Introduction 1-3
A modular computer chassis with a minimum number of screws for easy dis-
assembly and improved serviceability.
A high-speed, high-resolution AGP or PCI graphics adapter. (Documentation from
the graphics adapter manufacturer is included with the system.) AGP greatly
improves graphics performance by providing a dedicated bus for a faster interface
between the video subsystem and system memory. AGP also allows conven-
tional memory to be used for video-related tasks.
The system board includes the following integrated features:
Five 32-bit PCI expansion slots, including one that is a shared PCI (32-bit)/ISA
(16-bit) expansion slot and one that has an extension for a redundant array of
inexpensive disks (RAID) upgrade.
One AGP expansion slot.
A diskette drive interface, which supports a 3.5-inch slimline diskette drive.
Two ATA-33 channels that support up to four EIDE devices. The primary and
secondary channels utilize the PCI bus to provide faster data throughput. Each
channel supports extremely high-capacity EIDE drives, as well as devices such as
EIDE CD-ROM drives and EIDE tape drives.
SCSI support using two integrated SCSI channels.
— The primary channel provides Ultra2/Wide low voltage differential (LVD)
(80-MB/second) support for high-performance SCSI hard-disk drives and an
optional RAID subsystem.
— The secondary channel provides support for external Ultra/Wide
(40-MB/second) SCSI devices such as scanners and for internal narrow
SCSI devices such as CD-ROM drives, tape drives, and optical drives.
Two high-performance serial ports and one bidirectional parallel port for connect-
ing external devices.
A Personal System/2 (PS/2)-style keyboard port and a PS/2-compatible mouse
port.
An integrated 10/100-megabit-per-second (Mbps) 3Com
®
PCI 3C905b-TX Ether-
net network interface controller (NIC) with Wakeup On LAN support. The NIC is
configured using software described in Chapter 5, “Using the Network Interface
Controller.”
The following software is included with your Dell computer system:
Utilities that safeguard the system and enhance the operation of its hardware
features; for example, the AutoShutdown service lets you perform an orderly
shutdown with a single touch of the power button. For more information on these
utilities, see Chapter 2, “Using the Software Support Utilities.”
