Description 5
Processor
The SAI2 server board accommodates one or two 1.0 GHz Intel Pentium III processors with
256K cache support that are designed for the PGA370 socket. The PGA370 is a 370-pin zeroinsertion
force (ZIF) socket. The processor(s) interface with the system bus at 133 MHz.
For a complete list of supported processors, see:
http://support.intel.com/support/motherboards/server/SAI2
Dual Processor Operation
The Pentium III processor interface is multi-processor (MP)-ready. Each processor contains a local
Intel?? Advanced Programmable Interrupt Controller (APIC) section for interrupt handling. When
two processors are installed, both processors must be of identical revision, core voltage, and
bus/core speeds.
Boxed Processor Fan Heat sink
The boxed Pentium III processor is supplied with a fan heat sink. After the processor is installed,
install and connect the fan heat sink to ensure optimal processor cooling. It is recommended that
fan inlet air temperature should be below 45 °C (measured at 0.3 inches above the fan hub).
CAUTION
Clearance is required around the fan heat sink to ensure unimpeded airflow
for proper cooling. Restricting the airflow through the processor heat sink
can cause overheating and subsequent failure of the processor.
ServerWorks ServerSet III LE Chipset
The SAI2 server includes a ServerWorks ServerSet III LE chipset that provides an integrated
I/O bridge and memory controller, and a flexible I/O subsystem core (PCI).
CNB30LE
The CNB30LE is responsible for:
• Accepting access requests from the host (processor) bus and for directing those accesses to
memory or to one of the PCI buses
• Controlling data transfers to and from main memory
• Providing the interface for both the 64-bit/66-MHz, Revision 2.2-compliant PCI bus and the
32-bit/33-MHz, Revision 2.2-compliant PCI bus
6 Intel Server Board SAI2 Product Guide
CSB5
The CSB5 controller can be both a master and a target on the 32-bit/33-MHz PCI bus and has the
following onboard components:
• USB controller
• IDE controller
• Advanced Configuration and Power Interface (ACPI) control registers and is responsible for
many power management functions
Super I/O
The National† PC87417VUL Super I/O Plug-and-Play Compatible with ACPI-Compliant
Controller/Extender is used on the SAI2 server board. This device provides the system with:
• Real-time Clock (RTC)
• Two serial ports
• One parallel port
• Floppy disk controller (FDC)
• PS/2-compatible keyboard and mouse controller
• General purpose I/O pins
• Plug-and-Play functions
• A power management controller
The SAI2 server board provides the connector interface for the floppy disk drive, dual serial ports,
parallel port, PS/2 mouse and the PS/2 keyboard.
Serial Ports
Two 9-pin D-Sub connectors are provided on the back panel for serial port A and serial port B.
Both ports are compatible with 16550A and 16450 modes. Each serial port can be set to one of
four different COM-x ports, and each can be enabled separately. When enabled, each port can be
programmed to generate edge- or level-sensitive interrupts. When disabled, serial port interrupts
are available to add-in cards.
Parallel Port
The SAI2 baseboard provides a 25-pin parallel port back panel connector. The Super I/O provides
an IEEE 1284-compliant 25-pin bi-directional parallel port. BIOS programming of the Super
I/O registers enables the parallel port and determines the port address and interrupt. When
disabled, the interrupt is available to add-in cards.
Floppy Port
The floppy disk connector (FDC1) on the server board provides the interface to the floppy disk
drive from the floppy disk controller.
Description 7
Keyboard and Mouse Connectors
The separate keyboard and mouse connectors, found on the rear panel of the server board, are
PS/2-compatible.
Memory
The SAI2 server board contains four 168-pin DIMM sockets. Memory is partitioned as four banks
of registered SDRAM DIMMs, each of which provides 72 bits of non-interleaved memory (64-bit
main memory plus ECC).
The SAI2 server board supports up to four 3.3-V, registered ECC SDRAM DIMMs that are
compliant with the JEDEC PC133 specification. A wide range of DIMM sizes are supported,
including 64 MB, 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. The minimum supported memory
configuration is 64 MB, using one 64 MB DIMM. The maximum configurable memory size is
4 GB using four 1 GB DIMMs.
CAUTION
The system will not operate properly if either PC100 DIMMs or non-ECC
DIMMs are installed.
DIMMs may be installed in one, two, three, or four DIMM slots and must be populated starting
with Slot 1 and filling the slots in consecutive order. Empty memory slots between DIMMs are not
supported. Although the SAI2 server board architecture allows the user to mix various sizes of
DIMMS, Intel recommends that module and DRAM vendors not be mixed in the same server
system.
✏ NOTE
Use DIMMs that have been tested for compatibility with the server board.
Contact your sales representative or dealer for a current list of approved
memory modules. Check the Intel Customer Support website for the latest
tested memory list:
http://support.intel.com/support/motherboards/server/SAI2

10 Intel Server Board SAI2 Product Guide
Supported Network Features
The 82559 SAI2 supports the following features of the 82559 controller:
• Glueless 32-bit PCI Bus Master Interface (Direct Drive of Bus), compatible with PCI Bus
Specification, revision 2.1 / 2.2
• 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
• Autodetect and autoswitching for 10 or 100 Mbps network speeds
• Support for both 10 Mbps and 100 Mbps networks, full or half duplex-capable, with
back-to-back transmit at 100 Mbps
• Integrated physical interface to TX magnetics
• The magnetics component terminates the 100Base-TX connector interface. A flash device
stores the network ID.
• Support for Wake on LAN (WOL)
Keyboard and Mouse
The keyboard/mouse controller is PS/2-compatible. The server may be locked automatically if
there is no keyboard or mouse activity for a predefined length of time. Once the inactivity
(lockout) timer has expired, the keyboard and mouse do not respond until the previously stored
password is entered.
ACPI
The Advance Configuration and Power Interface (ACPI)-aware operating system can place the
system into a state where the hard drives spin-down, the system fans stop, and all processing is
halted. In this state the power supply is still on and the processors still dissipate some power, such
that the power supply fan and processor fans are still running.
Note: ACPI requires an operating system that supports this feature.
The ACPI sleep states discussed below are defined as:
s0: Normal running state
s1: Processor sleep state. No content is lost in this state and the processor caches maintain
coherency.
s4: Hibernate or Save to Disk. The memory and machine state are saved to disk. Pressing the power
button or another wakeup event restores the system state from the disk and resumes normal
operation. This assumes that no hardware changes were made to the system while it was off.
s5: Soft off. Only the RTC section of the chip set is running in this state.
The SAI2 server board supports sleep states s0, s1, s4, and s5. When the server board is operating
in ACPI mode, the OS retains control of the system and the OS policy determines the entry
Description 11
methods and wake-up sources for each sleep state – sleep entry and wake-up event capabilities are
provided by the hardware but are enabled by the OS.
With future versions of Microsoft Windows† 9X and Windows 2000 that support ACPI, the system
BIOS supports only sleep states s0, s1, and s5.
CAUTION
The system is off only when the AC power is disconnected.
AC Link Mode
The AC link mode allows the system to monitor its AC input power so that if AC input power is
lost and then restored, the system returns to one of the following pre-selected settings:
• Power On
• Last State (Factory Default Setting)
• Stay Off
The AC link mode settings can be changed by running the BIOS Setup Utility.
Wake On LAN
Wake on LAN allows system power to be activated by way of a network or modem. If the system
power is set to off, it can be turned on remotely by sending a specific packet from the main
computer to the remote system.
✏ NOTE
The standard default value of the remote power-on function is “Disabled”.
The Wake on LAN / Ring function can be changed by setting the option to
“Enabled” in the BIOS Setup Utility.

Password Protection
The BIOS uses passwords to prevent unauthorized tampering with the system. Once secure mode
is entered, access to the system is allowed only after the correct password(s) has been entered. Both
user and supervisor passwords are supported by the BIOS. The user password cannot be set unless a
supervisor password has been set.
When set, a password can be cleared by changing it to a null string. Clearing the supervisor
password also clears the user password. Entering the user password permits modification of the
time, date, language, user password, and password on boot setup fields; other setup fields can be
modified only if the supervisor password is entered. The user password also allows the system to
boot, if secure boot is enabled.
If a wrong password is entered three times in a row, the BIOS stops validating passwords and the
BIOS security engine returns a failure for any further password validation attempt. If the user
enters three wrong passwords in a row during the boot sequence (i.e., when entering Setup), the
system is placed into a halt state. This feature makes is difficult to break the password by the “trial
and error” method.
Description 13
Using Passwords
If only the supervisor password is set, you:
• Must enter the supervisor password to enter BIOS Setup.
• Must enter the supervisor password to boot the server if Password on Boot is enabled in the
BIOS Setup.
• Must enter the supervisor password to exit secure mode.
If both passwords are set, you:
• May enter the user password to enter BIOS Setup. However, you will not be able to change
many of the options.
• Must enter the supervisor password if you want to enter BIOS Setup and have access to all of
the options.
• May enter either password to boot the server if Password on Boot is enabled in the BIOS Setup.
• May enter either password to exit secure mode.
Hot Key Activation
A hot key combination allows the user to activate secure mode immediately instead of waiting for
the inactivity time-out to expire. The hot key combination is configured through Setup, with the
following keys are configurable as valid hot keys: Ctrl-Alt <A-Z, 0-9>.
Password Clear Jumper
If the user or supervisor password(s) is(are) lost or forgotten, moving the password clear jumper
into the “clear” position clears both passwords. The password clear jumper must be restored to its
original position before a new password(s) can be set. The password clear jumper is located on
jumper block ‘JP5’ pins [3-4] on the SAI2 board.
Floppy Write Protection
When selected in Setup, the floppy write protection option blocks writes to the floppy disk when
the system is in secure mode. Floppy write protection is in effect only while the system is in secure
mode. When not in secure mode, write protection is disabled and the floppy diskette drive operates
normally.
Secure Boot Mode (Unattended Start)
The Secure Boot mode allows the system to boot and run the operating system (OS) without
requiring the user password, even if the user password is set. However, until the user password is
entered, mouse and keyboard input is not accepted (except for password entry). If Secure Boot is
enabled, secure mode is enabled shortly before boot. To prevent unauthorized tampering with any
option ROM based setup utilities, enable the ‘Option ROM Menu Mask’ setting in the security
menu.
14 Intel Server Board SAI2 Product Guide
Using Secure Boot
Configure and enable the secure boot mode. When secure mode is in effect:
• You can boot the server and the operating system will run, but you must enter the user
password to use the keyboard or mouse.
• You cannot turn off system power or reset the server 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.
Taking the server 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 be powered
off when secure mode is later removed. However, if the front panel power switch remains
depressed when secure mode is removed, the server will be powered off.
Fixed Disk Boot Sector Write Protect
The fixed disk write protect switch is set to ‘Write Protect’ to prevent writes to the fixed IDE disk
boot sector. This feature works only with IDE drives and only the boot sector is write protected.
Power Switch Mask
The power switch mask enables and disables the power switch feature. If set to masked, the system
power cannot be turned off with the power switch after booting the OS. Termination is also
disabled. Termination is a feature that terminates system power when the power switch is held
down for more than four seconds.

2 Configuration Software and Utilities
This chapter describes the Power On Self Test (POST) and server configuration utilities. The table
below briefly describes the utilities.
Table 4. Configuration Utilities
Utility Description and brief procedure Page
BIOS Setup If the system does not have a diskette drive, or the drive is disabled or
mis-configured, use Setup to enable it.
Or, you can move the CMOS jumper on the server board from the default
setting (Protect CMOS memory) to the Clear setting; this will allow most
server configurations to boot. Then use the recovery disk to recover.

Table 5. Hot Keys
To do this: Press these keys
Clear memory and reload the operating
systemthis is a system reset.
<Ctrl+Alt+Del>
Secure your system immediately. The following keys are configurable as valid hot keys:
<Ctrl+Alt>+<A-Z, 0-9>. (Set your hot key combination
with Setup.)
16 Intel Server Board SAI2 Product Guide
Power On Self Test (POST)
Each time you turn on the system, POST starts running. POST checks the server board, processor,
memory, keyboard, and most installed peripheral devices. During the memory test, POST displays
the amount of memory that it is able to access and test. 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 server. After a few seconds POST begins to run.
2. After the memory test, these screen prompts and messages appear:
Press <F2> key if you want to run SETUP
3. If you do not press <F2> and do NOT have a device with an operating system loaded, the
above message remains for a few seconds while the boot process continues, and the system
beeps once. Then this message appears:
Operating system not found
4. Press <Esc> during POST to pop up a boot menu when POST finishes. From this menu you
can choose the boot device or enter BIOS Setup.
After POST completes, the system beeps once.
What appears on the screen after this depends on whether you have an operating system loaded and
if so, which one.
If the system halts before POST completes running, it emits a beep code indicating a fatal system
error that requires immediate attention. If POST can display a message on the video display screen,
it causes the speaker to beep twice as the message appears.
Note the screen display and write down the beep code you hear; this information is useful for your
service representative. For a listing of beep codes and error messages that POST can generate, see
the “Solving Problems” chapter in this manual.
Configuration Software and Utilities 17
Using BIOS Setup Utility
This section describes the BIOS Setup Utility options. Use Setup to change the server
configuration defaults. You can run Setup with or without an operating system being present.
If You Cannot Access Setup
If the diskette drive is misconfigured so that you cannot access it to run a utility from a diskette,
you may need to clear CMOS memory. You will need to open the server, 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 Chapter 5, under the heading, “CMOS Jumper.”
Starting Setup
You can enter and start Setup under several conditions:
• When you turn on the server, after POST completes the memory test
• When you have moved the CMOS jumper on the server board to the “Clear CMOS” position
(enabled); for the procedure, see Chapter 5, under the heading “CMOS Jumper”
In the three conditions listed above, after rebooting, you will see this prompt:
Press <F2> to enter SETUP
In a fourth condition, when CMOS/NVRAM has been corrupted, you will see other prompts but not
the <F2> prompt:
Warning: CMOS checksum invalid
Warning: CMOS time and date not set
In this condition, the BIOS will load default values for CMOS and attempt to boot.
Setup Menus
Each Setup menu page contains a number of features. Except those used for information purposes,
each feature is associated with a value field that contains user-selectable parameters. Parameters
may be changed depending upon the security option chosen. If a value is not changeable due to
insufficient security privileges (or other reasons), the feature’s value field becomes inaccessible.
The bottom portion of the Setup screen provides a list of commands that are used for navigating the
Setup utility.
