and the EISA BIOS.

CMOS BATTERY HAS FAILED

The CMOS battery is no longer functional. It should be replaced.

CMOS CHECKSUM ERROR

The CMOS hecksum is incorrect. This can indicate that CMOS has been corrupted. This
error may have been caused by a weak battery. Check the battery and replace if
necessary.

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

No boot device was found. This could mean that either a boot drive was not detected
or the drive does not contain the proper system boot files. Insert a system disk into Drive
A: and press <Enter>. If you assumed the system would boot from the hard drive, make
sure the controller is inserted correctly and all cables are properly attached. Also make
sure the disk has been formatted as a boot device. Then reboot the system.

DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP

The type of diskette drive installed in the system is different from the CMOS definition. Run
Setup to reconfigure the drive type correctly.

DISPLAY SWITCH IS SET INCORRECTLY

The display switch on the motherboard can be set to either monochrome or color. This
indicates that the switch is set to a different setting than indicated in Setup. Determine
which setting is correct, and then either turn off the system and change the jumper or
enter Setup and change the VIDEO selection.

DISPLAY TYPE HAS CHANGED SINCE LAST BOOT

Since last powering off the system, the display adapter has been changed. You must
configure the system for the new display type.

ERROR ENCOUNTERED INITIALIZING HARD DRIVE

The hard drive cannot be initialized. Be sure the adapter is installed correctly and all cables
are correctly and firmly attached. Also be sure the correct hard drive type is selected
in Setup.

ERROR INITIALIZING HARD DISK CONTROLLER

Cannot initialize the controller. Make sure the cord is correctly and firmly installed in the
bus. Be sure the correct hard drive type is selected in Setup. Also check to see if any
jumper needs to be set correctly on the hard drive.

FLOPPY DISK CNTRLR ERROR OR NO CNTRLR PRESENT

Cannot find or initialize the floppy drive controller. Make sure the controller is installed
correctly and firmly. If there are no floppy drives installed, be sure the Diskette Drive
selection in Setup is set to NONE.

KEYBOARD ERROR OR NO KEYBOARD PRESENT

Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys
are being pressed during boot up.

If you are intentionally configuring the system without a keyboard, set the error halt
condition in Setup to HALT ON ALL, BUT KEYBOARD. This will cause the BIOS to ignore
the missing keyboard and continue the boot.
