Diagnostic Video Tests: Dell Latitude CP
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 correctly; otherwise, type n. Table B-1 indicates the color in each
of the rows and columns.
