Baseline AGP provides a dedicated bus from the video subsystem to the system chip set. The AGP bus reduces bandwidth requirements of the PCI bus, improv- ing overall system performance.

‡ 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.

‡ An optional integrated, 10/100-megabit-per-second (Mbps) 3Com® PCI 3C905B-TX Ethernet network interface controller (NIC). The NIC is configured using software described in Chapter 4, “Using Integrated Devices.”

Introduction 1-3

random-access memory (SGRAM) video memory. Maximum resolutions are 1600 x 1200 with 256 colors noninterlaced and 1280 x 1024 with 65,536 colors noninterlaced. In 1024 x 768, 800 x 600, and 640 x 480 resolutions, 16.7 million colors are available for true-color graphics using a 32-bits per pixel (bpp) format. True-color provides higher performance, but uses more graphics memory. Table 1-1 displays the video memory requirements for the Microsoft Windows® 95 and Windows NT 4.0 operating systems.

NOTE: These resolutions and refresh rates may not be available on all monitors.
