Removing an internal hard disk drive Follow these steps to remove an internal hard disk drive: 1. Position the drive housing so the disk drive riser board faces upward and the back of the housing faces you. 2. Loosen the screws securing the drive to the housing with a screwdriver. Then, if you are removing a third-height drive, support the bottom of the drive as you remove the screws from the drive housing by hand. Gently lay the hard disk drive on the base of the housing, if necessary. 3.
Post-installation Setup Procedures After you install or remove options, you need to run the BIOS SETUP program or System Configuration utility to update your system’s configuration information. These programs automatically update the information about some optional equipment, such as additional memory. See the Software Guide for instructions. If you installed a hard disk drive that has never received a low-level format, you need to format the disk.
Chapter 4 Using the SCSI Subsystem This chapter describes the basic operations you need to perform to use the computer’s built-in SCSI-II subsystem. The SCSI-II subsystem consists of the following components: Cl SCSI controller for single-ended SCSI devices LI Internal SCSI hard disk drive connector U External SCSI device port t2 External SCSI device terminator. Your system also comes with SCSI drivers for MS-DOS.
Note If you plan to use a SCSI hard disk drive as the drive from which you load your operating system, be sure you set the following options when you configured your system: Cl Enable the built-in SCSI controller Ll Disable the built-in IDE hard disk drive controller 2 Set both hard disk drive types to Not installed. See your Software Guide for instructions on running either the BIOS SETUP program or the System Configuration utility to check these options.
Installing the SCSI Terminators Your configuration of SCSI devices, both internal and external, will communicate with each other and with the SCSI controller along the SCSI bus. For the SCSI subsystem to operate properly, you must install special resistor packs called terminators to mark the devices on both “ends” of the SCSI bus.
U If you install only an internal SCSI drive, it is automatically terminated by the circuitry on the disk drive riser board when you connect the drive to it. You should install the terminator that came with system to the external SCSI port to terminate the external end of the bus. D If you install external SCSI devices to the computer, follow the instructions in your external SCSI device manuals to install the necessary terminator on the last external device on the bus.
Formatting and Partitioning a SCSI Hard Disk Before you can use your SCSI devices, you must logically format the hard disk drives and partition them for use with your operating system(s). Then you can install your operating system files on the drive you will use to boot the computer. If you are installing MS-DOS, use the FDISK command to format and partition the drives.
Installing the SCSI Device Drivers Check your Software Guide to see if you need to install any SCSI device drivers on your system; then follow the instructions in that manual.
Appendix A Troubleshooting You should not encounter any difficulties as you set up and use your computer, but if anything out of the ordinary happens, refer to this appendix. You can also run System diagnostic tests on various system components. See your Software Guide for instructions. If the suggestions here do not help solve the problem, see “Where to Get Help” in the Introduction for instructions on contacting your dealer or Epson customer service.
2. When you see the operating system command prompt, enter the appropriate command to display the version number of your operating system. (For example, if you are using MS-DOS, type VER and press [.) Write it down, and then obtain the version numbers of any application programs you are using. Error Messages Your computer’s built-m memory (ROM) contains a series of diagnostic programs, called power-on diagnostics.
Power-on Diagnostic and Boot Errors When the power-on diagnostic tests detect an error, the computer displays a message on the screen (as described below) and the speaker beeps twice. If the error occurs before the computer initializes the video display, the speaker sounds a series of beeps (described in the next section). Each error is identified by a message number and a countdown number which the computer uses as it executes the test associated with the error.

The computer does not start when you turn it on. Turn off the power and check the following: 2 Be sure all cables are securely connected to the computer.
The computer starts but does not boot. If the computer starts but does not load your operating system, the problem could be caused by many different factors. First make sure you have correctly formatted your hard disk and have properly installed your operating system on it. (See “Hard Disk Problems” on page A-15.) If you do not have a hard disk, insert a system diskette in drive A and press the reset button. The computer does not respond when you type.
The computer suddenly stops operating. Your computer may have stopped operating because its power supply contains detection circuits that automatically shut down the power if they detect excessive operating temperatures. This protects your system from damage due to overheating. When these circuits detect a high temperature, they shut off all the DC outputs in the power supply and your computer stops operating.
4. If you removed the computer’s cover, replace it now. Then turn on the computer. If the power supply shuts off again after you follow the steps above to correct the problem, contact your dealer. Password Problems If you set a power-on, network, or keyboard password and you have trouble entering it, check the section below that describes the problem you are having. You enter the password, but nothing happens. Type the password again and press [Enter.
3. If you do not have a hard disk, insert a bootable diskette in drive A. Turn on the computer and allow it to load the operating system. 4. Then turn off the computer, remove the cover, and enable the password function by moving main system board jumper J21 from pins 2-4 to pins 4-6. 5. Replace the computer’s cover. If you do not want to set a new password, you do not need to do anything else. (When you turn on your computer, you will not see the Enter password prompt.
Note If you set a new power-on password, it automatically becomes your keyboard password. If you want to set a different keyboard password, see Chapter 1 for instructions. Keyboard Problems CJ Make sure the keyboard is securely connected to its port. U If you are still having problems, see “Power or Lock-up Problems” above. Monitor Problems See the suggestions below if you have trouble with your monitor display. There is no display on the screen.
