Overview 1-13
System Memory
The system supports up to 512 MB of high-speed non-ECC or ECC RDRAM memory in two
RIMM sockets on the system board. Supported are 184-pin, PC800-MHz modules in
64-, 128-, and 256-MB unbuffered configurations.
The RIMM modules can be installed in one or two sockets and can vary in size between sockets.
If only one RIMM module is installed, a continuity module must be installed in the empty
socket.
Diskette Drive
A single diskette drive is supported in the system. The installed 1.44-MB 3 1/2-inch diskette
drive is connected by a ribbon cable with two connectors. The diskette drive cable plugs directly
into the system board. There are no switches or jumpers that need to be set and the diskette drive
is terminated.
Diskette drive specifications are given in Section 9, “Specifications.”
Hard Drive
All systems ship with one internal 3 1/2-inch EIDE hard installed inside the system, under the
CD-ROM drive. Drives are available in 10-GB or higher Ultra DMA/66 models.
An Ultra DMA/66 cable connects the hard drive to the primary IDE channel on the system
board. The drive is connected as the master device on the primary channel.
Hard drive jumper settings are given in Section 2, “System Configuration.” The location of the
primary IDE connector on the system board is shown in Section 4, “System Boards.” Hard drive
specifications are given in Section 9, “Specifications.”
AGP Video Board
Systems ship with an AGP video board. The board has a 4x nVidia Vanta™ 3D graphics
processor, 8 MB of video memory, and a VGA connector. The processor supports the AGP 4X
bus, 3D graphics, and 2D graphics. It also supports video, software, and DVD playback. The
system can be upgraded with an optional 32-MB 4x nVidia TnT2 Pro AGP video board.
Connect a VGA compatible monitor to the VGA connector on the AGP video board.
Power Supply
The 235-watt power supply is mounted inside the system unit. It supplies power to the system
board, option boards, diskette drive, hard drives, CD-ROM or other drives, keyboard, mouse,
and other internal options. A fan inside the power supply provides system cooling.
Power supply connector locations on the system board are given in Section 4, “System Board.”
Power supply specifications are given in Section 9, “Specifications.”
Keyboard
The PS/2-compatible ergodynamic keyboard is standard equipment for the system. The
keyboard provides a numeric keypad, separate cursor control keys, 12 function keys, and is
capable of up to 48 functions. Key status lamps on the keyboard include Num (Numeric) Lock,
Caps (Capital) Lock, and Scroll Lock.
The keyboard’s six-pin connector plugs into the back of the system. Keyboard specifications are
