1 - VGA TEST: Verifies the video portion of the system board.
2 - DISPLAY ATTRIBUTES: Shows the following character attributes:
normal and high intensity, reverse video, blinking, non-monitor, and 16

3 - CHARACTER TESTS: Shows the following character modes: 40x25,
80x25, 80x30, and 256 ASCII characters.
4 - GRAPHICS TESTS: Displays various patterns to test the monitor
graphics modes.
5 - SCREEN PAGING: Tests the video-addressing circuitry.
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.
Note: This test is only available for SVGA Tri-Synch and Multi-Scanning
monitors. Availability also depends on the amount of video DRAM present.
