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.
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.
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. Sink current High-level output voltage Low-level output voltage High-level input voltage Low-level input voltage 20 mA 5.0 V dc minus pullup 0.5 V dc 2.0 V dc 0.
Scan Codes Figure 2-3 shows the key numbers assigned to keys on the 84-key keyboard (for the U.S. and Japan). Figure 2-4 on page 2-6 shows the key numbers assigned to keys on the 85-key keyboard (for countries other than the U.S. and Japan).

Diskette Drive Connector The external diskette drive is connected through the diskette drive connector, located on the left side of the computer.
Memory The ThinkPad computers use the following types of memory: Read-only memory (ROM) Random access memory (RAM) 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).
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 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. Bit Function 7 6–0 NMI mask RT/CMOS RAM address Figure 2-13. RT/CMOS Address and NMI Mask Register (Hex 0070) Bit 7 When this write-only bit is set to 1, the NMI is masked (disabled).
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.
Real-Time Clock Bytes (Hex 000–00D): Bit definitions and addresses for the real-time clock bytes are shown in Figure 2-15. Address (Hex) Function 000 001 002 003 004 005 006 007 008 009 00A 00B 00C 00D Seconds Second alarm Minutes Minute alarm Hours Hour alarm Day of week Date of month Month Year Status register Status register Status register Status register Byte Number 0 1 2 3 4 5 6 7 8 9 10 11 12 13 A B C D Figure 2-15.

Status Register B (Hex 00B) Bit Function 7 6 5 4 3 2 1 0 Set Enable periodic interrupt Enable alarm interrupt Enable update-ended interrupt Enable square wave Date mode 24-hour mode Enable daylight-saving time Figure 2-17. Status Register B (Hex 00B) Bit 7 When set to 0, this bit updates the cycle, normally by advancing the count at a rate of one cycle per second.
Bit 0 When set to 1, this bit enables the daylight-saving-time mode. When set to 0, this bit disables the daylight-saving-time mode, and the clock reverts to standard time. The system initializes this bit to 0. Status Register C (Hex 00C) Bit Function 7 6 5 4 3–0 Interrupt request flag Periodic interrupt flag Alarm interrupt flag Update-ended interrupt flag Reserved Figure 2-18. Status Register C (Hex 00C) Note: Interrupts are enabled by bits 6, 5, and 4 in status register B.
CMOS RAM Configuration Figure 2-20 shows the bit definitions for the CMOS RAM configuration bytes. Diagnostic Status Byte (Hex 00E) Bit Function 7 6 5 4 3 2 1, 0 Real-time clock power Configuration record and checksum status Incorrect configuration Memory size mismatch Hard disk controller/drive C initialization status Time status indicator Reserved Figure 2-20. Diagnostic Status Byte (Hex 00E) Bit 7 When set to 1, this bit indicates that the real-time clock has lost power.
Diskette Drive Type Byte (Hex 010): This byte indicates the type of the installed diskette drive. Bit Drive Type 7–4 3–0 Diskette drive type Reserved Figure 2-21. Diskette Drive Type Byte (Hex 010) Bits 7–4 These bits indicate the diskette drive type. Bits 7–4 Description 0110 Diskette drive (2.88MB) 0100 Diskette drive (1.44MB) Note: Combinations not shown are reserved. Figure 2-22. Diskette Drive Type Bits 7–4 Bits 3–0 These bits are reserved.
Hard Disk Drive Type Byte (Hex 012): This byte defines the type of hard disk drive installed. Hex 00 indicates that no hard disk drive is installed. Bit Drive Type 7–4 3–0 Hard disk drive 0 Hard disk drive 1 Figure 2-26. Hard Disk Drive Type Byte Reserved Bytes (Hex 013): These bytes are reserved. Equipment Byte (Hex 014): This byte defines the basic equipment in the system for the power-on diagnostic tests.
Bits 3–2 These bits are reserved. Bit 1 When set to 1, this bit indicates that a coprocessor is installed. Bit 0 When set to 1, this bit indicates that physical diskette drive 0 is installed. Low and High Base Memory Bytes (Hex 015 and Hex 016): The low and high base memory bytes define the amount of memory below the 640KB address space. The value in these bytes represents the number of 1KB blocks of base memory. For example, hex 0280 indicates 640KB. The low byte is hex 015; the high byte is hex 016.
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.
System Control Port B (Hex 0061) Bit definitions for the write and read functions of this port are shown in the following figures: Bit Function 7–4 3 2 1 0 Reserved Reserved (should be 0) Enable parity check Enable speaker data Timer 2 gate to speaker Figure 2-30. System Control Port B (Hex 0061, Write) Bit Function 7 6 5 4 3 2 1 0 Parity check Channel check Timer 2 output Toggles with each refresh request Reserved Enable parity check Enable speaker data Timer 2 gate to speaker Figure 2-31.
System Control Port A (Hex 0092) Bit Function 7–3 2 1 0 Reserved Reserved (must be set to 0) Alternate gate A20 Alternate hot reset Figure 2-32. System Control Port A (Hex 0092) Bits 7–3 These bits are reserved. Bit 2 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.
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.
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.

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).
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.
Information Word This area identifies the BIOS service level defined below. Information Bit Bit Bit Bit Word ð 1 2 3-15 : : : : Real/V86 mode interface support 16-bit protected mode support 32-bit protected mode support 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.
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.
