Technical Information 1-7
Processor and Secondary Cache
The PowerMate Professional uses a Pentium II processor with an internal clock speed of 233 MHz or 266 MHz. The external speed of the 233-MHz and 266-MHz processors is 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 II processor’s power, the system features an optimized 64-bit memory interface and 512 KB of secondary write-back cache incorporated into 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 contained on a Single Edge Contact (S.E.C.) cartridge that plugs into the system board at Slot 1, which is a 242-pin edge connector. The processor subsystem consists of the following components:
Tprocessor card (including the processor and secondary cache)
Tthermal plate
Tback cover.
When the processor subsystem is mounted in Slot 1, it is secured by a retention mechanism (RM) attached to the system board. The RM acts as an insertion guide and prevents movement of the processor after installation. The processor heatsink is also stabilized by supports that attach to the motherboard.
System BIOS
The system BIOS is from Intel/American Megatrends Incorporated (AMI) and provides ISA and PCI compatibility. The BIOS is contained in a 2-MB 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 onboard DRAM instead of from the slower 8-bit flash device.
NEC’s Flash ROM allows fast, economical BIOS upgrades. NEC Flash ROMs are reprogrammable system and video EPROMs. With NEC’s Flash ROM, a ROM BIOS change is expedited in the following ways:
Tis fast and easily done using a Flash utility
Teliminates the expensive replacement of ROM BIOS chips, and reduces system maintenance costs
1-8 Technical Information
Treduces inadvertent system board damage that can take place when replacing ROMs
Tfacilitates adopting new technology while maintaining corporate standards
Tgives network administrators 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 disks, communication devices, and peripherals. The system BIOS also contains the Setup utility. The hardware setup 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 shown in Table 1-3.

Configurations ship with 32 MB or 64 MB of memory: 640 KB of base memory and 31 MB or 63 MB of extended memory. System memory can be expanded up to 256 MB using optional single in-line memory modules (SIMMs) installed in SIMM sockets on the system board.
The memory configuration consists of two banks (bank 0 and bank 1) with two sockets each. The memory sockets accept 32-bit, 60-ns for faster, 4-, 8-, 16-, 32-, or 64-MB SIMMs. The sockets accept Extended Data Out (EDO) mode or Fast Page (FM) mode SIMMs and support parity, non-parity, or error checking and correction (ECC).
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, four 64-MB SIMMs may be installed for a total of 256 MB.
CAUTION: SIMMs must match the tin metal plating used on the system board SIMM sockets. When adding SIMMs, use tin-plated SIMMs only.
Technical Information 1-11
SIMMs install directly in the four sockets on the system board. The four sockets are assigned as Bank 0 (2 sockets) and Bank 1 (2 sockets). All configurations have two SIMMs installed in Bank 1.
SIMMs must be installed in pairs of the same memory type and size. Both sockets must be populated within a bank for the system to work. No switch or jumper settings are required when the memory is changed. The system BIOS automatically detects the SIMMs. See “Checking the Memory in the System” in Section 3 for the valid configurations.
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, and 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 1-5. Interrupt-level assignments 0 through 15 are listed in order of decreasing priority. See Section 2, “Setup and Operation,” for information on changing the interrupts using Setup.

*These interrupts are selected and used by the installed expansion boards.
Plug and Play
The system comes with a Plug and Play BIOS that 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.
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 II processor. The bus supports burst modes that send large chunks of data across the bus, allowing fast displays of high-resolution images.
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.
PCI expansion slot connector pin assignments are provided in Appendix A.
Technical Information 1-13
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 that supports PIO Mode 4 devices with 16 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. In multimedia configurations, the installed CD-ROM reader is connected to the secondary PCI/IDE port.
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. This increases 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 1-6.
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. This connector is located at the rear of the system unit. Pin locations for the parallel interface connector are given in Appendix A.
1-14 Technical Information
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 IR interface (see Table 1-7). The buffered high-speed serial ports support transfer rates up to 19.2 KB. These ports allow the installation of high-speed serial devices for faster data transfer rates.
I/O addresses and interrupt levels for the two channels are given in Table 1-7. 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.
