Safety Information This section contains the safety information with which you need to be familiar, before you service an IBM computer. General Safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance. v When lifting any heavy object: 1. Ensure you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force.
Observe the following rules when working on electrical equipment. v Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. v Do not work alone under hazardous conditions or near equipment that has hazardous voltages.
Handling electrostatic discharge-sensitive devices Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge. Notes: Use product-specific ESD procedures when they exceed the requirements noted here. 2.
3. Check the power cord for the following: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground. b. The power cord should be the appropriate type as specified in the parts listings. c. Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations. 6.
Problem determination tips Because there is a large variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. v Verify any recent hardware changes. See “Hardware considerations” on page 131. v Verify any recent software changes. See “Software considerations” on page 130. v Verify that the BIOS is at the latest level. See “BIOS” on page 130. v Verify that the drivers are at the latest levels. See “Drivers” on page 130.
Adding adapters to the system When adapters are added to the system, an area in memory has to be allocated to run its programs. This can be done with either hardware switches or software mapping. If there is a conflict in software mapping, then the following may be true. v The first device to attach to an IRQ, DMA, I/O Address, or RAM location will probably function. The second device will not be found.
Not all device drivers are found in the CONFIG.SYS file. Advanced operating systems use .INI files to set up and start devices. Device drivers can access the hardware in five ways. v Operating system direct to hardware using a direct driver Direct drivers, which bypass BIOS, have the advantage of faster throughput, but the disadvantage of limited error-handling capability and reduced software and hardware compatibility and flexibility. This method is not used in the IBM PC Series systems.
v POST Beep codes are sounds emitted from the speaker if the POST finds a problem. One beep indicates that the POST completed successfully. Multiple beeps indicate a problem was found. v Diagnostic error messages are displayed when a test program finds a problem with a hardware component. v Software-generated error messages are displayed if a problem or conflict is found by an application program, the operating system, or both.
ROM and RAM Addresses Adapter cards with processors can contain RAM and ROM. If the adapter cards have onboard memory, then the following are true. v ROM contains operating instructions for the adapter I/O. v RAM is used for buffering. Two adapters using the same memory area will cause a failure. This failure might appear as a hardware failure. The IRQ levels, DMA channels, I/O address, and ROM and RAM addresses all become potential conflicts and system problems.
