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.

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.

SKA4 Baseboard Product Guide  
Each slot is identified by another notation. Sockets A1 through A4 are identified as J1 through J4  
respectively. Sockets B1 through B4 are identified as J5 through J8. Sockets C1 through C4 are  
identified as J9 through J12. Sockets D1 through D4 are identified as J13 through J16.  
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, IBM OS/2, Microsoft Windows NT, and various  
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.  
NOTE  
DIMM sizes and compatibility: Use DIMMs that have been tested for  
compatibility with the baseboard. For a list of approved DIMMs, see the  
SKA4 Memory Qualification List. The document can be found on  
http://support.intel.com/support/motherboards/server/SKA4/compat.htm.

Peripherals  
Super I/O Chip (SIO)  
The NationalPC97317VUL 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 CompaqsPHP 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  
Intel® 82559 Fast Ethernet Multifunction PCI/CARDBus controller. The Intel 82559 controller is  
a highly integrated PCI LAN controller in a 196-pin Ball Grid Array (BGA) supporting 10 or  
100 Mbps fast Ethernet networks.  
Supported network features include:  
Glueless 32-bit PCI Bus Master Interface compatible with the PCI Local bus Specification  
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.

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 power-  
down 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

IDE Controller  
IDE is a 16-bit interface for intelligent disk drives with ATdisk 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® 8042A microcontroller. The  
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.  
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® LANDesk® Server Manager, Intel Server Control (ISC), or Direct  
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"

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.  
Table 4.  
Feature  
Software Security Features  
Description  
Secure mode  
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).  
Disable writing to diskette  
In secure mode, the server will not boot from or write to a diskette unless a  
password is entered. To set this feature, use the SSU Security Subsystem  
Group.  
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.  
Disable the power and  
reset buttons  
Power and reset buttons are always disabled when the server is in secure mode.  
Set a time out period so  
that keyboard and mouse  
input are not accepted  
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.  
Also, screen can be  
blanked, and writes to  
diskette can be inhibited  
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.

Software Security Features (continued)  
Description  
Control access to using  
the SSU: set  
To control access to setting or changing the system configuration, set an  
administrative password and enable it through Setup or the SSU.  
administrative password  
If both the administrative and user passwords are enabled, either can be used to  
boot the server or enable the keyboard and/or mouse, but only the  
administrative password will allow Setup and the SSU to be changed.  
To disable a password, change it to a blank entry or press CTRL-D in the  
Change Password menu of the Administrative Password Option menu found in  
the Security Subsystem Group.  
If you cannot access Setup or the SSU to clear the password, change the Clear  
Password jumper. See "CMOS Clear Jumper" on page 109.  
Control access to the  
system other than SSU:  
set user password  
To control access to using the system, set a user password and enable it  
through Setup or the SSU.  
To disable a password, change it to a blank entry or press CTRL-D in the  
Change Password menu of the User Password Option menu found in the  
Security Subsystem Group.  
If you cannot access Setup or the SSU to clear the password, change the Clear  
Password jumper. See "CMOS Clear Jumper" on page 109.  
Boot without keyboard  
The system can boot with or without a keyboard. During POST, before the  
system completes the boot sequence, the BIOS automatically detects and tests  
the keyboard if it is present and displays a message. There is no entry in the  
SSU to enable or disable a keyboard.  
Specify the boot  
sequence  
The sequence specified on the menu in the SSU MultiBoot Group will determine  
the boot order. If secure mode is enabled (a user password is set), then the  
user is prompted for a password before the server fully boots. If secure mode is  
enabled and the “Secure Boot Mode” option is also enabled, the server fully  
boots but requires a password before accepting any keyboard or mouse input.

loaded, the boot process continues and the system beeps once. The following message is  
displayed:  
Operating System not found  
5. At this time, pressing any key causes the system to attempt a reboot. The system searches all  
removable devices in the order defined by the boot priority.  
6. If you want to boot from a hard drive loaded with an operating system, make sure that the hard  
drive is installed and push the Reset button on the front panel.  
28  
SKA4 Baseboard Product Guide  
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.  
Run Setup: Run Setup to modify any standard PC-ATbaseboard feature such as:  
Select diskette drive  
Select parallel port  
Select serial port  
Set time/date (to be stored in RTC)  
Configure hard drive(s)  
Specify boot device sequence  
Enable SCSI BIOS  
Run SSU, not Setup: Run the SSU instead of Setup to do the following:  
Enter or change information about a board  
Alter system resources (e.g., interrupts, memory addresses, I/O assignments) to user-selected  
choices instead of choices selected by the BIOS resource manager  
Record Setup Settings  
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  
prompt.  
When you have moved the CMOS jumper on the baseboard to the “Clear CMOS” position  
(enabled); for a step-by-step procedure, see “CMOS Clear Jumper” on page 109.  
In the three conditions listed above, the following prompt is displayed:  
Press <F2> to enter SETUP  
Configuration Software and Utilities  
29  
In a fourth condition, when CMOS/NVRAM has been corrupted, these other prompts are  
displayed, but not the <F2> prompt:  
Warning: cmos checksum invalid  
Warning: cmos time and date not set  
In this condition, the BIOS loads default values for CMOS and attempts to boot.

You cannot change or configure the option in that  
menu screen for one of the following reasons:  
The option is auto-configured or auto-detected.  
You must use a different Setup screen to change it.  
You must use the SSU.  
On screen, the phrase Press Enter appears next  
to the option.

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 servers 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.  
For more information, see the documentation accompanying your SMM2 card.  
Creating SSU Diskettes  
When creating SSU diskettes, the system copies the SSU from the CD to the diskettes.  
1. Make sure that the CD-ROM is the first bootable device for the system.  
2. Place the CD in the CD-ROM drive and boot the system.  
3. Use the arrow keys to highlight "Create Diskettes" and press <Enter>.  
4. Make sure "Create Disk Sets by Device/Function" is highlighted and press <Enter>.  
5. Make sure "System Setup Utility" is highlighted and press <Enter>.  
6. The software prompts you to insert a blank diskette. Insert the diskette in the floppy drive.  
7. After the system formats the diskette, remove it from the drive and label it "SSU Disk 1".  
8. The software prompts you to insert another blank diskette. Insert the diskette in the floppy  
drive.  
9. After the system creates the diskette, remove it from the drive and label it "SSU Disk 2".  
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 Windows98/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 Operation  
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 Re-  
direct 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.

SKA4 Baseboard Product Guide  
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

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 Nonvolatile Storage 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.

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 protection: 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 ground any unpainted metal surface on 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, needle-  
nosed 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.

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.

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 server starts beeping  
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.

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.

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.

Processor Termination, Regulation, and Power  
The termination circuitry required by the Intel Pentium III Xeon processor bus (AGTL+) signaling  
environment and the circuitry to set the AGTL+ reference voltage, are implemented directly on the  
processor cards. The baseboard provides 1.5 V AGTL+ termination power (VTT), and VRM  
8.3-compliant DC-to-DC converters to provide processor power (VCCP) at each connector. The  
baseboard provides three embedded and three VRM sockets to power the processors, which derive  
power from the +5 V and 12 V supplies. Each processor has a separate VRM to power its core;  
however, two processors share a VRM to power their cache.

Termination Card  
You must install a termination card in any vacant processor card slot to ensure reliable system  
operation.  
The termination card contains AGTL+ termination circuitry, clock signal termination, and Test  
Access Port (TAP) bypassing for the vacant connector. The system does not boot unless all slots  
are occupied with a processor or termination card.  
Server Monitor Module Connector (J7H1)  
The baseboard supports the Server Monitor Module feature connector. The table below shows the  
pinout of the 26-pin baseboard connector.  
On the SKA4 baseboard, pins 1, 9, 15, and 17 are connected to SMI_L, NMI, SECURE_MODE,  
and CHASSIS_INTRUSION. Some server systems do not monitor these signals.

SM Bus Connector (J9E4)  
This connector allows connection to the Memory Module I2C bus that the DIMMs EEPROMs  
reside on. A shorted I2C connection at the SM Bus I2C connector will prevent the system BIOS  
from sizing and configuring main memory.

ICMB Connector (J1D2)  
The external Intelligent Management Bus (ICMB) provides external access to IMB devices that are  
within the chassis. For example, you can externally access chassis management functions, alert  
logs, and post-mortem data. The ICMB connector also provides a mechanism for chassis power  
control. As an option, you can configure a server with an ICMB adapter board to provide two  
SEMCONN 6-pin connectors for daisy chained cabling.

Auxiliary I2C Connector (J9E4)  
TheSKA4 baseboard provides a 3-pin auxiliary I2C connector for OEM access to the IPMB. This  
connector is not isolated when power is off. Any devices connected must remain powered in this  
state or the BMC will not work properly.  
A shorted I2C connection at the auxiliary I2C connector will prevent restoration of main power  
because the BMC needs the bus to boot the server from standby power.

Baseboard Fan Connectors (J3C1, J3A1, J4A1, J4C1)  
There are four fan connectors located on the baseboard. These connectors are to be used for  
additional processor cooling.  
The SKA4 baseboard only supports monitoring a total of 8 tachometer fan inputs. The front panel  
connector provides connections to all 8 tachometer fan inputs. The tachometer signals from these  
four processor fan connectors are connected to the same tachometer fan signals FAN_TACH(4),  
FAN_TACH(5), FAN_TACH(6), FAN_TACH(7) provided on the front panel connector J9E3.  
Therefore take care to ensure only one connection is utilized at any given time.

If pins 5 and 6 of J9F2 are jumpered (default), the current system password is maintained  
during system reset. If pins 6 and 7 are jumpered, the password is cleared on reset.  
BIOS  
Recovery  
If pins 9 and 10 of J9F2 are jumpered (default), BIOS jumps to a protected area of the flash  
part containing the "Recovery BIOS." If the normal BIOS gets corrupted, and you are unable  
to reload a fresh copy from the floppy disk, install the jumper between pins 10 and 11 of J9F2,  
which enables the system to boot from the Recovery BIOS. This code expects a fresh copy of  
the normal BIOS to be located on a floppy disk present in the floppy drive.  
Changing Jumper Settings  
CAUTIONS  
Electrostatic discharge (ESD) and ESD protection: 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 ground any unpainted metal surface on 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.  
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, needle-  
nosed 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.

CMOS Clear Jumper  
The jumper at pins 1, 2, and 3 controls whether settings stored in CMOS nonvolatile memory  
(NVRAM) are retained during a system reset. The jumper is used to restore the system’s CMOS  
and RTC to default values.  
There are two methods to restore the default values.  
Method 1  
1. Hold the system's reset button down for five seconds.  
2. While continuing to hold down the system's reset button, press the power button.  
3. Release both the reset and power buttons at the same time.  
Method 2  
1. Observe the safety and ESD precautions at the beginning of this procedure.  
2. Turn off all connected peripherals, turn off system power, and disconnect all AC power cords.  
3. If the baseboard is installed in a system, remove access covers so that you have access to the  
baseboard.  
4. Remove the memory module. See "Removing the Memory Module" on page 61.  
5. Locate the configuration jumpers at the edge of the baseboard next to the memory expansion  
card connector (MECC).  
6. Move the CMOS jumper from pins 1 and 2 to pins 2 and 3 (the Clear CMOS memory  
position).  
7. If the baseboard is installed in a system, reinstall the access covers, connect the power cords,  
and turn on the system for the change to take effect.  
8. You may need to repeat these steps to move the jumper back to its original setting, depending  
on the jumper function.  
9. Wait for POST to complete and for the messages “NVRAM cleared by jumper” and “Press F1  
to resume, Press F2 to Setup” to be displayed. This automatically reprograms CMOS and RTC  
to their default settings, except for the password.  
10. Enter Setup and make any changes necessary (for example, changing the boot device). Press  
F10 to save the new Setup configuration and exit Setup.  
11. Turn off the system, and disconnect all AC power cords from the system.  
12. Move the jumper from pins 2 and 3 back to pins 1 and 2 (the Protect CMOS memory position).  
13. If the baseboard is installed in a system, reinstall the access covers, connect the power cords,  
and turn on the system for the change to take effect.  
14. Run BIOS Setup or the SSU to verify the correct settings. See Chapter 3.  
Technical Reference

Password Clear Jumper  
The jumper at pins 5, 6, and 7 controls whether a stored password is retained or cleared during a  
system reset.  
Procedure to clear the current password and then enter a new one:  
1. Observe the safety and ESD precautions at the beginning of this procedure.  
2. Turn off all connected peripherals, turn off system power, and disconnect all AC power cords.  
3. If the baseboard is installed in a system, remove access covers so that you have access to the  
baseboard.  
4. Remove the memory module. See "Removing the Memory Module" on page 61.  
5. Locate the configuration jumpers at the edge of the baseboard next to the memory expansion  
card connector (MECC).  
6. Move the Password jumper from pins 5 and 6 to pins 6 and 7.  
7. If the baseboard is installed in a system, reinstall the access covers, connect the power cords,  
and turn on the system for the change to take effect.  
8. Wait for POST to complete and for the message Press F1 to resume, Press F2 to Setup  
to be displayed.  
9. Turn off the system, and disconnect all AC power cords from the system.  
10. Move the jumper from pins 6 and 7 back to pins 5 and 6.  
11. If the baseboard is installed in a system, reinstall the access covers, connect the power cords,  
and turn on the system for the change to take effect.  
12. Run BIOS Setup or the SSU to specify a new password. See Chapter 3.  
Recovery Boot Jumper  
The jumper at pins 9, 10, and 11 controls whether the system attempts to boot using the BIOS  
programmed in flash memory.  
Procedure to disable recovery booting:  
1. Observe the safety and ESD precautions at the beginning of this procedure.  
2. Turn off all connected peripherals, turn off system power, and disconnect all AC power cords.  
3. If the baseboard is installed in a system, remove access covers so that you have access to the  
baseboard.  
4. Remove the memory module. See "Removing the Memory Module" on page 61.  
5. Locate the configuration jumpers at the edge of the baseboard next to the memory expansion  
card connector (MECC).  
6. Move the recovery boot jumper from pins 9 and 10 to pins 10 and 11.  
7. If the baseboard is installed in a system, reinstall the access covers, connect the power cords,  
and turn on the system for the change to take effect.  
8. Turn the system on, and insert the Flash Memory Update Utility diskette in drive A. After the  
system boots, the recovery process starts. This takes about three minutes. When the recovery  
process completes, the speaker emits two beeps.  
110  
SKA4 Baseboard Product Guide  
While in the recovery mode, there is no screen display on the monitor. The keyboard is disabled as  
the system automatically recovers the BIOS. The following beep codes describe the recovery  
status.

9. Wait for POST to complete and for the message “Press F1 to resume, Press F2 to Setup” to be  
displayed.  
10. Turn off the system, and disconnect all AC power cords from the system.  
11. Move the jumper from pins 6 and 7 back to pins 5 and 6.  
12. If the baseboard is installed in a system, reinstall the access covers, connect the power cords,  
and turn on the system for the change to take effect.  
13. After running the special recovery mode, run the SSU to specify a new password. See  
Chapter 3.  
Interrupts  
The table below recommends the logical interrupt mapping of interrupt sources; it reflects a typical  
configuration, but a user can change these interrupts. Use the information to determine how to  
program each interrupt. The actual interrupt map is defined using configuration registers in the  
OSB4 I/O controller. I/O Redirection Registers in the I/O APIC are provided for each interrupt  
signal; the signals define hardware interrupt signal characteristics for APIC messages sent to local  
APIC(s).  
NOTE  
To disable the IDE controller and reuse the interrupt: if you plan to  
disable the IDE controller to reuse the interrupt for that controller, you must  
physically unplug the IDE cable from the board connector (IDE0) if a cable  
is present. Simply disabling the drive by configuring the SSU option does  
not make the interrupt available.

Installation Instructions  
CAUTION  
Follow these guidelines to meet safety and regulatory requirements when  
installing this board assembly.  
Read and adhere to all of these instructions and the instructions supplied with the host computer  
and associated modules. If the instructions for the host computer are inconsistent with these  
instructions or the instructions for associated modules, contact the supplier’s technical support to  
find out how you can ensure that your computer meets safety and regulatory requirements. If you  
do not follow these instructions and the instructions provided by host computer and module  
suppliers, you increase safety risk and the possibility of noncompliance with regional laws and  
regulations.  
Ensure EMC Compliance  
Before computer integration, make sure that the host chassis, power supply, and other modules  
have passed EMC certification testing. This will assist in your end EMC testing and verification  
for compliance.  
In the installation instructions for the host chassis, power supply, and other modules pay close  
attention to the following:  
Certifications (see "Ensure Host Computer and Accessory Module Certifications”)  
External I/O cable shielding and filtering  
Mounting, grounding, and bonding requirements  
Keying connectors when mismatching of connectors could be hazardous  
126  
SKA4 Baseboard Product Guide  
Ensure Host Computer and Accessory Module Certifications  
Make sure that the host computer, any added subassembly (such as a board or drive assembly,  
including internal or external wiring), are certified for the region(s) where the end product will be  
used. Marks on the product are proof of certification. Certification marks are as follows:  
In Europe  
The CE marking signifies compliance with all relevant European requirements. If the host  
computer does not bear the CE marking, obtain a supplier’s Declaration of Conformity to the  
appropriate standards required by the European EMC Directive and Low Voltage Directive. Other  
directives, such as the Machinery and Telecommunications Directives, may also apply depending  
on the type of product. No regulatory assessment is necessary for low voltage DC wiring used  
internally or wiring used externally when provided with appropriate overcurrent protection.  
Appropriate protection is provided by a maximum 8 Amp current limiting circuit or a maximum  
5 Amp fuse or positive temperature coefficient (PTC) resistor. This Intel server board has PTCs  
on all external ports that provide DC power externally.  
In the United States  
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL, CSA, or  
ETL signifies compliance with safety requirements. External wiring must be UL Listed and  
suitable for the intended use. Internal wiring must be UL Listed or Recognized and rated for  
applicable voltages and temperatures. The FCC mark (Class A for commercial or industrial only  
or Class B for residential) signifies compliance with electromagnetic interference requirements.  
In Canada  
A nationally recognized certification mark such as CSA or cUL signifies compliance with safety  
requirements. No regulatory assessment is necessary for low voltage DC wiring used internally or  
wiring used externally when provided with appropriate overcurrent protection. Appropriate  
protection is provided by a maximum 8 Amp current limiting circuit or a maximum approved  
5 Amp fuse or positive temperature coefficient (PTC) resistor. This server board has PTCs on all  
external ports that provide DC power externally.  
Prevent Power Supply Overload  
Do not overload the power supply output. To avoid overloading the power supply, make sure that  
the calculated and measured total current load of all the modules within the computer is less than  
the maximum output current rating of the power supply. If you do not do this, the power supply  
may overheat, catch fire, or damage the insulation that separates hazardous AC line circuitry from  
low voltage user accessible circuitry and result in a shock hazard. If the load drawn by a module  
cannot be determined by the markings and instructions supplied with the module, contact the  
module supplier’s technical support.  
Regulatory Specifications
