Description This section describes the microprocessor, connectors, memory subsystems, and miscellaneous system functions and ports for the ThinkPad 600 computer. Microprocessor The ThinkPad 600 uses the Intel Pentium II 233 MHz processor with MMX technology or the Intel Pentium 233 or 266 MHz processor.
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 invalidated.
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 2-3. Key Numbers for the 85-Key Keyboard Figure 2-4 shows the key numbers assigned to keys on the 86-key keyboard (for countries other than the U.S.and Japan). Figure 2-4. Key Numbers for the 86-Key Keyboard Figure 2-5 on page 2-6 shows the key numbers assigned to the keys on the 90-key keyboard (for Japan).
Figure 2-5. Key Numbers for the 90-Key Keyboard For scan codes assigned to each numbered key, refer to the IBM Personal System/2 Hardware Interface Technical Reference .

Diskette Drive and Controller Figure 2-10 shows the read, write, and format capabilities of the diskette drive for the ThinkPad computer. Figure 2-10. 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 2-11 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.
System Board Memory for the DIMM Connectors The system board has two DIMM connectors. Figure 2-12 shows the pin assignments for the DIMM connector. Figure 2-12.
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 2-16. Figure 2-16. Real-Time Clock Bytes (Hex 000–00D) Address (Hex) Function B.
Status Register B (Hex 00B) Figure 2-18. Status Register B (Hex 00B) Bit Function 7 Set 6 Enable periodic interrupt 5 Enable alarm interrupt 4 Enable update-ended interrupt 3 Enable square wave 2 Date.
Status Register C (Hex 00C) Figure 2-19. Status Register C (Hex 00C) Bit Function 7 Interrupt request flag 6 Periodic interrupt flag 5 Alarm interrupt flag 4 Update-ended interrupt flag 3–0 Reserved Note: Interrupts are enabled by bits 6, 5, and 4 in status register B.
CMOS RAM Configuration Figure 2-21 shows the bit definitions for the CMOS RAM configuration bytes. Diagnostic Status Byte (Hex 00E) Figure 2-21. Diagnostic Status Byte (Hex 00E) Bit Function 7 Real-ti.
Diskette Drive Type Byte (Hex 010): This byte indicates the type of the installed diskette drive. Figure 2-22. 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 2-27. 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 2-31. 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 which test failed. Figure 2-34 lists the failure indicated with the associated error code. Figure 2-34 (Part 1 of 2). Error Codes Error Code Description 101 Interrupt failure.

An important point after buying a device IBM 600 (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
If you have not bought IBM 600 yet, this is a good time to familiarize yourself with the basic data on the product. First of all view first pages of the manual, you can find above. You should find there the most important technical data IBM 600 - thus you can check whether the hardware meets your expectations. When delving into next pages of the user manual, IBM 600 you will learn all the available features of the product, as well as information on its operation. The information that you get IBM 600 will certainly help you make a decision on the purchase.
If you already are a holder of IBM 600, but have not read the manual yet, you should do it for the reasons described above. You will learn then if you properly used the available features, and whether you have not made any mistakes, which can shorten the lifetime IBM 600.
However, one of the most important roles played by the user manual is to help in solving problems with IBM 600. Almost always you will find there Troubleshooting, which are the most frequently occurring failures and malfunctions of the device IBM 600 along with tips on how to solve them. Even if you fail to solve the problem, the manual will show you a further procedure – contact to the customer service center or the nearest service center
