The Text Mode Color Test contains three subtests that
check the video subsystem’s ability to present color in
text modes. The following subsections describ e these
subtests.
NOTE: These subtests are valid for color monitors only.

Color Attributes Subtest (80 x 25)

The 80-column x 25-line color attributes subtest displays
a pattern of 16 rows and 16 columns in 80-column by
25-line text mode. Each row has a hexadecimal number
in a unique foreground color and each column has a
unique background color. Where the same foreground
and background color intersect, the hexadecimal number
is not visible. Type y if each character is displayed
correctly; otherwise, type n. Table B-1 indicates the color
in each of the rows and columns.
