IDE — integrated device electronics — An interface for mass storage devices in which the controller is integrated into the hard drive or CD drive. IEEE 1394 — Institute of Electrical and Electronics Engineers, Inc.
Mini PCI — A standard for integrated peripheral devices with an emphasis on communications such as modems and NICs. A Mini PCI card is a small external card that is functionally equivalent to a standard PCI expansion card. Mini-Card — A small card designed for integrated peripherals, such as communication NICs. The Mini-Card is functionally equivalent to a standard PCI expansion card. modem — A device that allows your computer to communicate with other computers over analog telephone lines.
RAM — random-access memory — The primary temporary storage area for program instructions and data. Any information stored in RAM is lost when you shut down your computer. readme file — A text file included with a software package or hardware product. Typically, readme files provide installation information and describe new product enhancements or corrections that have not yet been documented. read-only — Data and/or files you can view but cannot edit or delete.

Addressing Memory With 4-GB or Greater Configurations (32-bit Operating Systems Only) This computer supports a maximum of 8 GB of memory. Current 32-bit operating systems, such as Microsoft® Windows® XP, can use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than that installed. Certain components within the computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.
Installing Memory CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide. NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis. NOTE: Memory purchased from Dell is covered under your computer warranty. 1.
