1-2 Dell OptiPlex GX1 and GX1p Mini Tower Managed PC Systems Reference and Installation Guide
A secondary cache of 512 KB of static random-access memory (SRAM) included
within the single-edge contact (SEC) cartridge, which also contains the
microprocessor.
System memory that can be increased up to 384 megabytes (MB) by installing
64- or 128-MB synchronous dynamic random-access memory (SDRAM) dual in-
line memory modules (DIMMs) in the three DIMM sockets on the system board.
The system also supports both error checking and correction (ECC) and nonparity
DIMMs. See “Adding Memory” in Chapter 6 for details.
Self-Monitoring and Analysis Reporting Technology II (SMART II) support, which
warns you at system start-up if your hard-disk drive has become unreliable. To
take advantage of this technology, you must have a SMART II-compliant hard-disk
drive in your computer. All hard-disk drives shipped with OptiPlex GX1 systems
are SMART II-compliant.
A basic input/output system (BIOS), which resides in flash memory and can be
upgraded by diskette, or remotely over a network, if required.
Full compliance with PCI specification 2.2.
Full Plug and Play version 1.0a capability, which greatly simplifies the installation
of expansion cards. Plug and Play support included in the system BIOS allows
you to install Plug and Play expansion cards without setting jumpers or switches
or performing other configuration tasks. The ISA Configuration 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 computer setup, software down-
loading and installation, file updates, and asset tracking after hours and on
weekends when network traffic is at a minimum. For more information, refer to
Chapter 2, “Using the System Setup Program.”
Universal Serial Bus (USB) capability, which can simplify connecting peripheral
devices such as mice, printers, and computer speakers. The USB connectors on
your computer’s back panel, which are enabled by default, provide a single con-
nection 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 number of screws for easy dis-
assembly 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 subsystem, which includes the ATI
3D Rage Pro super video graphics array (SVGA) video controller. On the Dell Opti-
Plex GX1, this video subsystem contains 4MB (upgradable to 8 MB) of
