Appendix B
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 correct most problems by
adjusting a cable connection, repeating a software procedure, or
resetting the computer.
Besides trying these suggestions, you can run diagnostics
checks on the various components of your system. See
Appendix C for instructions. If the suggestions here or in
Appendix C do not solve the problem, see “Where to Get Help”
in the Introduction.
Identifying Your System
When you request technical assistance from your dealer, a
qualified service person, or the Epson Customer Resource
Center, be ready to provide your computer’s serial number (on
its back panel), its configuration (including the type of disk
drives, monitor, and option cards), and the names and version
numbers of any software programs you are using.
If you are able to use MS-DOS, you can obtain your MS-DOS
version number and the version number of your computer’s
ROM BIOS.
If you copied the ROMBIOS.COM file to your hard disk (as
described in Chapter 3), follow these steps:
1. At the MS-DOS command prompt, type
ROMBIOS
and
press (You may need to log onto the directory where
ROMBIOS.COM is stored.) Write down the version number
displayed on your screen.
