Main memory for the OptiPlex GX1 and OptiPlex NX1 systems ranges from a
minimum of 32 MB to a maximum of 384 MB. Main memory for the OptiPlex
GX1p system ranges from a minimum of 128 MB to a maximum of 384 MB. All
main memory for the OptiPlex GX1 and OptiPlex NX1 systems is implemented
using high-speed error checking and correction (ECC) and non-ECC DIMMs. All
main memory for the OptiPlex GX1p system is implemented using high-speed
ECC DIMMs. One to three DIMMs, ranging in memory capacity sizes from 32
to 128 MB, may be used to provide a maximum memory capacity of 384 MB.

The system BIOS is implemented in flash ROM, which allows for easy BIOS
upgrades using diskette files or files downloaded from Dell’s home page on
the World Wide Web (
www.dell.com
). The BIOS also incorporates the POST
diagnostics, which tests the system each time the system is started.

The EIDE subsystem implemented on the system board provides two Mode-4,
DMA bus-mastered EIDE interfaces, each of which can support up to two
EIDE devices (for example, CD-ROM drive, hard-disk drive, and so on). The
EIDE controller attaches to the high-speed PCI local bus.
The primary EIDE interface (IDE1) provides support for up to two high-
performance EIDE devices. The computer’s boot drive should be connected
to the primary EIDE interface.
The secondary EIDE interface (IDE2) also provides support for up to two high-
performance EIDE devices, typically EIDE tape drives or CD-ROM drives.
NOTES: Any externally accessible drive bays at the front of the computer are
normally used for diskette, CD-ROM, and/or tape drives. Hard-disk drives
should be installed in the internal hard-disk drive positions described in “Hard-
Disk Drive Service Information” found later in this chapter.
The OptiPlex NX1 system supports only one hard-disk drive and optionally one
external diskette drive for running the diskette-based diagnostics as described
in Chapter 2,“Basic Troubleshooting”.

As a standard feature, OptiPlex GX1/GX1p and OptiPlex NX1 systems are
equipped with Self-Monitoring and Analysis Reporting Technology (SMART),
which warns you at system start-up if your hard-disk drive has become
unreliable. This warning occurs only if you use hard-disk drives with SMART
technology.
