Preface

This manual contains technical information necessary for servicing and repairing the NEC PowerMate Professional 9000 Series minitower computer from NEC Computer Systems Division, Packard Bell NEC, Inc. It contains hardware and interface information for users who need an overview of system design. The manual also includes system setup information, procedures for installing options, and illustrated parts lists. The manual is written for NECCSD-trained customer engineers, system analysts, service center personnel, and dealers.

The manual is organized as follows: Section 1 — Technical Information provides an overview of computer features and

options, hardware design, interface ports, and internal devices. System specifications are listed including dimensions, weight, environment, safety compliance, power consumption, and memory.

Section 2 — Setup and Operation includes unpacking, setup, and operation information. Procedures are also included for configuring the system with the BIOS Setup utility, setting passwords, using power management and security features, reinstalling the operating system or software, and using the BIOS Update utility.

Section 3 — Option Installation provides installation procedures for adding optional expansion boards, additional storage devices, system memory, or a processor upgrade.

Section 4 — Maintenance and Troubleshooting includes recommended maintenance information, along with possible computer problems and their solutions, and the procedures for battery replacement. NECCSD telephone numbers are provided for obtaining service, accessing the NECCSD Bulletin Board System, and accessing the NEC FaxFlashSM service.

Section 5 — Repair includes computer disassembly and reassembly procedures. Also included are an exploded view diagram (Illustrated Parts Breakdown) and a parts lists for field-replaceable parts.

Appendix A — Connector Pin Assignments provides a list of system, riser, and option board internal connector pin assignments and a list of external pin assignments for the keyboard, mouse, serial ports, parallel port, network ports, and video port.

Appendix B —Jumper Settings provides jumper settings for the system board, and for options that may ship with the computer, including the CD-ROM reader and the fax/modem board.

A Glossary provides a list of definitions for many of the terms used in this manual.

1-12 Technical Information

Processor Subsystem

The system board supports a single or dual Intel Pentium II processor configuration with an internal clock speed of 233 MHz, 266 MHz, 300 MHz, or 333 MHz. Each processor uses Intel MMX technology.

NOTE:

that a terminator card be installed in the second processor slot (see “Processor Upgrades” later in this section).

The processor’s voltage ID pins automatically program the voltage regulator on the system board to the required processor voltage. The system board supports processors that have a 512-KB second-level cache and identical processor voltages. To ensure reliable operation, only Pentium II processors with fan/heatsinks can be installed on the DK440LX system board.

Single-processor configurations require

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 a unit (CPU subsystem) in Slot 1 on the system board.

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.

Processor Packaging

The processor is packaged in a Single Edge Contact (SEC) cartridge. The cartridge includes the processor core, second-level cache, thermal plate, and back cover. The processor connects to the system through the Slot 1 connector, a 242-pin edge connector mounted on the system board. When mounted in the Slot 1 connector(s), each processor is secured by the retention mechanism (RM) attached to the system board. For more information, see “Processor Upgrades” later in this section.

Second-Level Cache

To use the Pentium processor’s power, the system features an optimized 64-bit memory interface and 512 KB of second-level write-back cache on the processor.

The second-level cache is located on the substrate of the SEC cartridge. The cache includes burst pipelined synchronous static RAM (SBRAM) and tag RAM. The cache consists of four BSRAM components totaling 512 KB in size. A maximum of 512 MB of system memory is cacheable. ECC or non-ECC support is provided in the cache.
