Chapter 1: Introduction
1-13
1-2 Chipset Overview
Intel’s 845 chipset is made up of three main components:
*82845 Memory Controller Hub (MCH) with Accelerated Hub Architecture
(AHA) bus,
*82801 BA I/O Controller Hub (ICH2) with AHA bus,
*82802 AB Firmware Hub (FWH).
Memory Controller Hub (MCH)
The MCH includes the host (CPU) interface, SDRAM interface, ICH2 interface and 4xAGP interface for the 845 chipset. It contains advanced power
management logic and supports three DIMMS of unbuffered SDRAM up to
3GB. The AGP 2.0 interface supports 4x data transfers and operates at a
peak bandwidth of 1056 GB. The MCH host interface bus runs at 400 MHz.
I/O Controller Hub (ICH2)
The ICH2 is the I/O Controller Hub subsystem on the P4SBA+/P4SBA/P4SBM,
which integrates many of the Input/Output functions of the 845 chipset,
including a two-channel ATA-33/66/100 Bus Master IDE controller. It also
provides the interface to the PCI Bus and communicates with the MCH over
a dedicated hub interface bus -- the AHA. The P4SBA+/P4SBA has the
more powerful ICH2, which includes a dual channel IDE controller plus two
USB controllers that offer 24 Mbps of bandwidth across four ports. ICH2
also features an enhanced AC97 interface that supports full surround
sound for the Dolby Digital Audio used on DVDs (P4SBA+ and P4SBM only).
Firmware Hub (FWH)
The FWH is a component that brings added security and manageability to
the PC platform infrastructure. This device includes an integrated Random
Number Generator (RNG) for stronger encryption, digital signing and security protocols. The FWH stores the system BIOS and video BIOS to eliminate
a redundant nonvolatile memory component.
1-14
SUPER P4SBA+/P4SBA/P4SBM User’s Manual
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond
when AC power is lost and then restored to the system. You can choose
for the system to remain powered off (in which case you must hit the
power switch to turn it back on) or for it to automatically return to a power
on state. See the Power Lost Control setting in the BIOS chapter of this
manual to change this setting. The default setting is Always OFF.
1-3 Special Features
Communication and Networking Riser
The CNR slot supports audio, modem and networking cards and provides
interfaces that support multichannel audio, V.90 analog modems, home networking through a telephone line, 10/100 Ethernet-based networking and
future technologies. Separating sound and communications systems from
the motherboard makes them less sensitive to noise.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
P4SBA+/P4SBA/P4SBM. All have an onboard System Hardware Monitor
chip that supports PC health monitoring.
Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V,
++
++
+5V and
±±
±±
±12V
The onboard voltage monitor will scan these seven voltages continuously.
Once a voltage becomes unstable, it will give a warning or send an error
message to the screen. Users can adjust the voltage thresholds to define
the sensitivity of the voltage monitor.
Chapter 1: Introduction
1-15
Three-Fan Status Monitor with Firmware/Software On/Off
Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin CPU and chassis fans are controlled by the power management functions. The thermal fan is controlled by the overheat detection
logic.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and
will turn on the thermal control fan whenever the CPU temperature exceeds
a user-defined threshold. The overheat circuitry runs independently from
the CPU. It can continue to monitor for overheat conditions even when the
CPU is in sleep mode. Once it detects that the CPU temperature is too high,
it will automatically turn on the thermal control fan to prevent any overheat
damage to the CPU. The onboard chassis thermal circuitry can monitor the
overall system temperature and alert users when the chassis temperature
is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It can be turned off
when the CPU is in sleep mode. When in sleep mode, the CPU will not run
at full power, thereby generating less heat.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat temperature. When this temperature is exceeded, both the overheat fan and the
warning LED are turned on.
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager
(optional). It is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insufficient hard drive space for saving the data, you can be alerted of the
potential problem.
1-16
SUPER P4SBA+/P4SBA/P4SBM User’s Manual
Hardware BIOS Virus Protection
The system BIOS is protected by hardware so that no virus can infect the
BIOS area. The user can only change the BIOS content through the flash
utility provided by SUPERMICRO. This feature can prevent viruses from
infecting the BIOS area and destroying valuable data.
Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to
60A current and auto-sense voltage IDs ranging from 1.1V to 1.85V. This
will allow the regulator to run cooler and thus make the system more stable.

ACPI is an acronym for Advanced Configuration and Power Interface. The
ACPI specification defines a flexible and abstract hardware interface that
provides a standard way to integrate power management features throughout a PC system, including its hardware, operating system and application
software. This enables the system to turn on and off peripherals such as
CD-ROMs, network cards, hard disk drives and printers automatically. This
also includes consumer devices connected to the PC such as VCRs, TVs,
telephones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating system-independent interface for configuration control. ACPI leverages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Windows 98/2000 and Windows NT 4.0. Note: To utilize ACPI, you must reinstall Windows 98. To reinstall Windows 98 with ACPI, enter DOS and type
"setup /p J" at the CDROM prompt (usually D:\) with the Windows 98 CD
loaded. (Make sure you include the spaces after "setup" and "p".) Then
press <Enter>. You can check to see if ACPI has been properly installed by
looking for it in the Device Manager, which is located in the Control Panel in
Windows.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term for a PC that is always
on but appears to be off and responds immediately to user or other re-

quests.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking
and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it keyboard will
function like a normal keyboard during system boot-up.
Real Time Clock Wake-Up Alarm
Although the PC may be perceived to be off when not in use, it is still
capable of responding to preset wake-up events. In the BIOS, the user can
set a timer to wake-up the system at a predetermined time.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button. When the user depresses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Depressing the power button again will cause
the whole system to wake-up. During the SoftOff state, the ATX power
supply provides power to keep the required circuitry in the system alive. In
case the system malfunctions and you want to turn off the power, just
depress and hold the power button for 4 seconds. The power will turn off
and no power will be provided to the motherboard.
Wake-On-Ring Header
Wake-up events can be triggered by a device such as the external modem
ringing when the system is in the SoftOff state. Note that external modem
ring-on can only be used with an ATX 2.01 (or above) compliant power
supply.

1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA
logic. The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports four 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M
disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to remotely power up a computer that is powered off. Remote PC setup, updates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Wake-On-LAN
must be enabled in BIOS. Note that Wake-On-Lan can only be used with an
ATX 2.01 (or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates of 1.4+ GHz.
The SUPER P4SBA+/P4SBA/P4SBM accommodates ATX 12V power supplies. Although most power supplies generally meet the specifications required by the CPU, some are inadequate.
It is strongly recommended that you use a high quality power supply that
meets ATX 12V power supply Specification 1.1 or above. Additionally, in
areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recommended that
you also install a power surge protector to help avoid problems caused by
power surges.

It also provides two high-speed, 16550 compatible serial communication
ports (UARTs), one of which supports serial infrared communication. Each
UART includes a 16-byte send/receive FIFO, a programmable baud rate
generator, complete modem control capability and a processor interrupt system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s,
which support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI
power management through a SMI or SCI function pin. It also features auto
power management to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can be flexibly
adjusted to meet ISA PnP requirements, which suppport ACPI and APM (Advanced Power Management).
