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.
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.”
