CAUTION
Lithium Battery: See "Replacing the Backup Battery" on page 68 of this
product guide for instructions on replacing and disposing of the Lithium
Battery.
Processor
Each Intel Pentium III Xeon processor is packaged in a single edge contact (S.E.C.) cartridge. The
cartridge includes the processor core with an integrated 32 KB primary (L1) cache, the secondary
(L2) cache, a thermal plate, and a plastic cover.
The processor core and L2 cache components are on a pre-assembled printed circuit board,
approximately 5 inches by 6 inches. The L2 cache and processor core L1 cache interface use a
private bus isolated from the processor host bus. The L2 cache bus operates at the processor core
frequency.
Each S.E.C. cartridge connects to the baseboard through a 330-pin SC330.1 compliant edge
connector. A retention module attached to the baseboard secures the cartridge. Depending on
configuration, the system supports one to four processors.
The processor external interface is MP-ready and operates at 100 MHz. The processor contains a
local Advanced Configuration and Power Interface (APIC) unit for interrupt handling in
multiprocessor (MP) and uniprocessor (UP) environments.
Table 2. SKA4 Pentium Xeon Processor Family Support Matrix

512k, 1M, 2M Yes
The L2 cache is located on the substrate of the S.E.C. cartridge. The cache:
• Is offered in 512 KB, 1 MB, and 2 MB configurations
• Has ECC
• Operates at the full core clock rate
Baseboard Description 15
Memory
Main memory resides on an add-in board, called a memory module, designed for the SKA4
baseboard. The memory module contains slots for 16 DIMMs, each of which must be at least
64 MB, and is attached to the baseboard through a 330-pin connector, called the Memory
Expansion Card Connector (MECC). The memory module supports PC-100 compliant registered
ECC SDRAM memory modules. The ECC used for the memory module is capable of correcting
single-bit errors (SBEs) and detecting 100 percent of double-bit errors over one code word. Nibble
error detection is also provided.
System memory begins at address 0 and is continuous (flat addressing) up to the maximum amount
of DRAM installed (exception: system memory is noncontiguous in the ranges defined as memory
holes using configuration registers). The system supports both base (conventional) and extended
memory.
• Base memory is located at addresses 00000h to 9FFFFh (the first 1 MB).
• Extended memory begins at address 0100000h (1 MB) and extends to 3FFFFFFFFh (16 GB),
which is the limit of supported addressable memory. The top of physical memory is a
maximum of 16 GB (to 3FFFFFFFFh).
Memory amounts from 256 MB to 16 GB of DIMM are supported, with a 64/72-bit
four-way-interleaved pathway to main memory, which is also located on the module. Therefore,
data transfers between MADPs and DIMMs is in four-way interleave fashion. Each of the four
DIMMs must be populated in a bank. The 16 slots are divided into four banks of four slots each.
They are labeled A through D. Bank A contains DIMM sockets A1, A2, A3, and A4. Banks B, C,
and D each contain 4 DIMM sockets and are named in the same fashion. There are silk screens on
the module next to each DIMM socket to label its bank number. For the best thermal results,
populate the banks from A to D. For example, populate bank A and then bank B. For best
performance results, populate adjacent banks. For example, populate bank A and then bank C.

NOTE
✏
Based on the chipset, addressable memory can be extended to 16 GB.
However, some server systems are not thermally configured to support all
16 GB. Consult the documentation accompanying your server system to
determine the maximum memory configuration of your server system.
Some operating systems and application programs use base memory while others use both
conventional and extended memory. Examples are
†
• Base memory: Microsoft MS-DOS
†
UNIX
• Conventional and extended memory: IBM OS/2, Microsoft Windows NT, and various UNIX
MS-DOS does not use extended memory; however, some MS-DOS utility programs like RAM
disks, disk caches, print spoolers, and windowing environments use extended memory for better
performance.
The BIOS automatically detects, sizes, and initializes the memory array, depending on the type,
size, and speed of the installed DIMMs, and reports memory size and allocation to the system via
configuration registers.

Baseboard Description 17
Peripherals
Super I/O Chip (SIO)
The National† PC97317VUL Super I/O Plug and Play Compatible with ACPI Compliant
Controller/Extender device supports two serial ports, one parallel port, diskette drive, and
PS/2-compatible keyboard and mouse. The system provides the connector interface for each port.
Serial Ports
Both serial ports can be relocated. Each serial port can be set to one of four different COMx ports,
and each can be enabled separately. When disabled, serial port interrupts are available to add-in
boards.
Parallel Port
The SKA4 baseboard provides a 25-pin Parallel Port connector. The SIO provides an IEEE
1284-compliant 25-pin bi-directional parallel port. BIOS programming of the SIO registers enable
the parallel port, and determine the port address and interrupt. When disabled, the interrupt is
available to add-in cards.
Add-in Board Slots
The baseboard has eight slots for PCI add-in boards supported by three PCI bus segments called
PCI-A, PCI-B, and PCI-C. There are two on PCI-A, four on PCI-B, and two on PCI-C. PCI-C
supports half-length boards (5.6" to 6.3") only; the other slots support full-length boards.
The two slots for the PCI bus segment PCI-C consume a maximum of 375 mA of standby current
on a 3.3V AUX power line. The remaining six slots do not have any 3.3V Aux capabilities.
Both PCI segments A and B allow you to add, remove, or replace PCI add-in boards installed in
their slots without interrupting normal operation or powering down the system. To use this PCI
Hot-Plug (PHP) feature, a server system requires PCI Hot-Plug software and PCI Hot-Plug capable
add-in boards. PCI Hot-Plug software usually is a driver loaded for a specific operating system.
Each Hot-Plug PCI slot has two LEDs. The green LED indicates the state of power on each slot.
The amber LED indicates an error condition with that slot.

66 MHz. The PCI controller manages PHP functionality for the PCI segment it resides on. There
is a DesotoE2 controller on PCI segments A and B. The DesotoE2 PHP controller is:
• ACPI compliant
†
• Compatible with Compaq’s
PHP controller design
• Supports either a 3.3 V or 5 V PCI bus
The DesotoE2 is responsible for:
• Managing power application and removal to individual slots
• Properly resetting newly-added PCI boards prior to bringing the board online
• Managing connection and disconnection of the PCI signals between the P CI bus and the add-
in board
• Managing seamless addition and removal of individual PCI add-in boards without impacting
bus functionality
IDE Interface
The Open South Bridge (OSB4) acts as a PCI-based fast IDE controller. The controller supports
programmed I/O and bus master transfers. While the OSB4 supports two IDE channels, the SKA4
baseboard uses only the primary IDE channel and provides a single 40 pin IDE connector.
Baseboard Description 19
USB Interface
The SKA4 baseboard provides a dual external USB connector for the back panel of a server
system. The connector is defined by the USB Specification, Revision 1.0. Both ports function
identically with the same bandwidth. The SKA4 baseboard also provides a proprietary internal
USB header.
Network Interface Controller (NIC)
The SKA4 baseboard supports a 10BASE-T/100BASE-TX network subsystem based on the
®
82559 Fast Ethernet Multifunction PCI/CARDBus controller. The Intel 82559 controller is
Intel
a highly integrated PCI LAN controller in a 196-pin Ball Grid Array (BGA) supporting 10 or

• 82596-like chained memory structure with improved dynamic transmit chaining for enhanced
performance
• Programmable transmit threshold for improved bus utilization
• Early receive interrupt for concurrent processing of receive data
• On-chip counters for network management
• Auto-detect and auto-switching for 10 or 100 Mbps network speeds
• Support for both 10 and 100 Mbps networks
• Integrated physical interface to TX magnetics
• The magnetics component terminates the 100BASE-TX connector interface and a flash device
stores the network ID
Video
The SKA4 baseboard provides an ATI Rage IIc VGA Graphics Accelerator, along with video
Synchronous Graphics RAM (SGRAM) and support circuitry for an embedded Super VGA
(SVGA) video subsystem. The ATI Rage IIc chip contains an SVGA video controller, clock
generator, BitBLT engine, and a RAM digital-to-analog Converter (RAMDAC) in a 208-pin
PQFP. One 256K x 32 SGRAM chip provides 2 MB of 10-ns video memory. The baseboard does
not support adding video memory to the system. The SVGA subsystem supports a variety of
modes, up to 1600 x 1200 resolution, or up to 16.7 M colors.
The SVGA subsystem also supports analog VGA monitors, single- and multi-frequency, interlaced
and non-interlaced, up to 100 Hz vertical retrace frequency. The SKA4 baseboard provides a
standard 15-pin VGA connector and video blanking logic for server management console
redirection support.
Depending on the environment, the controller displays up to 16.7 M colors in some video
resolutions.
20 SKA4 Baseboard Product Guide
SCSI Controller
The baseboard includes two SCSI controllers. A dual function SCSI controller
(Adaptec AIC-7899) is on the PCI-B bus, and a PCI wide SCSI controller (Adaptec AIC-7880) is
on the PCI-C bus.
The Adaptec AIC-7899 SCSI controller contains two independent SCSI controllers that share a
single PCI bus master interface as a multifunction device, packaged in a 352-pin ball grid array
(BGA). Internally, each controller is identical, capable of operations using either 16-bit SE or Low
Voltage Differential (LVD) SCSI providing 40 MBps (Ultra-wide SE), 80 MBps (Ultra 2), or
160 MBps (Ultra 160/m).
In the SKA4 implementation, both controller A and controller B attach to a 68-pin 16-bit
differential SCSI connector LVD interface. Each controller has its own set of PCI configuration
registers and SCSI I/O registers. As a PCI bus master, the AIC-7899 controller supports burst data
transfers on PCI up to the maximum rate of 266 MBps using on-chip buffers.
The AIC-7880 controller contains a single SCSI controller with full-featured PCI bus master
interface in a 160-pin Plastic Quad Flat Pack (PQFP). The controller supports either 8- or 16-bit
Fast SCSI providing 10 MBps or 20 MBps (Fast-10) throughput, or Fast-20 SCSI that can burst
data at 20 MBps or 40 MBps. As a PCI 2.1 bus master, the AIC-7880 controller supports burst
data transfers on PCI up to the maximum rate of 133 MBps using the on-chip 256-byte FIFO.
The SKA4 AIC-7880 implementation offers 8-bit or 16-bit SCSI connectors and operation at data
transfer rates of 10, 20, or 40 MBps. The AIC-7880 controller also offers active negation outputs,
controls for external differential transceivers, a disk activity output, and a SCSI terminator powerdown control. Active negation outputs reduce the chance of data errors by actively driving both
polarities of the SCSI bus, avoiding indeterminate voltage levels and common-mode noise on long
cable runs. The SCSI output drivers can directly drive a 48-mA single-ended SCSI bus with no
additional drivers. The SCSI segment can support up to 15 devices.
The AIC-7880 controller can be used as an 8-bit controller via the narrow, 50-pin connector and as
a 16-bit controller via the wide, 68-pin connector. As a result, the AIC-7880 controller is not
always at one end of the SCSI bus, and termination is controlled through some simple circuitry.
The circuitry senses whether there is a device attached through the narrow 50-pin connector or the
wide 68-pin connector. When there are devices off both connectors, the termination is on for the
upper 8 bits of data and the parity bit associated with these data lines. All other signals are not
terminated on board and are terminated by the devices attached through the connector. When there
is a device on only one connector (either wide or narrow), all on-board termination is on.
Baseboard Description 21
IDE Controller
IDE is a 16-bit interface for intelligent disk drives with AT† disk controller electronics onboard.
The Open South Bridge (OSB4) acts as a PCI-based fast IDE controller. The device controls:
• PIO and IDE DMA/bus master operations
• Mode 4 timings
• Transfer rates up to 33 MB/sec
• Ultra DMA 33 capacity
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
• Up to two drives for one IDE channel
NOTE
✏
18-inch maximum length of IDE cable: An IDE signal cable can be
connected up to the IDE connector on the baseboard. However, the
maximum length of the cable is 18 inches. The cable supports up to two
devices, one at the end of the cable and the other six inches from the end.
Keyboard and Mouse
The PS/2-compatible keyboard and mouse connectors are mounted in a single-stacked housing
with the mouse connector over the keyboard. External to the system, they appear as two
connectors.
The user can plug in the keyboard and mouse to either connector before powering up the system.
BIOS detects these and configures the keyboard controller accordingly.
®
The keyboard controller is functionally compatible with the Intel
system can be locked automatically if no keyboard or mouse activity occurs for a predefined length
of time, if specified through the SSU. Once the inactivity (lockout) timer has expired, the
keyboard and mouse do not respond until the previously stored password is entered.
8042A microcontroller. The
22 SKA4 Baseboard Product Guide
Server Management
Server management features are implemented using one microcontroller called the Baseboard
Management Controller (BMC).
Baseboard Management Controller (BMC)
The BMC and associated circuitry are powered from 5V_Standby, which remains active when
system power is switched off. The BMC is IPMI 1.0 compliant.
The primary function of the BMC is to autonomously monitor system platform management events
and log their occurrence in the nonvolatile System Event Log (SEL). The BMC is compliant to the
Intelligent Platform Management Interface Specification, Version 1.0. These events include
overtemperature and overvoltage conditions, fan failure, or chassis intrusion. While monitoring,
the BMC maintains the nonvolatile Sensor Data Record Repository (SDRR), from which run-time
information can be retrieved. The BMC provides an interface to SDRR information, so software
running on the server can poll and retrieve the current status of the platform. A shared register
interface is defined for this purpose.
Field service personnel can retrieve SEL contents after system failure for analysis by using system
®
management tools like Intel
Platform control (DPC). Because 5V_Standby provides power the BMC, SEL (and SDRR)
information is also available via the interperipheral management bus (IPMB). During monitoring,
the BMC performs the following functions:
• Baseboard temperature and voltage monitoring
• Processor presence monitoring and FRB control
• Baseboard fan failure detection and indicator control
• SEL interface management
• Sensor Data Record Repository (SDRR) interface management
• SDR/SEL timestamp clock
• Baseboard Field Replaceable Unit (FRU) information interface
• System management watchdog timer
• SMI/NMI Status Monitor
• Front panel NMI handling
• Event receiver
• IPMB Management Controller Initialization Agent
• Secure mode control, front panel lock/unlock initiation, and video blank and diskette write
protect monitoring and control
• ACPI Support
• Direct Platform Control (DPC) support
• Platform Event Paging (PEP) / Platform Event Filtering (PEF)
• Power distribution board monitoring
• Speaker beep capability. When the system is powered up, this capability is used to indicate
conditions such as "empty processor slot"
• Pentium III Xeon processor SEEPROM interface for Processor Information ROM (PIROM)
and Scratch EEPROM access

• Processor temperature monitoring
• Hot-Plug PCI slot status reporting

System Security
To help prevent unauthorized entry or use of the system, the system includes a three-position key
lock/switch to permit selected access to drive bays (position is communicated to BMC). The
system also includes server management software that monitors the chassis intrusion switch.
Software Locks via the SSU or BIOS Setup
The SSU provides a number of security features to prevent unauthorized or accidental access to the
system. Once the security measures are enabled, access to the system is allowed only after the user
enters the correct password(s). For example, the SSU allows:
• Enable the keyboard lockout timer so the server requires a password to reactivate the keyboard
and mouse after a specified time-out period of 1 to 120 minutes
• Set and enable administrator and user passwords
• Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset
and power switches
• Activate a hot key combination to enter secure mode quickly
• Disable writing to the diskette drive when secure mode is set
Using Passwords
If a user password is set and enabled, but an administrator password is not set, a user password
must be entered to boot the system and run the SSU.
If both a user and administrator password is set:
• Enter either one to boot the server and enable the keyboard and mouse
• Enter the administrator password to access the SSU or BIOS Setup to change the system
configuration
Secure Mode
Configure and enable the secure boot mode by using the SSU. When secure mode is in effect,
• The system can boot and the operating system runs, but the user password must be entered for
a user to use the keyboard or mouse
• The system cannot be turned off or reset from the front panel switches
Secure mode has no effect on functions enabled via the Server Manager Module or power control
via the real-time clock (RTC).
24 SKA4 Baseboard Product Guide
Taking the system out of secure mode does not change the state of system power. That is, if you
press and release the power switch while secure mode is in effect, the system will not power off
when secure mode is later removed. However, if the front panel power switch remains depressed
when secure mode is removed, the system will power off.
Summary of Software Security Features
Table 4 lists the software security features and describes what protection each offers. In general,
to enable or set the features listed here, the SSU must be run and configured with the Security
Menu (described in this manual on page 39.) The table also refers to other SSU menus and to the
Setup utility. For greater detail, see Chapter 2, beginning on page 27.

How to enter secure mode:
• Setting and enabling passwords automatically places the system in secure
mode.
• If a hot key combination is set (through the SSU or Setup), the system can be
secured simply by pressing the key combination. This means that the user
does not have to wait for the inactivity time-out period.
When the system is in secure mode:
• The server can boot and run the operating system, but mouse and keyboard
input is not accepted until the user password is entered.
• At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A,
the system prompts for a password. When the password is entered, the
server boots from CD or diskette and disables the secure mode.
• If there is no CD in the CD-ROM drive or diskette in drive A, the server boots
from drive C and automatically goes into secure mode. All enabled secure
mode features go into effect at boot time.
To leave secure mode, enter the correct password(s).

To write protect access to diskette whether the server is in secure mode or not,
use the Setup main menu, Floppy Options, and specify Floppy Access as
read only.
Power and reset buttons are always disabled when the server is in secure mode.
Specify and enable an inactivity time out period of from 1 to 120 minutes.
If no keyboard or mouse action occurs for the specified period, attempted
keyboard and mouse input will not be accepted.
The monitor display will go blank, and the diskette drive will be write protected
(if these security features are enabled through Setup or the SSU and using
onboard video).
To resume activity, enter the user password.

Power-On Self Test (POST)
Each time you turn on the system, the BIOS begins execution of the Power-On Self Test (POST).
POST discovers, configures, and tests the processors, memory, keyboard, and most installed
peripheral devices. The length of time needed to test memory depends on the amount of memory
installed. POST is stored in flash memory.
1. Turn on your video monitor and system. After a few seconds, POST begins to run and a splash
screen is displayed.
2. While the splash screen is displayed, you can either
• press <F2> to enter the BIOS Setup (see "Using BIOS Setup" on page 29)
OR
• press <Esc> to change the boot device priority for this boot only (see "Changing the Boot

Using BIOS Setup
This section describes the BIOS Setup options. Use Setup to change the system configuration
defaults. You can run Setup with or without an operating system being present. Setup stores most
of the configuration values in battery-backed CMOS; the rest of the values are stored in flash
memory. The values take effect when the system is booted. POST uses these values to configure
the hardware; if the values and the actual hardware do not agree, POST generates an error
message. You must run Setup to specify the correct configuration.

If the default values ever need to be restored (after a CMOS clear, for example), Setup must be run
again. Referring to the worksheets could make the task easier.
If Setup is Not Accessible
If the diskette drive is misconfigured and you cannot use Setup to correct the problem, you might
need to clear CMOS memory. You must open the system, change a jumper setting, use Setup to
check and set diskette drive options, and change the jumper back. For a step-by-step procedure,
see “CMOS Clear Jumper” on page 109.
Starting Setup
Setup can be entered under several conditions:
• When you turn on the system, after POST completes the memory test.
• When you reboot the system by pressing <Ctrl+Alt+Del> while at the DOS operating system

After pressing <F2> or <Esc> during POST, the splash screen is replaced by text.
The system first finds the Adaptec AIC-7880 SCSI host adapter and displays the message
Adaptec AIC-7880 SCSI BIOS V x.xxx where x.xxx is the version number of the SCSISelect
utility. Pressing <Ctrl+A> at this time allows you to configure the Adaptec AIC-7880 SCSI host
adapter.
If you do not press <Ctrl+A>, the system finds the Adaptec AIC-7899 SCSI host adapter and
displays the message
of the SCSISelect utility. Pressing <Ctrl+A> at this time allows you to configure the Adaptec
AIC-7899 SCSI host adapter.
Once you enter the configuration menus for one of the host adapters, you cannot switch to the
other adapter. For example, once you press <Ctrl+A> to configure the Adaptec AIC-7899 SCSI
host adapter, you have to reboot the system to configure the Adaptec AIC-7880 SCSI host adapter.

Using the System Setup Utility (SSU)
The SSU is on the configuration software CD shipped with the server. The SSU provides a
graphical user interface (GUI) over an extensible framework for server configuration. The
SSU framework supports the following functions and capabilities:
• Assigns resources to baseboard devices and add-in boards before loading the operating system
• Specifies the boot device order and system security options
• Permits viewing and clearing of the system event log (SEL)
• Permits viewing of the system FRU and SDRs
• Allows troubleshooting of the server when the operating system is not operational
• Provides a system-level view of the server’s I/O devices
When to Run the SSU
The SSU is a DOS-based utility that supports extended system configuration operations for
onboard resources and add-in boards. Use the SSU to:
• Add and remove boards affecting the assignment of resources (ports, memory, IRQs, DMA)
• Modify the server’s boot device order or security settings
• Change the server configuration settings
• Save the server configuration
• View or clear the SEL
• View FRU information
• View the SDR table
The SSU is PCI 2.1 compliant and uses the information entered and provided by configuration
registers, flash memory to specify a system configuration. The SSU then writes the configuration
information to flash memory.
The SSU stores configuration values in flash memory. These values take effect when the server is
booted. POST checks the values against the actual hardware configuration; if the values do not
agree, POST generates an error message. You must then run the SSU to specify the correct
configuration before the server boots.
The SSU always includes a checksum with the configuration data so the BIOS can detect any
potential data corruption before the actual hardware configuration takes place.
Configuration Software and Utilities 47
What You Need to Do
Run the SSU directly from the configuration software CD after you have installed a CD-ROM
drive, or from a set of diskettes.
If you choose to run the SSU from diskettes, create the SSU diskettes from the CD by following
the instructions in "Creating SSU Diskettes" on page 48.
If the diskette drive is disabled or improperly configured, use the flash-resident Setup utility to
enable it to use the SSU. If necessary, disable the drive after exiting the SSU. Information entered
using the SSU overrides any entered using Setup.
Running the SSU Remotely
Running the SSU remotely requires a remote server with a LANDesk Server Monitor Module 2
(SMM2) card and a local system with Remote Control software available.
When running the SSU remotely, the client SSU (CSSU) runs on the remote server. The CSSU
controls the local server and uses the local server’s SSU software.
The SMM2 card provides video memory, keyboard, and mouse redirection support for the remote
server. The Remote Control console of the local system displays and sends video memory and
user input to the remote server through either a modem or an Ethernet link. Because the CSSU
runs exclusively on the remote server, any files required for the CSSU to run must be available on
the remote server (on removable or non-removable media).
If the local system is connected to the remote server through a network or modem, you can see the
console of the local system, control the mouse, and control the keyboard from the remote server.

48 SKA4 Baseboard Product Guide
Running the SSU
You can run the SSU from diskettes, a hard drive, or a CD-ROM drive.
Running the SSU from Diskettes
For best results, Intel recommends that you execute the SSU from diskettes. Place the bootable
diskette in the floppy drive. Typically, the floppy drive is recognized by the system as drive A. If
the system is not set to boot from the floppy drive, change the boot priority. For more information,
see "Changing the Boot Device Priority Permanently" on page 44. After making sure that the
system boots from the floppy drive, restart the system.
Once the system boots, a virtual drive is created. The System Setup Utility files are copied to the
virtual drive and invoked.
Running the SSU from a CD
You can also run the SSU from a CD. Place the CD in the CD-ROM drive. If the system is not set
to boot from the CD-ROM drive, change the boot priority. For more information, see "Changing
the Boot Device Priority Permanently" on page 44. After making sure that the system boots from
the CD-ROM drive, restart the system. Run the file SSU.BAT.
Running the SSU from a Hard Drive
First, install the SSU software to the hard drive. To install the SSU software on the hard drive,
insert either the diskette or CD into the floppy drive or CD-ROM drive respectively. Run the
excitable file called SSIOMAGE.EXE. If you are using diskettes, the executable file is on disk 1.
When prompted, insert disk 2.
Lastly, run the file SSU.BAT on the hard disk. Note that the SSU does not function properly in a
DOS window under another operating system.
Direct Platform Control (DPC) Console
Direct Platform Control (DPC) Console is an application that provides a user interface to the
emergency management port (EMP). The EMP allows remote system management.
DPC console runs on a client workstation. It communicates with a server by
• A Windows† 98/NT compatible modem.
• An RS-232 connection to the server COM2 port.
DPC Console is independent of the server operating system.
Even when the server is powered off, you can use DPC Console to verify the state of a server or
diagnose a problem with the server hardware. DPC console features allows you to:
• Establish or end a connection to a remote server.
• Apply power to a remote server.
• Remove power from a remote server.
• Reset a remote server to either EMP mode or Re-direct Mode.
Configuration Software and Utilities 49
• Retrieve and display:
System Event Log (SEL) entries for information about recent server activities, such as
from processors or fans.
Sensor Data Records (SDR) entries for information about sensor characteristics.
Field Replaceable Unit (FRU) inventories of the hardware components on the server.
Current Remote Sensor Access (RSA) information.
• Maintain a Phonebook for remote connection management.
• Run Remote Diagnostics.
• Transfer file to and from a server.
• Reboot to the service partition to get access to run DOS-based utilities on the server.
DPC Console Modes of Opera tion
There are three modes DPC console modes of operation:
• EMP mode. The default mode. DPC console features are accessed using the DPC console
window menus and/or toolbar.
• Re-direct mode. Active when the server is running BIOS console redirection. In this mode,
the DPC console launches a separate window. The window operates as an ANSI terminal and
communicates with the server through the port. Character-based commands you type in the
DPC Console are sent directly to the server, and the DPC Console displays the text that would
normally be displayed on the server console.
To use this mode, you must configure the Console Redirection option of BIOS setup for Redirect mode. If the redirection window does not display information, the Console Redirection
is not correctly configured or enabled, the EMP is disabled in BIOS setup, or the server is in
protected mode. For DPC to function, the server must NOT be in graphics mode.
If the DPC console fails to connect in EMP within 10 seconds and the server can operate in
Re-direct mode, a prompt is displayed with the option to switch to Re-direct mode.
• Service Partition mode. Entered when the server reboots from the service partition and the
DPC Console has successfully connected to the server through a modem. This mode allows
running of DOS-based programs that are stored on the service partition and transferring of
files.
Running the DPC Console
For more information about setting up and running the DPC Console, see the document named
"ENUDPCUG.pdf". This document is in the Manuals\SrvMgmt directory on the server software
kit accompanying the SKA4 baseboard.

FRU and SDR Load Utility
The Field Replacement Unit (FRU) and Sensor Data Record (SDR) load utility is a DOS-based
program used to update the server management subsystem’s product level FRU, SDR, and the
Desktop Management Interface (DMI) nonvolatile storage components (EEPROMs). The utility:
• Discovers the product configuration based on instructions in a master configuration file
• Displays the FRU information
• Updates the EEPROM associated with the Baseboard Management Controller (BMC) that
holds the SDR and FRU area
• Updates the DMI FRU area located in the BIOS nonvolatile storage device
• Generically handles FRU devices that might not be associated with the BMC
What You Need to Do
Run the utility either directly from the configuration software CD or from diskettes created from
the CD.
If you run the FRUSDR Load Utility from a diskette, copy the utility from the CD. Follow the
instructions in the included README.TXT file.
If the diskette drive is disabled, or improperly configured, use BIOS Setup to enable it. If
necessary, disable the drive after you are done with the FRUSDR utility.
How You Use the FRUSDR Load Utility
The utility:
• Is compatible with ROM-DOS Ver. 6.22, MS-DOS Ver. 6.22, and later versions
• Accepts CFG, SDR, and FRU load files (the executable file for the utility is frusdr.exe)
• Requires the following supporting files
one or more .fru files describing the system’s field replaceable units
a .cfg file describing the system configuration
an .sdr file describing the sensors in the system
Command Line Format
The basic command line format is
frusdr [-?] [-h] [-d {dmi, fru, sdr}] [-cfg filename.cfg] [-fru filename.fru]
Table 43. Command Line Format
Command Description
-? or -h Displays usage information
-d {dmi, fru, sdr} Displays requested area only
-cfg filename.cfg Uses custom CFG file
-p Pause between blocks of dat a
Configuration Software and Utilities 51
Parsing the Command Line
The FRUSDR load utility allows only one command line function at a time. A command line
function can consist of two parameters. Example: -cfg filename.cfg. Invalid parameters cause an
error message and exit the program. You can use either a slash (/) or a minus sign (-) to specify
command line options. The -p and flags can be used in conjunction with any of the other options.
Displaying a Given Area
When the utility is run with the -d DMI, -d FRU, or -d SDR command line flag, information about
each area is read from memory and printed on the screen. Each area represents one sensor for each
instrumented device in the server. If the given display function fails because of an inability to
parse the data present or a hardware failure, the utility displays an error message and exits.
Using Specified CFG File
The utility can be run with the command line parameter of -cfg filename.cfg. The filename can be
any DOS-accepted, eight-character filename string. The utility loads the specified CFG file and
uses the entries in that file to probe the hardware and to select the proper SDRs to load into
nonvolatile storage.
Displaying Utility Title and Version
The utility displays its title
:
FRU & SDR Load Utility, Version Y.Y, Revision X.XX where Y.Y is the version number and
X.XX is the revision number for the utility.
Configuration File
The configuration file is in ASCII text. The utility executes commands formed by the strings
present in the configuration file. These commands cause the utility to run tasks needed to load the
proper SDRs into the nonvolatile storage of the BMC and possibly generic FRU devices. Some of
the commands may be interactive and require you to make a choice.
Prompting for Product Level FRU Information
Through the use of a configuration file, the utility might prompt you for FRU information.
Filtering Records From the SDR File
The MASTER.SDR file has all the possible SDRs for the system. These records might need to be
filtered based on the current product configuration. The configuration file directs the filtering of
the SDRs.
Updating the SDR Nonvolatile Storage Area
After the utility validates the header area of the supplied SDR file, it updates the SDR repository
area. Before programming, the utility clears the SDR repository area. The utility filters all tagged
SDRs depending on the product configuration set in the configuration file. Nontagged SDRs are
automatically programmed. The utility also copies all written SDRs to the SDR.TMP file; it
contains an image of what was loaded. The TMP file is also useful for debugging the server.
52 SKA4 Baseboard Product Guide
Updating FRU Nonvolatile Storage Area
After the configuration is determined, the utility updates the FRU nonvolatile storage area. First it
verifies the common header area and checksum from the specified FRU file. The internal use area
is read out of the specified .FRU file and is programmed into the nonvolatile storage. The chassis
area is read out of the specified .FRU file. Finally, it reads the product area out of the specified
FRU file, then the area is programmed into the FRU nonvolatile storage. All areas are also written
to the FRU.TMP file.
Updating DMI FRU Nonvolatil e St orage Area
After programming the BMC FRU area, the utility programs chassis, board, and product
FRU information to the DMI fields, if the DMI flag follows each FRUAREA command in the
configuration file.
Cleaning Up and Exiting
If an update was successfully performed, the utility displays a single message and then exits.
If the utility fails, it immediately exits with an error message and exit code.

Safety: Before You Work with the Baseboard
Before working with the baseboard, provide some electrostatic discharge (ESD) protection by
wearing an antistatic wrist strap attached to chassis ground of the system—any unpainted metal
surface. Turn off the system by using the power on/off switch on the front panel AND unplug all
AC power cords.
✏ NOTE
Hot-Plug PCI add-in boards: If you are only removing and/or installing
Hot-Plug PCI add-in board, you do not need to turn off the system.
Warnings and Cautions
These warnings and cautions apply whenever you work with the SKA4 baseboard. Only a
technically qualified person should integrate and configure the system.
✏ NOTE
Hot-Plug PCI add-in boards: If you are only removing and/or installing
Hot-Plug PCI add-in boards, you do not need to turn off the system and the
warnings pertaining to turning off the system do not apply.
59
WARNINGS
System power on/off: The on/off button (a convex button) on the
front panel DOES NOT turn off the system AC power. To remove
power from system, you must unplug the AC power cords from the wall
outlet or the system.
Hazardous conditions, devices, and cables: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn off the system and disconnect the power cords,
telecommunications systems, networks, and modems attached to the
system before opening it. Otherwise, personal injury or equipment
damage can result.
CAUTIONS
Electrostatic discharge (ESD) and ESD protect i on: ESD can
damage disk drives, boards, and other parts. We recommend that you do all
procedures in this chapter only at an ESD-protected workstation. If one is
not available, provide some ESD protection by wearing an antistatic wrist
strap attached to chassis groundany unpainted metal surfaceon your
system when handling parts.
ESD and handling boards: Always handle boards carefully. They can
be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the system, place it
component-side UP on a grounded, static-free surface. If you place the
baseboard on a conductive surface, the battery leads may short out. If they
do, this will result in a loss of CMOS data and will drain the battery. Use a
conductive foam pad if available but NOT the board wrapper. Do not slide
board over any surface.
Chassis covers, proper cooling, and airflow : For proper cooling and
airflow, always install the chassis access covers before turning on the
system. Operating the system without this cover in place can damage
system parts.
Installing or removing jumpers: A jumper is a small, plastic-encased
conductor that slips over two jumper pins. Newer jumpers have a small tab
on top that you can grip with your fingertips or with a pair of fine, needlenosed pliers. If your jumpers do not have such a tab, take care when using
needle-nosed pliers to remove or install a jumper; grip the narrow sides of
the jumper with the pliers, never the wide sides. Gripping the wide sides can
damage the contacts inside the jumper, causing intermittent problems with
the function controlled by that jumper. Take care to gently grip, but not
squeeze, with the pliers or other tool you use to remove a jumper; you might
bend or break the stake pins on the board.
60 SKA4 Baseboard Product Guide
Memory
Memory amounts from 256 MB to 16 GB of DIMM are supported, with a 64/72-bit
four-way-interleaved pathway to main memory, which is also located on the module. Therefore,
data transfers between MADPs and DIMMs is in four-way interleave fashion. Each of the four
DIMMs must be populated in a bank. The 16 slots are divided into four banks of four slots each.
They are labeled A through D. Bank A contains DIMM sockets A1, A2, A3, and A4. Banks B, C,
and D each contain 4 DIMM sockets and are named in the same fashion. There are silk screens on
the module next to each DIMM socket to label its bank number. DIMM banks do not have to be
filled in any order, but for best thermal results, you should populate them from A to D. If only one
DIMM bank is used, use bank A first, and then B, C, and D.

representative.
ESD and handling processors: Reduce the risk of electrostatic
discharge (ESD) damage to the VRM by doing the following: (1) Touch the
metal chassis before touching the VRM or baseboard. Keep part of your
body in contact with the metal chassis to dissipate the static charge while
handling the VRM. (2) Avoid moving around unnecessarily.
To decide what VRM you need to remove, see Figure 1 on page 14.
1. Using a small flat-bladed screwdriver, push the plastic ejector levers on each end of the
connector away from the VRM to eject it out of the connector.
2. Pull VRM straight up and out of the baseboard.
3. Place the VRM on a nonconductive, static-free surface, or store it in an antistatic protective
wrapper.
Installing a VRM
To decide what VRM you need to install, see Figure 1 on page 14.
1. Remove the VRM from its protective package.
2. Orient the VRM within the VRM connector correctly. See Figure 6 on page 67.
3. Carefully insert the VRM in the connector on the baseboard. Make sure you do not bend the
connector pins.
4. Push down firmly on both ends of the VRM until the ejector levers of the connector snap into
place, locking the VRM in the connector.

ICMB Card
The ICMB card allows two servers to communicate through a serial connection. An ICMB card is
installed in each server; the cards are connected through a serial cable.
Establishing communication between servers using the ICMB card is a two-step process. First,
install the ICMB card in each server. Lastly, make sure that the software required for the card is in
place. Software for the ICMB card includes firmware on the card and software already included in
the ISC software. ISC software is included in the server software kit accompanying the SKA4
baseboard.
This product guide does not discuss the software for the ICMB card. However, this product guide
does provide instructions for removing and installing ICMB hardware.

4 Solving Problems
This chapter helps you identify and solve problems that might occur while you are using the
system.
In the event you encounter an issue with your SKA4 baseboard, this chapter helps you trouble
shoot and identify possible problem areas. In some cases, you are directed to contact your
customer service representative.
Boot Issues
Issue 1: My server will not power on
Check for the following possibilities:
• Is the server AC power cord securely plugged into the power supply?
• Is the server plugged into a “powered on” power strip?
• Some ATX power supplies have a power switch on the back of the power supply next to the
fan, is it switched on?
• Is the front panel power switch cable properly connected to the front panel header pins on the
baseboard located at J9E3, pins 2 and 16?
• If you are using a SSI compliant power supply, make sure the proper power supply connector
is attached to the auxiliary signal connector. SSI power supplies require a 3-volt sense signal
to properly power on and have a special 5 pin by 2 row connector for that purpose. If that
connector is available with your power supply, make sure it is firmly seated in the Auxiliary
Signal connector located at J9B2 on the baseboard.
• Remove all add-in cards and see if the server boots using just the on-board components. If
successful, add the cards back in one at a time with a reboot in between to see if you can
pinpoint a suspect card.
• Remove the processor and terminator card and reseat them.
• Remove and reseat the memory modules. Try using memory modules from a known working
server system. Memory must be used in fours.
Though it is unlikely that a server will not boot, there are many reasons why it may not boot. If
you are unable to resolve this issue, please fill out the included customer support form and call
your customer support representative. Please note the answers to the following questions below.
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
• What chassis and power supply is being used?
• If you are using a chassis with front panel lights, are there any front panel lights on?
• Is the power supply fan spinning?
• Does the system beep? See issue 2.
• Please note what is displayed on the monitor or any sounds emanating from the server system.
77
Issue 2: Upon boot, my ser ver starts bee ping
Most likely, these beeps are what are known as “beep codes.” They identify system events in case
video fails to display. The following list is an excerpt of available beep codes. Contact your
customer service representative for a complete list of beep codes.
Table 46. Standard BIOS Port-80 Codes
CP Beeps Reason
xx 1-1-1-1 There are no processors present in the system, or the processor s are so
incompatible that the system BIOS cannot be run (like mismatched cache
voltages).

Issue 3: My HDD lights went on, I heard the drives spin up, and
my floppy drive light turned on – but I’m not seeing
video
Check the following:
• Remove all add-in cards and retry booting with just the on-board components. If successful,
try adding the add-in boards one at a time with a reboot in between to try and pinpoint a
suspect card.
• Remove and reseat memory modules. Try using memory from a known working system.
• Remove and reseat processor and terminator card.
• If you are using a switch box to share a monitor between multiple servers, ensure you are
switched to the proper server.
78 SKA4 Baseboard Product Guide
If you are still unable to get a video image, please fill out the included customer support form and
call your customer support representative. Please note the answers to the following questions
below.
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
• What chassis and power supply is being used?
• If the chassis has front panel lights, are there any front panel lights on?
• Is the power supply fan spinning?
• Does the system beep? See issue 2.
• Please note any sounds emanating from the server system.
• If you are using a third party video adapter, please have manufacturer and model number
ready.
Issue 4: I’m installing adapters in my powered-down system, and
my system boots up when I install a PCI adapter!
Server management features require full time “standby” power. This means that power is still
provided to parts of the system even if the user has turned the system “off” via the front panel
power switch.
Additionally, there are signals in the PCI connectors that tell the system to boot (normally used by
server management adapters/NICs). Plugging in the adapter with AC power still applied can cause
false signals to be transmitted commanding the system to boot. Before removing the cover to your
chassis, you should always
• Turn off the server via the front panel power switch.
• Unplug the AC cord from the back.
Also, see issue 5. If your server is booting automatically, but the conditions specified here or in
issue 5 do not match, please fill out the included customer support form and call your customer
service representative. Please pay special attention to the following information:
• What BIOS do you have loaded on the system? (The latest tested BIOS is posted to the Intel
Customer Support Website)
• What is the PBA number of the baseboard? (The PBA number is located on a white label near
the edge of the board and is printed in the following format: PBA xxxxxx-xxx)
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
• What chassis and power supply is being used?
Solving Problems 79
Issue 5: My system boots up automatically when I power on my
power-strip
Some server systems save the “last known power state” since the last AC power connection. If
you remove AC power before powering down the system via the front panel power switch, your
system will automatically attempt to come back to the “on” state it was in once you restore AC
power.
• Please keep in mind that unplugging the system or flipping a switch on the power strip both
remove AC power.
• Follow the correct A/C removal sequence: Press the front panel button, then remove the A/C
power cord.
Allowing your system to fully power up and then power down the system using the front panel
power switch should correct this problem. If it does not, refer to issue 3. If neither of these
options fix your problem, fill out the attached customer support form and call your customer
support representative. Please have the following information available:
• What BIOS do you have loaded on the system? (the latest tested BIOS is posted to the Intel
Customer Support Website)
• What is the PBA number of the baseboard? (The PBA number is located on a white label near
the edge of the board and is printed in the following format: PBA xxxxxx-xxx)
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
• What chassis and power supply is being used?
Issue 6: The boot up process takes too long
What most people typically consider “booting” actually involves multiple phases:
• BIOS Power-On Self Test (POST): This includes the memory count and the keyboard/mouse
and IDE drive check.
• Option-ROM loading: Each device may load a portion of its operating code or “option ROM”
into memory. This is what the user may see as the messages that come up identifying the
add-in device such as a SCSI card ROM.
• Operating system boot: During this time, the operating system takes control of the server and
performs whatever checks & setups are necessary for operation. An example of this is the
Windows NT “blue boot screen.”
A slow-down at any of these three points can produce what users perceive as a “slow boot.” The
following is a list of items that can produce a slower boot:
• Large memory configurations. Large memory installations can take 1-2 minutes to check.
Extended memory test can be disabled in BIOS setup to speed up the boot process when
performing service which requires multiple reboots, however this memory test should be
enabled for normal system operation.
• Multiple SCSI adapters. SCSI adapters take time to load their option ROMs and execute their
code that scans for drives.
80 SKA4 Baseboard Product Guide
• Numerous SCSI devices. SCSI device adapters, like many other adapters, have option ROMs
that must be loaded into memory. Detection & option ROM loading takes additional time.
• Numerous other adapters. Many adapters have a option ROM which takes time to load into
memory.
If your system does not have any of these items and you still experience an extended boot time,
please fill out the included customer support form and call your customer support representative.
Please pay special attention to the following information:
• Amount of memory in the system.
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
• Number and type of adapters in the system (manufacturer and model number).
• The number and type of hard drives in the system (manufacturer and model number).
Issue 7: I put one processor in my system but it doesn’t boot
Check the following:
• Is the processor a 100 MHz system bus or 133 MHz system bus processor? The SKA4 server
board only supports Intel Pentium III processors designed for the100 MHz system bus.
• Is the processor in the primary processor slot? Refer to the configuration label or the
Technical Product Specification for details on which slot is the primary.
• Does the secondary processor slot contain a terminator card? The Pentium III processor
architecture requires non-populated processor slots to be terminated. Without proper
termination, the signals do not maintain their electrical integrity & may cause errors. Some
server products prevent boot up if they do not detect a terminator card.
• Are the processor and terminator card firmly seated? The retention mechanisms designed to
hold the processor and term card firmly in place. Ensure the processor and termination card
have “snapped” into the retention mechanism.
• Does the system beep? Refer to issue 2.
If you are still having no-boot issues, please fill out the included customer support form and call
your customer support representative. Have the following information ready:
• Does the system beep? What beep code is it giving?
• Does the system show video?
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
• What error does the system give if any?
• What add-in adapters are installed in your system? (manufacturer and model number)
• Chassis and power supply manufacturer and model number.
Solving Problems 81
Other Issues
Issue 8: Some of my hard drives show up during POST and
some don’t
Check on the following:
• Are you using third party SCSI adapters? System memory limitations limit the number & size
of option ROMs in the system. If you place too many adapters or adapters that take up too
much space in memory, they may not install and show the hard drives connected to them.
• If you disconnect your hard drives from the third party adapter and connect them to the on-
board adapter, do they show up?
• Verify that pin 1 on the data cable is connected to pin 1 on the device. In most cases, if you
orient the data cable so that the colored stripe on the cable is pointing towards the power
connector on the device, you will have proper orientation.
• Verify that the device power cable is firmly connected.
• Are your hard drives properly terminated? If you are using Ultra 2 or Ultra 160 drives without
a hot-swap backplane, a terminator needs to be placed in the last connector on the SCSI cable.
Ultra 2/Ultra 160 devices do not provide their own termination logic like Ultra Wide devices
did.
• Check your SCSI ID numbers. SCSI devices must have their own unique ID on the SCSI bus.
This number is set automatically when using an Intel SCSI hot-swap backplane, but must be
set with jumpers on the device when using a SCSI cable. ID number should be set starting at 0
and must be set lower than 8 if the drive is to be booted from.
If your hard drives still do not show, please fill out the included customer support form and call
your customer support representative. Please pay special attention to the following information:
• What add-in adapters do you have in your system (manufacturer and model number)?
• What types of hard drives are in the system (manufacturer and model number)?
• If you are using a SCSI cable to attach your drives, what kind of terminator do you have at the
end of the cable? (manufacturer and type e.g. ultra 160)
• What are the SCSI IDs of the devices on your SCSI bus?
• How many SCSI channels are you using?
• Are you using a hot-swap backplane with your third party adapter?
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.
82 SKA4 Baseboard Product Guide
Issue 9: My hard drives don’t show up under Windows NT
Verify that all your drives are detected during POST (see issue 8). IDE devices will be identified
and listed on the screen by the server board BIOS and SCSI drives will be identified and listed on
the screen by the SCSI BIOS.
Windows NT 4.0 does not ship with the latest drivers for some SCSI controllers. Because of this,
Windows NT installation must be directed to the proper drivers during installation. To do this, you
must press the F6 key during installation start up at the sight of the first “installation blue screen.”
This will allow you to skip auto-detection and manually install a driver. The other way to perform
a manual install is to use the three boot floppies. When asked to perform an auto detection of mass
storage devices or do it manually, choose to do it manually and you will be asked to choose from a
list or provide the driver from a floppy. If you are unsure about what you should choose from the
list, contact your customer service representative.
If your system can still not see the onboard adapter or your hard drives, please fill out the included
customer support form and call your customer support representative. Please pay special attention
to the following information:
• Does the SCSI controller identify itself during POST?
• Can you see the drives being identified at POST either by the system BIOS or the SCSI BIOS?
(You should see the manufacturer’s name and drive type during the Adaptec SCSI scan).
• If you are using a SCSI cable to attach your drives, what kind of terminator do you have at the
end of the cable? (manufacturer and type e.g. ultra 160)
• What memory is being used? Is it on the tested memory list? Contact your customer service
representative for the latest tested memory list.

Hot-Plug PCI Indicator Board Interface (J3D1)
The Hot-Plug PCI Indicator Board (HPIB) contains the necessary LEDs and pushbutton switches
to help the user run PCI Hot-Plug (PHP) operations.
To indicate slot status, each PHP slot contains a green LED and amber LED. The actual
interpretation of the LEDs depends on the operating system running on the system.
Each PHP slot also has a momentary pushbutton switch. When you push this button, the SKA4
baseboard notifies the operating system that a PHP operation on the respective slot is requested. If
PHP operation is supported by the operating system, the user momentarily presses the switch and
then waits for the operating system to signal via the LEDs that the PHP slot has been disabled.
The user can then perform the desired PHP operation on the slot, such as replacing, removing, or
adding a PCI adapter. When the user wants the operating system to enable and initialize the PHP
slot, the user momentarily presses the switch again.
This (Active Low) pushbutton switch for the respective slot is routed to the PRSNT1# input to the
PCI Hot-Plug Controller (PHPC). This switch should not be confused with slot-interlock switches,
which are used in conjunction with mechanical lever designs to prevent access to an energized
PHP slot. The slot interlock inputs into the PHPC are permanently pulled down to ground and are
not accessible through the Hot-Plug PCI Indicator Board interface.
NOTE
✏
The HW push button is located on the Hot-Plug Indicator board. Do not use
this button to turn power on and off to the PCI slot. In some instances,
pushing this button interrupts normal operation of the operating system.
Instead, turn power off using a Hot-Plug PCI application.
The Hot-Plug PCI Indicator Board interface contains the necessary signals to drive the LEDs and
receive the pushbutton signals.
A 20-pin connector is provided on the baseboard for connection to the external HPIB. The pin out
for this connector is given in the table below.
