AGP Bus Your computer also has an integrated AGP Cirrus 5465 3-D SVGA (super video graphics array) bus. AGP is a state-of-the-art enhanced performance video bus for the integrated video controller, which provides a PC-like interface with performance extensions added specifically for video functions. Expansion with Adapters By installing optional adapters, you can expand the capabilities of your computer and take advantage of a variety of peripheral devices and applications. Your computer has a riser card for connecting adapters to the ISA or PCI bus. Examples of adapters that can be added to your computer include graphics, SCSI (small computer system interface), and NIC (network interface controller) adapters. High-Capacity Hard Disk Drives Some PC models come with a hard disk drive that has an enhanced integrated drive electronics (EIDE) bus-master interface. The EIDE drive plugs into one of two EIDE connectors located on the riser card in your computer. You can connect an additional hard disk drive to the ribbon cable already attached to the riser card, or you can purchase another cable and connect up to two hard disk drives or other IDE or EIDE devices to the second connector on the riser card. Notes: 1. In the desktop model, a maximum of three internal IDE or EIDE devices can be installed-limited by the number of available bays. 2. For models with an IBM factory-installed CD-ROM, two ribbon cables (for connecting IDE or EIDE devices) are shipped with your computer. CD-ROM Drive A CD-ROM drive is installed in some PC models. CD-ROM (compact disc read-only memory) technology offers quick access to enormous amounts of information. A compact disc can store more than 650 MB of data, such as the large files needed for audio, still and full-motion video, and still and animated graphics. A CD-ROM drive can play back or read from a CD, but it cannot write information on it. ECP/EPP Parallel Port Your PC has one 25-pin parallel port. The parallel port is most often used to communicate with a parallel printer, but it can also be used with other parallel Chapter 1. Your IBM Personal Computer 5
