The Accelerated Graphics Port standard was first released in 1997 as a method of dedicating bandwidth on the computer's motherboard, exclusively for graphics purposes. As the development of AGP advanced, the speed of the bus increased as well. AGP video cards only support the top speed available upon their release. While a 2x AGP card fits in an 8x slot, it still operates at 2x speed. You can slow down an AGP port in the computer's BIOS setup to make it compatible with older, slower cards.
Instructions
1. Power on, or restart the computer.
2. Press the hot key to enter the BIOS setup. The most common keys are "F1," "F2" and "Del." Refer to the motherboard owner's manual for details.
3. Navigate to the AGP settings with the arrow keys. This is usually located under "Advanced."
4. Toggle the AGP Speed setting to a slower value, such as 1x, 2x or 4x. Common toggle keys are "Enter" and the space bar.
5. Exit the BIOS, and save the settings. Most BIOS screens perform this function by pressing the "F10" key.
