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 highperformance 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 highperformance 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 "HardDisk 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. 1-4
