Epson 386SX - Manual (Page 203)

Before checking the operation of the keys, you must identify
your keyboard layout so the test is appropriate for the keys on
your keyboard. A display appears, asking you to identify the
shape of your
Enter key. Choose the shape that matches the
one on your keyboard, then press Enter.
The program displays your keyboard layout on the screen.
When you press a key on the keyboard, an asterisk appears at
the corresponding location on the keyboard
layout.
If you hold
a key down, the asterisk begins to blink. If an asterisk does not
appear at the correct location, there is a problem with your
keyboard. Test each key.
You see these messages on the screen:
Press ESC followed by ENTER to exit.
Press END followed by ENTER if screen
and keyboard do not match.
If all the keys function correctly and match the characters
displayed, press
E
SC
and then Enter.
If all the keys function, but the characters displayed do not
match the keys, press
E
SC
and then Enter. Then reselect the
keyboard test from the Device List, and check that you selected
the correct keyboard layout. You can find diagrams of all the
international keyboard layouts in the MS-DOS Reference
Manual.
If any key is incorrect, press End and Enter. Make a copy of the
error code and message, or print them out, and contact your
Epson dealer or service center.
