Utility (ICU) allows you to configure existing non-
Plug and Play ISA expansion cards for conflict-free
operation. Also, because the system BIOS is stored
in flash memory, it can be updated to support future
enhancements to the Plug and Play standard.
•
Wakeup On LAN capability, which, when enabled in
the System Setup program, allows the system to be
powered up from a server management console.
Wakeup On LAN capability also allows remote com-
puter setup, software downloading and installation,
file updates, and asset tracking after hours and on
weekends when LAN traffic is at a minimum.
NOTE: An optional Wakeup On LAN-capable net-
work card is required to use the Wakeup On LAN
feature.
•
Universal Serial Bus (USB) capability, which can
simplify connecting peripheral devices such as mice,
printers, and computer speakers. The USB connec-
tors on your computer's back panel, which are
enabled by default, provide a single connection
point for multiple USB-compliant devices. USB-
compliant devices can also be connected and
disconnected while the system is running.
•
A modular computer chassis with a minimum num-
ber of screws for easy disassembly and improved
serviceability.
The system board includes the following built-in
features:
•
Three 32-bit PCI expansion slots, two shared PCI
(32-bit)/ISA (16-bit) expansion slots, and two 16-bit
ISA expansion slots on a riser board.
•
A 64-bit accelerated graphics port (AGP) video sub-
system, which includes the ATI 3D Rage Pro super
video graphics array (SVGA) video controller. This
video subsystem contains 2 MB, expandable up to
4 MB, of synchronous graphics random-access
memory (SGRAM) video memory. Maximum reso-
lutions are 1600 x 1200 pixels with 256 colors
noninterlaced and 1024 x 768 pixels with 65,536
colors noninterlaced. In 800- x 600- and 640- x 480-
pixel resolutions, 16.7 million colors are available
for true-color graphics.
AGP provides a dedicated bus from the video sub-
system to the system chip set. AGP-based video

subsystems have two significant performance advan-
tages over PCI-based video subsystems:
— The AGP bus reduces bandwidth requirements
of the PCI bus, improving overall system
performance.
— The AGP bus allows a 3D 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 dis-
kette drive or tape drive.
•
Enhanced integrated drive electronics (EIDE) sup-
port. 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 ATA 33
hard-disk drives, EIDE CD-ROM drives, and EIDE
tape drives.
•
Two high-performance serial ports and one
bidirectional parallel port for connecting external
devices. The parallel port is fully Enhanced Capabil-
ities 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 3C916B media access controller
(MAC) Ethernet network interface controller (NIC).
The NIC is configured using software described in
Chapter 4, "Using Integrated Devices."
•
A 16-bit, integrated Plug and Play Crystal CS4236B
audio controller that provides all the sound functions
of the Sound Blaster Pro expansion card. For infor-
mation, see your online System User's Guide.
The following software is included with your Dell com-
puter system:
•
Utilities that safeguard your system and enhance the
operation of its hardware features, such as maximiz-
ing your monitor's resolution capabilities. For
information on these utilities, see your online System
User's Guide.
•
Video drivers for displaying many popular applica-
tion programs in high-resolution modes. For more
information on these utilities, see your online System
User's Guide.
