ISA bus Your computer has an ISA (industry standard architecture) bus, which is a widely used I/O (input/output) bus. The ISA bus is popular because so many adapters and devices have been designed and marketed for it. Graphics subsystem Your computer has a high performance accelerated graphics port (AGP) graphics subsystem that provides fast access to system memory for video functions. Some models have an integrated S3 Trio3D graphics subsystem. This subsystem provides a connector on the rear of the computer for attaching a monitor. Your computer provides SGRAM (synchronous graphics RAM) video memory to further improve video performance. Note: To view the amount of video memory in your computer, see "Viewing the system summary" on page 66. For information on the refresh rates supported for the various resolutions available with S3 Trio3D video, see "Using video features" on page 46. If you decide to change the video capabilities of your computer and your computer has an AGP connector, you can use the AGP connector on the system board for installing a future AGP adapter. This connection can support bus speeds up to 133 MHz. Instructions for installing an AGP adapter are in Installing Options in Your Personal Computer. Some models might have a different graphics adapter, such as the Matrox™ G200, Intense™ 3D Wildcat 4000, or the IBM Fire GL1. The systems with these new graphics adapters do not have a video connector on the system board. The video cable must be connected to the adapter itself. For information about obtaining the latest device drivers for your graphics adapter, see Chapter 8, "Getting help, service, and information" on page 141. Audio subsystem Some models have an integrated audio controller that provides all the digital audio and analog mixing functions required for recording and playing high-quality sound on your computer. This audio controller supports Sound Blaster Pro, Adlib, and Microsoft Windows Sound System applications. Chapter 1. Your IBM personal computer 5
