Page 59 4. Position the SIMM at an angle over the empty SIMM socket, as shown below. 5. Push the SIMM into the socket until it is seated firmly in the slot. Then tilt it upright, as shown below, guiding the hole at each end of the SIMM over the retaining post at each end of the SIMM socket.
Page 60: Removing Slmms
Removing SlMMs If you need to remove SIMMs from your computer (to install different ones, for example), make sure the computer is turned off and then follow the steps below: 1. Remove any option cards that may be blocking your access to the SIMM sockets.
Page 61: Installing An Option Card
3. As you pull away the tabs, the SIMM falls to the side. Remove it from the socket. 4. If necessary, follow the same procedure to remove the other SIMM. 5. If you are inserting different SIMMs, follow the instructions on page 4-11 to install your new SIMMs.
Page 62 Check the components on your option card and the system board before deciding which slot to use. Make sure that no components are touching or obstructing other cards or cables. Caution Make sure the power requirements for the option cards you install do not exceed the power supply limitations.
Page 63 Remove the two retaining screws securing the power supply to the back of the computer and the third retaining screw holding the power supply to the base of the computer, as shown below. Be careful not to disconnect any of the cables. Slide the power supply out of the way.
Page 64 3. Slide out the slot cover and set it aside. (Store it in a safe place in case you remove the option card later.) 4. Unpack the option card and adjust any switches or jumpers on it, if necessary. (Check the option card instructions.) When you handle the card, be careful not to touch any of the components on the circuit board or the gold-edged connectors.
Page 65: Removing An Option Card
Once the connectors reach the slot, push the card in firmly (but carefully) to insert it fully. You should feel the card fit into place. If it does not go in smoothly, do not force it; pull the card all the way out and try again. 6.

Page 68: Adding Video Memory
Adding Video Memory Your computer comes with 1MB of video memory. You can increase your video memory to 2MB by installing two video DRAM, 256KB x 16-bit, 40-pin, ZIP (Zig-zag Inline Package) chips. This is useful for running graphics-intensive applications or for supporting high resolutions with many colors.
Page 69 Caution To avoid generating static electricity and damaging the memory chips, ground yourself by touching the metal surface on the inside of the computer’s back panel. Then remain as stationary as possible while you install them. 3. Remove the memory chips from their package and inspect each one.
Page 70: Installing External Cache
6. When the chip is properly positioned, push down firmly on both ends of the chip to make sure it is well-seated. 7. Repeat steps 4 through 6 for the other chip. 8. Replace any option cards you removed. See page 4-14 for instructions.

Page 97: Installing Vga And Ide Drivers
Your computer’s built-in VGA adapter is 100% compatible with IBM VGA. This adapter allows you to use the computer with Epson VGA monitors, other brands of VGA monitors, and VGA compatible, multifrequency monitors that use analog input. The drivers described in this chapter work with any of these monitors.
Page 98 The Drivers diskette that came with your computer contains drivers for Microsoft Windows, version 3.1. Other drivers are available from the Epson Electronic Bulletin Board; call (310) 782-4531 to request additional drivers. The Drivers diskette also contains a utility program called SetRES, which allows you to change your screen resolutions from within the Windows environment.
Page 99: Installing The Windows Drivers
Installing the Windows Drivers If you have not yet installed Windows 3.1, follow the instructions in your Windows documentation to install it. Select VGA as the default display device. Then follow these steps to install the new drivers: 1. Within Windows, select Run from the file menu in the Program Manager.
Page 100: Setres
3. Select Change System Settings. 4. Select Display. 5. From the Display menu, select Other (Requires disk provided by a hardware manufacturer). 6. When the program prompts you to insert your display driver diskette and displays the path A : \, insert the Drivers diskette and press Enter.
Page 101: Ide Drivers
Select the resolution, font size, and number of colors you want to use and select Once you have changed options using the SetRES utility, you need to restart Windows for the new settings to take effect. Drivers The IDE drivers allow your system to take advantage of the high-speed performance of the local bus IDE hard disk drive interface.
Page 102 Note Not all hard disk drives can take advantage of this feature. To take advantage of the local bus IDE interface, your hard disk drive must support a 32-bit data path that utilizes double-word I/O. To find out whether your hard drive utilizes double-word I/O, see the hardware specifications for the drive or contact the vendor of the drive and request a product specification.

See your operating system manual for instructions. Also, make sure your hard disk drive has been physically formatted by the manufacturer. (All Epson-supplied drives are physically formatted at the factory.) If it has not been physically formatted, use the format utility that came with the drive to format it before you partition it or install the operating system.

Page 133: Glossary
Glossary Access speed The time it takes for a device, such as memory or a disk drive, to return data. For example, your computer’s SIMMs return data requested by the microprocessor at an access speed of 70ns. Address The location where information is stored in a computer’s memory.
Page 134 B o o t The process a computer performs to check its components and then load the operating system into memory. A wire or group of wires that sends information between components in the computer. The speed of a bus increases by the number and width of the channels the bus uses to move data.
Page 135: Extended Memory
Central Processing Unit. The primary device that interprets instructions, performs tasks, keeps track of stored data, and controls input and output operations. See also Microprocessor. Device driver A file containing instructions that allow your computer to recognize and communicate with a device. The device may be a printer, monitor, or other type of device.
Page 136: Internal Cache
Integrated Drive Electronics. A type of hard disk drive interface in which the controller is on the drive instead of on a controller card. Your computer includes an interface on the main system board for up to two IDE hard disk drives. Internal cache Cache memory built into your microprocessor.
Page 137: Memory Module
Main system board The circuit board inside your computer containing the circuitry and components your computer needs to operate. Math coprocessor A device that enables the computer to process mathematical calculations faster by using floating point numbers instead of whole numbers. Megabyte (MB) A unit used to measure storage space in a computer’s memory...
Page 138: Processor Speed
Parallel An interface that transmits data simultaneously over separate wires in a cable. See also Serial. Pathname The directory name(s) you specify to locate a file. For example, the pathname for the file SALES, stored in the subdirectory BUSINESS, is \BUSINESS\SALES. Power-on diagnostics Tests stored in a computer’s ROM that the computer runs to check its internal circuitry, peripheral device configuration, and...
Page 139: Shadow Ram
Refresh rate The frequency with which a monitor can redraw a screen image. The faster the refresh rate, the less the screen will flicker. Reset To restart a computer without turning it off. You can reset your computer by pressing Ctrl Alt Del. Resetting erases all data stored in RAM and reloads your operating system.
Page 140 SIMM See Memo y module. Subdirectory In a hierarchical disk directory structure, a group of files in a directory within another directory or the root directory. True Color A VGA feature that supports 24-bit-per-pixel color, which enables your VGA interface to display 16.8 million colors. The screen image looks more like a photograph than a traditional computer image.
