Description

The IBM Personal System/2 Hardware Interface Technical Reference

describes devices common to the PS/2* AT-bus system family.

The IBM ThinkPad 560/560E computer (hereafter called the 560,

ThinkPad computer, or computer) is a notebook-size computer that

features the AT* bus architecture. Each computer supports one

external diskette drive and one internal hard disk drive.

Programs can distinguish the foregoing models of computers from

other ThinkPad models by reading the system ID: Interrupt 15H,

function code (AH)=23H, (AL)=10H, returns (AL)=0EH for the

560/560E.

The system microprocessor contains an internal cache and cache

controller.

Figure 1-1 lists the model bytes, submodel bytes, and system clock

speed of the system board.

Description

This section describes the microprocessor, connectors, memory

subsystems, and miscellaneous system functions and ports for the

ThinkPad computers. You can find additional information about

these topics in IBM Personal System/2 Hardware Interface Technical

Reference–AT-Bus Subsystems.

Microprocessor

The ThinkPad 560 uses the Intel Pentium 100/120/133MHz

microprocessor. This microprocessor contains a full 32-bit RISC

integer core, a built-in math coprocessor, and a 16KB internal cache

memory.

The ThinkPad 560E uses the Intel Pentium 150/166MHz

microprocessor with the MMX technology. This microprocessor

contains a full 32-bit RISC integer core, a built-in math coprocessor,

and a 32KB on-chip cache memory.

Cache Memory Operation

The cache memory in the Intel Pentium microprocessor enables the

microprocessor to read instructions and data much faster than if the

microprocessor had to access system memory. When an instruction

is first used or data is first read or written, it is transferred to the

cache memory from main memory. This enables future accesses to

the instructions or data to occur much faster.

The cache is disabled and empty when the microprocessor comes

out of the reset state. The cache is tested and enabled during the

power-on self-test (POST).

The cache memory in the Intel Pentium microprocessor is loaded

from system memory in 32-byte increments, each referred to as a

cache line. A cache line is aligned on a paragraph boundary. A

reference to any byte contained in a cache line results in the entire

line being read into the cache memory (if the data was not already in

the cache). When the microprocessor gives up control of the system

bus, the cache memory enters “snoop” mode and monitors all write

and read operations. If memory data is written to a location in the

cache and the cache line is in the “modified” state, the corresponding

cache line is written back to system memory and is invalidated.

2-2 ThinkPad 560/560E System Board

When the microprocessor performs a memory read, the data address

is used to find the data in the cache. If the data is found (a hit), it is

read from the cache memory and no external bus cycle occurs. If

the data is not found (a miss), an external bus cycle is used to read

the data from system memory. If the address of the missed data is

in a cacheable address space, the data is stored in the cache

memory and the remainder of the cache line is read.

When the microprocessor performs a memory write, the data

address is used to search the cache. If the address is found (a hit),

the data is written to the cache and no external bus cycle is used to

write the data to system memory. (If the address of the write

operation was not in the cache memory but was in cacheable

address space, the data is read back into the cache memory and the

remainder of the cache line is read.)

Cacheable Address Space

Cacheable address space is defined as system memory that resides

on the system board (0–640KB and 1MB–40MB or 80MB^ñ). Nothing

in address range hex A0000–BFFFF, I/O address space, or memory

in any AT slot is cached.

ROM address space (hex C0000–C7FFF) is L1 cacheable for code

read operations only. If data in this address range is already in

cache memory and the address range is written to, the cached line is

invalidated and is read again from RAM (in which the BIOS is

shadowed in).

Cacheability of system memory is up to 64MB in the L2 cache, and is up to 4GB in

the on-chip L1 cache.

ThinkPad 560/560E System Board 2-3

Keyboard/Mouse Connector

Each ThinkPad computer has a keyboard/mouse connector where

the IBM mouse, keyboard, or numeric keypad is connected.

Signals

The keyboard and mouse signals are driven by open-collector drivers

pulled to 5 V dc through a pull-up resistor. Figure 2-1 lists the

signals.

Memory

The ThinkPad computers use the following types of memory:

Ÿ Read-only memory (ROM)

Ÿ Random access memory (RAM)

Ÿ Real-time clock/complementary metal-oxide semiconductor RAM

(RT/CMOS RAM)

ROM Subsystem

The ROM subsystem consists of four banks of 128KB memory.

ROM is active when power is turned on and is assigned to the top of

the first and last 1MB of address space (hex 000F0000–000FFFFF

and hex FFFF0000–FFFFFFFF). After POST checks that system

memory is operating correctly, the ROM code is copied to RAM at

the same address space, and ROM is disabled.

RAM Subsystem

The RAM subsystem on the system board starts at address

hex 00000000 of the address space. The RAM subsystem for the

ThinkPad 560 is 64 bits wide.

The 8MB (ThinkPad 560) or 16MB (ThinkPad 560E) base memory is

on the system board. One 144-pin 8-byte dual inline memory

module (DIMM) connector is provided on the system board. This

connector accepts a 8MB, 16MB, 32MB, or 64MB¹DIMM. The

memory capacity can be increased up to 40MB (ThinkPad 560) or

80MB (ThinkPad 560E) when a DIMM is used (see “System Board

Memory Connector for DIMM” on page 2-14).

The total amount of usable memory is less than the amount of

memory installed because of ROM-to-RAM remapping and power

management.

A 64MB DIMM is supported by ThinkPad 560E only.

ThinkPad 560/560E System Board 2-13

System Memory Map

Memory is mapped by the memory controller registers.

Figure 2-10 shows the memory map for a correctly functioning

system. Memory can be mapped differently if POST detects an error

in system board memory or RT/CMOS RAM. In the figure, the

variable x represents the number of 1MB blocks of system board

memory starting at or above the hex 100000 boundary.

RT/CMOS RAM I/O Operations

During I/O operations to the RT/CMOS RAM addresses, you should

mask interrupts to prevent other interrupt routines from changing the

RT/CMOS address register before data is read or written. After I/O

operations, you should leave the RT/CMOS address and NMI mask

Attention

The operation following a write to hex 0070 should access hex

0071; otherwise, intermittent failures of the RT/CMOS RAM can

occur.

Writing to the RT/CMOS RAM requires the following:

1. Write the RT/CMOS RAM address to the RT/CMOS address and

NMI mask register (hex 0070).

2. Write the data to the RT/CMOS data register (hex 0071).

3. Write the address, hex 0F, to the RT/CMOS and NMI mask

byte (hex 0F).

4. Read address hex 0071 to restore the RT/CMOS.

Reading from the RT/CMOS RAM requires the following steps:

1. Write the RT/CMOS RAM address to the RT/CMOS and NMI

mask register (hex 0070).

2. Read the data from the RT/CMOS data register (hex 0071).

3. Write the address, hex 0F, to the RT/CMOS and NMI mask

byte (hex 0F).

4. Read address hex 0071 to restore the RT/CMOS.

Miscellaneous System Functions and Ports

This section provides information about nonmaskable interrupts

(NMIs), the power-on password, and hardware compatibility.

Nonmaskable Interrupt (NMI)

The NMI signals the system microprocessor that a parity error or a

channel check timeout has occurred. This situation can cause lost

data or an overrun error on some I/O devices. The NMI masks all

other interrupts. The interrupt return (IRET) instruction restores the

interrupt flag to the state it was in before the interrupt occurred. A

system reset causes a reset of the NMI.

The NMI requests from system board parity and channel check are

subject to mask control with the NMI mask bit in the RT/CMOS

Address register. See “RT/CMOS Address and NMI Mask Register

(Hex 0070)” on page 2-17. The power-on default of the NMI mask is

1 (NMI disabled). Before the NMI is enabled after a power-on reset,

the parity-check states are initialized by POST.

Attention

The operation following a write to hex 0070 should access hex

0071; otherwise, intermittent failures of the RT/CMOS RAM can

occur.

This bit is reserved.

Bit 1

This bit is used to enable the ‘address 20’ signal (A20)

when the microprocessor is in the real address mode.

When this bit is set to 0, A20 cannot be used in real

mode addressing. This bit is set to 0 during a system

reset.

Bit 0

This bit provides an alternative method of resetting the

system microprocessor. This alternative method

supports operating systems requiring faster operation

than that provided on the IBM Personal Computer AT.

Resetting the system microprocessor switches the

microprocessor from protected mode to real address

mode.

This bit is set to 0 by either a system reset or a write

operation. When a write operation changes this bit from

0 to 1, the ‘processor reset’ signal is pulsed after the

reset has occurred. While the reset is occurring, the

latch remains set so that POST can read this bit. If the

bit is set to 0, POST assumes that the system was just

powered on. If the bit is set to 1, POST assumes that

the microprocessor has been switched from protected

mode to real mode.

When bit 0 is used to reset the system microprocessor

to the real mode, use the following procedure:

1. Disable all maskable and nonmaskable interrupts.

2. Reset the system microprocessor by writing a 1 to

bit 0.

3. Issue a Halt instruction to the system

microprocessor.

4. Reenable all maskable and nonmaskable interrupts.

2-28 ThinkPad 560/560E System Board

If you do not follow this procedure, the results are

unpredictable.

Note: Whenever possible, use BIOS as an interface to

reset the system microprocessor to the real

mode. For more information about resetting the

system microprocessor, refer to the IBM Personal

System/2 and Personal Computer BIOS

Interface.

Power-On Password

RT/CMOS RAM has 8 bytes reserved for the power-on password

and the check character. The 8 bytes are initialized to hex 00. The

microprocessor can access these bytes only during POST. After

POST is completed, if a power-on password is installed, the

password bytes are locked and cannot be accessed by any program.

During power-on password installation, the password (1 to 7

characters) is stored in the security space.

Installing the password is a function of the built-in system program

Easy-Setup. The power-on password does not appear on the screen

when it is installed, changed, or removed. After the power-on

password has been installed, it can be changed or removed only

during POST.

The computer also can have a keyboard password. For more

information, see the keyboard and auxiliary device controller section

of the IBM Personal System/2 Hardware Interface Technical

Reference.

Selectable Drive-Startup Sequence

Selectable drive-startup (selectable boot) allows you to control the

startup sequence of the drives in your computer. The order in which

the computer looks for the drives for your operating system is the

drive-startup sequence. If you are working with multiple operating

systems, you might want to change the drive-startup sequence to

load the operating system from the hard disk without first checking

the diskette drive, or to do a remote program load (RPL).

ThinkPad 560/560E System Board 2-29

Attention

When changing your startup sequence, you must be extremely

careful when doing write operations (such as copying, saving, or

formatting). Your data or programs can be overwritten if you

select the wrong drive.

For more information about the selectable drive-startup sequence,

refer to the ThinkPad User's Guide.

Hardware Compatibility

The computer supports most of the interfaces used by the IBM

Personal Computer AT* and the Personal System/2* (PS/2*)

products. In many cases, command and status organization of these

interfaces are maintained.

The functional interfaces for the computer are compatible with the

following:

Ÿ The Intel 8259 interrupt controllers (edge trigger mode).

Ÿ The Intel 8254 timers driven from 1.193 MHz (channels 0, 1, and

2).

Ÿ The Intel 8237 DMA controller-address/transfer counters, page

registers, and status fields only. The command and request

registers, and the rotate and mask functions, are not supported.

The mode register is partially supported.

Ÿ The NS16550 serial communications controller.

Ÿ The Intel Pentium microprocessor (ThinkPad 560) or

the Intel Pentium processor with the MMX technology (ThinkPad

560E).

Ÿ The Intel 8086**, 8088**, 80286**, 80386**, and i486DX

microprocessors.

Ÿ The Intel 8087**, 80287**, 80387** math coprocessors.

Ÿ The Intel 82077AA** diskette drive controller.

Ÿ The keyboard interface at addresses hex 0060 and hex 0064.

Ÿ Display modes supported by the IBM Monochrome Display and

Printer Adapter, the IBM Color/Graphics Monitor Adapter, and the

IBM Enhanced Graphics Adapter.

A-2 ThinkPad 560/560E SMAPI BIOS

What is SMAPI BIOS?

The ThinkPad Basic Input/Output System (BIOS) provides a special

software interface, called the System Management Application

Program Interface (SMAPI) BIOS, to control the following unique

features of the ThinkPad system:

System Information

This BIOS provides unique ThinkPad information, such as

the system identifier (system ID).

System Configuration

The ThinkPad SMAPI BIOS provides system configuration

control for such features as display device selection or

resource configuration for built-in devices.

Power Management

Through the SMAPI BIOS, the operating system or

application software can control the ThinkPad power

management features (the Power mode or

Suspend/Hibernation/Resume options).

“Header Image” on page A-4 describes how to use the SMAPI BIOS.

ThinkPad 560/560E SMAPI BIOS A-3

Header Image

Systems that support SMAPI BIOS must provide the following header

image in the F000 segment system ROM area at the 16-byte

boundary. The client needs to search and find this SMAPI BIOS

header image to get the entry point for the service.

image.

Version (Major/Minor)

Indicates the SMAPI BIOS version.

Length

The length of the header image.

Checksum Checksum byte area. The client verifies that this

header image is valid by using this checksum; the client

should check all header image bytes, and the result will

be zero bytes.

below.

Bit 2

Bit 3-15 : Reserved

Real Mode Entry Point

The entry point is specified in segment, offset format.

Clients using Real/V86 mode can use this area for the

far-call value.

16-bit/32-bit Protected Mode Entry Point

The code base code address specifies the physical

address for this BIOS, and the client must prepare the

selector for this BIOS. The length should be 64KB.

ThinkPad 560/560E SMAPI BIOS A-5

Calling Convention

The client can invoke the SMAPI BIOS with a far-call to the entry

point that is specified in the header file. All parameters for the BIOS

and other results are stored in the client data area; the client needs

to prepare an input parameter / output parameter area in its data

area, and informs this area by pushing those pointers onto the its

stack before the far-calls.

The SMAPI BIOS uses the stack/data area directly with the selector

when the BIOS is invoked. Therefore, the caller needs to define the

same privilege level as the BIOS.

Parameter Structure

The memory allocation for the input/output field should be prepared

by the caller. The input field specifies the function request to the

SMAPI BIOS, and the BIOS fills in the return value to the output

field.
