Technical Field: The present invention provides an improved data processing system, and more particularly, a method and apparatus for managing a data processing system. Still more particularly, a method and apparatus for configuring a display device in a data processing system. 2. Description of related technology: In a data processing system, a monitor or display device is used to present information to a user 'and to help the user interact with the data processing system. There are many different ways to classify display devices. The most basic is color capability, which separates display devices into three categories: single color, gray scale, and color ° Single color display devices actually display two colors, one for the background and one for the foreground. Colors can be black and white 'green and black, or amber and black. A gray scale display device is a special type of monochrome display device capable of displaying different shades of gray. The color display device can display from about 16 to more than one million different colors. Color display devices are sometimes called RGB monitors because they accept three separate signals-red, green, and blue. The resolution of a display device indicates how dense those pixels are gathered. In general, the more ‘pixels’ (usually expressed as female 忖 dots), the sharper the image. Most modern display devices can display 1024 by 768 pixels, which is the Super Video Graphics Adapter (SVGA) standard. Some high-end models can display 1280 by 1024, or even 1600 by 1200. In addition, most display devices either support a fixed update rate or may be multi-scanned, where the update rate is adjusted from the signal sent to the display device's adapter. Update rate is screen update per second (redraw) -4- This paper size is applicable to China National Standard (CNS) A4 specification (210X 297 mm)

This step may include connecting a new monitor or reconnecting an existing monitor. The display adapter detects the connection of the monitor to the data processing system (step 402). When detecting the cable connection, the display adapter generates a device driver private interrupt to trigger a device driver interrupt handler to execute the monitor configuration (step 404) ^ device driver interrupt processing prepares to receive interrupt (step 406) ) And execute a monitor configuration program to reconfigure the data processing system to use the monitor (step 408). In reconfiguring the data processing system, the adapter may be instructed to set various features in the monitor, such as resolution and update rate. At this time, the user judges whether the screen is viewable (step 410). If the screen is viewable, the process ends. Otherwise, the procedure returns to step 4GG, where the user reconnects to the available monitor or connects a new monitor to the data processing system. This procedure is used for maintenance. When a user connects an unsupported monitor, the user does not need to restart the system, because the configuration procedure in the second step obtains information from the monitor and configures the data processing system to use the monitor.

By storing this information, the user can choose a different resolution or update rate later. If the user has selected a different resolution or update rate for the display device, the new resolution and update rate will remain through the system configuration. The resolution and update rate selected by this user are reset to default values during system configuration only if they are not supported by the current EDID. If the EDID is not read from the monitor, the monitor will then end with the program to set the resolution and update rate that the user has previously selected, or a predefined resolution and update rate (step 512). ). The resolution and update rate are selected so that most monitors will provide a visual display. For example, a resolution of 128 × 1 024, which is one of the 60 Hz update rates, may be used as a predefined resolution and update rate. Step M] The prosthetic foot monitor cannot send an EDID or provide an EDID. Of course, the failure to read the EDID of a monitor may be due to a monitor not being connected to the data processing system. In this case, the monitor should be reconnected. In addition, if the monitor does not support EDID and the predefined resolution and update rate do not provide a viewable screen, the monitor should be reconnected or replaced, and the system should be restarted.
