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.
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.
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.
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.
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. Figure 2-9. Diskette Drive Read, Write, and Format Capabilities Diskette Type Format Size 720 KB 1.2 MB 1.44 MB 3.
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.
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.
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. Figure 2-11.
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.
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).
Real-Time Clock Bytes (Hex 000–00D): Bit definitions and addresses for the real-time clock bytes are shown in Figure 2-15. Figure 2-15. Real-Time Clock Bytes (Hex 000–00D) Address (Hex) Function B.
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.
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.
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.
Diskette Drive Type Byte (Hex 010): This byte indicates the type of the installed diskette drive. Figure 2-21. Diskette Drive Type Byte (Hex 010) Bit Drive Type 7–4 Diskette drive type 3–0 Reserved Bits 7–4 These bits indicate the diskette drive type.
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. Figure 2-26. Hard Disk Drive Type Byte Bit Drive Type 7–4 Hard disk drive 0 3–0 Hard disk drive 1 Reserved Bytes (Hex 013): These bytes are reserved.
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.
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.
System Control Port A (Hex 0092) Figure 2-30. System Control Port A (Hex 0092) Bit Function 7–4 Reserved 3 Security lock latch 2 Reserved (must be set to 0) 1 Alternate gate A20 0 Alternate hot reset Bits 7–4 These bits are reserved. Bit 3 This bit provides a security lock for the secured area of RT/CMOS.
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.
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.
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 .
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.
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. Figure 2-33 (Part 1 of 2). Error Codes Error Code Description 101 Interrupt failure.

Ein wichtiger Punkt beim Kauf des Geräts IBM 770 (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie IBM 770 noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen. Schauen Sie zuerst die ersten Seiten der Anleitung durch, die Sie oben finden. Dort finden Sie die wichtigsten technischen Daten für IBM 770 - auf diese Weise prüfen Sie, ob das Gerät Ihren Wünschen entspricht. Wenn Sie tiefer in die Benutzeranleitung von IBM 770 reinschauen, lernen Sie alle zugänglichen Produktfunktionen kennen, sowie erhalten Informationen über die Nutzung. Die Informationen, die Sie über IBM 770 erhalten, werden Ihnen bestimmt bei der Kaufentscheidung helfen.
Wenn Sie aber schon IBM 770 besitzen, und noch keine Gelegenheit dazu hatten, die Bedienungsanleitung zu lesen, sollten Sie es aufgrund der oben beschriebenen Gründe machen. Sie erfahren dann, ob Sie die zugänglichen Funktionen richtig genutzt haben, aber auch, ob Sie keine Fehler begangen haben, die den Nutzungszeitraum von IBM 770 verkürzen könnten.
Jedoch ist die eine der wichtigsten Rollen, die eine Bedienungsanleitung für den Nutzer spielt, die Hilfe bei der Lösung von Problemen mit IBM 770. Sie finden dort fast immer Troubleshooting, also die am häufigsten auftauchenden Störungen und Mängel bei IBM 770 gemeinsam mit Hinweisen bezüglich der Arten ihrer Lösung. Sogar wenn es Ihnen nicht gelingen sollte das Problem alleine zu bewältigen, die Anleitung zeigt Ihnen die weitere Vorgehensweise – den Kontakt zur Kundenberatung oder dem naheliegenden Service.
