Different characters appear on screen due to incorrect COUNTRY command setting.
Cause:
Either CONFIG.SYS contains the COUNTRY command with an incorrect country setting, or someone temporarily changed the keyboard setting with the KEYB command.
Solution:
Edit CONFIG.SYS and change or remove the COUNTRY command, or enter the KEYB command at the DOS prompt.
Do one or both of the following:
1) Edit CONFIG.SYS:
a) Check for a command line matching the following:
COUNTRY=<country>
(where <country> represents a country or foreign language).
b) If this exists, do one of the following:
1] If the desired language is English, delete this line.
2] If the desired language differs from what is there, change the country to desired country/language (see DOS manual for list of countries).
2) Enter the following command at the DOS prompt to return to a United States English keyboard configuration:
KEYB US
