ext Mode Color Test

The Text Mode Color Test contains three subtests that
check the video subsystem’s ability to present color in
text modes. The following subsections describe these
subtests.

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 cor-

rectly; otherwise, type

n

. Table B-1 indicates the color in

each of the rows and columns.
