I am a new user to DOS, so I am a bit unfamiliar with things. . .
I am using a Packard-Bell AT-Compatible computer with MS-DOS 3.3. I
notice in my /DOS directory four files: 4201.CPI, 5202.CPI,
EGA.CPI, and LCD.CPI. What are they, how can they be used, and
where can I find out more info about them?

CPI stands for "Code Page Information". Code-pages are IBM/DOS's way of supporting languages with glyphs (characters) that were not in the original definition of the IBM PC's character set. For instance, Danish, Norwegian, Arabic, Hebrew, most Eastern European languages, Portugese, etc. The character set documented in your DOS manual is CP (Code Page) 437 (USA standard English). This is also used by most of Western Europe. Code Page 850 was developed a couple of years ago and has the characters for all of Western Europe. As a USA/English user you should not have to worry about CPI files or code page information. Check your DOS manual under Code Page or chcp or NLSFUNC or COUNTRY= if you want more information.

Consult your DOS manual for details of how to use .CPI files with DISPLAY.SYS and PRINTER.SYS in the CONFIG.SYS file. Once you know what they are, it is unlikely you will want to (unless you use international characters not normally used in the USA). John Baird, Naval Ocean Systems Center, San Diego, CA ------- Definition of .CPI file: EXTENSION WHAT IT (USUALLY) MEANS CPI A file containing Code Page Information -------- Code page definition: A code page is a table used to translate a number in computer memory into a character (letter, number, or special symbol) displayed on the screen or printed on paper. Each key on the keyboard must also be translated into a number in computer memory so that it can later be displayed by using a code page. A default code page is "built in" to the computer and each peripheral. ------- .CPI related File Summary FILE NAME: WHAT IT DOES: CONFIG.SYS configuration file DISPLAY.SYS monitor configuration EGA.CPI code page information LCD.CPI code page information PRINTER.SYS printer configuration dddd.CPI code page information -------- The DEVICE line goes in the CONFIG.SYS file: DEVICE=[d:][pathname]filename[.ext] [options . . .] [d:][pathname]filename[.ext] is the device driver program. A device driver is a program used to control (drive) a peripheral device. DOS has a built-in set of drivers for the devices usually found on a computer. -------- Device drivers that can use .CPI files: WHAT IT IS WHAT IT DOES DISPLAY.SYS* support code page character display on enhanced graphics adapters and some others. PRINTER.SYS* supports code page character printing on Proprinter- compatible printers.
