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.

22 1-8 Technical Information 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.

27 Technical Information 1-13 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.

29 Technical Information 1-15 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.

30 1-16 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 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 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

31 Technical Information 1-17 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 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. 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.

33 Technical Information 1-19 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. 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.

70 2-12 Setup and Operation 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.

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.

91 Setup and Operation 2-33 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.

92 2-34 Setup and Operation 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

93 Setup and Operation 2-35 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.

94 2-36 Setup and Operation 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.

95 Setup and Operation 2-37 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.

208 B-4 Jumper Settings 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.
