Chapter 2 System Overview

2.4.4 SYSTEM MEMORY

These systems use the NVidia IGP component that supports DDR SDRAM. The system board provides two sockets that accept industry-standard unbuffered DDR DIMMs.

The D315 system uses the IGP-64 controller that supports 64-bit PC2100 DDR memory and a maximum of 1 gigabyte of memory.

The d325 system uses the IGP-128 controller supporting 128-bit (when two DIMMs are installed) PC2700 DDR memory and a maximum of 2 gigabytes of memory.

2.4.5 MASS STORAGE

All models include a 3.5 inch 1.44-MB diskette drive installed as drive A. Most models also include a CD-ROM and a 20- to 80-GB hard drive. Standard hard drives feature Drive Protection System (DPS) support. All systems provide two (one primary, one secondary) PCI bus-mastering Enhanced IDE (EIDE) controllers integrated into the chipset. Each controller provides UATA/100 support for two drives for a total of four IDE devices, although the form factor will determine the actual number of drive spaces available.

2.4.6 SERIAL AND PARALLEL INTERFACES

This system includes one serial port and a parallel port accessible at the rear of the chassis. The serial interface is RS-232-C/16550-compatible and supports standard baud rates up to 115,200 as well as two high-speed baud rates of 230K and 460K, and utilizes a DB-9 connector. The parallel interface is Enhanced Parallel Port (EPP1.9) and Enhanced Capability Port (ECP) compatible, and supports bi-directional data transfers through a DB-25 connector.

2.4.7 UNIVERSAL SERIAL BUS INTERFACE

The Universal Serial Bus (USB) interface supports hot plugging/unplugging (Plug ’n Play) functionality for six USB ports. Two ports are accessible at the front of the unit and four ports are available at the rear of the chassis. The D315 model provides USB 1.1 support while the d325 model provides 2.0 support.
