Monochrome Adapter Check

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

Attribute Check

To check the display attributes of the adapter card, press 2 and then Enter. A series of messages appear showing examples of all the possible display attributes (normal intensity, high intensity, blinking, reverse, and underlining). Check the information that appears on your screen, and then respond to the prompt:

Is the display correct (Y/N)?

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