Technical Information
Preface
This Technical Information Manual provides information for your computer. This
publication is intended for developers who want to provide hardware and software
products to operate with your computer and provides an in-depth view of how the
computer works. Users of this publication should have an understanding of computer
architecture and programming concepts.
Related publications
In addition to this publication, the following IBM publications provide information
related to the operation of your computer. The publications mentioned here are
available from the IBM Web site. In some cases, you will have to follow further
instructions on the Web site to find the document for your particular computer and
model. To order printed publications, refer to the help information in the User Guide
that comes with your computer.
•

Terminology usage
Attention: The term reserved describes certain signals, bits, and registers that should
not be changed. Use of reserved areas can cause compatibility problems, loss of data,
or permanent damage to the hardware. If you change the contents of a register,
preserve the state of the reserved bits. When possible, read the register first and
change only the bits that must be changed.
In this manual, some signals are represented in an all-capital-letter format (-ACK). A
minus sign in front of the signal indicates that the signal is active low. No sign in front
of the signal indicates that the signal is active high.
The term hex indicates a hexidecimal number.
When numerical modifiers such as K, M, and G are used, they typically indicate
powers of 2, not powers of 10. For example, 1 KB equals 1 024 bytes (210), 1 MB equals
1 048 576 bytes (220), and 1 GB, equals 1 073 741 824 bytes (230).
When expressing storage capacity, MB equals 1 000 KB (1 024 000). The value is
determined by counting the number of sectors and assuming that every two sectors
equals 1 KB.
Note:

Five Universal Serial Bus (USB) connectors
IBM ScrollPoint® II mouse
IBM Rapid Access® III, USB keyboard (some models)
IBM preferred USB keyboard (some models)
Two low-powered USB connectors on the Rapid Access III keyboard
Three 3.5-mm audio jacks (in/headphone out, line in, microphone)
DVD-ROM
DVD-ROM drives, standard on some models, differ from CD-ROM and CD-RW
drives as the result of refinements in laser technology.
The recording tracks on DVD media are not as deep and are more condensed than on
CDs or CD-RWs, therefore DVDs provide more storage space. DVD media also use
both sides of the disk, as opposed to just one side for CDs and CD-RWs.
DVD-ROM drives read traditional CDs, CD-RWs, and DVDs.
ADSL modems
ADSL modems, available on some models, enable simultaneous internet connectivity
and telephone service. Contact your local telephone service provider and ask if your
premises need any additional telephony equipment, such as a splitter or a filter. Also
contact your Internet service provider (ISP) to determine if they provide service to
customers with ADSL.
ADSL modems work by using separately the individual four or six wires in the
standard RJ-11 telephone jack. The inner wires, or pairs of wires if there are six, carry
voice transmissions. The outer wires on either side carry data between your computer
and the Internet. One channel is data download; the other is data upload.
Wake on LAN
The power supply of the computer supports the Wake on LAN feature. With the Wake
on LAN feature, the computer can be turned on when a specific LAN frame is passed
to the computer over the LAN.
To find out if the Wake on LAN feature is set, refer to the menu item for Wake on LAN
in the Configuration/Setup Utility program. See the User Guide for help with using
the Configuration/Setup Utility program.
Wake on Ring
All models can be configured to turn on the computer after a ring is detected from an
external or internal modem. Use the menu for setting the Wake on Ring feature in the
Configuration/Setup Utility Program. See the User Guide for help with using the
Configuration/Setup Utility program. Two options control this feature:

IDE bus master interface
The system board incorporates a PCI-to-IDE interface that complies with the AT
Attachment Interface with Extensions.
The bus master for the IDE interface is integrated into the I/O hub of the SIS630 chip
set. The chip set is PCI 2.2 compliant. It connects directly to the PCI bus and is
designed to allow concurrent operations on the PCI bus and IDE bus. The chip set is
capable of supporting PIO mode 0–4 devices and IDE DMA mode 0–3 devices. Ultra
DMA 66 transfers up to 66 Mbps using an ATA 66 cable.
The IDE devices receive their power through a four-position power cable containing
+5 V dc, +12 V dc, and ground voltage. As devices are added to the IDE interface,
designate one device as the master, or primary, device and another as the slave, or
subordinate, device. These designations are determined by switches or jumpers on
each device. There are two IDE ports, one designated Primary and the other
Secondary, allowing for up to four devices to be attached. The total number of
physical IDE devices is determined by available space on the system board.
For the IDE interface, no resource assignments are given in the system memory or the
direct memory access (DMA) channels. For information on the resource assignments,
see “Input/output address map” on page 34 and “Appendix C. IRQ and DMA
channel assignments,” on page 39.
For information on the connector pin assignments, see “IDE connectors” on page 28.

Audio Subsystem
Your computer comes with an integrated audio controller that is capable of playing
and recording sounds. It supports SoundBlaster, Adlib, and Microsoft Windows
Sound System applications.
The device drivers for the preinstalled audio controller are on the hard disk. The
device drivers are also available on Product Recovery CDs that come with your
computer.
If you connect an optional device to the audio adapter, follow the instructions
provided by the manufacturer.
Note:
Additional device drivers might be required. If necessary, contact the
manufacturer for information on these device drivers.
The following connectors are available on the audio adapter or integrated audio
controller:
•
Line Out port for connecting powered speakers or headphones. You must
connect a set of speakers to the Line Out port to hear audio from the adapter.
These speakers must be powered with a built in amplifier. In general, any
powered speakers designed for use with personal computers can be used with
the audio adapter. These speakers are available with a wide range of features
and power outputs.
•
Line In port for connecting musical devices, such as a portable CD-ROM player
or stereo.
•
Microphone for connecting a microphone.
Integrated peripheral controller
Control of the integrated input/output (I/O) and diskette drive controllers is
provided by a single module, the integrated peripheral controller (SMC FDC 87B813).
This module, which supports Plug and Play technology, controls the following
features:
•
•
Diskette drive interface
Keyboard and mouse ports
Keyboard and mouse ports
A general purpose 8-bit microcontroller, 8042AH compatible, controls the mouse and
keyboard subsystem. The controller consists of 256 bytes of data memory and 2 KB of
read-only memory (ROM).
The controller has two logical devices: one controls the keyboard and the other
controls the mouse. The keyboard has two fixed I/O addresses, a fixed IRQ line, and
can operate without the mouse. The mouse cannot operate without the keyboard
6
Technical Information
because, although it has a fixed IRQ line, the mouse relies on the addresses of the
keyboard for operation. For the keyboard and mouse interfaces, no resource
assignments are given in the system memory addresses or DMA channels. For
information on the resource assignments, see “Input/output address map” on page
34 and “Appendix C. IRQ and DMA channel assignments,” on page 39.
The system board has PS/2 type connectors for a keyboard and mouse. For
information on the connector pin assignments, see “Mouse and keyboard port
connectors” on page 32.

Supports Wake on LAN
The computer has a 3-pin header on the system board that provides the AUX5
(auxiliary 5 volts) and wake-up signal connections.
Real-time clock and CMOS
The real-time clock is low-power and provides a time-of-day clock and a calendar. An
external battery source of 3 V dc maintains the settings.
The system uses 242 bytes of complementary metal-oxide semiconductor (CMOS)
memory to store data. To erase or reset CMOS memory to the default, use the small
rocker switch on the system board.
Note:
Refer to the instructions in the Hardware Maintenance Manual before
attempting to reset CMOS.
To locate the battery see “System board” on page 8.
Flash EEPROM
The system board uses two megabits (Mb) of flash electrically erasable
programmable, read-only memory (EEPROM) to store the basic input/output system
(BIOS), IBM logo, Configuration/Setup Utility, and Plug and Play data.
If necessary, you can update the EEPROM by downloading a stand-alone utility
program available from the IBM Web site: http://www.ibm.com/pc.
Expansion adapters
Each PCI-expansion connector is a 32-bit slot. PCI-expansion connectors support the
32-bit, 5 V dc, local-bus signalling environment defined in PCI Local Bus Specification

Technical Information
These levels were measured in controlled acoustical environments according
to procedures specified by the American National Standards Institute (ANSI)
S12.10 and ISO 7779, and are reported in accordance with ISO 9296. Actual
sound-pressure levels in your location might exceed the average values stated
because of room reflections and other nearby noise sources. The declared
sound power levels indicate an upper limit, below which a large number of
computers will operate.

Note:
Some adapters and hard disk drives draw more current than the rated
maximums. These adapters and drives can be installed in the system;
however, the power supply will shut down if the total power used exceeds
the maximum power that is available.
Output protection
The power supply protects against output overcurrent, overvoltage, and short
circuits. See the power supply specifications on the previous pages for details.
A short circuit that is placed on any dc output (between outputs or between an output
and a dc return) latches all dc outputs into a shutdown state, with no damage to the
power supply. If this shutdown state occurs, the power supply returns to normal
operation only after the fault has been removed and the power switch has been
turned off for at least two seconds.
If an overvoltage fault occurs (in the power supply), the power supply latches all dc
outputs into a shutdown state before any output exceeds 130% of the power supply
value.
Connector description
The power supply for your computer has four, 4-pin connectors for internal devices.
The total power used by the connectors must not exceed the amount shown in
“Component outputs” on page 14. For connector pin assignments, see “Appendix A.
Connector pin assignments,” on page 21.

the on-board system devices and controllers.
POST error codes include text messages for determining the cause of an error. For
more information, see “Appendix D. Error codes,” on page 41 and your User Guide.
Configuration/Setup Utility program
The Configuration/Setup Utility program provides menu choices for devices, I/O
ports, date and time, system security, start options, advanced setup, and power
management.
© Copyright IBM Corp. 2000
17
More detailed information on using the Configuration/Setup Utility program is in the
PC 300GL and PC 300PL User Guide.
Advanced Power Management (APM)
Your computer has built-in energy-saving capabilities. Advanced Power Management
(APM) is a feature that reduces the power consumption of components when they are
not in use. When enabled, APM initiates reduced-power modes for the monitor,
microprocessor, and hard disk drive after a specified period of inactivity.
The BIOS supports APM 1.2. This enables the system to enter a power-management
state, reducing the power drawn from the AC electrical outlet. Advanced Power
Management is enabled through the Configuration/Setup Utility program and is
controlled by the individual operating system.
For more information on APM, see the User Guide.
Advanced Configuration and Power Interface (ACPI)
Advanced Configuration and Power Interface (ACPI) BIOS mode enables the
operating system to control the power-management features of your computer. Not
all operating systems support ACPI BIOS mode. Refer to your operating-system
documentation to determine if ACPI is supported.
Flash update utility program
The flash update utility program is a stand-alone program to support flash updates.
This utility program updates the BIOS code and the machine readable information
(MRI) to different languages.
The latest version of the flash update utility program is available on the IBM Web site
at http://www.ibm.com/pc/support and can be copied to a 3.5-inch diskette.
Diagnostic program
The diagnostic program that comes with your computer is provided as a startable
IBM Enhanced Diagnostic diskette image on the IBM Product Recovery CD. It runs
independently of the operating system. The user interface is WaterGate Software PCDoctor. The diagnostic program can also be downloaded from
http://www.ibm.com/pc/support/ on the World Wide Web. For more information
on the diagnostic program, see the User Guide.

Technical Information
Chapter 6. System compatibility
This chapter discusses some of the hardware, software, and BIOS compatibility issues
for the computer. See the Compatibility Report under, “Related publications” on page
vii for a list of compatible hardware and software options.
Hardware compatibility
This section discusses hardware, software, and BIOS compatibility that must be
considered when designing application programs.
The functional interfaces are compatible with the following interfaces:
•
Intel 8259 interrupt controllers (edge-triggered mode)
•
Motorola MC146818 Time of Day Clock command and status (CMOS
reorganized)
•
Intel 8254 timer, driven from a 1.193 MHz clock (channels 0, 1, and 2)
•
Intel 8237 DMA controller, except for the Command and Request registers and
the Rotate and Mask functions; the Mode register is partially supported
•
Intel 8272 or 82077 diskette drive controllers
•
Intel 8042 keyboard controller at address hex 0060 and hex 0064
•
All video standards using VGA, EGA, CGA, MDA, and Hercules modes
Use this information to develop application programs. Whenever possible, use the
BIOS as an interface to hardware to provide maximum compatibility and portability
of applications among systems.
Hardware interrupts
Hardware interrupts are level-sensitive for PCI interrupts. The interrupt controller
clears its in-service register bit when the interrupt routine sends and End-of-Interrupt
(EOI) command to the controller. The EOI command is sent regardless of whether the
incoming interrupt request to the controller is active or inactive.
The interrupt-in-progress latch is readable at an I/O-address bit position. This latch is
read during the interrupt service routine and might be reset by the read operation or it
might require an explicit reset.
Note:
For performance and latency considerations, designers might want to limit
the number of devices sharing an interrupt level.
With level-sensitive interrupts, the interrupt controller requires that the interrupt
request be inactive at the time the EOI command is sent; otherwise, a new interrupt
request will be detected. To avoid this, a level-sensitive interrupt handler must clear
the interrupt condition (usually by a read or write operation to an I/O port on the
device causing the interrupt). After processing the interrupt, the interrupt handler:
1.
2.
3.
4.
5.

Clears the interrupt
Waits one I/O delay
Sends the EOI
Waits one I/O delay
Enables the interrupt through the Set Interrupt Enable Flag command
19
Hardware interrupt IRQ9 is defined as the replacement interrupt level for the cascade
level IRQ2. Program interrupt sharing is implemented on IRQ2, interrupt hex 0A. The
following processing occurs to maintain compatibility with the IRQ2 used by IBM
Personal Computer products:
1. A device drives the interrupt request active on IRQ2 of the channel.
2. This interrupt request is mapped in hardware to IRQ9 input on the second
interrupt controller.
3. When the interrupt occurs, the system microprocessor passes control to the IRQ9
(interrupt hex 71) interrupt handler.
4. This interrupt handler performs an EOI command to the second interrupt
controller and passes control to the IRQ2 (interrupt hex 0A) interrupt handler.
5. This IRQ2 interrupt handler, when handling the interrupt, causes the device to
reset the interrupt request before performing an EOI command to the master
interrupt controller that finishes servicing the IRQ2 request.
Software compatibility
To maintain software compatibility, the interrupt polling mechanism that is used by
IBM Personal Computer products is retained. Software that interfaces with the reset
port for the IBM Personal Computer positive-edge interrupt sharing (hex address
02Fx or 06Fx, where x is the interrupt level) does not create interference.
Software interrupts
With the advent of software interrupt sharing, software interrupt routines must daisy
chain interrupts. Each routine must check the function value, and if the function value
is not in the range of function calls, that routine must transfer control to the next
routine in the chain. Because software interrupts are initially pointed to address 0:0
before daisy chaining, check for this case. If the next routine is pointed to address 0:0
and the function call is out of range, the appropriate action is to set the carry flag and
initiate a RET 2 to indicate an error condition.
Machine-sensitive programs
Programs can select machine-specific features, but they must first identify the
machine and model type. IBM has defined methods for uniquely determining the
specific machine type. The machine model byte can be found through interrupt 15H,
Return System Configuration Parameters function (AH)=(C0H).
