Introduction

1-1 Overview

SUPER S2DGU/S2DGR supports dual Pentium II Xeon 400/450 MHz proces­sors at 100MHz bus speed. These two motherboards are based on Intel’s
440GX chipset which enables 100 MHz system bus speed, Accelerated
Graphics Port (AGP), Wake-on-LAN, SDRAM, concurrent PCI and Ultra
DMA 33 MB/s burst data transfer rate.

While all of the motherboards are ATX form factor, S2DGR has 4 PCI and 2
ISA with one shared slot. SUPER S2DGU has 5 PCI and 2 ISA with one
shared slot. These motherboards have the AGP port, and can accommo­date 2 GB unbuffered SDRAM or registered SDRAM memory with 4 168-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, a PS/2 mouse and PS/2 keyboard, 2 serial ports, an infrared
port and 2 USB ports. SUPER S2DGR has integrated on-board Adaptec
7895 Dual UW SCSI controller. The dual channels allow data transfer rate
of 40 MB/s per channel. Additionally, this motherboard has a RAID port on­board to support the Adaptec ARO-1130SA/CA RAIDport II card for in­crease I/O performance and fault tolerance. SUPER S2DGU provides on­board Adaptec 7890 Ultra II LVD (Low Voltage Device) SCSI controller with
data transfer rate of up to 80 MB/s, and optional RAID III (ARO-1130SA2/
CA2).

Chapter 1: Introduction

1-2 Chipset Overview

The 440GX chipset, developed by Intel, is the ultimate processor platform
targeted for 3D graphics and multimedia applications. Along with System­to-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 440GX platform is based on the PIIX4E, a highly
integrated version of Intel's PCI-to-ISA bridge family.

The PCI/AGP and system bus interface controller (82443GX) 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 controller 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.

1-3 Slot 2 CPU

The Slot 2 CPU supports Intel's Pentium II Xeon CPU. This technology offers
larger L2 cache and allows L2 cache to run at full CPU speed.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of SUPER S2DGR
and S2DGU. They have an on-board 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 con­tinuously. 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.

1-9

SUPER S2DGR/S2DGU Manual

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

The PC health monitor can check the RPM status of the cooling fans. The
thermal fans are controlled by the overheat detection logic. Please Note:
The Tachometer reading is for JT1, JT2 and JT3 only.

Environment 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 user­defined 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 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 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 will not run at
full power, thereby generating less heat. For power saving purposes, the
user has the option to shut down the CPU fan.

CPU Overheat Alarm, LED and Control in S2DGR/S2DGU

This feature is available when the user enables the CPU overheat warning
function in the BIOS. The overheat alarm will activate when the CPU tem­perature exceeds the temperature configured by the user. When the over­heat alarm is activated both the overheat fan and LED are triggered.

Please Note: Alarm, fan and LED will remain on until computer is
restarted.

Chassis Intrusion Detection

The chassis intrusion circuitry can detect unauthorized intrusion to the sys­tem. The chassis intrusion connector is located on JL1. Attach a micro­switch to JL1. When the micro-switch is closed, 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. This feature is available when the
user is running Intel's LANDesk Client Manager, and SUPERMICRO's Super
Doctor.

System Resource Alert

This feature is available when used with Intel's 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.

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 loss of 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 1.8v 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

1-5 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 98 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 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 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, the USB keyboard
will work like a normal keyboard during system boot-up.

Real Time Clock Wake-up Alarm

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

1-12

Chapter 1: Introduction

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 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

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

1-6 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.
Note that Wake-On-Lan can only be used with an ATX power connector on­board.

1-7 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 CPU clock
rates like 233, 266, 300, 333, 350, 400 or 450 MHz Pentium II processor.

SUPER S2DGR/S2DGU 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 which
meets ATX power supply specification 2.01. Additionally, in areas where
noisy power transmission is present, you may choose to install a line filter

1-13

SUPER S2DGR/S2DGU Manual

to separate noise from the computer. You can also install a power surge
protector to help avoid problems caused by power surges.

1-8 Super I/O

The disk drive adapter functions of Super I/O chip include a floppy disk
drive controller compatible with the industry standard 82077/765, data
separator, write pre-compensation circuit, decode logic, data rate selection,
clock generator, drive interface control logic, and interrupt and DMA logic.
The wide range of functions integrated onto the Super I/O greatly reduced
the number of components required for interfacing with floppy disk drives.
The Super I/O supports four 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.

The Super I/O provides two high speed 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 up to 115.2 Kbps and also
advanced speed with baud rates of 230 K, 460 K, or 921 Kbps which
support higher speed modems.

The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP) and also Enhanced Parallel Port (EPP) and Extended Ca­pabilities Port (ECP). Also available, through the printer port interface pins,
are: Extension FDD Mode and Extension 2FDD Mode allowing one or two
external floppy disk drives to be connected.

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 SMI or SCI function pin. It also has auto power
management to reduce power consumption.

The Super I/O complies with Microsoft PC97 Hardware Design Guide.
IRQs, DMAs, and I/O space resources are flexible to adjust to meet ISA PnP
requirement. Moreover, it meets the specification of PC97's requirement in
the power management: ACPI and DPM (Device Power Management).

1-9 AIC -7890 Ultra II SCSI

Note: If you are using a low voltage differential Hard Drive, it is recommended you use LVD/SE Ultra
II SCSI cable. LVD/SE cable offers increased length, and can accommodate up to 15 devices.

1-14

Chapter 1: Introduction

SUPER S2DGU has an on-board Adaptec SCSI controller which is 100%
compatible with all major operating and hardware platforms. The Adaptec
AIC-7890 controller provides advanced PCI-to-SCSI Ultra2 SCSI host adapter
features in a 272-pin Ball Grid Array (BGA) package, as well as containing
an integrated dual mode (LVD/SE) transceiver. The AIC-7890 Ultra2 SCSI
chip connects to a 32-bit PCI bus. It is PCI 2.1 compliant, and fully supports
the power management requirements specified in Microsoft's PC 97 guide­lines and it provides SCAM level 2 support. The AIC-7890 functions with
Adaptec RAIDport III (ARO-1130CA2/1130SA/2) to deliver RAID functional­ity.

The AIC-7890 Ultra2 SCSI controller, used together with the AIC-3860 trans­ceiver, allows Ultra2 and single-ended devices to operate together on the
same SCSI bus without inpacting Ultra2 performance and cable lengths.
The AIC-7890 controller can support external High Voltage Differential
(HVD) transceivers only for Ultra data rates.

1-10 AIC -7895 MultiChannel

SUPER S2DGR has an on-board Adaptec SCSI controller which is 100%
compatible with all major operating and hardware platforms. PCI 2.1 and
SCAM Level 1 compliance are assured. Two independent UltraSCSI chan­nels provide a per channel data transfer rate of 40 MB/s. Connectors
include two 68-pin 16-bit Ultra Wide SCSI connectors (JA1/JA2) and a 50­pin 8-bit Ultra SCSI connector (JA3). 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).

AIC-7895 consolidates the functions of two SCSI chips, eliminating the need
for a PCI bridge. Reducing PCI bus loading enables system capabilities to be
expanded with additional PCI devices.

The AIC-7895 functions with Adaptec RAIDport II (ARO-1130SA/1130CA) to
deliver RAID functionality.

2-1 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.

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 static­protected.

This provides the processor with support against shock
and vibration.

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

2-1

SUPER S2DGR/S2DGU Manual

1. Installing metal standoffs:
Place the metal standoffs on the back of the motherboard tray. Be
sure the location of all the mounting holes for both motherboard and
chassis match. Make sure the metal standoffs click in or are
screwed in tightly. There are three additional metal standoffs,
specifically for the Slot 2 motherboard, required to mount the DRM
(Dual Retention Module). Please see Figure 2-1 for mounting hole
locations.

2. Mounting the motherboard onto the motherboard tray:
Except for the four Slot 2 mounting holes, use a Philips screwdriver
to secure motherboard onto the motherboard tray first.

3. Mounting fan and dual retention module (see figure 2-2):
Before mounting the retention base, you will need to first mount the
fan in the Fan Mount locations. Screw the base retention on the four
Slot 2 mounting holes. Note: The DRM needs to be bolted

through the motherboard to the chassis.

4. Placing fasteners:
Place a fastener on top of each side of the base, with arm on top
and screw holes underneath.

5. Installing caps on the Xeon processor as a handle bar:
When attaching the caps for each Xeon processor, make sure the
directions of the mounting screw holes on each cap face inside, in
order for the unit to easily slide in. Please test the configuration of
the units before mounting the caps.

6. Securing the Processor:
Slide in single/dual processor(s) making sure it sits on the Slot 2
socket. Then, using the DRM kit's screws, first place four screws
then secure the fastener tightly down.

2-3 Explanation and
Diagram of Jumper/
Connector

To modify the operation of the
motherboard, jumpers can be used
to choose settings. Jumpers cre­ate shorts between two pins and
change the function of the con­nector. Pin 1 is identified with a
square.

2-4 Changing the CPU
Speed

To change the CPU speed for a
Pentium II processor, change the
jumpers shown on Table 2-1. The
example on the right will show you
which CPU Core/Bus Ratio to use.
The general rule is to divide the
CPU speed by the bus speed (100
MHz). If you have a 400 MHz CPU,
dividing it by 100 will give you a
CPU Core/BUS Ratio of 4.0. After
determining the CPU Core/Bus Ra­tio, refer to Table 2-1 for settings
of JB1, JB2, JB3 and JB4.

2-5 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 Connecting Cables

After you have securely mounted
the motherboard to the chassis,
you are ready to connect the
cables. Attach power supply
cables to J32 for an ATX power
supply. See Table 2-2 for pin defi­nitions of an ATX power supply.

Secondary Power Connector

The Secondary Power Connector
is recommended when a heavy
load of peripherals have been

2-8 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 (or Master). To select an IDE disk
drive as D, you would normally set the drive select jumper on the drive to
DS2 (or Slave). 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

2-10

Chapter 2: Installation

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.

SUPER S2DGR/S2DGU Manual

No Power

1. Make sure the default jumper is on and CPU is correctly setup.

2. Turn power switch on and off to test system.

3. If power is still not on, turn off system power to move jumper setting
on JP20 from 2-3 to 1-2.

4. If moving jumper setting has not helped: Clear CMOS.

5. Check power supply voltage monitor. (Check power supply 115 V /
230 V switch)

No Video

Use the following steps for troubleshooting your system configuration.

1. If the power is on but you have no video, remove all the add-in
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 A for details about beep codes.

NOTE

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

tics card is recommended for port 80h codes. Refer to

Appendix B.

Memory Error

If you encounter memory error, follow the procedures below.

1. Check to determine if DIM 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, 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 the system.

4. Check for bad DIM modules or chips.

5. Try to install the minimum memory first (single bank).

3-2

Chapter 3: Troubleshooting

Losing the System’s Setup Configuration

1. Check the jumper JBT1 setting. 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.

3-2 Technical Support Procedures

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently
Asked Question' (FAQ) sections in this chapter of the manual or check
our web site FAQ (http:// www.supermicro.com) before contacting
Technical Support.

2. Take note that as a motherboard manufacturer Super Micro does not
sell directly to end-users, so it is best to check with your distributor or
reseller for troubleshooting services. They should know of any pos­sible problem(s) with the specific system configuration that was sold
to you.

3. BIOS upgrades can be downloaded from the SUPER BBS# (408) 895­2022, 24 hours a day, using 1200-28800 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 to
the boot block code.

4. If you still cannot resolve the problem, include the following information
when you e-mail Super Micro for technical support:

• BIOS release date/version

• System board serial number

• Product model name

• Invoice number and date

• System configuration
Due to the volume of e-mails we recieve and the time it takes to repli­cate problems, a response to your question may not be immediately
available. Please understand that we do not have the resources to
serve every end-user, however we will try our best to help all our
customers.

SUPER S2DGR/S2DGU Manual

3-3 Frequently Asked Questions

Question: What are the differences between the various memo­ries that the 440GX motherboard can support?

Answer: The 440GX integrates a main memory DRAM controller that

supports a 64-bit or 72-bit (64 bit memory data plus 8 ECC bits.) DRAM from
8 MB to 512 MB for SDRAM and from 8 MB to 2 GB SDRAM/registered DIMM.
DRAM types supported are either Synchronous DRAM (SDRAM) or Regis­tered DIM modules.

1. Mixing ECC and non-ECC will result in non-ECC operation.

EC/ECC is supported properly in the 440GX, only if all the memory are 72
bit wide. A system with a mixture of 64 and 72-bit wide memory will
disable ECC mode.

2. Registered SDRAM and unbuffered SDRAM cannot be mixed.

3. Mixing PC/100 DIMM and PC/66 DIMM will result in an unexpected
memory count or system errors.

4. User should populate the DIMM starting with the DIMM socket located
the furthest from the GX chip (U2 on S2DGR or U4 on S2DGU).

Question: How do I update my BIOS?

Answer: Update BIOS files are located on our web site at http://

www.supermicro.com. Please check the current BIOS revision and make
sure it is newer than your BIOS before downloading. Select your
motherboard model and download the BIOS file to your computer. Unzip the
BIOS update file and you will find three files: readme.txt (flash instructions),
sm2flash.com (BIOS flash utility), and the BIOS image file (xxxxxx.rom).
Copy these files onto a bootable floppy and reboot your system. It is not
necessary to set BIOS boot block protection jumpers on the motherboard.
At the DOS prompt, enter the command "sm2flash." This will start the flash
utility and give you an opportunity to save your current BIOS image. Flash
the boot block and enter the name of the update BIOS image file. NOTE: It
is important to save your current BIOS and rename it "super.rom" in case
you need to recover from a failed BIOS update. Select flash boot block,
then enter the update BIOS image. Select "Y" to start the BIOS flash proce-

3-4

Chapter 3: Troubleshooting

dure and do not disturb your system until the flash utility displays that the
procedure is complete. After updating your BIOS, please clear the CMOS
then load Optimal Values in the BIOS.

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 the flashing procedure failed. To remedy this, first clear the
CMOS per instructions in this manual and retry BIOS flashing procedure. If
you still do not have video, please use the following BIOS recovery proce­dure. Turn your system off and place the floppy disk with the saved BIOS
image file (see above FAQ) in drive A. Press and hold "CTRL" and "Home"
at the same time, then turn on power with these keys pressed until your
floppy drive starts reading. Your screen will remain blank until the BIOS
program is done. If system reboots correctly, then recovery is done.

Question: I have memory problems. What is the correct memory
to use and which BIOS setting should I choose?

Answer: The correct memory to use on the SUPER S2DGR/S2DGU is 168-

pin DIMM 3.3v non-buffered SPD (Serial Present Detection) SDRAM and
SDRAM. SPD SDRAM is preferred but is not necessary. IMPORTANT:
Please do not mix memory types; the results are unpredictable. If your
memory count is exactly half of the correct value, please go to the BIOS in
Chipset Setup and set "SDRAM AUTOSIZING SUPPORT" to Enabled. Change
between available options until one setting correctly displays your memory.

Question: Which Operating System (OS) supports AGP?

Answer: At present Windows 98 and Windows NT 5.0 are the only OS

that will have built-in support for AGP. Some AGP video adapters can run
Windows 95 OSR2.1 with special drivers. Please contact your graphics
adapter vendor for more details.

Question: Do I need the CD that came with your motherboard?

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 included on the CD
are PCI IDE Bus Master drivers for Windows 95 and Windows NT, 440GX
chipset drivers for Windows 95, and Super Doctor Monitoring software.

SUPER S2DGR/S2DGU Manual

Question: How do I install an on-board SCSI device controller for
my S2DGR motherboard.

Answer: First install 3 NT installation disks and then follow the on-screen

instructions to complete the procedure. "Safe mode" is best for this instal­lation.

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

Answer: The instant power off function is controlled by the BIOS. When

this feature is enabled in the BIOS, the motherboard will have instant off
capabilities as long as the BIOS has control of the system. When this
feature is disabled 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. This feature is required to implement ACPI features on the
motherboard.

Question: I see some of my PCI devices sharing IRQs, but the
system seems to be fine, is this correct or not?

Answer: Some PCI Bus Mastering devices can share IRQs without perfor-

mance penalties. These devices are designed to work correctly while shar­ing IRQs.

Question: When I connect my Ultra II LVD Hard Drive on the JA1
SCSI connection, the drive was not recognized by BIOS or it failed
to boot. Do I need a special cable?

Answer: Yes, for Ultra II LVD Drive, you need a special 68-pin cable with

active termination at the end of the cable, since Ultra II LVD Hard Drive does
not have termination on the drive.

3-4 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.

3-6

Chapter 3: Troubleshooting

Chapter 4

AMI BIOS

4-1 Introduction

This chapter describes the AMIBIOS for the Intel 440GX Pentium II Xeon 450/
400 MHz processors. The AMI ROM BIOS is stored in the Flash EEPROM
and is easily upgraded using a floppy disk-based program.

System BIOS

The BIOS is the basic input output system used in all IBM® PC, XT™, AT®,
and PS/2® compatible computers. The WinBIOS is a high-quality example of
a system BIOS.

Configuration Data

AT-compatible systems, also called ISA (Industry Standard Architecture)
must have a place to store system information when the computer is turned
off. The original IBM AT had 64 bytes of non-volatile memory storage in
CMOS RAM. All AT-compatible systems have at least 64 bytes of CMOS
RAM, which is usually part of the Real Time Clock. Many systems have 128
bytes of CMOS RAM.

How Data Is Configured

AMIBIOS provides a Setup utility in ROM that is accessed by pressing <Del>
at the appropriate time during system boot. Setup configures data in CMOS
RAM.

POST Memory Test

Normally, the only visible POST routine is the memory test. The screen that
appears when the system is powered on is shown on the next page.

An AMIBIOS Identification string is displayed at the left bottom corner of the
screen, below the copyright message.

Chapter 5: Running Setup

Parameter Description

Type The number for a drive with certain identification parameters.

Cylinders The number of cylinders in the disk drive.

Heads The number of heads.

Write The size of a sector gets progressively smaller as the track

Precompensation diameter diminishes. Yet each sector must still hold 512 bytes.

Write precompensation circuitry on the hard disk compensates for
the physical difference in sector size by boosting the write
current for sectors on inner tracks. This parameter is the track
number where write precompensation begins.

Sectors The number of sectors per track. MFM drives have 17 sectors

Capacity The formatted capacity of the drive is (Number of heads) x

per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.

(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)

booting record. The BIOS will not attempt to boot from any device which
is not selected as the boot device.

Try Other Boot Device

This option controls the action of the BIOS if all the selected boot devices
failed to boot. The settings for this option are Yes or No. If Yes is
selected and all the selected boot devices failed to boot, the BIOS will try
to boot from the other boot devices (in a predefined sequence) which are
present but not selected as boot devices in the setup (and hence not yet
been tried for booting). If selected as No and all selected boot devices
failed to boot, the BIOS will try not to boot from the other boot devices
which may be present but not selected as boot devices in setup.

Initial Display Mode

This option determines the display screen with which the POST is going

SERR# (System Error)

The settings for this option are Enabled or Disabled. Set to Enabled to
enable the SERR# signal on the bus. GX asserts this signal to indicate a
system error condition. SERR# is asserted under the following condi­tions:

- In an ECC configuration, the GX asserts SERR#, for single bit (correctable) ECC errors or multiple bit
(non-correctable) ECC errors if SERR# signaling is enabled via the ERRCMD control register. Any ECC
errors received during initialization should be ignored.

- The GX asserts SERR# for one clock when it detects a target abort during GX initiated PCI cycle

- The GX can also assert SERR# when a PCI parity error occurs during the address or data phase

- The GX can assert SERR# when it detects a PCI address or data parity error on AGP

- The GX can assert SERR# upon detection of access to an invalid entry in the Graphics Aperature
Translation Table

- The GX can assert SERR# upon detecting an invalid AGP master access outside of AGP aperture and
outside of main DRAM range (i.e. in the 640k - 1M range or above TOM)

- The GX can assert SERR# upon detecting an invalid AGP master access outside of AGP aperture.

Memory Autosizing Support

The dynamic detection and sizing of SDRAM and EDO is performed by the
BIOS in a system populated with memory which has no SPD information.
When set to Enable, memory does not have the SPD information. The
settings for this option are Auto or Enable.

DRAM Integrity Mode

The settings for this option are None, EC or ECC Hardware. Note: For
ECC memory only. See the table below to set the type of system
memory checking.

Setting Description

None No error checking or error reporting is done.

EC Multibit errors are detected and reported as parity

errors. Single-bit errors are corrected by the chipset.
Corrected bits of data from memory are not written
back to DRAM system memory.

ECC Multibit errors are detected and reported as parity
Hardware errors. Single-bit errors are corrected by the

chipset and are written back to DRAM system memory.
If a soft (correctable) error occurs, writing the fixed
data back to DRAM system memory will resolve the
problem. Most DRAM errors are soft errors. If a hard
(uncorrectable) error occurs, writing the fixed data
back to DRAM system memory does not solve the
problem. In this case, the second time the error

5-9

BIOS User's Manual

occurs in the same location, a Parity Error is reported,
indicating an uncorrectable error. If ECC is selected,
AMIBIOS automatically enables the System
Management Interface (SMI). If you do not want to
enable power management, set the Power
Management/APM option to Disabled and set all
Power Management Setup timeout options to

Disabled. To enable power management, set Power
Management/APM to Enabled and set the power

management timeout options as desired.

DRAM Refresh Rate

This option specifies the interval between Refresh signals to DRAM

Search for MDA (Monochrome Adapter) Range (B0000h-B7FFFh)
Resources

Legacy support requires the ability to have a second graphics controller
(monochrome) in the system. In an AGP system, accesses in the normal
VGA range are forwarded to the AGP bus. Since the monochrome
adapter may be on the PCI (or ISA) bus, the GX must decode cycles in
the MDA range and forward them to PCI. The settings for this option are
Yes or No. Set this option to Yes to let AMIBIOS search for MDA
resources.

AGP Multi-Trans Timer (AGP Clks)

This option sets the AGP multi-trans timer. The settings are in units of

BIOS Error Beep Codes & Messages

During the POST (Power-On Self-Test) routines, which are performed
each time the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to
continue the boot-up process. The error messages normally appear on
the screen.

Fatal errors are those which will not allow the system to continue the
boot-up procedure. If a fatal error occurs, you should consult with your
system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of audible
beeps. The numbers on the fatal error list, on the following page,
correspond to the number of beeps for the corresponding error. All
errors listed, with the exception of #8, are fatal errors.
