Keyboard - (KEYBD.EXE)
The Keyboard test consists of two types of tests: a full keyboard test, and a short keyboard test.
For the full test, press the keys from left to right, top to bottom starting with Esc. For the short
test, start with Pause/Break key and go clockwise around the outside of the keyboard and finish
at the Scroll Lock key. Both tests skip the Fn key.
A high-pitched beep after a key press means it was the correct key and a low-pitched beep
means it was incorrect. After an incorrect key is entered (low-pitched beep), the test allows four
more attempts at entering the correct key.
The “Display Mode” of the keyboard test will display the number of the key as each key is
pressed. The keys may be entered in any order. This mode is entered by pressing Esc during
the test (as long as Esc is not the next key in the key sequence to be tested). Pressing Esc
again exits display mode and resumes the keyboard test.
The DIAG.INI must be modified in order to invoke the short test within the user interface. Use
the corresponding parameter explained in the below DOS Parameters table.
