27 1-10 Technical Information Processor and Secondary Cache The system uses an Intel Pentium II processor with an internal clock speed of 233 MHz, 266 MHz or 300 MHz. Each processor uses 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 on the processor. The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386, Intel486, Pentium, and Pentium Pro processors. The Pentium II processor is mounted on a CPU card with an attaching heatsink that installs as unit (CPU subsystem) in Slot 1 on the system board. 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.

28 Technical Information 1-11 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 memory map is shown in Table 1-3.

System Memory The system comes with between 32 MB and 384 MB of SDRAM installed in dual in-line memory module DIMM sockets on the system board. The memory configuration consists of three sockets. The DIMM memory sockets accept 168-pin, 64-bit (non-parity) 16-, 32-, 64-, and 128-MB DIMMs (64-MB and 128-MB as available). Table 1-5 lists the supported DIMMs. Table 1-5 Memory Configurations DIMM Size Type Configuration Technology 16 MB CAS Latency 2 SDRAM 2-Mbit x 64-bit 16 Mbit 32 MB CAS Latency 2 SDRAM 4-Mbit x 64-bit 16 Mbit 64 MB CAS Latency 2 SDRAM 8-Mbit x 64-bit 64 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.

32 Technical Information 1-15 Hardware Monitor The National Semiconductor Heceta LM79 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.

33 1-16 Technical Information 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 BIOS Setup utility to change the interrupts. Table 1-6 Interrupt Level Assignments* Interrupt Priority Interrupt Device IRQ00 System Timer IRQ01 Keyboard IRQ02 Programmable Interrupt Controller IRQ03 COM2* IRQ04 COM1* IRQ05 LPT2 (plug and play option)/audio integrated on system board/user available IRQ06 Diskette Drive Controller IRQ07 Parallel Port 1 IRQ08 Real-time clock IRQ09 User available IRQ10 User available (SCSI board for SCSI configurations) IRQ11 Available (used by network board if present) IRQ12 Mouse IRQ13 Reserved, Math Coprocessor IRQ14 Primary IDE IRQ15 Secondary IDE * In Plug and Play systems, these interrupts are typical but may vary by configuration.

34 Technical Information 1-17 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 latch 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.

35 1-18 Technical Information 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 on the riser board with a two-connector cable. If a CD-ROM reader is included in the system, it is connected to the three-connector cable supplied on the secondary PCI/IDE port. A second device can be added to either PCI/IDE channel (if the device is being added to the primary PCI/IDE channel, the two-connector cable must be replaced with a three-connector cable). Parallel Interface The system has a 25-pin bi-directional 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 Interrupt Starting I/O Address Interrupt Level Port 378 IRQ05 LPT1 278 IRQ05 LPT2 3BC IRQ05 LPT3 378 IRQ07 LPT1 278 IRQ07 LPT2 3BC IRQ07 LPT3

36 Technical Information 1-19 NOTE: 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 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 (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.

Serial interface specifications include: Baud rate up to KB per second 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 s 9-pin, D-subconnectors. The connectors are located at the rear of the system unit. Pin locations for the serial interface connector are shown in Appendix A. USB Interface The Universal Serial Bus (USB) port allows new Plug and Play serial devices to be added without having to open the system. One USB device may be plugged into the USB port for direct system connection. With a hub and the proper cabling, up to 127 USB devices can be addressed by the system. The USB determines system resources for each peripheral and assigns them without user intervention. Boot support for a USB keyboard is present so the system can be booted with a USB keyboard instead of a standard keyboard.

38 Technical Information 1-21 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 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. Graphics Capabilities The system supports accelerated graphics port (AGP) and PCI graphics boards. A PCI graphics board installs in one of the computer s PCI expansion slots. An AGP graphics board installs in the system board s AGP connector. The following graphics boards are available from NECCSD: ATI XPERT@Work AGP 2X graphics board This board contains 4 MB of Synchronous Graphics random-access memory (SDRAM), upgradeable to 8 MB using a daughter card. Cirrus Logic DM-5465 AGP graphics board This board contains 2 MB of video memory.

Accelerated Graphics Port The system board contains a 132-pin accelerated graphics port (AGP) connector that supports graphics-intensive, 3D applications. The AGP operates independently of the PCI bus and supports 133-MHz data transfer rates, allowing 500 MB of data to be transmitted per second. The AGP is Plug and Play compatible and supports the ATI XPERT@Work AGP and Cirrus Logic DM-5465 graphics board options available from NECCSD. With the graphics board installed in the AGP connector, attach the display monitor to the board s VGA-compatible connector on the rear panel. Graphics Controller The graphics controller is specifically designed for graphics-intensive operations, including 3D and 2D effects, texture mapping, text and color pixel amplification, and video acceleration. The controller minimizes bus traffic by off-loading the tasks normally performed by the processor, providing 64-bit, high resolution performance for demanding True Color displays and other sophisticated graphics functions. Motion Video Controller The motion video controller integrates a Windows graphical user interface (GUI) engine and motion video playback hardware. Support includes: MPEG-1 or MPEG-2 Video for Windows Active Movie (Windows 95 only).

The system might be connected via a 3COM network board: thin Ethernet cable and onboard transceiver using a BNC connector (3COM 3C509B) twisted-pair cable and onboard transceiver using an RJ-45 connector (3COM 3C905-TX and 3COM 3C509B) thicknet cable with an external transceiver using an AUI (DB15) connector (3COM 3C509B). Specifications for network boards are given in Table 1-33 and Table SCSI ADAPTER BOARD Systems that ship with an Ultra Wide SCSI hard disk drive come with an Adaptec 2940 SCSI adapter board installed in a PCI expansion slot. The SCSI adapter board brings the highest performance SCSI I/O technology to the PCI local bus, transferring data up to 133 MB/second. The SCSI adapter board is compatible with all major operating systems, including SCSI-1, SCSI-2 and SCSI-3 peripherals, and industry-standard application software. The BIOS-resident SCSISelect configuration utility eliminates the need to handle jumpers or terminators while adding peripherals. All configuration and terminator settings are controlled via the keyboard (see SCSISelect Utility in Section 2). The SCSI adapter board includes the following features: PCI to UltraSCSI host adapter with SCSISelect, using the PCI local-bus to support up to fifteen SCSI devices Bus master DMA interface protocol 32-bit bus width up to 133 MB/second host bus burst data rate Fast and Wide 40 MB/second SCSI synchronous data rate 3.3 MB/second SCSI asynchronous data rate SCSI-1, SCSI-2, SCSI-3, and Wide UltraSCSI device protocol advanced SCSI features including multi-threaded I/O (up to 255 tasks simultaneously), scatter/gather, tagged command queuing, disconnect/reconnect, and synchronous and asynchronous data transfer extended translation scheme supports up to eight GB per disk

48 Technical Information 1-31 drivers may be single-ended, active, or programmable via the SCSISelect configuration utility 50-pin 8-bit internal SCSI connector for connecting optional internal SCSI devices 68-pin 16-bit internal SCSI connector for connecting to the internal SCSI hard drive (SCSI configured systems only) 68-pin 16-bit external SCSI connector for connecting optional external SCSI devices. Up to 15 SCSI devices (seven standard internal and eight 16-bit wide internal or external, or 15 wide internal and external SCSI devices) can be connected to the adapter board.

If the program on the CD-ROM is based on the 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 The BIOS Setup utility is used to configure the main components of the computer. NOTE: The system ships from the factory with the correct system parameters for the configuration. Unless you add optional hardware, you do not need to run Setup to operate the system. However, you might wish to run the Setup utility to set features that customize the system, such as security features. System configuration information is stored in nonvolatile memory. A nonvolatile memory device retains its data when system power is turned off. Nonvolatile memory in the system is stored in a complementary metal-oxide semiconductor (CMOS) chip backed up by a battery on the system board. The battery supplies continuous power to CMOS memory and maintains configuration information when system power is off (see Replacing the Battery in Chapter 8). NOTE: NECCSD recommends that you print out or write down the current Setup parameters and store the information in a safe place. This will enable you to restore the system to the current parameters if you ever need to replace the battery.

81 2-12 Setup and Operation 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 you add or remove expansion options change or set power management features correct a hardware discrepancy when the Power-On Self-Test (POST) displays an error message and prompts you to run Setup check the installation of optional memory by comparing the amount of memory installed with the amount of memory displayed by Setup change certain system operating parameters, such as boot device sequence and keyboard parameters configure system connections for peripherals such as the diskette drive, hard disks, and devices connected to the printer port and serial ports customize the system with security features such as passwords, diskette drive restriction, virus check reminder, and system backup reminder set system parameters in the event that you need to replace the complementary metal oxide semiconductor (CMOS) battery. How to Start Setup To start the Setup utility, follow these steps: 1. Turn on or reboot the system. 2. To start the memory test before the system boots up, press F2 after POST. There is about five seconds in which to press F2 before the system boot continues.

99 2-30 Setup and Operation LANDESK CLIENT MANAGER LANDesk Client Manager (LDCM) is a software program 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 you can 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 remote machine) back up and restore system configuration files back up system and application software using the NEC Auto Backup utility troubleshoot receive notice of system events (for example, if the system is running low on memory, you are notified of the potential problem) detect changes to CPU, memory, and hard disk characteristics and alert you 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.

100 Setup and Operation 2-31 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 so that if an unhealthy workstation is fixed, you can refresh the screen to view the new correct PC health. You can also set the monitor 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. You are required to fix 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 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, you can request notification of the problem and have it written into a log file.

101 2-32 Setup and Operation 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 or restore file snapshots. 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.

102 Setup and Operation 2-33 Monitoring Capabilities Your PowerMate Enterprise computer has a chip mounted on the system board that supports many new and advanced real-time monitoring capabilities used by DMI. This chip (NEC MagicEye Technology) 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 (see Using the Chassis Intrusion Notification Feature ). 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. The Chassis Intrusion Notification Feature LANDesk Client Manager allows you to monitor the system against chassis intrusion. Whenever the chassis is opened, LANDesk Client Manager logs the intrusion and reports the incident in a screen message the next time the system is booted. The message appears in a LANDesk Client Manager Notification window. This window appears every time the system is rebooted until the report is cleared. Close the notification window to remove the message from the screen. Clear the message to prevent it from appearing again the next time the system is rebooted. To clear the message, follow these steps. 1. Access LANDesk Client Manager. If the LANDesk Client Manager Notification window is still open, click Yes, and then click the Client Manager button. From the Windows desktop, click Start on the taskbar, point to Programs, point to LANDesk Client Manager, and click LANDesk Client Manager 3.0. LANDesk Client Manager opens.

103 2-34 Setup and Operation 2. Open the Tools menu and click PC Health. The PC Health window appears. The Chassis Opened field displays the Yes setting. 3. Click Clear next to the Chassis Opened field. 4. Exit from LANDesk Client Manager. NEC Auto Backup On systems that use the Windows 95 operating system, NEC Auto Backup is a data management and backup program that operates in conjunction with LANDesk Client Manager s DMI and the Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) Hard Drive instrumentation. If the S.M.A.R.T. drive identifies a potential problem, the NEC Auto Backup utility automatically invokes the Cheyenne Backup program and backs up the entire file system to a user-selected backup device, such as a tape drive, Zip drive, or network drive. NEC Auto Backup can also do regularly-scheduled backups and scan files for viruses during a backup operation. NOTE: For the NEC Auto Backup utility to work, Cheyenne Backup must be preconfigured. See the NEC Auto Backup utility Read Me file for information about Cheyenne Backup. NEC SELECT INSTALL CD The following procedures for using the NEC Select Install CD that ships with the system replace the procedures in the printed user s guide. Please read the following sections in their entirety before using the NEC Select Install CD to restore any software on the system. Introducing Select Install Options The system comes with an NEC Select Install compact disc (CD). (Systems with a SCSI hard disk drive also come with a Boot Diskette.) The CD contains all the system software files that came with the computer. Should a problem occur that causes data loss or corruption, you can restore these system files to their original factory-installed state on the computer.

104 Setup and Operation 2-35 The Select Install CD reinstalls all or part of the computer s software. Depending on the operating system in use and the way the Select Install CD is used, you can do one or more of the following: operating system (OS) restore with disk rebuild (deletes all data on the disk) operating system (OS) restore only, for systems running the Windows 95 operating system (preserves data on the disk) selective application restore. The OS Restore programs and the Selective Application Restore program use easy-tounderstand dialog boxes and screen messages so you can smoothly proceed through the restore process. Choosing a Restore Program It s important to choose the appropriate restore program. In some uses, the program can delete all the data, as well as the operating system and/or applications on the hard disk. Read the list below to verify that the program you choose fits the conditions under which you are performing the restore. Repartition and/or reformat the hard disk and restore the operating system ( Auto or Custom ). If there is a catastrophic system failure, use the OS restore to repartition and reformat the hard disk and restore the operating system. Using the program is the first phase of a full system restore. After restoring the OS, continue with a Selective Application Restore. See the section called Rebuilding the Hard Disk and Restoring the Operation System, and under it, either Auto Rebuild and Restore or Custom Rebuild and Restore. Restore only the operating system ( Fix OS ). If the hard disk does not need to be rebuilt, use the OS Restore to reinstall only the operating system (for systems running the Windows 95 operating system). A selective application restore does not need to be performed after only the operating system is reinstalled. See the section called Restoring the Operating System. Restore some or all of the applications that came with the system. The Selective Application Restore takes place after the Windows OS has booted. It lets you choose the application software to reinstall. Use this program to restore selected applications from the CD after rebuilding the hard disk, or at any time to reinstall a software package that came with the computer.

105 2-36 Setup and Operation See the section called Restoring Applications. CAUTION: If possible, back up data before performing an OS restore. Rebuilding the Hard Disk and Restoring the Operating System The OS Restore allows you to repartition and/or reformat the hard disk and then reinstall Windows 95 or Windows NT from the CD. You can rebuild the disk and reinstall the operating system in one of two ways: Auto, to perform a standard rebuild and restore Custom, to rebuild and restore with greater control over restore functions. NOTE: The Auto and Custom programs repartition and/or reformat the hard disk drive before reinstalling the operating system. To only reinstall the operating system in a Windows 95 system while leaving applications and data files intact, see Restoring the Operating System. The following sections explain how to use the NEC Select Install CD to rebuild and restore the system. See Auto Rebuild and Restore to repartition and reformat the hard disk with the OS restore. See Custom Rebuild and Restore for more options when you repartition and/or reformat the hard disk with the OS restore. After performing an OS restore that also repartitions and/or reformats the hard disk, run a Selective Application Restore to reinstall any application that came with the system. See Restoring Applications for directions on running this program. Auto Rebuild and Restore To perform an auto OS Restore that also repartitions and reformats the hard disk, boot the system from the Select Install CD (in systems with a SCSI hard disk drive, boot the system from the Boot Diskette and immediately insert the Select Install CD). When the system boots, it automatically loads the MS-DOS -based Operating System Restore program. CAUTION: If possible, back up data before performing an OS restore.

106 Setup and Operation 2-37 Follow these steps to rebuild the hard disk and restore the original, factory-installed operating system using OS Restore: 1.
