Technical Information

SYSTEM OVERVIEW

NEC PowerMate Enterprise NetPC computers are designed to enable centraladministration of computer resources in network environments. A highly manageableplatform, the NetPC features network boot capabilities, controlled upgrade paths for systemenhancements, and a “sealed case” that prevents end-user access for changing the systemhardware or software configuration.

NOTE: The PowerMate NetPC system isdesigned to be repaired by qualified, NECCSD-trained technicians at the depot level of service.

PowerMate NetPC systems are available in two basic models with the following features:

� Windows® 95 operating system, 166-MHz Intel® Pentium® MMX processor,16 MB (minimum) of Synchronous Dynamic Random-Access Memory(SDRAM), and a 2.0-GB IDE hard disk drive

� Windows NT® 4.0 operating system, a 200-MHz Intel Pentium MMX processsor,32 MB of SDRAM, and a 3.2-GB hard disk drive.

The MMX processor technology boosts audio, video, and 3D graphics performance.

Both PowerMate NetPC models come with an RJ-45 network connector and a video chipwith 2 MB of Synchronous Graphics Random-Access Memory (SGRAM).

Both models also contain audio/video components for multimedia presentations and supportoptional memory expansion modules. For further hardware enhancements, both modelscontain a PCI expansion slot for adding an optional, half-length, plug and play-compatiblePCI board.

The system features two USB ports, two serial ports, and one parallel port. Ultra DMA,remote wakeup (“Wake on LAN”), 3D graphics, and power management are supported.

Build choices include hard disk drive and Pentium MMX processor upgrades. Systemmemory is provided in 16-MB, 32-MB, and (as available) 64-MB and 128-MB DIMMsticks, in memory configurations ranging from 16 MB to 256 MB.

Figures 1-1 and 1-2 show the front and back features of the PowerMate NetPC system.

1-2 Technical Information

Processor and Secondary Cache

The system uses an Intel Pentium processor with an internal clock speed of 166 MHz,or 200 MHz. These processors use Intel MMX technology.

The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed tooptimize multitasking operating systems. The 64-bit registers and data paths support 64-bitaddresses and data types.


The MMX processor has 32 KB of built-in cache memory (16 KB instruction and 16 KBdata). To use the Pentium processor’s power, the system features an optimized 64-bitmemory interface and 256 KB of secondary write-back cache located on 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 into asocket-7 zero insertion force (ZIF) socket. Systems with the 166-MHz processor can beupgraded to 200-MHz. The socket provides an easy upgrade path.

System BIOS

The system BIOS is from Intel, based on Phoenix Technologies Limited (PTL) BIOS ‘95.This ISA- and PCI-compatible BIOS is contained in a flash memory device on the systemboard. The BIOS provides the Power-On Self-Test (POST), the system Setup program, aPCI and IDE auto-configuration utility, and BIOS recovery code.

The system BIOS is always shadowed. Shadowing allows any BIOS routine to be executedfrom 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 areprogrammable EPROM containing both the system and video BIOS. Using the FlashROM 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 maintenancecosts are reduced

� there is less chance of inadvertently damaging the system board than whenphysically 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, andinteract with the display, diskette drives, hard disk drives, communication devices, andperipherals. The system BIOS also contains the Setup utility. The POST copies the ROMBIOS into RAM (shadowing) for maximum performance.

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Updateutility, without having to physically remove the ROM (see Section 2 for further informationon the BIOS Update utility). The Flash ROM supports the reprogramming of the systemBIOS and the video BIOS.

The system memory map is shown in Table 1-3.

System Memory

The system comes with between 16 MB and 256 MB of SDRAM installed in dual in-linememory module DIMM sockets on the system board.

The memory configuration consists of two sockets. The DIMM memory sockets accept168-pin, 64-bit (non-parity) 8-, 16-, 32-, 64-, and 128-MB DIMMs. Table 1-5 lists thesupported DIMMs.

Table 1-5 Memory Configurations

DIMM Size Type Configuration Technology

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






Memory upgrades are easy with DIMMs. Advantages of using DIMMs are listed below:

� 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.

� The 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 instrumentationcapabilities (NEC MagicEye™ Technology) for reduced cost of PC ownership when thesystem 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 ClientManager v.3.0

When ranges for temperature, fan speed, 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 toexecute.

The interrupt controller has priority assignment modes that can be reconfigured at any timeduring system operations.

The interrupt levels are described in Table 1-6. Interrupt level assignments 0 through 15 arein order of decreasing priority. See Section 2 for information on using the Setup utility tochange the interrupts.

The following audio resources vary depending on which operating system or environmentthey run under (default based on shipping configurations):

� Base I/O address: 220-22f

� FM Synthesis address: 388-38B

� MPU-401 MIDI address: 330-331

The following information indicates the possible resources that a sound component canhave after third party devices have been added to the system:

� Joystick address: 201

� Base address: 220 to 250

� FM Synthesis address: 388

� MPU-401 MIDI address: 330

� Audio DMA: 0, 1, 3

� Audio IRQ: 5, 7, 9, 10

� MPU-401 MIDI IRQ: 5, 7, 9, 10


Plug and Play

The system comes with a Plug and Play BIOS in support of Plug and Play technology. Plugand Play simplifies setup procedures for installing Plug and Play expansion boards. WithPlug 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 systemresource 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.)

Chassis

The NetPC chassis is divided into two sheet-metal halves. The system has one 3.5-inchdrive slot for a hard drive and one add-in card slot, which accepts a half-length PCI card.The dimensions of the chassis are included in Table 1-16.

Power connections to the system board are carried through the riser card, which alsocontains the half-length PCI card slot.

PCI Local Bus

The 32-bit PCI bus is the primary I/O bus for the system. The PCI bus is a highly-integratedI/O interface that offers the highest performance local bus available for the Pentiumprocessor. 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 supportsmemory transfer rates of up to 105 MB per second for reads and up to 120 MB per secondfor writes, depending on processor configuration.

The high-bandwidth PCI bus eliminates the data bottleneck found in traditional systems,maintains maximum performance at high clock speeds, and provides a clear upgrade path tofuture technologies.

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


PCI/IDE Ports

The system board supports one high-performance PCI/IDE port (the primary channel for amaster/slave configuration), though the port is actually located on the riser card. The portsupports one or two devices in a master/slave setting configurable in BIOS Setup. Theprimary PCI/IDE port has an enhanced IDE interface that supports PIO Mode 4 deviceswith 16 MB per second 32-bit wide data transfers on the high-performance PCI local bus.The channel supports Ultra DMA/33. The installed hard disk drive is connected to theprimary PCI/IDE port with a two-connector cable. A second Ultra DMA/33 device can belogically added to the primary PCI/IDE channel, but in such a case, neither device shouldrun in Ultra DMA/33 mode because the length of the three-connector cable required for thisconfiguration would cause signal degradation.

NOTE: Physically, the chassis only has room forone hard disk drive.

Parallel Interface

The system has a 25-pin bi-directional parallel port on the system board. Port specificationsconform 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 increaseparallel port functionality by supporting more devices.

The BIOS has automatic ISA printer port sensing that works with most devices. If theBIOS detects an ISA printer port mapped to the same address, the built-in printer port isdisabled. (Verify in the BIOS Setup that printer ports mapped to the same address areenabled or disabled appropriately.) The BIOS also sets the first parallel interface port itfinds as LPT1 and the second port it finds as LPT2. The interrupt is set at IRQ7 via theSetup 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 listof all possible configurations; the parallel port uses only one set.

228 IRQ07 LPT3


NOTE: Any interrupts used for the built-inparallel port are not available for ISA parallelports.

Parallel interface signals are output through the system board 25-pin, D-subconnector. Theconnector is located at the rear of the system unit. Pin locations for the parallel interfaceconnector are given in Appendix A.

Serial Interface

The system has two 16C550 UART compatible serial ports (COM1 and COM2) integratedon the I/O controller. The serial ports support the standard RS-232C interface. The bufferedhigh-speed serial ports support transfer rates up to 115.2 KB. These ports allow theinstallation 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 andTable 1-10. (Note that COM2 is disabled by default.) The interrupt levels are selectable viathe Setup utility and include IRQ3 and IRQ4. Software selectable base addresses are 3F8h,2F8h, 3E8h, and 2E8h. If serial ports are reconfigured to share an interrupt, verify that thesoftware and hardware added by users can share interrupts without problems.


NOTE: Any interrupts used for the built-inserial ports are not available for ISA parallelports.

If serial ports share an interrupt, verify thathardware and software added to the system canshare these interrupts without problems.

� Word length 5, 6, 7, or 8 bits

� Stop bit 1, 1.5, or 2 bits

� Start bit 1 bit

� Parity bit 1 bit (odd parity or even parity).


Serial interface signals are output through the system board 9-pin, D-subconnectors. Theconnectors are located at the rear of the system unit. Pin locations for the serial interfaceconnector are shown in Appendix A.

USB Interface

The Universal Serial Bus (USB) ports allow new Plug and Play serial devices to be addedwithout having to open the system. The devices may be plugged into a USB port. The USBdetermines system resources for each peripheral and assigns them without user intervention.With a hub and the proper cabling, up to 127 devices can be daisy chained to a singlecomputer. Boot support for a USB keyboard is present so the system can be booted with aUSB keyboard instead of a standard keyboard.

Video Interface

The system board features the S3 Trio 64 ViRGE/GX 3D accelerator chip with 2 MB ofvideo SGRAM soldered on the system board.

The video and graphics controller accelerates color space conversion and video upscaling todeliver exceptional graphics and high quality MPEG and video playback and truemultimedia functionality. MPEG is a compression/decompression standard developed by aprofessional video group called the Motion Picture Experts Group. MPEG produces full-screen, 30-frames-per-second, broadcast-quality digital video.

The graphics accelerator chip provides:

� Outstanding TV-quality video playback

� Accelerated multimedia and application performance

� Brilliant true color graphics

� Razor-sharp photo-realistic images

� Ultra-fast game action

� Texture mapping performance for 3D games, 3D Web browsing, 3Dpresentations, and other 3D applications.


The default video mode is 800 by 600 pixels with 256 colors. The system also supports theresolutions, colors, and refresh rates listed in Table 1-11.

Integrated Audio

To support the increasing number of multimedia applications, a Yamaha OPL3-SA3 chip is

integrated on the system board. The chip provides 16-bit stereo, Sound Blaster Pro-compatible audio. System boards with audio provide a line out jack and microphone jack.

The sound system provides all the digital and analog mixing functions required for playingand recording audio on personal computers. Features include stereo analog-to-digital anddigital-to-analog converters, analog mixing, anti-aliasing and reconstruction filters, line andmicrophone level inputs, digital audio compression, and full digital control of all mixer andvolume control functions.

The sound system is standard and features the following:

� Yamaha OPL3-SA3 chip integrated on system board

� digital audio and analog mixing functions, including stereo analog-to-digital anddigital-to-analog converters, analog mixing, anti-aliasing and reconstructionfilters, line and microphone level inputs, digital audio compression, and full digitalcontrol of mixer and volume control functions

� Adlib, Sound Blaster Pro 2.0, Windows Sound System, and MPU-401compatibility.


The Yamaha OPL3-SA3 includes a full Plug and Play interface. Each logical device isconfigured into the host environment using the Plug and Play configuration methodologies.The audio subsystem requires two DMA channels and one interrupt.

DISKETTE DRIVE SUPPORT

A diskette drive is not included in the system. However, the riser card contains a diskettedrive connector and controller. A diskette drive with its own power source can beconnected by a ribbon cable to the diskette drive connector on the riser card. You mustenable the diskette drive controller in BIOS Setup to use a diskette drive in the NetPCsystem (see “Setup Utility” in Section 2).

HARD DISK DRIVE

All systems ship with one internal 3 1/2-inch hard disk drive (1-inch high, thin-height)installed in the internal drive slot in the top half of the chassis. Drives are available in2.0-GB and 3.2-GB Western Digital models.

A two-connector hard disk drive IDE cable connects to the hard disk and the primaryconnector on the riser card. The riser card has one IDE/PCI interface connector (primaryonly) for connecting IDE storage devices such as hard disk drives. Logically, the connectorsupports up to two IDE devices. Physically, there is room for one hard disk in the chassis.

An optional second hard disk drive can be added to the primary channel if the cable isreplaced with a three-connector IDE cable. If an additional hard disk drive is added to theprimary IDE channel, configure both devices as non-Ultra DMA.

Use the “Storage Device Installation” procedures in Section 3 when replacing the hard disk.Connector locations are given in Appendix A. Jumper settings are given in Appendix B.Hard disk drive specifications are given in Table 1-17 and Table 1-18.

POWER SUPPLY

The power supply is mounted inside the top chassis. It supplies power to the system board,option board, hard disk, keyboard, and mouse. A fan inside the chassis provides systemventilation. The power supply provides 51 watts (rated). Connector locations are given inAppendix A.

The power supply connector differs from the standard NLX and ATX power supplyconnectors. Pin 18 of the PowerMate NetPC power supply is used for thermal fan speedcontrol and not for -5V.

WARNING: Do not use a standard NLX orATX power supply to operate the NetPC system,as this will cause the fan circuit to fail.


The power supply supports remote power on/off. This means that the system board andriser card can turn off the system power through software control. Pin 14 of the powersupply connector lets the system board recognize a power supply that supports this “soft-off” feature.

To enable soft-off control in software, power management (PM) must be enabled in theoperating system. When the system BIOS receives the correct PM command from theoperating system, the BIOS turns off power to the computer. For example, in the Windows95 Start menu, the user selects Shutdown to turn off the power.

Depending on how “Restore On AC/Power Loss” is configured in the Setup utility (see“Boot Menu” in Section 2), if power to the computer is interrupted by a power outage or adisconnected power cord, when power resumes, the computer returns to the state it was inbefore the power interruption. The default CMOS setting for a power loss is “Last State.”

RISER CARD

The riser card serves as an interface between the system board and the network andbetween the system board and any installed PCI expansion board. The riser card contains anRJ-45-compatible LAN connector for connecting the system to an Ethernet network. Thecard also contains a PCI expansion slot for installing a half-length PCI expansion board. Theriser card connects to the system board through a 170-pin edge connector and alsocable-connects to the power supply to provide DC power to the NetPC system components.The riser card contains one primary IDE connector for the system’s hard disk and alsocontains a diskette drive connector. For more information on riser card features, seeTable 1-21. Connector pin assignments for the riser card are provided in Appendix B.

MOUSE

A Microsoft IntelliMouse is standard equipment for the system. This PS/2-compatiblemouse has two buttons and a cursor control button. The mouse has a self-cleaningmechanism that prevents a buildup of dust or lint around the mouse ball and trackingmechanism. The six-pin mouse cable connector plugs into the rear of the system. Mousespecifications are given in Table 1-14.

KEYBOARD

The PS/2-compatible keyboard is standard equipment for the system. The keyboardprovides a numeric keypad, separate cursor control keys, 12 function keys, and is capable ofup 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 rear of thesystem. Keyboard specifications are given in Table 1-15.

SETUP UTILITY

The Setup utility program is used to configure the main components of the computer.

NOTE: The system ships from the factory withthe correct system parameters for theconfiguration. Unless you add optional hardware,you do not need to run Setup to operate thesystem. However, you might wish to run theSetup utility to set features that customize thesystem, such as security features.

System configuration information is stored in nonvolatile memory. A nonvolatile memorydevice retains its data when system power is turned off. Nonvolatile memory in the systemis stored in a complementary metal-oxide semiconductor (CMOS) chip backed up by abattery on the system board. The battery supplies continuous power to CMOS memory andmaintains configuration information when system power is off.

NOTE: NECCSD recommends that you printout or write down the current Setup parametersand store the information in a safe place. Thisallows you to restore the system to the currentparameters if you ever need to have the batteryreplaced.


When to Use Setup

The Setup utility lets you view and set system parameters. Use the Setup utility program to:

� set the time and date.

� update or check system parameters when expansion options have been added orremoved.

� change or set power management features.

� correct a hardware discrepancy when the Power-On Self-Test (POST) displays anerror message and prompts you to run Setup.

� check the installation of optional memory by comparing the amount of memoryinstalled with the amount of memory displayed by Setup.

� change certain system operating parameters, such as boot device sequence andkeyboard parameters.

� configure system connections for peripherals, such as devices connected to theprinter port and serial ports.

� customize the system with security features such as passwords, virus checkreminder, and system backup reminder.

� set system parameters in the event that the CMOS battery has been replaced.

How to Start Setup

To start the Setup utility, follow these steps:

1. Turn on or reboot the system.

2. Press F2 after POST to start the Setup utility before the system boots up.

There is about five seconds in which to press F2 before the system boot continues.

NOTE: These parameter also appear inConfiguration mode as part of the BIOSrecovery procedure described in Appendix B. Donot change the floppy option settings unless youare recovering the system BIOS in Configurationmode

Primary IDE

The Primary IDE Master and Slave settings control the system’s hard disk drive.

The computer comes with the hard disk drive (drive C:) configured as the “Primary IDEMaster.” The system can support a maximum of two IDE drives (master and slave) on theprimary IDE channel. Menu choices include:

� Primary Master

� Primary Slave.

The default setting for existing installed Master devices is “Auto,” meaning that the systemautomatically detects the hard disk type and sets the remaining parameters. The defaultsetting for existing installed Slave devices is “None.”

If a hard disk drive that does not feature auto IDE type detection has been installed (or theIDE hard disk was formatted on another system with parameters different than thosereported by the drive), enter a parameter for each of the following fields.

CAUTION: When set to Auto Detected, theBIOS detects what the drive is capable of, notthe translation mechanism that was used toformat the drive.

If a drive is run in a mode other than the mode inwhich it was partitioned and formatted,unpredictable results may occur, including dataloss.


� TypeUse this field to enter the hard disk drive type. The following options areavailable:

“Auto” automatically configures the device.

“User” prompts the user to fill in the remaining fields.

“None” indicates that no device is selected.

� CylindersEnter the number of cylinders.

� HeadsEnter the number of read/write heads.

� SectorsEnter the number of sectors per track.

� Maximum CapacityThis read-only field displays the capacity of the hard disk drive installed in thesystem.

� Multiple Sector TransfersEnter the number of sectors transferred per block. Choices include “Disabled” (nosectors chosen), “Standard” (one sector), 2, 4, 8, and 16 sectors.

� LBA Mode ControlWhen “Enabled” is selected, it causes logical block addressing to be used in placeof cylinders, heads, and sectors.

� Transfer ModeEnter the method for transferring the data between the hard disk drive and thesystem memory. The Setup menu only lists those options supported by the drive.Choices can include

8. Reboot the system and start the Setup program. Press F9 to reset the BIOSdefaults. Then, use the copy of the Setup selections you made at the beginning ofthis procedure to set the parameters.

LANDESK CLIENT MANAGER

LANDesk Client Manager (LDCM) is a software program available on the NEC SelectInstall CD. LDCM uses the Desktop Management Interface (DMI) standard to managecomponents (network interface cards, memory, software applications) within a Client(local) or remote (workstation) PC system. It provides features for managing the resourcesof a local PC and can be used by system administrators to manage groups of computersystems.

See “NEC Select Install CD” for instructions on installing LANDesk Client Manager on theNetPC hard disk.

With Client Manager you can perform the following tasks:

� review system inventory of workstation hardware and software components

� view DMI-compliant component information

� troubleshoot

� receive notice of system events (for example, if the system is running low onmemory, you are notified of the potential problem)


� detect changes to CPU, memory, and hard disk characteristics and alert you tothese changes

� 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:

� Workstation management

� PC Health meter

� PC Health description.

Workstation Management

Client Manager sets up a connection to all the workstations running on the network toallow the administrator to monitor the functions of each workstation.

The monitoring is in real time so that if an unhealthy workstation is fixed, you can refreshthe screen to view the new correct PC health. You can also set the monitor to report onlyunhealthy 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. You are required tofix the problem immediately.

� A yellow light or noncritical system event requires that you monitor the situation.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 forthreshold levels. Some of the components that are monitored include:

� drive space

� prediction of hard drive failure with automatic data backup (see “NEC AutoBackup Utility for further information)

� free virtual memory


� temperatures

� power supplies

� chassis opened

� non-critical boot failure

� boot virus detection.

Once a threshold level has been passed on a workstation, you can request notification of theproblem and 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.

You can also view the current system configuration, edit user information, and create orrestore file snapshots.


DMI

The Desktop Management Interface (DMI) is the industry-standard used to manage systemcomponents on the computer. The PowerMate NetPC uses this standard along withLANDesk Client Manager to ensure interoperability among different vendor’s computers.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 canalso be used to “set” attribute values in real time.

More information on DMI is available on the World Wide Web at http://www.dmtf.org .

Monitoring Capabilities

The PowerMate NetPC computer has a chip (NEC MagicEye™ technology) mounted onthe system board that supports many new and advanced real-time monitoring capabilitiesused by DMI. This chip provides the following features:

� an integrated temperature sensor with configurable interrupt generation based onupper and lower temperature limits

� a power supply monitor with configurable interrupt generation based on upperand 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 can be enabled or disabled.

� High and low limits can be set and are displayed for temperature and powersupply voltages.

� Current readings are displayed for temperature, power supply voltages, andchassis state.

� Interrupts can be detected when “out of range” conditions occur. User promptsare displayed to alert the user to a potentially harmful condition.


NEC AUTO BACKUP UTILITY

The NEC Auto Backup utility is a data management and backup program that operates inconjunction with LANDesk’s DMI and the Self-Monitoring Analysis and ReportingTechnology (S.M.A.R.T) Hard Drive instrumentation. If the S.M.A.R.T. drive identifies apotential problem, the NEC Auto Backup utility automatically invokes the CheyenneBackup program and backs up the entire file system to a user-selected backup device, suchas a Zip drive, network drive, or tape.

NEC Auto Backup can also do regularly-scheduled backups and scan files for virusesduring a backup operation.

NOTE: For the NEC Auto Backup utility towork, Cheyenne Backup must be preconfigured.See the NEC Auto Backup utility “Read Me” filefor information about Cheyenne Backup.

The NEC Auto Backup utility is available on the NEC Select Install CD. See “NEC SelectInstall CD” for instructions on installing the NEC Auto Backup utility on the NetPC harddisk.

NEC SELECT INSTALL CD

The system comes with an NEC Select Install compact disc (CD). This disc contains all thesystem software files. Use the NEC Select Install CD to download the operating system andapplication software from a hardware/software service platform, such as LANDeskConfiguration Manager (LCM). Should a problem occur that causes data loss or corruption,you can restore the system files using the NEC Select Install CD.

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

� operating system (OS) restore program

Power Supply Connectors

Table A-18 provides the pin assignments for the riser card power supply connector (J3J1).

The power supply connector differs from the standard NLX and ATX power supplyconnectors. Pin 18 of the PowerMate NetPC power supply is used for thermal fan speedcontrol and not for -5V.

WARNING: Do not use a standard NLX orATX power supply to operate the NetPC system,as this will cause the fan circuit to fail.

The power supply supports remote power on/off. This means that the system board andriser card can turn off the system power through software control. Pin 14 of the powersupply connector lets the system board recognize a power supply that supports this “soft-off” feature.

Appendix B

Jumper Settings

This appendix contains jumper settings for the PowerMate NetPC system board and risercard.

SETTING SYSTEM BOARD JUMPERS

System board jumpers enable you to configure the system for a particular systemrequirement.

Conditions that require changing jumper settings include the following situations:

� You are upgrading the processor. You need to check that jumpers are setcorrectly for processor upgrade (see “Changing Processor Jumper Settings”).

� You forgot your password and cannot boot the system. You need to set a jumperto “clear” the current password (see “Clearing a Password”).

� The BIOS has become corrupted and you must perform a BIOS Recovery. Thisentire procedure is performed in conjunction with a BIOS Recovery diskette. Thisprocedure is seldom required; if it is, see “Recovery Mode” in this section and theinstructions that are provided with the diskette.

You can obtain the BIOS Recovery program by downloading it to a diskette fromthe NECCSD Bulletin Board System (BBS) or the NECCSD File TransferProtocol (FTP) site. See “NECCSD Bulletin Board System” in Chapter 4 forinformation on how to download files onto a diskette. See “Internet” inChapter 4 to access the NECCSD FTP site.

Normal Mode

Normal mode is for normal computer booting and operation. To enable this mode, connectpins 1 and 2 on the configuration jumper (J6J1). The BIOS uses the current bus/processorfrequency ratio, configuration information, and passwords. (Access to the Setup utility canbe restricted using an Administrative or User password. See “Clearing Your Password” formore information.)

B-6 Jumper Settings

Configure Mode

Configure mode is for configuring special BIOS settings, including processor speed andspecial maintenance options. Use this mode to upgrade or recover the BIOS or clear apassword. To enable this mode, connect pins 2 and 3 on the configuration jumper (J6J1)shown in Figure B-1.

After setting the jumper for Configure mode, turn on the computer. The Setup utilityautomatically executes after the POST runs. No password is required. This mode overridesany passwords that are set. The Maintenance menu appears for setting parameters. Thismenu provides options for setting the processor speed and clearing passwords.

The Maintenance menu provides access to the Password Clear selection. Use the PasswordClear selection in the Maintenance menu if the password must be reset.

NOTE: The Maintenance menu only appearswhen the system board has been jumpered forConfigure mode. When the system is restarted inConfigure mode, the Setup utility launchesautomatically and comes up in the Maintenancemenu. The Main, Advanced, PowerManagement, Security, Boot, and Exit menus arealso available.

Configure mode uses the default BIOS settings for booting (not the current administrativeor user settings). The default settings include using the lowest bus/processor frequency ratiothat the processor supports. Administrative and user settings are preserved and used whenthe computer reboots.

NOTE: For the configuration changes to takeeffect after exiting the Setup utility, turn off thecomputer, set the configuration jumper toNormal Mode, and turn on the computer.

Recovery Mode

Recovery mode is for upgrading the BIOS or recovering BIOS data. To enable this mode,leave pins 1, 2, and 3 unconnected on the configuration jumper (J6J1).

After the computer turns on, the BIOS upgrades or recovers BIOS data from a recoverydiskette in a diskette drive (with its own power source) that connects to the diskette driveconnector on the riser card. If a diskette is not in the diskette drive, the system does notboot or turn on the display, but the computer beeps continuously (one long and three shortbeeps). If the recovery fails when a recovery diskette is inserted in the diskette drive, a beepcode indicates that the recovery failed.

Jumper Settings B-7

You can obtain the BIOS Recovery program by downloading it to a diskette from theNECCSD Bulletin Board System (BBS) or the NECCSD File Transfer Protocol (FTP) site.See “NECCSD Bulletin Board System” in Section 4 for information on how to downloadfiles onto a diskette. See “Internet” in Section 4 to access the NECCSD FTP site.

For additional information, see the instructions that are downloaded with the files onto thediskette.

NOTE: For the configuration changes to takeeffect after the BIOS Recovery procedurefinishes, turn off the computer, set theconfiguration jumper to Normal Mode, and turnon the computer.
