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.
v Do not service the following parts (or similar units) with the power on when they are removed from their normal operating places in a machine. This practice ensures correct grounding of the units.) – Power supply units – Pumps – Blowers and fans – Motor generators v If an electrical accident occurs: – Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.
Safety inspection guide The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.
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 134. v Verify any recent software changes. See “Software considerations” on page 133. v Verify that the BIOS is at the latest level. See “BIOS” on page 133. v Verify that the drivers are at the latest levels. See “Drivers” on page 133.
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.
