Description This section describes the microprocessor, connectors, memory subsystems, and miscellaneous system functions and ports for the ThinkPad computers. Microprocessor The ThinkPad 770 uses the Intel Pentium 200 or 233 MHz processor with the MMX technology. The Processor has a 32-bit address bus and a 64-bit data bus. It is software-compatible with all previous microprocessors. The Processor has an internal, split data and instruction, 32KB write-back cache.
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 invalidated. 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.
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 1 mA 5.0 V 0.5 V 2.0 V 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). For scan codes assigned to each numbered key, refer to the IBM Personal System/2 Hardware Interface Technical Reference. Figure 2-3.
Figure 2-4. Key Numbers for the 85-Key Keyboard Keyboard ID The keyboard ID consists of 2 bytes: hex 83AB (the built-in keyboard with the external numeric keypad) or hex 84AB (the built-in keyboard only). Interrupt 16H, function code (AH)=0AH, returns the keyboard ID.

Diskette Drive and Controller Figure 2-9 shows the read, write, and format capabilities of the diskette drive for the ThinkPad computer. Format Size Diskette Type 3.5-inch 1.0 MB Diskette 3.5-inch 2.0 MB Diskette 720 KB 1.2 MB 1.44 MB RWF − − RWF − RWF Legend:: 1 KB (kilobyte) 1 MB (megabyte) R W F 1024 bytes 1,048,576 bytes Read Write Format Figure 2-9.
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 128 KB memory. ROM is active when power is turned on and is assigned to the top of the first and last 1 MB of address space (hex 000F0000–000FFFFF and hex FFFF0000–FFFFFFFF).
System Memory Map Memory is mapped by the memory controller registers. Figure 2-10 on page 2-17 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 1 MB blocks of system board memory starting at or above the hex 100000 boundary.
System Board Memory for the DIMM Connectors The system board has two DIMM connectors. Figure 2-11 shows the pin assignments for the DIMM connector.
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.
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 A B C D 0 1 2 3 4 5 6 7 8 9 10 11 12 13 Figure 2-15.
Bits 6–5 If these bits are a pattern of 01, the oscillator is turned on and the RTC is allowed to keep time. The next update will occur at 500 ms after a pattern of 01 is written to these bits. Bits 4 To use the original bank of memory, select 0. To use the extended registers, select 1. Bits 3–0 These bits allow the selection of a divider output frequency or disable the divider output.
Bit 2 This bit indicates whether the binary-coded-decimal (BCD) or binary format is used for time-and-date calendar updates. If set to 1, this bit indicates binary format. The system initializes this bit to 0. Bit 1 This bit indicates whether the hours byte is in 12-hour or 24-hour mode. If set to 1, this bit indicates the 24-hour mode. The system initializes this bit to 1. Bit 0 If set to 1, this bit enables the daylight-saving-time mode.
Bit 7 This read-only bit monitors the internal battery. If set to 1, this bit indicates that the real-time clock has power. If set to 0, it indicates that the real-time clock has lost power and the data in CMOS is no longer valid. Bits 6–0 These bits are reserved. CMOS RAM Configuration Figure 2-20 shows the bit definitions for the CMOS RAM configuration bytes.
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 If set to 1, this bit indicates that a coprocessor is installed. Bit 0 If 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 640 KB address space. The value in these bytes represents the number of 1 KB blocks of base memory. For example, hex 0280 indicates 640 KB. 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 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.
System Control Port A (Hex 0092) Bit Function 7–4 3 2 1 0 Reserved Security lock latch Reserved (must be set to 0) Alternate gate A20 Alternate hot reset Figure 2-30. System Control Port A (Hex 0092) Bits 7–4 These bits are reserved. Bit 3 This bit provides a security lock for the secured area of RT/CMOS. If this bit is set to 1, the 8-byte power-on password is locked by the software. After this bit is set by POST, it can be cleared only by turning the system off. Bit 2 This bit is reserved.
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. 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.
Bit 6 If set to 1, this bit indicates that a channel check has occurred. Bit 5 If read, this bit indicates the condition of the timer/counter 2 ‘output’ signal. Bit 4 If read, this bit toggles for each refresh request. Bit 3 If set to 0, this bit enables the channel check. This bit is set to 1 during a power-on reset. Bit 2 If set to 0, this bit enables the PCI SERR#. Bit 1 If set to 1, this bit enables the speaker data. Bit 0 If set to 1, this bit enables the timer 2 gate.
The supervisor password protects the system information in Easy-Setup from being changed by unauthorized persons. For more information about these passwords, refer to the ThinkPad User's Guide. 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.
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, the command and status organization of these interfaces is maintained. The functional interfaces for the computer are compatible with the following: The Intel 8259 interrupt controllers (edge trigger mode). The Intel 8254 timers driven from 1.193 MHz (channels 0, 1, and 2).
Error Codes POST returns a three or more character code message to indicate the type of test that failed. Figure 2-33 lists the failure indicated with the associated error code.

Overview 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 following BIOS service level: 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 and output parameter area in its data area, and informs this area by pushing those pointers onto its stack before the far-calls. The SMAPI BIOS uses the stack/data area directly with the selector when the BIOS is invoked.
