6 - RUN TESTS 1 THROUGH 5, 8: Performs tests 1 through 5 on a VGA
monitor and tests 1 through 5 plus 8 on SVGA and HiFunction monitors.
7 - SYNC TEST: Provides a test signal to allow voltage measurement at the
video connector.
8 - EXTENDED MODE TESTS: Shows a subset of the following character
modes: either 80x60 or 132x43; also 132x25. Also shows a subset of the
following graphic modes: 640x480x256, 800x600x256, and 1024x768x16.
