25 Technical Information 1-8 Processor The PowerMate series of computers use the following Pentium processors: PowerMate P2166M 166-MHz MMX processor with internal speed of 166 MHz and external speed of 66 MHz. PowerMate P2200M 200-MHz MMX processor with internal speed of 200 MHz and external speed of 66 MHz. Each processor has 32 KB of write-back primary cache and a math coprocessor. The 32 KB primary cache provides 16 KB for instructions and 16 KB for data. 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 complementary asynchronous pipelined 256-KB secondary cache. The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386, Intel486, and Pentium processors. To accommodate future technologies and work requirements, the Pentium processor comes in a 320-pin zero insertion force (ZIF) socket. The socket provides an upgrade path to the next generation processor. Secondary Cache The system board contains 256 KB of pipeline-burst, external to the processor. Cache allows data to be sent or received from cache with one wait state burst. Cache memory improves read performance by holding copies of code and data that are frequently requested from the system memory by the processor. Cache memory is not considered part of the expansion memory.

26 Technical Information 1-9 System and Video BIOS The system and video BIOS are stored in a DMI-compliant, 2 MB (256K x 8) flash memory device (Flash ROM). The system BIOS uses 64 KB and the video BIOS uses 32 KB. The system BIOS is capable of being shadowed and cached through the system s Setup utility (see Section 2 for Setup information). System BIOS is write protected and automatically enabled. In addition to the system and video BIOS, the flash device contains the Setup Utility program described in Section 2, Power-On Self-Tests, and Advanced Power Management routines. The BIOS programs execute the Power-On Self-Test, initialize processor controllers, and interact with the display, diskette drives, hard disks, communication devices, and peripherals. The Setup utility default 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 removing 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 provided in Table 1-4.

27 Technical Information 1-10 System Memory Non-multimedia systems come standard with 16 MB of memory: 640 KB of base memory and 15 MB of extended memory. Most other configurations come with a 2.0-GB hard disk and 16 MB of memory: 640 KB of base memory and 15 MB of extended memory. Multimedia configurations ship with a 3.0-GB hard disk drive and 32 MB of system memory. System memory can be expanded up to 384 MB using optional single in-line memory modules (SIMMs) installed in SIMM sockets on the system board. Six SIMM sockets are integrated on the system board. Non-multimedia systems ship with two 8-MB SIMMs (16 MB total) installed in two sockets. The 32-MB systems ship with two 16-MB SIMMs installed. The SIMM memory sockets accept 32-bit (non-parity) or 36-bit (parity) 4-, 8-, 16-, 32- or 64-MB 60 ns Extended Data Output (EDO) or Fast Page Mode (FPM) SIMMs. The SIMMs are 1 MB x 32 bit (4 MB), 2 MB x 32 bit (8 MB), 4 MB x 32 bit (16 MB), 8 MB x 32 bit (32 MB), and 16 MB x 32 bit (64 MB). When the standard SIMMs are removed, six 64-MB SIMMs (FPM only when available) may be installed for a total of 384 MB. CAUTION: SIMMs must match the tin metal plating used on the system board SIMM sockets. When adding SIMMs, use tin-plated SIMMs. SIMMs install directly in the six sockets on the system board. The six sockets are assigned as SIMM 1 through SIMM 6. Each pair of SIMM sockets are called banks. There are three SIMM banks (labeled bank 0, 1, and 2). Systems ship with the two standard SIMMs installed in SIMM sockets 1 and 2. SIMMs must be installed in pairs of the same memory type. Jumpers are not required to set memory size or type as the system BIOS automatically detects the SIMMs. See Section 3, Option Installation for the recommended SIMM memory upgrade paths. Integrated Graphics The system has an ATI GT-B PCI 64-bit 3-D multimedia graphics and video controller integrated on the system board. State of the art techniques are used for optimizing performance in computer graphic intensive applications and graphical user interfaces (GUI). Features include: DDC rev 2b compliance video acceleration and 3-D rendering full screen Native video playback 2 MB of synchronous graphics random-access memory (SGRAM).

28 Technical Information 1-11 Video Memory PowerMate P MMX systems come with 2 MB of on-board video SGRAM, upgradeable to 4 MB. The first megabyte of SGRAM is mounted on the system board. Two connectors on the system board accept a 1- or 3-MB video module, providing a total of 2 MB or 4 MB of SGRAM. NOTE: PowerMate P MMX systems have 1 MB of SGRAM on the system board and a 1 MB video module installed as standard equipment. To upgrade from the standard 2 MB to 4 MB, you must replace the standard 1 MB video module with a 3 MB video upgrade module.

31 Technical Information 1-14 ISA Bus The system board uses the ISA bus for transferring data between the processor and 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 s processor speed, and 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 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 to future technologies. The PCI bus contains two embedded PCI devices, the PCI local bus IDE interface and the PCI video/graphics controller. PCI expansion slot connector pin assignments are provided in Appendix A. PCI Auto Configuration The system comes with a PCI auto configuration utility that operates in conjunction with the system s Setup utility. The utilities automatically configure interrupts, DMA channels, I/O space, and other parameters to allow addition of PCI boards with minimal user intervention. (See Section 2 for Setup information.) PCI/IDE Ports The system board provides two high-performance PCI/IDE ports: a primary channel and a secondary channel. Each port supports up to two devices for a total of four IDE devices. The primary PCI/IDE port has an enhanced IDE interface which supports 11.1 MB per second 32-bit wide data transfers on the high-performance PCI local bus. The installed hard disk drive is connected to the primary PCI/IDE port. The installed CD-ROM reader (multimedia and zip drive systems only) is connected to the secondary PCI/IDE port.

32 Technical Information 1-15 Parallel Interface The system has a 25-pin parallel bidirectional enhanced 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 bidirectional transfer over a parallel port and increase parallel port functionality by supporting more devices. The BIOS has automatic ISA printer port sensing. If the BIOS detects an ISA printer port mapped to the same address, the built-in printer port is disabled. The BIOS also sets the first parallel interface port it finds as LPT1 and the second port it finds as LPT2. The interrupt is selected to either IRQ5 or IRQ7 via Setup. Software selectable base addresses are 3BCh, 378h, and 278h. I/O addresses and interrupts for the parallel port are given in Table 1-7. NOTE: Any interrupts used for the built-in parallel port are not available for ISA parallel ports. Table 1-7 Parallel Port Addressing and Interrupts Starting I/O Address Interrupt Level Port 378 IRQ05 LPT1 278 IRQ05 LPT1 or LPT2 3BC IRQ05 LPT1 or LPT2 378 IRQ07 LPT1 278 IRQ07 LPT1 or LPT2 3BC IRQ07 LPT1 or LPT2 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 and the IrDA interface (see Table 1-8). The buffered high-speed serial ports supports transfer rates up to 19.2 KB. These ports allow the installation of high-speed serial devices for faster data transfer rates.

33 Technical Information 1-16 I/O addresses and interrupt levels for the two channels are given Table 1-8. The interrupt level is selectable via Setup to either IRQ3 or IRQ4. Software selectable base addresses are 3F8h, 2F8h, 3E8h, and 2E8h. NOTE: Any interrupts used for the built-in serial ports are not available for ISA parallel ports. Table 1-8 Serial Port Addressing and Interrupts Starting I/O Address Interrupt Level Port 3F8h IRQ04 COM1 2F8h IRQ03 COM2* 3E8h IRQ04 COM3 2E8h IRQ03 COM4 * Used for IrDA data transfer Note that the COM2 port is factory set for IrDA data transfer and must be reset to Standard for serial port transfers. See Section 2 for information on resetting the port through the Setup Utility. Serial interface specifications include: Baud rate up to 19.2 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-subconnector. 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 you to add new plug and play serial devices without opening up the system. You simply plug the devices into the 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.

34 Technical Information 1-17 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 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 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. POWER SUPPLY The power supply is mounted inside the system unit. It supplies power to the system board, option boards, diskette drives, hard disks, keyboard, and mouse. A fan inside the power supply provides system ventilation. The power supply provides 200 watts. Connector locations are in Appendix A. DISKETTE DRIVE Up to two diskette drives are supported in the desktop and minitower systems. The installed 3 1/2-inch diskette drive is connected by a single ribbon cable with two drive connectors. The diskette drive cable plugs directly into the system board. Typically both diskette drives are terminated. Connector locations are given in Appendix A. HARD DISK DRIVE Up to four IDE hard drives are supported in the desktop and minitower systems. The system board has two IDE/PCI interface connectors (primary and secondary) for connecting various storage devices such as hard disk drives. Each connector supports up to two IDE devices. Desktop hard disk systems ship with one internal 3 1/2-inch hard disk drive (1-inch high, thin-height) installed behind the front panel. The drive cable plugs into the primary (fast) connector on the system board. Minitower hard disk systems ship with one internal 3 1/2-inch hard disk (1-inch high, thinheight) installed behind the front panel, at the bottom of the chassis. The three-connector drive cable plugs into the primary (fast) connector on the system board. An optional second hard drive can be connected to the cable and installed at the bottom of the minitower chassis (see Section 3). Adding a third hard drive requires an optional two-drive connector cable (NEC part number ). The optional cable plugs into the secondary connector on the system board. If adding a fourth hard drive (in a 5 1/4-inch accessible slot), it connects to the unused connector on the optional cable.

35 Technical Information 1-18 KEYBOARD The PS/2-style 104 key keyboard is standard equipment for the system. The keyboard provides a numeric keypad, separate cursor control keys, and 12 function keys, capable of up to 48 functions. Status lamps on the keyboard indicate: Num (Numeric) Lock, Caps (Capital) Lock, and Scroll Lock key status. The keyboard s six-pin connector plugs into the rear of the system. The keyboard connector pin assignments are given in Appendix A. MOUSE A PS/2-compatible mouse is standard equipment for the system. The mouse has a selfcleaning mechanism that prevents a buildup of dust or lint around the mouse ball and tracking mechanism. The mouse s six-pin connector plugs into the rear of the system. The mouse connector pin assignments are given in Appendix A. MULTIMEDIA COMPONENTS Systems configured for multimedia come with audio integrated on the system board, a CD-ROM reader, a speaker set, and a microphone. The following briefly describes each. Information on setting up and operating the speakers, microphone, and CD-ROM reader is in Section 2. Integrated Audio Multimedia systems come with audio components integrated on a Creative Labs Vibra 16C single-chip VLSI mounted on the system board. Non-multimedia systems do not have the audio components on the system board. The Vicra 16C provides all the digital audio and analog mixing functions required for recording and playing audio on the computer. The Vibra 16C integrates FM synthesis and provides Sound Blaster and Roland MPU-401 UART mode compatibility. The integrated components also provide MPCII, Ad Lib, and Multimedia PC Level 2 compliance for PC sound applications. The components work with the pre-installed audio software (Voyetra ) and accomodate a variety of I/O addresses, DMA channels, and interrupts (see Table 1-5 for interrupt assignments and Table 1-6 for the system I/O address map). The audio subsystem requires up to two DMA channels to support full duplex operation and one interrupt.

36 Technical Information 1-19 CD-ROM Reader A sixteen-speed IDE CD-ROM reader is pre-installed as drive F on multimedia configurations. The reader can be used to load programs from a CD or it can be used to play audio CDs. The reader operates at different speeds depending on whether the CD contains music or data. This allows you to get your data faster and to see smoother animation and video. The reader is fully compatible with Kodak Multisession Photo CDs and standard CDs. The reader is set as the master device on the secondary IDE/PCI connector port. NOTE: You can boot the system from the CD-ROM with a bootable CD. To enable the system to boot from the CD-ROM, see Boot Options in Section 2. Speakers PowerMate P2166M/P2200M Series multimedia models come with 20 watt high-quality stereo speakers, an AC adapter, and connecting wires. The speaker set features a volume control, power on/off button, power lamp, bass control, treble control, and a mini-stereo headphone jack. Volume is controlled from the speaker or from the preinstalled sound system software. The speaker set connects to the speaker line out jack on the back of the system. Microphone The microphone that comes with the multimedia systems allows recording of voice and sound into computer data files. The microphone connects to the MIC jack located on the back of the system. The microphone works in conjunction with the audio software shipped with the system.

37 Technical Information 1-20 PLUG AND PLAY The system comes with a Plug and Play BIOS which supports Plug and Play technology. Plug and Play eliminates complicated 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. POWER MANAGEMENT The BIOS supports Advanced Power Management (APM) features. The energy-saving Stand-By mode can be initiated by a keyboard hot key sequence set by the user, a time-out period set by the user, or by a suspend/resume button tied to the front panel sleep connector. While in Stand-By mode, the system board reduces power consumptiom utilizing the Pentium processor s System Management Mode (SMM) capabilities.the monitor goes blank and the IDE hard drives spin down. NOTE: The ability to respond to external interrupts, such as network messages, is fully maintained, allowing the system to service requests while unattended. Any keyboard or mouse activity brings the system out of energy-saving Stand-By mode (the monitor and IDE drives are turned back on). The system can be manually put into a Suspend energy-saving mode by pressing the suspend button. A blinking power lamp indicates that the system is in the power-saving mode. As soon as activity is detected, the system resumes where it left off. APM is enabled in BIOS by default. APM parameters and features, such as the amount of inactive time, are configurable through the Setup utility. See Section 2 for information on setting power mangement parameters through Setup. The system must be configured with an APM driver before the power saving features take affect. Windows 95 enables APM automatically when it detects the presence of the APM BIOS.

38 Technical Information 1-21 LANDESK CLIENT MANAGER LANDesk Client Manager is provided with your PowerMate system. For installation procedures, see LANDesk Client Manager Setup and Using LANDesk Client Manager in Section 2. With Client Manager you can review system inventory. view DMI-compliant component information. back up and restore system configuration files. troubleshoot. receive notice of system events. 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 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.

39 Technical Information 1-22 PC Health Meter The PC Health meter is a traffic signal that provides a visual indicator of workstation health. A red light means 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 means 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 the following: drive space prediction of hard drive failure free virtual memory temperatures power supplies chassis opened GDI 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.

40 Technical Information 1-23 Inventory Client Manager Inventory views the hardware and software components of your 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.

41 Technical Information 1-24 Using DMI As 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 software applications, network cards, and printers. 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. Heceta Capabilities The computer has an Intel Heceta Head ASIC chip mounted on the system board. The purpose of this chip is to provide real-time monitoring capabilities used by DMI. The Heceta 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: Heceta 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. Heceta interrupts can be detected when out of range conditions occur. User prompts are displayed to alert the user of a potentially harmful condition.

The settings remain in memory even after you turn off the system power. To set the date, enter the current month, day, and year in mm/dd/yyyy format. To set the time, enter the current hour, minute, and seconds in hh:mm:ss, 24-hour format. For example, type 13:30:00 for 1:30 P.M. Diskette Drive This menu selects the type of diskette drive in your system. Unless you are changing your hardware, you do not need to change the diskette drive (floppy) A or B settings. If you add an optional 5 1/4-inch diskette drive to your system, select Floppy B and change the parameter to 1.2 MB, 5.25 inch. IDE Devices The hard disk drive (drive C:) shipped with some systems is configured as Primary IDE Master. This field reports the presence of an identification string supported by, up to four physical IDE drives (two on each PCI/IDE connector). If the cursor is placed on one of these fields and the field is selected by pressing the Enter key, the IDE Device Submenu appears. This submenu lets you set the drive parameters. Jumper settings on the IDE device must be set to the master or slave device (see the documentation that comes with the device).

58 2-14 Setup and Operation IDE Device Configuration Submenu The IDE Device Submenu lets you check or change the following hard disk drive parameters. IDE Device Configuration Number of Cylinders Number of Heads Number of Sectors Maximum Capacity IDE Translation Mode Multiple Sector Setting Fast Programmed I/O Modes IDE Device Configuration The system is shipped with the default as Auto Configured selected in this submenu. The system then automatically detects the hard disk type and sets the remaining parameters. If your IDE hard disk does not feature auto IDE type detection or your IDE hard disk was formatted on another system with parameters different than those reported by the drive, you need to select User Definable, and set the Number of Cylinders, Number of Heads, Number of Sectors, and Maximum Capacity. IDE Translation Mode The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry. Proper choice is dependent upon the drive s size, capabilities, and the operating system (OS) used. The following choices are available. Standard CHS is the translation mode that has been in use for years. Its use limits IDE capacity to a maximum of 528 MB regardless of the size of the drive used. Logical Block mode overcomes the 528 MB maximum size limitations imposed by the Standard CHS mode. It should be used only when the drive supports logical block addressing (LBA), and the OS supports LBA, or uses the BIOS to access the disk. Extended CHS mode also overcomes the 528 MB maximum size limitations imposed by the Standard CHS mode. It can be used with drives which are larger than 528 MB, but do not support the LBA mode.

59 Setup and Operation 2-15 Auto Detected (default) allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block mode if it is supported by the drive. The second choice is to utilize Extended CHS mode if the drive topology allows. If neither of the above two methods are possible, then Standard CHS mode is used. CAUTION: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive. If a drive is run in a mode other than the mode in which it was partitioned and formatted, unpredictable results may occur, including data loss. Different OS s have different abilities regarding IDE translation modes: UNIX does not currently support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in a different manner. OS/2 2.1 and OS/2 WARP can support LBA, ECHS, or Standard CHS methods. Note that LBA support may require a switch setting on an OS/2 drive in order to operate in the mode. OS/2 2.0 and Novell Netware can support either, ECHS or Standard CHS methods, but not LBA. DOS and Windows can support LBA, ECHS, or Standard CHS methods. If the Fast 32-bit IDE option of Windows is utilized, make sure to use the Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports this advanced geometry. You will get better performance not using Fast 32-bit IDE if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes. Language The installed language will appear in the Setup and BIOS text strings. English (US) is the default in the U. S. and Canada.

196 Appendix B Setting System Board Jumpers This chapter provides jumper setting information for configuring the system for a particular system requirement. Situations that require changing the jumper settings include the following: You are upgrading the processor. You have interrupted the Flash utility during a BIOS upgrade. You want to clear all customized CMOS settings back to the factory defaults. You want to deny access to the Setup utility. You forgot the password and cannot boot the system. You require more system resources. CAUTION: Jumpers are set correctly at the factory for the configuration. If the system requires a jumper change, change only the setting for that condition. Otherwise, keep the settings at their factory settings. CHANGING PROCESSOR JUMPER SETTINGS The following procedure explains how to locate and change the jumper setting when you upgrade the processor. WARNING: The system power must be off before changing a jumper setting. 1. Power off and unplug the system and any peripherals. 2. Remove the system unit cover (see Removing the Desktop Cover or Removing the Minitower Cover in Section 3). 3. Locate the following jumpers on the system board (see the following figure). You may have to remove any installed expansion boards to access the jumpers (see Removing Expansion Boards in Chapter 3).

197 B-2 Setting System Board Jumpers Figure B-1 Locating System Configuration Jumpers 4. Set the Processor/Bus Speed jumpers for the processor (see the following figure). Change the jumper setting by lifting the plastic block and placing it on the appropriate pins as shown in the following figure. NECCSD recommends using needle-nose pliers to move a jumper.
