Introduction

1-1 Overview

SUPER P6DLS/P6DLE supports dual Pentium II 300/266/233 MHz
or higher processors. SUPER P6SLS/P6SLA supports single
Pentium II. They are based on Intel’s 440 LX chipset which enables
Accelerated Graphics Port (AGP), Wake-on-LAN, SDRAM, concur­rent PCI and Ultra DMA 33 MB/s burst data transfer rate.

All motherboards are ATX size and have 4 PCI slots, 3 ISA slots and
an AGP connector. SUPER P6DLS, P6DLE and P6SLS accommo­date a total of 1 GB EDO or 512 MB SDRAM memory with 4 168-pin
DIMM sockets. SUPER P6SLA accommodates a total of 768 MB
EDO or 384 MB SDRAM memory with 3 168-pin DIMM sockets.

AGP reduces contention with the CPU and I/O devices by broaden­ing the bandwidth of graphics to memory. It delivers a maximum of
532 MB/s 2x transfer mode which is quadruple the PCI speed!

Wake on LAN allows remote network management and configura­tion of the PC, even in off-hours when the PC is turned off. This
reduces the complexity of managing the network.

Other features that maximize customer satisfaction and simplicity in
managing the computer are PC 98-ready and support for Advanced
Configuration and Power Interface (ACPI). With PC Health Monitor­ing, you can protect your system from problems before they even
occur.

Included I/O on all motherboards are 2 EIDE ports, a floppy port, an
ECP/EPP parallel port, PS/2 mouse and PS/2 keyboard, 2 serial
ports, an infrared port and 2 USB ports. SUPER P6DLS and P6SLS
provide an on-board Adaptec 2940UW Ultra Wide SCSI controller
with fast data transfer rate of up to 40 MB/s.

1-2 PC Health Monitoring

This section describes the PC health monitoring features of SUPER
P6DLS/P6DLE/P6SLS/P6SLA. They have an on-board LM78 Sys­tem Hardware Monitor chip which can support PC health monitor­ing.

Seven On-Board Voltage Monitors for the CPU Core/s,
CPU I/O, +3.3V, ±±5V, and ±±12V

The on-board voltage monitor will scan the seven monitored volt­ages every second. Once a voltage becomes unstable, it will report
a warning or an error message on the screen. Users can adjust
the threshold of the monitored voltage to determine the sensitivity of
the voltage monitor.

Three-Fan Status Monitors with Firmware/Software
Control On/Off

The PC health monitor can check the RPM status of the cooling
fans. The on-board 3-pin CPU fan is controlled by the ACPI BIOS
and the ACPI enabled operating system. The thermal fans are con­trolled by the overheat detection logic.

CPU/Chassis Temperature Control

The thermal control sensor will monitor the real-time CPU tempera­ture. It will turn on the back-up fan whenever the CPU temperature
goes over the user-defined threshold. The overheat circuitry runs
independently from the CPU. It can still monitor the overheat condi­tion even if the CPU is in sleep mode. Once it detects that the CPU
temperature is too high, it will automatically turn on the back-up fan
to prevent any overheat damage to the CPU. The on-board chassis
thermal circuitry can monitor the overall system temperature and
alert users when the chassis temperature is too high.

1-17

SUPER P6DLS/P6DLE/P6SLS/P6SLA User’s Manual

CPU Fan Auto-Off in Sleep Mode

The CPU fan will turn on when the power is on. It can be turned off
when the CPU is in sleep mode. When the CPU is in sleep mode,
it means that it will not run at full power, thereby generating less
heat. For power saving purposes, the user can have the option to
shut down the CPU fan.

CPU Overheat Alarm and Control

This feature is available when used with SUPERMICRO's SUPER
Doctor Utility. The program will generate a beep sound via the
speaker when it detects CPU overheat condition. This overheat
condition can be configured by the user. The program can also give
an indication on the screen when the CPU overheats.

Chassis Intrusion Detection

The chassis intrusion circuitry can detect unauthorized intrusion to
the system. The chassis intrusion connector is located on JL1.
Attach a micro-switch to JL1. When the micro-switch is close, it
means that the chassis has been opened. The circuitry will then
alert the user with a warning message when the system is turned
on. The circuitry uses the on-board battery to power up. Even if the
whole system is powered off, the detection can still work properly.

System Resource Alert

This feature is available when used with Intel LANDesk Client Man­ager. The user can be notified of certain system events. For ex­ample, if the system is running low on virtual memory, the hard
drive space is not enough to save the data, you are then alerted of
the potential problems.

1-18

Chapter 1: Introduction

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 from losing your
valuable data.

Switching Voltage Regulator for the CPU Core

The switching voltage regulator for the CPU core can support up to
20A current, with auto-sensing voltage ID ranging from 2.1V to 3.5V.
This will allow the regulator to run cooler and make the system
more stable.

Intel LANDesk® Client Manager (LDCM) Support

As the computer industry grows, PC systems have become more
complex and harder to manage. Historically, only experts have
been able to fully understand and control these complex systems.
Today's users want manageable systems that interact automatically
with the user. Client Manager enables both administrators and cli­ents to:

• Review system inventory

• View DMI-compliant component information

• Back-up and restore system configuration files

• Troubleshoot

• Receive notification for system events

• Transfer files to and from client workstations

• Remotely reboot client workstations

1-3 ACPI/PC 98 Features

ACPI stands for 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 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, 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 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 both Windows 95 and Win­dows NT.

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 off and responds immediately to
user or other requests.

Slow Blinking LED for Sleep-state Indicator

When the CPU goes into a sleep state, the power LED will start
blinking to indicate that the CPU is in sleep mode. When the user
presses any key, the CPU will wake-up and the LED will automati­cally stop blinking and remain on.

1-20

Chapter 1: Introduction

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, the USB
keyboard will work like a normal keyboard during system boot-up.

Real Time Clock Wake-up Alarm (ATX power only)

The PC is perceived to be off when not in use, but is still capable of
responding to wake-up events due to a scheduled date and time of
the month. The user can set up a timer to wake-up or shutdown the
system at some predetermined time.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function
as a system suspend button. When the user press on 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 will cause the whole system to wake-up. During the
SoftOff state, the ATX power supply provides power to keep the re­quired circuitry on the system alive. In case the system malfunc­tions and you want to turn off the power, just press down on the
power button for 4 seconds. The power will turn off and no power is
provided to the motherboard.

External Modem Ring-on if System is in SoftOff State

Wake-up events can be triggered by a device such as the external
modem ringing when the system is in SoftOff state.

1-4 Chipset Overview

The 440LX chipset is developed by Intel as the ultimate Pentium II
processor platform targeted for emerging 3D graphics and multi­media applications. Along with System-to-PCI bridge integrated
with optimized DRAM controller and data path, the chipset intro­duces the Accelerated Graphics Port (AGP) interface. AGP is a high
performance, component level interconnect targeted at 3D applica­tions and is based on a set of performance enhancements to PCI.
The I/O subsystem portion of the 440LX platform is based on the
PIIX4, a highly integrated version of Intel's PCI-to-ISA bridge family.

The 440LX PCI/AGP Controller (PAC) system bus interface supports
up to two Pentium II processors. It provides an optimized 72-bit
DRAM interface (64-bit data plus ECC). This interface supports

3.3V DRAM technologies. The PAC provides the interface to a PCI

bus operating at 33 MHz. This interface implementation is compli­ant with the PCI Rev 2.1 Specification. The AGP interface is based
on the AGP Specification Rev 1.0. It can support up to 133 MHz
(532 MB/s) data transfer rates.

1-5 Wake-On-LAN (WOL)

Wake on LAN is defined as the ability of a management application
to remotely power up a computer which is powered off. Remote PC
setup, updates, and asset tracking can occur after hours and on
weekends so daily LAN traffic is kept to a minimum and users are
not interrupted.

The motherboards have a 3-pin header (WOL) used to connect to
the 3-pin header on the Network Interface Card (NIC) which has
WOL capability.

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 high

1-22

Chapter 1: Introduction

CPU clock rates like 300, 266, 233 MHz Pentium II processors.

SUPER P6DLS/P6DLE/P6SLS/P6SLA accommodates ATX power
supplies. Although most power supplies generally meet the spec­ifications required by the CPU, some power supplies are not ad­equate.

It is highly recommended that you use a high quality power supply.
Additionally, in areas where noisy power transmission is present,
you may choose to install a line filter to separate noise from the
computer. You can also install a power surge protector to help
avoid problems caused by power surges.

1-7 National Semiconductor Super I/O Controller

The National Semiconductor 87307 Super I/O Controller incorpo­rates an IDE control logic, two full function serial ports, an IEEE
1284 parallel port, industry standard floppy disk controller with 16
byte FIFO, Real Time Clock and an 8042 compatible keyboard con­troller all in one chip.

The IDE interfaces provide up to Mode 4 support. The two serial
ports are software compatible with the Fast UART 16550. The par­allel port is EPP (Enhanced Parallel Port) and ECP (Extended Ca­pabilities Port) compatible, including level 2 support. It includes a
protection circuit against damage caused when the printer is pow­ered up. EPP mode provides for greater throughput than Compat­ible or Extended modes by supporting faster transfer rates and a
mechanism that allows the host to address peripheral device regis­ters directly. Faster transfers are achieved by automatically gener­ating the address and data strobes. EPP is compatible with both
Compatible and Extended mode parallel-port devices.

1-8 AIC 7880 SCSI Controller

SUPER P6DLS/P6SLS has an on-board SCSI controller which is
100% compatible with an Adaptec 2940UW. Connectors include a
68-pin 16-bit SCSI connector (JA1) and a 50-pin 8-bit internal SCSI

1-23

SUPER P6DLS/P6DLE/P6SLS/P6SLA User’s Manual

connector (JA2). You can connect up to 15 devices (seven 8-bit
internal and eight 16-bit internal or external SCSI devices, or 15
Wide internal and external SCSI devices).

When Fast SCSI devices are connected, the total length of all
cables (internal and external) must not exceed 3 meters (9.8 ft) to
ensure reliable operation. If no Fast SCSI devices are connected,
the total length of all cables must not exceed 6 meters (19.7 ft).

Removing the Pentium II Processor

To remove the Pentium II processor from the motherboard, follow
these steps (the reverse of the installation process).

1. Disconnect the fan power cable from the motherboard. It is rec-

ommended to leave the cable connected to the processor.

2. Slide the clips on the supports backward to release the pegs in

the motherboard. Push the latches on the processor toward the
center of the processor until they click into place.

3. Lift one end of the processor until it is freed from Slot 1. Lift the

other end of the processor until it is freed from Slot 1. Lift the entire
processor (with the fan heatsink supports attached) until it is free
from the retention mechanism.

4. Remove the heatsink support pegs from the motherboard and

discard them. With one hand, squeeze together the two halves of
the peg on the bottom side of the motherboard. With the other
hand, pull the peg out of the hole in the motherboard. Do not reuse
the pegs.

When handling the Pentium II processor, avoid
placing direct pressure on the label area of the fan.

When removing the Pentium II processor, avoid pressing
down on the motherboard or components. Instead,
press down on the plastic connectors.

2-2 Static-Sensitive Devices

Static-sensitive electric discharge 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 static discharge.

2-6

Chapter 2: Installation

Precautions

• Use a grounded wrist strap designed for static discharge.

• Touch a grounded metal object before you remove the board
from the anti-static 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 system board and peripherals back into their anti-static
bags when not in use.

• Be sure your computer system’s chassis allows excellent
conductive contacts between its power supply, case, mounting
fasteners, and the system board for grounding purposes.

Unpacking

The system board is shipped in anti-static packaging to avoid static
damage. When unpacking the board, be sure the person handling
the board is static-protected.

2-4 Mounting the Motherboard in the Chassis

All the motherboards have standard mounting holes to fit different
types of chassis. Chassis may come with a variety of mounting
fasteners, made of metal or plastic. Although a chassis may have
both metal and plastic fasteners, metal fasteners are the most
highly recommended because they ground the system board to the
chassis. Therefore, use as many metal fasteners as possible for
better grounding.

2-6 Installing/Removing the DIMM Modules

SUPER P6DLS/P6DLE/P6SLS can accommodate a maximum of 1
GB EDO or 512 MB SDRAM, using standard 168-pin 3.3V unbuf­fered DIMM memory modules. SUPER P6SLA can accommodate a
maximum of 768 MB EDO or 384 MB SDRAM.

There are three types of EDO and SDRAM DIMM modules: x4, x8
and x16. If you are using the x4 type, you can populate the DIMM
slots with either 4 single-sided memory modules or 2 double-sided
memory modules. For memory configurations of 512 MB EDO
DIMMs or higher, it is recommended to use the x8 or x16 type of
memory. It is not recommended to mix EDO DIMM modules with
SDRAM DIMM modules.

There are no jumpers needed to configure the on-board memory.
Memory timing requires 70ns or faster for EDO memory. Refer to
Figure 2-7 and the instructions below for installing or removing
DIMM modules.

CAUTION

Exercise extreme care when installing or removing the

DIMM modules to prevent any possible damages.

DIMM Module Installation

1. Insert DIMM modules in Bank 0 through Bank 3 as required
for the desired system memory.

2. Insert each DIMM module vertically into its socket. Pay
attention to the two notches to prevent inserting the DIMM at a
wrong position. The component side of the DIMM module
must face the CPU socket. The latter statement is applicable
for DIMMs with components on one side only.

3. Gently press the DIMM module until it snaps upright into place
in the socket.

2-7 Connecting Parallel, Floppy and Hard Disk
Drives

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 the twisted wires always connects to drive B.

• An IDE hard disk drive requires a data ribbon cable with 40 wires,
and a SCSI hard disk drive requires a SCSI ribbon cable with 50
wires. A wide SCSI hard disk drive requires a SCSI ribbon cable
with 68 wires.

• A single IDE hard disk drive cable has two connectors to provide
for two drives. To select an IDE disk drive as C, you would nor­mally set the drive select jumper on the drive to DS1. To select
an IDE disk drive as D, you would normally set the drive select
jumper on the drive to DS2. Consult the documentation that
came with your disk drive for details on actual jumper locations
and settings.

• A single SCSI ribbon cable typically has three connectors to pro­vide for two hard disk drives and the SCSI adapter. (Note: most
SCSI hard drives are single-ended SCSI devices.) The SCSI ID
is determined by jumpers or a switch on the SCSI device. The
last internal (and external) SCSI device cabled to the SCSI
adapter must be terminated.

• Some drives require a special controller card. Read your disk
drive manual for details.

Troubleshooting

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you
have followed all of the procedures below and still need assistance,
refer to the ‘Technical Support Procedures’ and/or ‘Returning
Merchandise for Service’ section(s) in this chapter.

No Video

Use the following steps for troubleshooting your system configura­tion.

1. If you have no video, remove all the add-on cards and cables.

2. Check for shorted connections, especially under the
motherboard.

3. Check the jumpers settings, clock speed, and voltage set­tings.

4. Use the speaker to determine if any beep codes exist. Refer to
Appendix C of the AMI BIOS Reference Manual for details about
beep codes.

Chapter 3: Troubleshooting

NOTE

If you are a system integrator, VAR or OEM, a POST

diagnostics card is recommended for port 80h codes.

Refer to Appendix D.

Memory Error

If you encounter memory error, follow the procedures below.

1. Check to determine if DIMM modules are improperly installed.

2. Make sure that different types of DIMMs have not been in­stalled in different banks (e.g., a mixture of 2MB x 36 and 1
MB x 36 DIMMs in Banks 0).

3. Determine if different speeds of DIMMs have been installed in
the same or different banks, and the BIOS setup is configured
for the fastest speed of RAM used. It is recommended to use
the same RAM speed for DIMMs in different banks.

4. Check for bad DIMM modules or chips.

Losing the System’s Setup Configuration

1. Ensure that you are using a high quality power supply. A poor
quality power supply may cause the system to lose CMOS
setup. Refer to Chapter 1 of this manual for details.

2. If the above step does not fix the Setup Configuration prob­lem, contact your vendor for repair.

3-3

SUPER P6DLS/P6DLE/P6SLS/P6SLA User’s Manual

3-2 Technical Support Procedures

1. Go through the ‘Troubleshooting Procedures’ section in this
chapter of the manual before calling Technical Support.

2. BIOS upgrades can be downloaded from the SUPER BBS#
[phone], 24 hours a day, using 1200-14400 baud, 8
data bits, 1 stop bit and no parity. BIOS upgrades can also be
downloaded from our web site at http://www.supermicro.com.

Note: Not all BIOS can be flashed depending on the modifica­tions on the boot block code.

3. If you still cannot get the problem resolved, have the following
information ready before you call for technical support:

• BIOS release date/version

• System board serial number

• Product model name

• Invoice number and date

• System configuration

3-3 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is
required before any warranty service will be rendered. You can
obtain service by calling your vendor for a Returned Merchandise
Authorization (RMA) number. When returning to the manufacturer,
the RMA number should be prominently displayed on the outside of
the shipping carton, and mailed prepaid or hand-carried. Shipping
and handling charges will be applied for all orders that must be
mailed when service is complete.

This warranty only covers normal consumer use and does not cover
damages incurred in shipping or from failure due to the alternation,
misuse, abuse, or improper maintenance of products.

During the warranty period, contact your distributor first for any
product problems.
