Components

This section provides an overview of the NEC Power Mate VT 300i Series microtower computer system configurations. The sect ion high lights system hardware features, co mputer fro nt , back, and inside features, and syst em security features. Also included are brief descriptions of the major components comprising the system.

Configurations

NEC PowerMate VT 300i Series computer systems are built-to-order systems for commercial o ffices. T he systems feature an Intel Celero n, Pentium II, or

Pentium III processor, two dual inline memory module (DIMM) sockets, synchronous dynamic random access memory (SDRAM), and a plug and play input/output (I/O) controller.

The system also featur es t wo universal ser ia l bu s (USB) ports, two serial ports, and a parallel port. Ultra direct memory access (DMA), r emote wakeup (“WakeOn LAN”), accelerated graphics port (AGP), and power management are supported.

Build choice s inclu de intell igent device electronics (IDE ) hard drives ranging from 4.3 gigabyte (GB) to 12.9 GB. System memory is provided in 32-megabyte (MB) (minimum), 64-MB, or 128-MB DIMM modules. Memory configurations range from 32 MB to 256 MB.

Additional build choices include fax/modem, sound, video, and peripheral devices such as CD-ROM drives.

The following figure shows the components comprising the PowerMate VT 300i Series system (the monitor and speakers ar e optional).

The following paragraphs list the system int err upts (IRQs), parallel addr esses and interrupts, and serial addresses and interrupts. Section 4, “System Board,” includes information on system resour ces ( memory ma p , I/O addresses, and DMA settings).

System Interrupts

The system has 16 IRQs (IRQ 0 through 15) assigned t o different devices (for example, printer, mode m, keyboard, mouse). Initial IRQ settings are assigned at the factory, with settings dependent on the installed device(s). Several IRQs are unassigned for the installation of add-on devices. See “BIOS Setup” utilit y in this section for infor mat ion on using the ut ility to ass ign or change the interrupts.

The following table lists the IRQ settings. Note that assignments 0 through 15 are in order of decreasing priority.
