Terminology

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

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

determned by counting the number of sectors and assuming thatevery two sectors

equals 1 KB.

Note: Depending on the operating system and other requirements, the storage

capacity available to you might vary.

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.

To learn more about ADSL modems, see the Understanding Your Personal Computer

publication for your personal computer model and type number. This publication is

available on the World Wide Web at http:/ / www.ibm.com/ pc/ support.

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 48 and “Appendix C. IRQ and DMA

channel assignments,” on page 53.

For information on the connector pin assignments, see “IDE connectors” on page 42.

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

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

48 and “Appendix C. IRQ and DMA channel assignments,” on page 53.

The system board has one connector for the keyboard port and one connector for the

mouse port. For information on the connector pin assignments, see “Mouse and

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 one second.

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 PC 300GL and PC 300PL personal computers 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 26. For connector pin

assignments, see “Appendix A. Connector pin assignments,” on page 33.

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 PC 300GL and PC 300PL User Guide and

Understanding Your Personal Computer.

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 PC 300PL and the PC 300GL personal

computers is provided as a startable IBM Enhanced Diagnostic diskette image on the

IBM Product Recovery CD or the Device Driver and IBM Enhanced Diagnostic CD. It runs

independently of the operating system. The user interface is WaterGate Software PC-

Doctor. The diagnostic program can also be downloaded from the following World

Wide Web page: http:/ / www.ibm.com/ pc/ support/ . For more information on the

diagnostic program, see the PC 300GL and PC 300PL User Guide.

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)

National Semiconductor NS16450 and NS126550A serial communications

controllers

•

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

Parallel printer ports (Parallel 1, Parallel 2, and Parallel 3) in compatibility mode

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. Clears the interrupt

2. Waits one I/ O delay

Download from Www.Somanuals.com. All Manuals Search And Download.

3. Sends the EOI

4. Waits one I/ O delay

5. Enables the interrupt through the Set Interrupt Enable Flag command

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).

Appendix B. System address maps

The following charts represent how the hard disk stores different types of

information. Address ranges and byte sizes are approximate.

System memory map

The first 640 KB of system board RAM is mapped starting at address hex 0000000. A

256 byte area and a 1 KB area of this RAM are reserved for BIOS data areas. Memory

can be mapped differently if POST detects an error.

Complete lists of POST and beep error codes are provided in the PC300GL and PC

300PL User Guide and in the Hardware Maintenance Manual.

POST error codes

POST error messages appear when, during startup, POST finds problems with the

hardware or a change in the hardware configuration. POST error messages are 3-, 4-,

5-, 8-, or 12-character alphanumeric messages.

Beep codes

Beep codes are a series of tones in sets of two or three that sound when there are POST

errors. The beep pattern represents numeric values and provides further information

about the location of a potential problem.

The Hardware Maintenance Manual provides a complete list of beep codes.
