diagnostic tests can be performed. These tests use 18 test patterns to fill the video buffer, testing
your graphics acceleration and text output

the graphics acceleration and testing the text output. You can follow the tests being performed
on the monitor. This test can be cancelled at any time by pressing <Esc> on the keyboard.
• Video Memory: Tests the video memory by filling the video buffer with 18 test patterns, one
