Introduction 1-3
AGP provides a dedicated bus from the video subsystem to the system chip set.
AGP-based video subsystems have two significant performance advantages over
PCI-based video subsystems:
— The AGP bus reduces bandwidth requirements of the PCI bus, improving
overall system performance.
— The AGP bus allows a video subsystem to execute directly from main
memory.
‡
A diskette/tape drive interface, which supports a 3.5-inch diskette drive and,
optionally, a second diskette drive or tape drive.
‡
Enhanced integrated drive electronics (EIDE) support. The primary and secondary
interface are both located on the PCI bus to provide faster data throughput. Each
interface supports high-capacity EIDE drives, as well as devices such as
advanced technology attachment (ATA) 33 hard-disk drives, EIDE CD-ROM drives,
and EIDE tape drives.
‡
Two high-performance serial ports and one bidirectional parallel port for connect-
ing external devices. The parallel port is fully Enhanced Capabilities Port (ECP)
compliant.
‡
A Personal System/2 (PS/2)-style keyboard port and a PS/2-compatible mouse
port.
