System Block Diagram
Note: This is a general block diagram and may not exactly represent
the features on your motherboard. See the following pages for the
actual specifications of the motherboard.
1-8
1-2 Chipset Overview
The Intel 3000/3010 chipset is comprised of two primary components: the Memory
Controller Hub (MCH) and the I/O Controller Hub (ICH7R). With the capabilities
provided by the Intel 3000/3010 chipset, the PDSML-LN1+/PDSML-LN2+/PDSML-E+
provides the performance and feature-set required for cost-effective UP servers.
Memory Controller Hub (MCH)

The function of the MCH is to manage the data flow between four interfaces: the
processor interface (FSB), the System Memory Interface (DRAM Controller), the
Direct Media Interface (DMI) and the PCI Express Interface.
Using a scalable FSB Vcc_CPU, the MCH supports FSB speed up to 1066 MT/s
(266 MHz). Hyper-Threading Technology (HT) and FSB Dynamic Bus Inversion
(DBI) are among the Host Interface features supported. It integrates a system
memory DDR2 controller with two 64-bit interfaces and supports one or two chan-
nels of DDR2 SDRAM.
The I/O Controller (ICH7R) provides the data buffering and interface arbitration re-
quired for the system to operate efficiently. It also provides the bandwidth needed
for the system to maintain its peak performance. The Direct Media Interface (DMI)
provides the chip-to-chip connection between the MCH and the ICH7R.
The ICH7R supports up to four Serial ATA ports, six USB 2.0 ports and two IDE
devices. In addition, the ICH7R offers the Intel Matrix Storage Technology which
provides various RAID options for data protection and rapid data access. It also
supports the next generation of client management through the use of PROActive
technology in conjunction with Intel's next generation Gigabit Ethernet controller.
Intel ICH7 (ICH7R) System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest of the
system. Functions and capabilities include:
*Advanced Configuration and Power Interface, Version 2.0 (ACPI)
*Intel I/O External Design Specification (EDS)
* The Intel 3000 or Intel 3010 Memory Controller Hub (MCH) External Design
Specification (EDS)
*Intel I/O Controller Hub 7 (ICH7R) Thermal Design Guideline
1-9
1-3 Special Features

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 to change this setting. The default
setting is Last State.
1-4 PC Health Monitoring

This section describes the PC health monitoring features of the PDSML-LN1+/LN2+.
The motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for the CPU Cores, memory, +1.5V, +1.8V,
+3.3V, +5V, +12V, -12V, +5V Standby, VTT and Vbat
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. The
user can adjust the voltage thresholds to define the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management via BIOS (under
Hardware Monitoring in the Advanced Setting).
Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn
on the thermal control fan whenever the CPU temperature exceeds a user-defined
threshold. The overheat circuitry runs independently from the CPU. Once it de-
tects that the CPU temperature is too high, it will automatically turn on the thermal
fan control to prevent any possible CPU overheat. The onboard chassis thermal
circuitry can monitor the overall system temperature and alert the user 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 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.
1-10
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 exceeds the predefined temperature threshold, both overheat fan and
the warning LED will be activated.
System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor 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. You can also configure Supero
Doctor to provide you with warnings when the system temperature goes beyond
a pre-defined range.
1-5 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI specifi-
cation 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 2000, Windows XP and Windows
2003 Server.
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.
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. Pressing the power button again will
cause the whole system to wake-up. During the SoftOff state, the ATX power
1-11
supply provides power to keep the required circuitry in the system alive. In case
the system malfunctions and you want to turn off the power, just press 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 Standby or Off state. Note that external modem ring-on
can only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN
Wake-On-LAN is defined as the ability of a management application to remotely
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 motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
Note: Wake-On-LAN requires 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 PDSML-LN1+/PDSML-LN2+/PDSML-E+ can only accommodate a 24-pin ATX

power supply. Although most power supplies generally meet the specifications
required by the motherboard, some are inadequate. You should use one that will
supply at least 400W of power. In addition, the 12V 8-pin power connector is also
required for adequate power supply to the system. Also your power supply must
supply 1.5A of current for the Ethernet ports.
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specification 2.01 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 selection, a clock genera-
tor, 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). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which
support higher speed modems.
The Super I/O supports one 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 manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.
1-8 Intelligent Platform Management Interface (IPMI)

IPMI is a management interface that enables a user or administrator to remotely
access, monitor, diagnose and manage servers and networks. To use the IPMI
2.0 slot on this motherboard, use Supermicro’s AOC-SIM1U, AOC-SIM1U+ or the
AOC-SIMLC Intelligent Management module, and the IPMIView software utility that
is included in the package.
With the Raritan® KIRATM 100 Baseboard Management Controller (BMC) built-in,
the AOC-SIM1U/SIM1U+ and the AOC-SIMLC supports the 2D/VGA-compatible
Graphics Core with the PCI interface, Virtual Media, and Keyboard/Video/Mouse
(KVM) Redirection modules.
The KIRA 100 BMC interfaces with the host system via a PCI interface to com-
municate with the graphics core. It supports USB 2.0 and 1.1 for remote keyboard/
mouse/virtual media emulation. It also provides LPC interface to control Super IO
functions. The KIRA 100 is connected to the network via an external Ethernet PHY
module to provide network interfacing and management.

Installation
2-1 Electro-Static Sensitive Devices
Electro-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 electro-static build up.

• Touch a grounded metal object before removing the board from the anti-static
bag to discharge any electro-static build up.
• 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 anti-static 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.
• Use only the correct type of onboard CMOS battery. Do not install the onboard
battery upside down to avoid possible explosion.
Unpacking
The motherboard is shipped in anti-static packaging to avoid ESD damage. When

unpacking the board, make sure the person handling it is ESD protected.
Note: Be sure to mount the motherboard into the chassis before you install the CPU
onto the motherboard. All motherboards have standard mounting holes to fit different
types of chassis. Make sure that the locations of all the mounting holes for both
motherboard and chassis match and the metal standoffs click in or are screwed in
tightly. Use a screwdriver to secure the motherboard.
Caution: 1. Please do not use a force greater than 8 lb/inch on each mounting
screw during motherboard installation. 2. Some components are very close to the
mounting holes. Please take precautionary measures to prevent damage to these
components when installing the motherboard to the chassis.

PDSML-LN1+/PDSML-LN2+/PDSML-E+ User's Manual
2-2 Processor, Heatsink and Fan Installation
When handling the processor package, avoid placing

! direct pressure on the label area of the fan.
Notes: 1. Always connect the power cord last and always remove it before adding,
removing or changing any components. Make sure that you install the processor
into the CPU socket before you install the CPU heatsink.
2. Intel's boxed processor package contains the CPU fan and heatsink assembly. If
you buy a CPU separately, make sure that you use an Intel-certified multi-directional
heatsink and fan.
3. The LGA 775 heatsink and fan comes with a push-pin design and no tool is
needed for installation.
4. When purchasing an LGA 775 CPU or when receiving a motherboard with an LGA
775 CPU pre-installed, make sure that the CPU plastic cap is in place and none of
the CPU pins are bent; otherwise, contact the retailer immediately.

2-4 Installing DDR2 Memory

Memory Module Installation
Exercise extreme care when installing or removing memory mod-

ules to prevent any possible damage.
1. Insert each DDR2 memory module vertically into its slot. Pay attention to the
notch along the bottom of the module to prevent inserting the module incor-
rectly. (See support information below.)
2. Gently press down on the memory module until it snaps into place.
Support
The PDSML-LN1+/PDSML-LN2+/PDSML-E+ supports up to 8GB of dual chan-
nel, ECC/Non-ECC, unbuffered DDR2 667/533 MHz SDRAM. Both interleaved
and non-interleaved memory are supported, so you may populate any number
of DIMM slots. Populating DIMM#1A,DIMM#1B, and/or DIMM#2A, DIMM#2B
with memory modules of the same size and of the same type will result in dual
channel, two-way interleaved memory which is faster than the single channel,
non-interleaved memory. Note that when ECC memory is used, it may take
25-40 seconds for the VGA to display.
Notes:
1. Due to chipset limitation, 8GB Memory can only be supported by the following
operating systems:
32-Bit: Windows 2000 Advanced Server, Windows Server 2003 Enterprise
Edition; 64-Bit: Windows Server 2003 Standard x64 Edition, Windows XP
Professional x64 Edition, Windows Server 2003 Enterprise x64 Edition.
2. DIMM sizes of 256MB, 512MB, 1GB and 2GB are supported (240-pin, 1.8V
only).
3. Due to memory allocation to system devices, memory remaining available for
operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. Refer to the Memory Availability Table
on the following page for details.

Fan Headers
Fan Header
The PDSML-LN1+/PDSML-LN2+/ Pin Definitions
PDSML-E+ has six fan connections (Fan1 (Fan1-5)
to Fan6). Fan6 is designated as the CPU Pin# Definition
Cooling Fan. Note: all fans are 4-pin fans. 1 Ground (Black)
However, Pins 1-3 of the fan headers are 2 +12V (Red)
backward compatible with the traditional 3 Tachometer
3-pin fans. See the table on the right for 4 PWM_Control
pin definitions. The onboard fan speeds

are controlled by Thermal Management
in the BIOS Hardware Monitoring Setting.
When using Thermal Management setting,
please use all 3-pin fans or all 4-pin fans
on the motherboard. Please do not use
both 3-pin fans and 4-pin fans on the same
board. The default setting is "Disabled"
which will allow the onboard fans to run at
the full speed.

2-7 Jumper Settings

Explanation of
Jumpers
To modify the operation of the motherboard,

jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identified with
a square solder pad on the printed circuit
board. See the motherboard layout pages
for jumper locations.
Note: On two pin jumpers, "Closed"

means the jumper is on and "Open"
means the jumper is off the pins.

CMOS Clear
JBT1 is used to clear CMOS. Instead of
pins, this "jumper" consists of contact pads
to prevent the accidental clearing of CMOS.
To clear CMOS, use a metal object such
as a small screwdriver to touch both pads
at the same time to short the connection.
Always remove the AC power cord from the
system before clearing CMOS.

Note: For an ATX power supply, you must

completely shut down the system, remove
the AC power cord and then short JBT1
to clear CMOS. Do not use the PW_ON
connector to clear CMOS.

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.
Always disconnect the AC power cord before adding, changing or installing any
hardware components.
Before Power On
1. Check that the Standby PWR LED (LE1) is not lit. Note: If LE1 is on, it indi-
cates that Standby PWR is on. Be sure to turn off the power supply before
installing or removing the components.
2. Make sure the 8-pin 12v power connector at JPW2 is connected.
3. Make sure no short circuits between the motherboard and chassis.
4. Disconnect all ribbon/wire cables from the motherboard, including those for the
keyboard and mouse.
5. Remove all add-on cards.
6. Install a CPU and heatsink (Be sure that it is fully seated,) and then, connect
the chassis speaker and the power LED to the motherboard. Check all
jumper settings as well.
7. Make sure to use the correct type of CMOS battery as specified by the Manu-
facturer. Do not install the CMOS battery upside down to avoid possible
explosion.
No Power
1. Make sure no short circuits between the motherboard and the chassis.
2. Make sure that all jumpers are set to their default positions.
3. Check if the 115V/230V switch on the power supply is properly set.
4. Turn the power switch on and off to test the system.
5. The battery on your motherboard may be old. Check to verify that it still sup-
plies ~3VDC. If it does not, replace it with a new one.
No Video
1. If the power is on, but you have no video--in this case, you will need to re-
move all the add-on cards and cables first.
2. Use the speaker to determine if any beep codes exist. (Refer to Appendix A
for details on beep codes.)
3. Remove all memory modules and turn on the system. (If the alarm is on,
check the specs of the memory, reset the memory or try a different one.)
3-1
NOTE
If you are a system integrator, VAR or OEM, a POST diagnostics
card is recommended. For I/O port 80h codes, refer to App. B.
Memory Errors
1. Make sure that the DIMM modules are properly installed and fully seated in
the slots.
2. You should be using unbuffered, ECC/Non ECC DDR2-677/533 memory (see
the next page). Also, it is recommended that you use the same memory
speed for all DIMMs in the system. See Section 2-4 for memory limitations.
3. Check for bad DIMM modules or slots by swapping modules between slots
and noting the results.
4. Check the power supply voltage 115V/230V switch.

Losing the System’s Setup Configuration
1. Please be sure to use a high quality power supply. A poor quality power sup-
ply may cause the system to lose the CMOS setup information. Refer to
Section 1-6 for details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it still sup-
plies ~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fix the Setup Configuration problem, contact your
vendor for repairs.
3-2 Technical Support Procedures
Before contacting Technical Support, please make sure that you have followed all
the steps listed below. Also, note that as a motherboard manufacturer, Supermicro
does not sell directly to end-users, so it is best to first 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.
1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked

Question' (FAQ) sections in this chapter or see the FAQs on our web site
(http://www.supermicro.com/support/faqs/) before contacting Techni-
cal Support.
2. BIOS upgrades can be downloaded from our web site at
(http://www.supermicro.com/support/bios/).
3-2
Note: Not all BIOS can be flashed, some can be flashed, depending on the
modifications to the boot block code.
3. If you've followed the instructions above to troubleshoot your system, and still
cannot resolve the problem, then please contact Supermicro's technical support
and provide them with the following information:
• Motherboard model and PCB revision number
• BIOS release date/version (this can be seen on the initial display when your
system first boots up)
•System configuration
An example of a Technical Support form is on our web site at
(http://www.supermicro.com/support/contact.cfm).
4. Distributors: For immediate assistance, please have your account number ready
when placing a call to our technical support department. We can be reached
by e-mail at support@supermicro.com, by phone at:
(408) 503-8000, option 2, or by fax at (408)503-8019.

3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The PDSML-LN1+/PDSML-LN2+/PDSML-E+ supports up to 8 GB

of unbuffered, ECC/Non ECC, DDR2-677/533, two-way interleaved or non-
interleaved SDRAM. See Section 2-4 for details on installing memory.
Question: Why does Microsoft Windows XP (SP2) and Windows Vista show
less memory than what is physically installed?
Answer: Microsoft implemented a design change in Windows XP with Service

Pack 2 (SP2) and Windows Vista. This change is specific to the Physical Ad-
dress Extension (PAE) mode behavior which improves driver compatibility. For
more information, please read the following article at Microsoft's Knowledge
Base website at: http://support.microsoft.com/kb/888137.
Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are not
experiencing any problems with your system. Updated BIOS files are located
on our web site at http://www.supermicro.com/support/bios/. Please check our
BIOS warning message and the information on how to update your BIOS on our
web site. Select your motherboard model and download the BIOS (.rom) file to
your computer. Also, check the current BIOS revision and make sure that it is
newer than your BIOS before downloading. You may choose the zip file or the
.exe file. If you choose the zipped BIOS file, please unzip the BIOS file onto a
bootable device or a USB pen/thumb drive. To flash the BIOS, run the batch
3-3
file named “flash.bat” with the new BIOS .rom file from your bootable device or
USB pen/thumb drive. Use the following format:
F:\> flash xxxxxxxx.rom <Enter>
Note: Be sure to insert a space immediately after “flash” and use only the file
named “flash.bat” to update the BIOS.
When completed, your system will automatically reboot. If you choose the .exe
file, please run the .exe file under Windows to create the BIOS flash floppy disk.
Insert the floppy disk into the system you wish to flash the BIOS. Then, boot
the system to the floppy disk. The BIOS utility will automatically flash the BIOS
without any prompts. Please note that this process may take a few minutes to
complete. Do not be concerned if the screen is paused for a few minutes.
Warning: Do not shut down or reset the system while updating the BIOS to
prevent possible system boot failure!
When the BIOS flashing screen is completed, the system will reboot and will
show “Press F1 or F2”. At this point, you will need to load the BIOS defaults.
Press <F1> to go to the BIOS setup screen, and press <F9> to load the default
settings. Next, press <F10> to save and exit. The system will then reboot.
Note: The SPI BIOS chip installed on this motherboard is not removable. To
repair or replace a damaged BIOS chip, please send your motherboard to RMA
at Supermicro for service.
Question: What's on the CD that came with my 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 on the CD include chipset drivers
for Windows, security and audio drivers.
Question: How do I connect the ATA100/66 cable to my IDE device(s)?
Answer: The 80-wire/40-pin high-density ATA100/66 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 ATA100/66 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.

4-1 Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the PDSML-LN1+/
PDSML-LN2+/PDSML-E+. The Phoenix ROM BIOS is stored in a flash chip and
can be easily upgraded using a floppy disk-based program.
Note: Due to periodic changes to the BIOS, some settings may have been added or
deleted and might not yet be recorded in this manual. Please refer to the 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.
Warning: Do not shut down or reset the system while updating the
BIOS to prevent possible boot failure.
System BIOS
The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and
PS/2® compatible computers. The Phoenix BIOS flash chip stores the system
parameters, types of disk drives, video displays, etc. in the CMOS. The CMOS
memory requires very little electrical power. When the computer is turned off, a
backup 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 ROM 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 the
<Delete> key at the appropriate time during system boot. (See below.)
Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test. As
the memory is being tested, press the <Delete> key to enter the main menu of the
BIOS Setup utility. From the main menu, you can access the other setup screens,
such as the Security and Power menus. Beginning with Section 4-3, detailed de-
scriptions are given for each parameter setting in the Setup utility.

Appendix B: BIOS POST Codes
Appendix B
BIOS POST Codes
This section lists the POST (Power On Self Test) codes for the Phoenix BIOS. POST
codes are divided into two categories: recoverable and terminal.
Recoverable POST Errors
When a recoverable type of error occurs during POST, the BIOS will display an
POST code that describes the problem. BIOS may also issue one of the follow-
ing beep codes:
1 long and two short beeps - video configuration error

1 continuous long beep - overheat (Overheat LED will be on)
1 long beep and 1 short pause - memory not detected
Terminal POST Errors

If a terminal type of error occurs, BIOS will shut down the system. Before doing so,
BIOS will write the error to port 80h, attempt to initialize video and write the error
in the top left corner of the screen.
The following is a list of codes that may be written to port 80h.

* If the BIOS detects errors on 2C, 2E, or 30 (base 512K RAM error), it displays an
additional word-bitmap (xxxx) indicating the address line or bits that have failed. For
example, “2C 0002” means address line 1 (bit one set) has failed. “2E 1020" means
data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also
sends the bitmap to the port-80 LED display. It first displays the checkpoint code,
followed by a delay, the high-order byte, another delay, and then the loworder byte of
the error. It repeats this sequence continuously.

Appendix C: Software Installation
Appendix C
Software Installation
After all the hardware has been installed, you must first configure Intel's ICH7R
SATA RAID* before you install the Windows Operating System and other software
drivers.
Important Notes to the User:

Note 1: If you do not wish to configure onboard SATA RAID functions, please go
directly to Section C-3 for Operating System & Other Software Installation.
Note 2: This chapter describes RAID Configuration Instructions for the Intel ICH
RAID Controller designed for the Windows OS.
Note 3: GLAN2 is available on the PDSML-LN2+/PDSML-E+ only.
C-1 Introduction to Serial ATA and Parallel ATA

To configure the SATA RAID functions, you must first use the Intel ICH7R SATA
RAID Utility program to configure the RAID Level that you desire before installing
the Windows XP/2000/2003 operating system and other software drivers. (The
necessary drivers are all included on the Supermicro CD that came packaged with
your motherboard.) Note that the current version of the ICH7R SATA RAID Utility
can only support Windows XP/2000/2003 Operating Systems.
Serial ATA (SATA)

Serial ATA (SATA) is a physical storage interface that uses a single cable with a
minimum of four wires to create a point-to-point connection between devices. It is
a serial link, which supports transfer rates up to 3Gbps. Because the serial cables
used in SATA are thinner than the traditional cables used in Parallel ATA (PATA),
SATA systems have better airflow and can be installed in smaller chassis than
Parallel ATA. In addition, the cables used in PATA are limited to a length of 40cm,
while Serial ATA cables can be up to one meter in length. Overall, SATA provides
better functionality than PATA.
Introduction to Intel ICH7R Serial RAID

Located in the South Bridge of the 3000 chipset, the I/O Controller Hub (ICH7R)
provides the I/O subsystem with access to the rest of the system. It supports a 2-
channel UltraATA/100 Bus Master IDE controller (PATA) and four Serial ATA (SATA)
ports. The ICH7R supports the following PATA and SATA device configurations:
Legacy mode and Native mode.
C-1
RAID Configurations
The following types of RAID configurations are supported:
RAID 0 (Data Striping): this writes data in parallel, interleaved ("striped") sections
of two hard drives. Data transfer rate is doubled over using a single disk.
RAID1 (Data Mirroring): an identical data image from one drive is copied to another
drive. The second drive must be the same size or larger than the first drive.
RAID 10 (Striping & Mirroring): RAID 0 and 1 schemes are combined (without parity
information) to get the benefits of both.
RAID 5: both data and parity information are striped and mirrored across three or
more hard drives.
Intel Matrix Storage Technology
The Intel Matrix Storage Technology, supported by the ICH7R, allows the user to
create RAID 0 and RAID1 set by using only two identical hard disk drives. The
Intel Matrix Storage Technology creates two partitions on each hard disk drive and
generate a virtual RAID0 and RAID1 sets. It also allows you the change the HDD
partition size without any data.

Supero Doctor III
The Supero Doctor III program is a Web-base management tool that supports
remote management capability. It includes Remote and Local Management tools.
The local management is called the SD III Client. The Supero Doctor III program
included on the CDROM that came with your motherboard allows you to monitor
the environment and operations of your system. Supero Doctor III displays crucial
system information such as CPU temperature, system voltages and fan status. See
the Figure below for a display of the Supero Doctor III interface.
Note 1: The default user name and password are ADMIN.
Note 2: In the Windows OS environment, the Supero Doctor III settings take pre-
cedence over the BIOS settings. When first installed, Supero Doctor III adopts the
temperature threshold settings previously set in the BIOS. Any subsequent changes
to these thresholds must be made within Supero Doctor, since the SD III settings
override the BIOS settings. For the Windows OS to adopt the BIOS temperature
threshold settings, please change the SDIII settings to be the same as those set
in the BIOS.

Guide at: http://www.supermicro.com/PRODUCT/Manuals/SDIII/UserGuide.pdf. For
Linux, we will still recommend Supero Doctor II.
