Color Graphics Adapter Check

To check the color graphics adapter, press 1 and then Enter. The computer checks the video RAM (display memory) on the display adapter by writing test data to memory, and then reading it back and comparing it to the written data. It also tests the video enable signal of the display controller chip.

Attribute Check

To check the display attributes of the color graphics adapter card, press 2 and Enter. Several messages are displayed showing examples of all the possible display attributes and colors. Check the information displayed on your screen, and respond to the prompt:

Is the display correct (Y/N)?

Press Y and then Enter if the display is correct. If the colors are not correct, adjust the controls on your display monitor. If they are still incorrect, press N and Enter.

Contact your Customer Care Center if you have any monitor problems.
