These systems incorporate a high-performance Peripheral Component Interconnect (PCI) design, allowing a wide range of initial configurations and upgrade possibilities. This chapter provides information about the following topics: • Major hardware and software features of your computer • Available upgrades for your computer • Theft-deterrent features to protect your computer Hardware Features Your Dell computer offers the following hardware features: • An Intel Socket 370 Pentium III processor with Streaming SIMD Extensions or a Celeron processor with MMX technology. The System Information screen in the system setup program lists the speed of your system's processor. For information on accessing this application program, see Appendix B, "System Setup Program." • Minimum memory configuration of 64 megabytes (MB) synchronous dynamic random-access memory (SDRAM). You can increase memory up to 512 MB by installing 32-, 64-, 128-, or 256-MB SDRAM dual in-line memory modules (DIMMs) in the two DIMM sockets on the system board. NOTE: The system memory value reported by the operating system is 1 or 2 MB less than the memory installed because that memory is reserved for video functions. For example, if the computer has 64 MB of system memory, the operating system may report 62 or 63 MB. support.dell.com Introduction 1-1
