[02. KEYBOARD TEST]
The Keyboard Test contains three subtests that test the computer's
keyboard and mouse actions.
[01. Pressed key display]
When you execute this subtest, the keyboard layout is drawn
on the display. When any key is pressed, the corresponding key
appears on the display. Pressing and holding a key enables the
auto-repeat function which causes the key's displayed
character to blink.
Before executing the test, select Keyboard Type in the test
parameters.
[02. Keyboard LED on]
The system flashes the Num Lock, Caps Lock, and Scroll
Lock LEDs.
[03. PS/2 Mouse]
This subtest checks whether a PS/2 mouse is connected or not.
During the test, no message appears on the screen.
