  • Page 15: Setting Up Your-System

    Chapter 1 Setting Up Your System This chapter describes how to set up and start using your computer system for the first time. Before you set up your system, be sure to read the “Important Safety Instructions” at the beginning of this manual. Preparing to Set Up Your System It is important to choose a safe, convenient location for your system that provides the following:...

  • Page 16: Installation Overview

    If the power cord supplied with your system is not compatible with the AC wall outlet in your region, obtain a suitable power cord that meets the following criteria: The power cord must be rated for at least 125% of the current rating of the AC voltage system.
  • Page 17 The keys for the front panel door lock are taped to the inside of the door. Open the door to remove the keys. (It might be a little hard to open the door the first time.) Install any optional equipment you want to add to your computer, such as disk drives, memory modules, or EISA option cards.

  • Page 18: Setting The Voltage Selector Switch

    Setting the Voltage Selector Switch Your system is powered by a 230 watt power supply. The power supply voltage is controlled by a voltage selector switch on the computer’s back panel that may be set to 115 VAC or 230 VAC. The computer is shipped with the voltage selector switch set to 115 VAC.

  • Page 19: Installing Optional Equipment

    Caution Before you turn on the power to your system, you must be sure the voltage selector switch is set to the appropriate setting for the electrical power source in your location or you will seriously damage your system. To change the voltage selector switch setting, insert the tip of a ball-point pen or a similar tool into the dimple on the switch.

  • Page 20: Connecting Peripheral Devices

    If you plan to install any ISA cards that came with their own CFG files, you should install the cards after you have connected the necessary peripheral devices and run the computer’s EISA Configuration utility. This allows you to add the CFG file information to your configuration so the program can give you the card’s correct jumper and switch settings.
  • Page 21 Before connecting the peripheral devices, make sure the power buttons or switches on the computer and all peripheral devices are turned off. Then follow these steps to connect the peripheral devices: If necessary, insert the mouse cable connector into the mouse port on the back panel.

  • Page 22: Turning On The System

    Turning On the System Read the following safety rules to avoid damaging the computer or injuring yourself Do not connect any power or peripheral device cables when the computer’s power is on. Never turn on the computer while a protective card is in a 5.25-inch diskette drive.
  • Page 23 Follow these steps to turn on the system: Make sure all peripheral devices, such as the mouse, keyboard, and monitor, have been connected. Turn on the monitor and any other peripheral devices. Turn on your system by pressing the power button on the front panel.

  • Page 24: Configuring Your System

    Configuring Your System There are two programs you can use to configure your computer: the SETUP program and the EISA Configuration utility.

Most EISA option cardsdraw 2A. If you install a card drawing more than 2A, install it in a lowernumbered slot (such as 1 or 2) to ensure adequate cooling.

  • Page 205: Glossary

    Glossary Accessspeed The length of time it takes for an information storage device, such as memory or a disk drive, to return a piece of data requested by another device. For example, your computer’s SIMMs return data requested by the microprocessor at an access speed of 70ns or 80ns (nanoseconds).
  • Page 206 BIOS Basic Input/ Output System. Routines in ROM (Read Only Memory) that handle the transfer of information among various hardware components, and between the hardware and your operating system and other software. A wire or group of wires that sends information from component to component in the computer.
  • Page 207 Conventional memory The memory in the computer below 1MB that is available to MS-DOS and application programs-usually 640KB. Also called base memory or main memory. Coprocessor See Math coprocessor. Copy-protected program A program containing a software “lock” that prevents it from being copied.
  • Page 208 Extended Industry Standard Architecture. A bus standard for IBM compatible computers that extends the ISA bus architecture to 32 bits and allows more than one option card to share the bus easily. Expanded memory Memory that specially written MS-DOS programs can use when an expanded memory manager program maps that memory into an accessible area.
  • Page 209 Integrated Drive Electronics. A type of hard disk drive interface in which the controller is located on the drive, instead of on a controller card. Your computer includes an interface for up to two IDE hard disk drives on the main system board. Industry Standard Architecture.
  • Page 210 Math coprocessor An optional device that enables the computer to process mathematical calculations faster by using floating point numbers instead of whole numbers. This speeds up certain math and graphics operations performed by programs that use this type of calculation. Memory module A small circuit board that contains surface-mounted memory chips.
  • Page 211 Network server The main computer in a network which controls access to the rest of the network computers (called workstations). The server also provides mass storage, programs, and other resources to the workstations. Non-target modeling mode A method you can use to run the EISA Configuration utility to create an SCI file for another computer.
  • Page 212 Random Access Memory. The portion of the computer’s memory used to run programs and store data while you work. All data stored in RAM is erased when you turn off or reset the computer; so you must store any data you want to keep on a storage device.
  • Page 213 Shadow RAM The feature in your computer that copies the contents of the system, video, and any external BIOS ROMs into the RAM area of memory to speed up processing. SIMM See Memory module UNIX A powerful operating system that supports multitasking and is especially suited to multi-user environments.
