The Video Memory Test verifies the integrity of the video memory either on the
system board or on a video expansion card. As the test runs, it describes which
64-kilobyte (KB) block of video memory is being tested. When a test is complete, a
message indicates whether the video memory has passed or failed the test. This test
does not require any interaction on your part.

The Text Mode Character Test consists of a group of subtests that display printable
characters and character attributes. The subtests check character quality and the mon-
itor’s ability to display the characters correctly on its screen. A prompt at the bottom
of each screen asks the user to decide whether the display is satisfactory and to
respond by typing
\
or
Q
.
If you respond affirmatively to each subtest, the Text Mode Character Test passes. A
negative response to any subtest causes the test to fail.
The following subsections describe the subtests of the Text Mode Character Test in
the order in which they appear.
