Diagnostic Video Tests: Dell™ PowerEdge™
2300 Systems Installation and Troubleshooting Guide
The Video
Test Group of the system diagnostics consists of the following eight tests, each of which
verifies a particular video function or group of functions:
- Video Memory Test -- Checks the integrity of
characters generated from data in the video memory .
- Video Hardware Test -- Checks the functions
of the cursor register and the horizontal and vertical retrace bit registers .
- Text Mode Character Test -- Checks the video
subsystem's ability to present text mode data.
- Text Mode Color Test -- Checks the video
subsystem's ability to present color in text modes.
- Text Mode Pages Test -- Checks the video
subsystem's ability to map and present all available video text pages on the monitor
screen, one page at a time .
- Graphics Mode Test -- Checks the video
subsystem's ability to present graphics mode data and colors.
- Color Palettes Test -- Checks the video
subsystem's ability to display all available colors .
- Solid Colors Test -- Checks the video
subsystem's ability to show screens full of solid colors. Allows you to check for missing
color subpixels.
All of these
tests, except the Video Memory Test and the Video Hardware Test, are interactive. These
interactive tests display images on the monitor screen and require the user to respond
with the following steps:
1. Examine
a displayed image for correctness.
2. If an
image is correct, type y.
3. If an
image is incorrect, type n.
The following
sections describe each of the tests in the Video Test Group.
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 Video
Hardware Test verifies the operation of the cursor registers and the horizontal and
vertical retrace bit registers. When a test is complete, a message indicates whether these
registers have 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 monitor'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 y or n.
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.
Character Attributes Subtest (80 x 25)
The 80-column
x 25-line character attributes subtest displays four lines of text that demonstrate
normal-intensity video, reverse video, intensified video, and blinking video.
Character Set Subtest (80 x 25)
The 80-column
x 25-line character set subtest displays all 256 characters in the American Standard Code
for Information Interchange (ASCII) character set in 80-column by 25-line text mode.
Character Attributes Subtest (40 x 25)
The 40-column
x 25-line character attributes subtest displays four lines of text in
40-column by 25-line (double-wide) text mode that demonstrate normal-intensity video,
reverse video, intensified video, and blinking video.
Character Set Subtest (40 x 25)
The
40-column x 25-line character set subtest displays all 256 characters in the ASCII
character set in 40-column by 25-line (double-wide) text mode.
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.
 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 1 indicates the color in each of the
rows and columns.

Color Attributes Subtest (40 x 25)
The 40-column
x 25-line color attributes subtest is the same as the previous subtest except that the
characters are displayed in 40-column by 25-line (double-wide) text mode. Type y if each
character is displayed correctly; otherwise, type n.
Color Bars Subtest
The color
bars subtest displays 16 bars in different colors with background intensity enabled. Under
each bar is the name of the color that should be displayed. Type y if each color bar is
displayed correctly; otherwise, type n.
The Text Mode
Pages Test checks the video subsystem's ability to map and present all available video
pages on the monitor screen, one page at a time. The test displays eight successive
screens, the first of which contains 21 lines of 77 zeros. The remaining seven
screens are identical to the first, except that each screen substitutes a different
numeral (1 through 7) for the zeros.
Type y if all the rows of numbers on each screen are displayed correctly;
otherwise, type n .
The Graphics
Mode Test checks the video subsystem's ability to present graphics mode data and colors.
Each screen in this test allows you to check some aspect of graphics mode data and colors.
The following sub�sections describe Graphics Mode Test screens in the order in which they
appear.
NOTE: Some of the following tests may
not appear if your system does not support the video mode being tested.
320 x 200
Graphics Mode Screens
The Graphics
Mode Test displays two successive 320- x 200-pixel graphics mode screens: The first screen
displays three pyramids in red, green, and yellow; the second screen displays three
pyramids in magenta, cyan, and white. Type y if all the pyramids are the correct colors;
otherwise, type n.
640 x 200 Black/White Graphics Mode Screen
The 640- x
200-pixel black/white graphics mode screen displays a black rectangle and a white
rectangle on a gray background. Type y if the boxes are displayed
correctly; otherwise, type n .

colors located in various positions on the screen. Type y if all the squares appear to be
correct; otherwise, type n.
The Color
Palettes Test checks the video subsystem's ability to display all available colors. The
test displays two screens that allow you to check the quality of different shades of the
basic colors and to test the monitor's ability to vary the intensity of these colors.
The first
screen contains four sets of 64 squares, one for gray and one for each of the three basic
colors (red, green, and blue). Each square contains a different shade of its associated
color, ranging from very light to very dark. Type y if all the squares are the correct
colors; otherwise type n.
The second
screen is the red/green/blue (RGB) color combination screen. This screen allows you to
test the monitor's ability to increase or decrease the intensity of the three basic
colors.
The RGB color
combination screen displays an RGB box in the top center of the screen with individual
red, green, and blue boxes beneath it. Underneath the individual color boxes are three
lines that show the intensity of each color. Type r, g, or b to adjust the intensity of
the corresponding color; then press the right-arrow key to increase the color intensity,
or press the left-arrow key to decrease the intensity. The RGB box should be able to
display 262,144 different colors when you adjust the intensity levels of red, green, and
blue. Type y if all the squares are the correct colors; otherwise type n.
The Solid
Colors Test checks whether the video subsystem is displaying the correct colors. This test
also lets you check for missing pixels. When this test is running, four screens appear
sequentially--a red screen, a green screen, a blue screen, and a white screen. Check each
screen for missing pixels, and verify that the correct color is being displayed.
When the
test is complete, a message asks if you are satisfied with the quality of the colors. Type
y if all the pixels were present and if the correct colors were displayed; otherwise, type
n .
