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. When the contents of a register are changed, the  
state of the reserved bits must be preserved. When possible,  
read the register first and change only the bits that must be  
changed.

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.

an output and a dc return) latches all dc outputs into a shutdown  
state, with no hazardous condition to the power supply.  
If an overvoltage fault occurs in the power supply, the power supply  
latches all dc outputs into a shutdown state before any output  
exceeds 135% of the nominal value of the power supply.

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 80MBñ). 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).  
ñ
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 64MB1 DIMM. 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.  
1
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.

The system board of ThinkPad 560 has one DIMM connector that  
directly accepts one 144-pin DIMM of one of the following three  
different capacities: 8MB, 16MB, or 32MB.  
The system board of ThinkPad 560E has one DIMM connector that  
directly accepts one 144-pin DIMM of one of the following four  
different capacities: 8MB, 16MB, 32MB, or 64MB (2-bank type).

RT/CMOS RAM  
The RT/CMOS RAM (real-time clock/complementary metal-oxide  
semiconductor RAM) module contains the real-time clock and 128  
bytes of CMOS RAM. The clock circuitry uses 14 bytes of this  
memory; the remainder is allocated to configuration and  
system-status information. A battery is built into the module to keep  
the RT/CMOS RAM active when the power supply is not turned on.  
Figure 2-12 lists the RT/CMOS RAM bytes and their addresses.

RT/CMOS Address and NMI Mask Register (Hex 0070)  
The NMI mask register is used with the RT/CMOS data register (hex  
0071) to read from and write to the RT/CMOS RAM bytes.  
Attention  
The operation following a write to hex 0070 should access hex  
0071; otherwise, intermittent failures of the RT/CMOS RAM can  
occur.

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  
register (hex 0070) pointing to status register D (hex 00D).  
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  
register; this leaves hex 0070 pointing to the shutdown status  
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  
register; this leaves hex 0070 pointing to the shutdown status  
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.

Bit 2  
These bits are reserved.  
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.

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.

Bit 1  
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.
