Processor and Secondary Cache 

The system uses an Intel Pentium processor with an internal clock speed of 166 MHz, 

200 MHz or 233 MHz. Some processors use the Intel MMX technology. 

The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed to 

optimize multitasking operating systems. The 64-bit registers and data paths support 64-bit 

addresses and data types.


To use the Pentium processor’s power, the system features an optimized 64-bit memory 

interface and 512 KB of secondary write-back cache soldered onto the system board. 

The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386, 

Intel486, Pentium, and Pentium Pro processors. The Pentium processor is mounted in a 

socket-7 zero insertion force (ZIF) socket. The socket provides an upgrade path to the 

Pentium Overdrive processor. 

System BIOS 

The system BIOS is from Intel, based on Phoenix Technologies Limited (PTL) Release 6.0. 

This ISA- and PCI-compatible BIOS is contained in a flash memory device on the system 

board. The BIOS provides the Power-On Self-Test (POST), the system Setup program, a 

PCI and IDE auto-configuration utility, and BIOS recovery code. 

The system BIOS is always shadowed. Shadowing allows any BIOS routine to be executed 

from fast 32-bit DRAM on the system board, instead of from the slower 8-bit flash device. 

NEC’s Flash ROM allows fast, economical BIOS upgrades. The Flash ROM is a 

reprogrammable EPROM containing both the system and video BIOS. Using the Flash 

ROM to change the ROM BIOS provides the following advantages: 

� the BIOS upgrade is performed quickly and easily 

� the expense of replacing ROM BIOS chips is eliminated, so system maintenance 

costs are reduced 

� there is less chance of inadvertently damaging the system board than when 

physically replacing ROMs 

� new technology can be incorporated while maintaining corporate standards 

� network administrators can exercise company-wide control of BIOS revisions. 

The BIOS programs execute the Power-On Self-Test, initialize processor controllers, and 

interact with the display, diskette drives, hard disk drives, communication devices, and 

peripherals. The system BIOS also contains the Setup utility. The POST copies the ROM 

BIOS into RAM (shadowing) for maximum performance. 

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Update 

utility, without having to physically remove the ROM (see Section 2 for further information 

on the BIOS Update utility). The Flash ROM supports the reprogramming of the system 

BIOS and the video BIOS.

The system comes with between 16 MB and 256 MB of SDRAM installed in dual in-line 

memory module DIMM sockets on the system board. 

The memory configuration consists of two sockets. The DIMM memory sockets accept 

168-pin, 64-bit (non-parity) 8-, 16-, 32-, 64-, and 128-MB DIMMs. Table 1-5 lists the 

supported DIMMs.

8 MB CAS Latency 2 SDRAM 1-Mbit x 64-bit 16 Mbit 




128 MB CAS Latency 2 SDRAM 16-Mbit x 64-bit 64 Mbit


Memory upgrades are easy with DIMM modules. Advantages of using DIMMs include: 

� DIMMs do not need to be installed in pairs on the system board 

� DIMMs of different memory types and sizes can be installed on the same board 

� no switches or jumpers need to be set if the memory is changed 

� system BIOS automatically detects the DIMMs. 

See “Checking the Memory in the System” in Section 3 for the valid DIMM configurations. 

Hardware Monitor 

The National Semiconductor Heceta LM78 chip provides economical instrumentation 

capabilities for reduced cost of PC ownership when the system is used with the LANDesk 

Client Manager. This single-chip ASIC features: 

� integrated ambient temperature sensor 

� power supply voltage monitoring to detect excessively high or low voltage levels 

� registers for storing POST hardware test results and error codes 

� remote reset capabilities from a remote peer or server through LANDesk Client 

Manager v.3.0 

When ranges for temperature or voltage are exceeded, an interrupt is activated. The 

hardware monitor component connects to the ISA bus as a 8-bit I/O mapped device. 

Interrupt Controller 

The interrupt controller operates as an interrupt manager for the entire system environment. 

The controller: 

� accepts requests from peripherals 

� issues interrupt requests to the processor 

� resolves interrupt priorities 

� provides vectors for the processor to determine which interrupt routine to 

execute. 

The interrupt controller has priority assignment modes that can be reconfigured at any time 

during system operations. 

The interrupt levels are described in Table 1-6. Interrupt level assignments 0 through 15 are 

in order of decreasing priority. See Section 2 for information on using the Setup utility to 

change the interrupts.

Plug and Play 


The system comes with a Plug and Play BIOS in support of Plug and Play technology. Plug 

and Play simplifies setup procedures for installing Plug and Play expansion boards. With 

Plug and Play, adding a Plug and Play expansion board is done by turning off the system, 

installing the board, and turning on the system. There are no jumpers to set and no system 

resource conflicts to resolve. Plug and Play automatically configures the board. (Some Plug 

and Play devices may need to be jumpered if used in a system running the Windows NT ® 

operating system.) 

NLX Chassis 

The PowerMate Enterprise is designed to conform to the NLX standard. Electrical and 

mechanical interfaces and board dimensions are standardized: 

� signal and power connections to the system board are carried through the riser 

board 

� the system board is free of internal cabling 

� a pair of latches unseats the system board. 

These features make the system extremely easy to access, upgrade, and repair. 

ISA Bus 

The system board uses the ISA bus for transferring data between the processor and some 

I/O peripherals and expansion boards. The ISA bus supports 16-bit data transfers and 

typically operates at 8 MHz. ISA expansion slot connector pin assignments are provided in 

Appendix A. 

PCI Local Bus 

The 32-bit PCI bus is the primary I/O bus for the system. The PCI bus is a highly integrated 

I/O interface that offers the highest performance local bus available for the Pentium 

processor. The bus supports burst modes that send large chunks of data across the bus, 

allowing fast displays of high-resolution images. 

The PCI bus operates at half the Pentium processor’s bus speed. The PCI bus supports 

memory transfer rates of up to 105 MB per second for reads and up to 120 MB per second 

for writes, depending on processor configuration. 

The PCI bus eliminates the data bottleneck found in traditional systems, maintains maximum 

performance at high clock speeds, and provides a clear upgrade path to future technologies. 

PCI expansion slot connector pin assignments are provided in Appendix A.


PCI/IDE Ports 

The system board provides two high-performance PCI/IDE ports: a primary channel and a 

secondary channel (though the connectors are actually located on the riser board). Each 

port supports up to two devices for a total of four IDE devices. The primary PCI/IDE port 

has an enhanced IDE interface that supports PIO Mode 4 devices with 16 MB per second 

32-bit wide data transfers on the high-performance PCI local bus. Each channel supports 

Ultra DMA/33. 

The installed hard disk drive is connected to the primary PCI/IDE connector with a threeconnector 

cable. If a CD-ROM reader is included in the system, it is connected to the 

secondary PCI/IDE port with a three-connector cable. A second device can be added to the 

primary PCI/IDE channel. 

Parallel Interface 

The system has a 25-pin bidirectional parallel port on the system board. Port specifications 

conform to the IBM-PC standards. The port supports Enhanced Capabilities Port (ECP) 

and Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. 

The protocols allow high-speed bi-directional transfer over a parallel port and increase 

parallel port functionality by supporting more devices. 

The BIOS has automatic ISA printer port sensing that works with most devices. If the 

BIOS detects an ISA printer port mapped to the same address, the built-in printer port is 

disabled. (Verify in the BIOS Setup that printer ports mapped to the same address are 

enabled or disabled appropriately.) The BIOS also sets the first parallel interface port it 

finds as LPT1 and the second port it finds as LPT2. The interrupt is set at IRQ7 via the 

BIOS Setup utility. Software-selectable base addresses are 3BCh, 378h, and 278h. 

Sets of I/O addresses and interrupts for the parallel port are given in Table 1-8. This is a list 

of all possible configurations; the parallel port uses only one set. 

Table 1-8 Parallel Port Addresses and Interrupts

378 IRQ05 LPT1 


3BC IRQ05 LPT3 



3BC IRQ07 LPT3

NOTE: Any interrupts used for the built-in 

parallel port are not available for ISA parallel 

ports. 


Parallel interface signals are output through the system board’s 25-pin, D-subconnector. 

The connector is located at the rear of the system unit. Pin locations for the parallel 

interface connector are given in Appendix A. 

Serial Interface 

The system has two 16C550 UART compatible serial ports (COM1 and COM2) integrated 

on the I/O controller. The serial ports support the standard RS-232C interface. The buffered 

high-speed serial ports support transfer rates up to 115.2 KB. These ports allow the 

installation of high-speed serial devices for faster data transfer rates. 

Sets of I/O addresses and interrupt levels for the two channels are given in Table 1-9 and 

Table 1-10. (Note that COM2 is disabled by default.) The interrupt levels are selectable via 

the BIOS Setup utility and include IRQ3, IRQ4, IRQ10, and IRQ11. Software-selectable 

base addresses are 3F8h, 2F8h, 3E8h, and 2E8h. If serial ports are reconfigured to share an 

interrupt, verify that the software and hardware added by users can share interrupts without 

problems. 

NOTE: Any interrupts used for the built-in 

serial ports are not available for ISA parallel 

ports. 

If serial ports share an interrupt, verify that 

hardware and software added to the system can 

share these interrupts without problems.

The Universal Serial Bus (USB) port allows new Plug and Play serial devices to be added 

without having to open the system. The devices may be plugged into a USB port. The USB 

determines system resources for each peripheral and assigns them without user intervention. 

Up to 127 devices can be daisy chained to a single computer. Boot support for a USB 

keyboard is present so the system can be booted with a USB keyboard instead of a standard 

keyboard. 

Infrared Interface 

The I/O controller incorporates an infrared interface that provides two-way wireless 

communication through the IrDA window (port) on the front of the system. The interface 

uses infrared as the transmission medium instead of a traditional serial cable.


The IrDA port permits the transfer of files to or from portable devices such as laptops and 

personal digital assistant (PDA) products using the pre-installed LapLink ® applications 

software or other software supporting IrDA data transfer. The port supports data transfers 

at 115.2 Kbps from a distance of 1 meter (3 feet 3 inches). 

The IrDA port uses the system’s COM2 serial port to transfer data. The port shares 

registers and function logic with COM2. Note that COM2 is disabled by default, so it must 

be enabled before the IrDA port can be used. Enable COM2 from the Advanced menu of 

the BIOS Setup utility, under the Serial Port B submenu, and set Serial Port B Mode to 

IrDA. 

Video Interface 

The system board features the S3 Trio 64 ViRGE/GX 3D accelerator chip with 2 MB of 

video SGRAM soldered on the system board. 

The video and graphics controller accelerates color space conversion and video upscaling to 

deliver exceptional graphics and high quality MPEG and video playback and true 

multimedia functionality. MPEG is a compression/decompression standard developed by a 

professional video group called the Motion Picture Experts Group. MPEG produces fullscreen, 

30-frames-per-second, broadcast-quality digital video. 

The graphics accelerator chip provides: 

� outstanding TV-quality video playback

mode. 

Press the reset button (see Figure 2-10) to manually restart the system when it does not 

respond to keyboard commands. 

CD-ROM READER 

A twenty-four speed CD-ROM reader may come pre-installed in the system. The reader is 

set as a master device, and is connected to the secondary PCI/IDE port on the riser board. 

Specifications for the CD-ROM readers are given in Section 1, and jumper settings are 

given in Appendix B. 

The CD-ROM reader drive assignment varies according to the number and type of other 

devices installed in the system. 

Use the CD-ROM reader to load and start programs from a CD. If the system has audio 

capabilities, the CD-ROM reader can also be used to play audio CDs. The CD-ROM reader 

can also be configured as a bootable device if it is set first in boot order. 

NOTE: To use the CD-ROM reader as a 

bootable device, it must be set as the first 

bootable device in BIOS Setup. If it does not 

need to be a bootable device, set it as the last 

bootable device.


The CD-ROM reader has the following controls and indicators (see Figure 2-11): 

� jack for connecting headphones with a stereo mini-jack plug 

� volume control for adjusting the headphone volume 

� CD busy lamp that lights when the reader is retrieving data, music, or 

graphics/audio from a CD

Windows 95 operating system, the CD-ROM player starts as soon as the CD is inserted into 

the drive and the tray is closed. 

NOTE: If the Auto Insert Notification is 

enabled, the system does not automatically enter 

Power Management. For information on enabling 

and disabling Auto Insert Notification, see 

“Setting Auto Insert Notification” later in this 

section.


THE BIOS SETUP UTILITY 

This section describes the BIOS Setup utility program that allows system configuration 

information to be viewed and changed. 

NOTE: The system ships from the factory with 

the correct system parameters for the 

configuration. Unless setting the time and date, 

setting security features, customizing the system, 

or adding optional hardware, Setup does not 

need to be run. 

Most system configuration information is stored in nonvolatile memory. Nonvolatile 

memory in the system is a complementary metal-oxide semiconductor (CMOS) chip backed 

by a coin-type battery on the system board. (Some BIOS information is also stored in 

Extended System Configuration Data (ESCD), a separate segment of the ROM chip.) The 

battery supplies continuous power to the CMOS memory and maintains configuration 

information when system power is off. 

Using the BIOS Setup Utility 

The Setup utility is used to view and set system parameters. Use the Setup utility to: 

� set the time and date 

� update or check system parameters when adding or removing expansion options 

� change or set power management features 

� change or set boot options 

� change or set power management parameters 

� correct a hardware discrepancy when the Power-On-Self-Test (POST) displays an 

error message and a prompt appears to run Setup 

� check the installation of optional memory by comparing the amount of memory 

installed with the amount of memory displayed by Setup 

� configure system connections for peripherals such as the diskette drive, hard 

drives, devices connected to the printer and serial ports; configure onboard audio, 

video 

� customize the system with security features such as passwords, diskette drive 

restriction, virus check reminder, and system backup reminder 

� set system parameters if the CMOS battery needs replacing.

How to Start Setup 

To start the BIOS Setup utility, follow these steps. 

1. Turn on or reboot the system. 

2. Press F2 as soon as the NEC screen appears. 


For about five seconds after the system is booted, F2 can be used to bring up the 

Setup utility. 

3. If F2 is pressed, the Setup Main menu appears. It looks similar to the menu shown 

in Figure 2-12.

LANDESK CLIENT MANAGER 

The LANDesk ® Client Manager (LDCM) software program is provided with the computer. 

LDCM uses the Desktop Management Interface (DMI) standard to manage components 

(network interface cards, memory, software applications) within a client (local) or remote 

(workstation) PC system. It provides features for managing the resources of a local PC and 

can be used by system administrators to manage groups of computer systems.

With Client Manager, perform the following tasks: 


� review system inventory of workstation hardware and software components 

� view DMI-compliant component information 

� set security features to change password (on a local machine) or enable/disable 

the serial ports, printer, or diskette drive (from the local machine or by a system 

administrator from a local machine) 

� back up and restore system configuration files on a local machine or by a system 

administrator from a remote machine 

� back up system and application software using Cheyenne Backup 

� troubleshoot 

� receive notice of system events (for example, if the system is running low on 

memory, the user is notified of the potential problem) 

� detect changes to CPU, memory, and hard disk characteristics and alert the user 

to these changes (Configuration Change Notification) 

� transfer files to and from client workstations 

� remotely reboot client workstations. 

There are two main components of Client Manager: PC Health Indicator and Inventory. 

PC Health Indicator 

PC health indicator consists of three parts: 

� Managing workstations 

� PC Health meter 

� PC Health description. 

Managing Workstations 

Client Manager sets up a connection to all the workstations running on the network to 

allow the administrator to monitor the functions of each workstation. 

The monitoring is in real time. If an unhealthy workstation is fixed, refresh the screen to 

view the new correct PC health. The monitor can also be set to report only unhealthy 

workstations.


PC Health Meter 

The PC Health meter is a traffic signal that provides a visual indicator of workstation health. 

A red light indicates that a critical system event has occurred. This type of problem must be 

fixed immediately. 

A yellow light or noncritical system event requires that the situation be monitored. It may 

be a problem that could get worse and become a critical event. 

A green light indicates everything is working fine with the system. 

PC Health Description 

The description of PC health is determined by monitoring various system components for 

threshold levels. Some of the components that are monitored include: 

� drive space 

� prediction of hard drive failure (Smart Hard Drive failure prediction) 

� free virtual memory 

� temperatures 

� power supplies 

� chassis opened 

� GDI used 

� non-critical boot failure 

� boot virus detection. 

Once a threshold level has been passed on a workstation, request notification of the problem 

to have it written into a log file. 

Inventory 

Client Manager Inventory views the hardware and software components of the workstation. 

The inventory consists of the following categories: 

� workstation summary 

� basic hardware 

� drives 

� memory 

� audio 

� keyboard/mouse 

� video

� system resources 

� I/O ports 

� operating system 

� network 

� applications 

� system files 

� user information. 


In addition, from Client Manager Inventory, the current system configuration can be 

viewed, user information edited, and file snapshots created or restored. 

DMI 

As a part of the LANDesk Client Manager, the Desktop Management Interface (DMI) is 

the standard interface used to manage system components on the computer. Examples of 

system components are network interface cards and software applications. System 

components provide a Management Information Format (MIF) file to be DMI-compliant. 

The information file describes component attributes that can be managed. 

Client Manager can be used to “get” attribute information on system components. It can 

also be used to “set” attribute values in real time. 

Monitoring Capabilities 

The PowerMate Enterprise minitower computer has a chip mounted on the system board 

that supports many new and advanced real-time monitoring capabilities used by DMI. This 

chip provides the following features: 

� an integrated temperature sensor with configurable interrupt generation based on 

upper and lower temperature limits 

� a power supply monitor with configurable interrupt generation based on upper 

and lower voltage limits 

� chassis intrusion detection with interrupt generation capabilities. 

To take advantage of these features, DMI has expanded its interface in the following areas: 

� Interrupts may be enabled or disabled. 

� High and low limits can be set and are displayed for temperature and power 

supply voltages. 

Current readings are displayed for temperature, power supply voltages, and chassis state.


Interrupts can be detected when “out of range” conditions occur. User prompts are 

displayed to alert the user to a potentially harmful condition. 

Cheyenne Backup 

On systems that use the Windows 95 operating system, Cheyenne Backup is a data 

management and backup program that operates in conjunction with LANDesk Client 

Manager’s Smart Hard Drive Auto-Backup Utility. If hard drive performance degrades due 

to bad sectors or other internal problems, the Smart Hard Drive utility automatically 

invokes the Cheyenne Backup program and backs up the entire file system to tape, a Zip 

drive, or other removable storage media, such as a diskette drive. The program can also 

back files up to a network mapped drive. 

Cheyenne Backup can also do regularly-scheduled backups and scan files for viruses during 

a backup operation. 

NEC Security 

On systems that use the Windows 95 operating system, NEC Security features allow a local 

user to change NEC security passwords, and enable a local user or system administrator to 

control local machine devices, including printer ports, serial ports (except COM2 when set 

to IrDA mode), and diskette drives. 

NEC SELECT INSTALL CD 

The system comes with an NEC Select Install CD disc containing all the system software 

files. Should a problem occur that causes data loss or corruption, use the CD to restore 

these system files to their original factory-installed state on the computer. 

The Select Install CD can also be used to build a different configuration, or to just change 

part of the existing configuration. This utility provides the flexibility to meet a variety of 

hardware and software demands. 

The Select Install CD reinstalls all or part of the computer’s software in two phases: 

� operating system (OS) restore 

� selective application restore. 

Use phase one, the OS restore program, to completely reinstall Windows 95 or Windows 

NT from the CD. If a full restore is needed after a catastrophic system failure, start with this 

phase. Then perform phase two. 

Use phase two, the Selective Application Restore program, to restore selected applications 

from the CD at any time. This phase takes place while the OS is running. 

The following subsections explain how to use the NEC Select Install CD.

Operating System Restore Program 


OS Restore is the first phase of a full system restore. When the system boots from the NEC 

Select Install CD, it automatically loads the DOS-based Restore program. 

NOTE: To perform an OS Restore on 

non-SCSI configured systems, boot the system 

from the Select Install CD. 

NOTE: To perform an OS Restore on SCSI 

configured systems, first boot the system from 

the supplied SCSI bootable diskette, then 

proceed with the NEC Select Install procedure. 

Follow these steps to restore the original, factory-installed operating system using OS 

Restore. 

1. With system power on 

� for non-SCSI systems, insert the Select Install CD disc into the CD-ROM 

reader 

� for SCSI systems, insert the SCSI bootable disc into the diskette drive. 

2. Press Ctrl-Alt-Del to reboot the computer. 

� for non-SCSI systems, the system boots from the CD installed in the 

CD-ROM reader. The following Operating System Restore Welcome screen 

appears (see Figure 2-13). 

� For SCSI systems, after the system reboots from the diskette, remove the 

diskette, insert the Select Install CD disc into the CD-ROM reader, and reboot 

the system. The following Operating System Restore Welcome screen appears 

(see Figure 2-13).

GENERAL RULES FOR INSTALLING OPTIONS 

Follow these general rules when installing system options. 

� To prevent tipping, always place the system unit back in its stand after completing 

a system upgrade. 

� Turn off system power and unplug the power cable. 

� Turn off and disconnect all peripherals. 

� Before unplugging the power cable or handling boards or chips, touch the system 

unit frame to discharge static. 

� Do not disassemble parts other than those specified in the procedure. 

� All screws are Phillips-head, unless otherwise specified. 

� Label connectors before removing them. Note where the connector goes and in 

what position it was installed. 

PRECAUTIONS 

Take care when working inside the system unit and when handling computer components. 

Avoid electric shock or personal injury by observing the following warning and caution. 

WARNING: Before removing the system unit 

cover, turn off the power and unplug the system 

power cable. Power is removed only when the 

power cable is unplugged. 

CAUTION: Electrostatic discharge can damage 

computer components. Discharge static 

electricity by touching a metal object before 

removing the system unit cover.

Option Installation 3-3 

Static electricity and improper installation procedures can damage computer components. 

Protect computer components by following these safety instructions. 

� Avoid carpets in cool, dry areas. Leave an option, such as a board or chip, in its 

anti-static packaging until ready to install it. 

� Dissipate static electricity before handling any system components (boards, chips) 

by touching a grounded metal object, such as the system's unpainted metal chassis. 

If possible, use anti-static devices, such as wrist straps and floor mats. 

� Always hold a chip or board by its edges to avoid touching the components. 

� Take care when connecting or disconnecting cables. A damaged cable can cause a 

short in the electrical circuit. Misaligned connector pins can cause damage to 

system components at power-on. 

When installing a cable, route the cable so it is not pinched by other components 

and is out of the path of the system unit cover. Prevent damage to the connectors 

by aligning connector pins before you connect the cable. 

� When disconnecting a cable, always pull on the cable connector or strain-relief 

loop, not on the cable.

EXPANSION BOARDS 


The computer supports industry-standard architecture (ISA) 8- and 16-bit expansion 

boards, Plug and Play or non-Plug and Play (legacy). It also supports 32-bit PCI Plug and 

Play expansion boards. 

With Plug and Play expansion boards you can install a board in an expansion board slot 

without changing the hardware settings. There are no system resource conflicts to resolve. 

Plug and Play automatically configures the board for your system. 

Expansion Slot Locations 

The system has five expansion slots: three PCI slots, one shared PCI/ISA slot, and one ISA 

slot for half-length ISA boards (see Figure 3-8). The PCI slots support PCI expansion 

boards. The ISA expansion slots support industry-standard 8-bit or 16-bit expansion 

boards. The shared PCI/ISA slot does not support PCI Bus Mastering boards. 

PCI expansion boards run at half the system processor’s bus speed. The PCI bus handles 

32 bits of data at a time, being wider as well as faster than the standard ISA bus. PCI boards 

can send and receive data much faster, which boosts system performance. 

Figure 3-8 Locating Expansion Slots

� the standard hard drive and up to three additional IDE devices such as IDE hard 

disk drives, IDE CD-ROM reader, and IDE Zip drive. 

� the standard SCSI drive (SCSI configured systems only) and up to two additional 

SCSI devices). More SCSI devices can be installed using optional SCSI cables. 

Device Slots 

The system accommodates up to six storage devices (see Figure 3-16) in the following 

slots: 

� one 3 1/2-inch horizontal accessible device slot that contains the standard 

1.44-MB diskette drive 

� two 3 1/2-inch internal hard disk drive slots (thin-height). One contains the 

standard 3 1/2-inch IDE hard disk drive, or the SCSI hard drive for SCSI 

configured systems 

� three 5 1/4-inch accessible device slots (1.6-inch high, half-height). The slots 

might contain a CD-ROM reader, PCMCIA device, or Zip drive. 

Figure 3-16 Data Storage Slots


Devices such as a diskette drive or tape drive with a 5 1/4-inch adapter frame can be 

installed in the 5 1/4-inch slots. A 3 1/2-inch hard disk drive can also be installed in a 

5 1/4-inch slot if the drive is housed in a 5 1/4-inch adapter frame. 

Device Preparation 

Before installing an optional storage device in the system, follow any preinstallation 

instructions that come with the device. For example, the following devices typically need 

the preparation noted below: 

� Diskette drive ⎯ remove any termination on the optional diskette drive. See the 

documentation that comes with the drive. 

� IDE device ⎯ Check the jumper settings on the device before you install it. See 

the documentation that comes with the device for jumper setting information. 

Also see Table 3-2 for a listing of primary and secondary master/slave 

configuration combinations. 

⎯ In the BIOS Main Menu, an IDE device such as an IDE hard disk drive or 

IDE CD-ROM reader must be set correctly as the first (master) or second 

(slave) device on the IDE channel. 

⎯ In systems with an IDE hard disk drive, the drive is typically set as the master 

device on the primary IDE channel. A CD-ROM reader is typically set as the 

master device on the secondary IDE channel. 

� SCSI device (SCSI configured systems) ⎯ check the jumper settings on the 

device before installing it. 

⎯ Each SCSI device must have a SCSI ID number set for the device. See 

“SCSISelect Utility” in Section 2 of this manual for information on setting ID 

numbers. Also see Appendix B, “Jumper Settings,” and the device’s 

documentation for information on setting SCSI IDs. 

⎯ The last SCSI device on an internal or external SCSI cable must be 

terminated. See “SCSISelect Utility” in Section 2 of this manual and the 

device’s documentation for information on setting terminations.

Device Cables 

The cables used for the installation of optional storage devices include: 

� diskette drive signal cable 

� IDE signal cables 

� SCSI signal cable (SCSI configured systems only) 

� system power cables. 


The installed diskette drive cable supports the standard diskette drive and an optional 

diskette drive. The installed IDE cables support two devices each. The installed SCSI drive 

cable (SCSI configurations only) supports three devices. The diskette and IDE signal cables 

connect to the riser board connectors shown in Figure 3-17. The SCSI cable connects to the 

internal 68-pin connector on the SCSI adapter board. 

Figure 3-17 Riser Board Cable Connectors


Diskette Drive Signal Cable 

A three-connector diskette drive signal cable comes attached to the riser board and to the 

standard 1.44-MB diskette drive. An optional 1.2-MB diskette drive can be added to the 

system, using the unused middle connector on the signal cable. 

Figure 3-18 shows the three-connector diskette drive signal cable. The colored edge of the 

cable goes to pin 1 on the riser board cable connector and pin 1 (the notched end) on the 

drive connector. 

Figure 3-18 Three-Connector Diskette Drive Signal Cable

IDE Signal Cables 


The system comes with two 3-connector IDE interface cables, one attached to the primary 

IDE connector on the riser board and one connected to the secondary IDE connector on the 

riser board. In systems with an IDE hard disk drive, the drive is connected to the primary 

IDE connector on the riser board. If the system has a CD-ROM reader, it is connected to 

the secondary IDE connector on the riser board. Each IDE connector on the riser board 

supports two IDE devices. 

Figure 3-19 shows a typical three-connector IDE cable. If the IDE cable is not keyed with a

MAINTENANCE 

This subsection contains general information for cleaning and checking the system, 

keyboard, and monitor. 

The system, keyboard, and monitor require cleaning and checking at least once a year, and 

more often if operating in a dusty environment. No other scheduled maintenance or 

lubrication is required. 

System Cleaning 

WARNING: Unplug all power cords before 

performing any maintenance. Voltage is present 

inside the system and monitor even after the 

power is off. All voltage is removed only when 

the power cord is unplugged. 

Use the following procedure for cleaning the system. 

1. Power off the system and unplug all power cables. 

2. Wipe the outside of the system, keyboard, mouse, and monitor with a soft, clean 

cloth. Remove stains with a mild detergent. Do not use solvents or strong, 

abrasive cleaners on any part of the system. 

3. Clean the monitor screen with a commercial monitor screen cleaning kit. As an 

alternative, use a glass cleaner, then wipe with a clean lint-free cloth. 

4. Local distributors and dealers may sell diskette drive head cleaning kits. These kits 

contain special diskettes and cleaning solution. Do not use the abrasive head 

cleaning kits (kits without cleaning solution). 

Insert the diskette immediately after powering on the system, before the disk 

boot-up. Allow the diskette drive heads to clean for about 30 seconds.

Keyboard Cleaning 

As necessary, inspect and clean the inside of the keyboard as follows. 


1. Remove the eight screws holding the keyboard enclosure together (see 

Figure 4-1). 

NOTE: The keyboard and cable together are 

considered a whole-unit, field-replaceable 

assembly. Therefore, disassembly of the 

keyboard is necessary only when cleaning the 

inside. 

Figure 4-1 Removing the Keyboard Enclosure 

2. Separate the two halves of the enclosure. 

3. Clean the enclosure and keys with a damp cloth. A small, soft-bristle brush may be 

used to clean between the keys. Do not wet or dampen the keyboard’s printed 

circuit board (PCB). If the PCB accidentally gets wet, thoroughly dry it before 

reattaching the keyboard to the system unit.


Mouse Cleaning 

The mouse has a self-cleaning mechanism that prevents a buildup of dust or lint around the 

mouse ball and tracking mechanism under normal conditions. Periodically, however, the 

mouse ball must be cleaned. Use the following procedure to clean the mouse. 

1. Unplug the mouse from the system. 

2. Turn the mouse upside down and locate the mouse ball cover (see Figure 4-2). 

3. Turn the ball cover counterclockwise and remove the cover. 

Figure 4-2 Removing the Mouse Ball Cover 

4. Turn the mouse over and remove the ball. 

5. Clean the mouse as follows: 

� Clean the mouse ball with tap water and a mild detergent, then dry it with a 

lint-free cloth. 

� Remove any dust and lint from the mouse socket. 

6. Replace the mouse ball in its socket. 

7. Replace the ball cover and turn it clockwise until it locks in place.

Jumper Settings 

The following sections provide jumper settings for the PowerMate Enterprise minitower 

computers. Settings are included for the following components: 

� system board 

� IDE and SCSI hard disk drives 

� CD-ROM reader 

� fax/modem board 

� tape backup drive 

� Iomega Zip drive. 

SYSTEM BOARD JUMPER SETTINGS 

System board jumper settings are changed under the following circumstances: 

� upgrading the processor 

� resetting your password 

� performing BIOS recovery. 

NOTE: Jumpers are set correctly at the factory for 

the system configuration. 

If the system requires a jumper change, change 

only the setting for that condition. Otherwise, 

keep the settings at their factory settings. 

WARNING: The system power must be off 

before the cover is removed.

B-2 Jumper Settings 

Figure B-1 shows the jumper locations on the system board. Explanations for changing each 

system board jumper setting follow the figure. 

Processor Jumpers

Password Clear Jumper 

Use the following steps to clear the password. 

Jumper Settings B-3 

1. With the system powered off and unplugged, jumper J6J1 for Configure Mode 

(see Figure B-2). 

Figure B-2 Password Clear Jumper 

2. Restart the system. The Setup utility launches automatically. Setup displays the 

Maintenance Menu, which is available only in Configure Mode. 

3. From the Maintenance Menu, perform a Clear Password according to the menu 

choices and system prompts. 

4. Power off and unplug the system. Jumper J6J1 for normal operation (see 

Figure B-2). 

5. Restart the system and run Setup to establish a new password (see “The Security 

Menu” in Section 2 for complete instructions).


BIOS Recovery Jumpers 

If an interruption occurs during a BIOS upgrade that prevents continuation of the process, 

it is possible that the BIOS may be left in an unstable state. If this happens, BIOS Recovery 

must be performed. This entire procedure is performed in conjunction with a BIOS 

Recovery diskette. This procedure is seldom required; if it is, see the instructions that are 

provided with the diskette. 

You can obtain the BIOS Recovery program by downloading it to a diskette from the 

NECCSD Bulletin Board System (BBS) or the NECCSD File Transfer Protocol (ftp) site. 

See “NECCSD Bulletin Board System” for information on accessing the BBS. See 

“Internet” in Section 4 for information on accessing the NECCSD ftp site. 

In order to perform BIOS Recovery, pins 1, 2, and 3 on J6J1 must be unjumpered.

FEDERAL COMMUNICATIONS COMMISSION 

RADIO FREQUENCY INTERFERENCE STATEMENT 

WARNING: Changes or modifications to this unit not expressly approved by the party 

responsible for compliance could void the user’s authority to operate the equipment. 

NOTE: This equipment has been tested and found to comply with the limits for a Class B 

digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide 

reasonable protection against harmful interference in a residential installation. This 

equipment generates, uses and can radiate radio frequency energy and, if not installed and 

used in accordance with the instructions, may cause harmful interference to radio 

communications. 

However, there is no guarantee that interference will not occur in a particular installation. If 

this equipment does cause harmful interference to radio or television reception, which can 

be determined by turning the equipment off and on, the user is encouraged to try to correct 

the interference by one or more of the following measures. 

� Reorient or relocate the receiving antenna. 

� Increase the separation between the equipment and receiver. 

� Connect the equipment to an outlet on a circuit different from the one to which the 

receiver is connected. 

Use a shielded and properly grounded I/O cable to ensure compliance of this unit to the 

specified limits of the rules. 

FCC Modem Connection Requirements 

The Federal Communications Commission (FCC) has established Rules that permit this 

device to be directly connected to the telephone network. Standardized jacks are used for 

these connections. This equipment should not be used on party lines or coin lines. 

If the modem is malfunctioning, it may also be harming the telephone network. Disconnect 

the modem until the source of the problem is determined and repairs are made. If this is not 

done, the telephone company may temporarily disconnect service. 

The telephone company may make changes in its technical operations and procedures. If 

such changes affect the compatibility or use of the modem, the telephone company is 

required to give adequate notice of the changes. You will be advised of your right to file a 

complaint with the FCC.

If the telephone company requires information on what equipment is connected to their 

lines, inform them of: 

� The telephone number to which this unit is connected. 

� The ringer equivalence number (see the modem label). 

� The USOC jack required. 

� The FCC Registration number (see the modem label). 

The ringer equivalence (REN) is used to determine how many devices can be connected to 

your telephone line. In most areas, the sum of the RENs of all devices on any one line 

should not exceed five (5). If too many devices are attached, they may not ring properly. 

Modem Service Requirements 

If the modem malfunctions, all repairs should be performed by NEC Computer Systems 

Division or an NECCSD Authorized Service Center. It is the responsibility of users 

requiring service to report the need for service to NEC Computer Systems Division or to an 

NECCSD Authorized Service Center. Service can be obtained at: 

NEC Computer Systems Division, Inc. 

1414 Massachusetts Avenue 

Boxborough, Massachusetts 01719-9984 

Phone: 1-800-233-6321

(For Canadian Use Only) 

This equipment is a Class B digital apparatus which complies with the Radio Interference 

Regulations, C.R.C., c.1374. 

Cet appareil numérique de la classe B est conforme àu Règlement sur le brouillage 

radioélectrique, C.R.C., ch.1374. 

Canadian Department of Communications Modem Connection Requirements 

NOTE: The Canadian Department of Communications label identifies certified equipment. 

This certification means that the equipment meets certain telecommunications network 

protective, operational and safety requirements. The Department does not guarantee the 

equipment will operate to the user’s satisfaction. 

Before installing this equipment, users should ensure that it is permissible to be connected 

to the facilities of the local telecommunications company. The equipment must also be 

installed using an acceptable method of connection. In some cases, the company’s inside 

wiring associated with a single line individual service may be extended by means of a 

certified connector assembly (telephone extension cord). The customer should be aware that 

compliance with the above conditions may not prevent degradation of service in some 

situations. 

Repairs to certified equipment should be made by an authorized Canadian maintenance 

facility designated by the supplier. Any repairs or alterations made by the user to this 

equipment, or equipment malfunctions, may give the telecommunications company cause to 

request the user to disconnect the equipment. 

Users should ensure for their own protection that the electrical ground connections of the 

power utility, telephone lines and internal metallic water pipe system, if present, are 

connected together. This precaution may be particularly important in rural areas. 

WARNING: Users should not attempt to make such connections themselves, but should 

contact the appropriate inspection authority or electrician. 

The Load Number (LN) assigned to each terminal device denotes the percentage of the 

total load to be connected to a telephone loop which is used by the device, to prevent 

overloading. The termination on a loop may consist of any combination of devices subject 

only to the requirement that the total of the Load Numbers of all the devices does not 

exceed 100.

BATTERY REPLACEMENT 

A lithium battery in your computer maintains system configuration information. In the event 

that the battery fails to maintain system configuration information, NECCSD recommends 

that you replace the battery (see Section 4, “Maintenance and Troubleshooting,” for battery 

removal procedures). 

WARNING: There is a danger of explosion if the battery is incorrectly replaced. Replace 

only with the same or equivalent type recommended by the manufacturer. Discard used 

batteries according to the manufacturer’s instructions. 

ATTENTION: Il y a danger d’explosion s’il y a replacement incorrect de la batterie. 

Remplacer uniquement avec une batterie du même type ou d’un type recommandé par le 

constructeur. Mettre au rébut les batteries usagées conformément aux instructions du 

fabricant. 

BATTERY DISPOSAL 

Do not place used batteries in your regular trash. 

The nickel-cadmium or nickel metal-hydride batteries must be collected, recycled, or 

disposed of in an environmentally approved manner. 

The incineration, landfilling, or mixing of batteries with the municipal solid waste stream is 

prohibited by law in most areas. 

Return batteries to a federal or state approved battery recycler. This may be where 

you purchased the battery or a local seller of automotive batteries. In MINNESOTA, call 

1-800-225-PRBA if further disposal information is required. 

Contact your local waste management officials for other information regarding the 

environmentally sound collection, recycling, and disposal of the batteries.
