Dell OptiPlex G1 - Manual (Page 23)

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.”
