Processor and Secondary Cache

The PowerMate Pro2200 uses a 200-MHz Pentium processor with an internal clock speed of 200 MHz. The PowerMate Pro2180 uses a 180-MHz Pentium processor with an internal clock speed of 180 MHz. (The external speed of the 200-MHz processor is 66 MHz, while the 180-MHz processor has an external speed of 60-MHz.)

Each processor has 16 KB of write-back primary cache and a math coprocessor. The 16 KB primary cache provides 8 KB for instructions and 8 KB for data.

1-6 Technical Information

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 Pro processor’s power, the system features an optimized 64-bit memory interface and 256 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™, and Pentium Pro processors. The Pentium Pro processor is mounted into a socket-8 zero insertion force (ZIF) socket. The socket provides an upgrade path to the next generation processor.

System BIOS

The system BIOS is from American Megatrends Incorporated (AMI), which provides ISA and PCI compatibility. The BIOS is contained in a flash memory device on the system board (2-MB Intel PA28FB200BX). 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.

NECCSD’s Flash ROM allows fast, economical BIOS upgrades. NEC Flash ROMs are reprogrammable system and video EPROMs. With NECCSD’s Flash ROM, a ROM BIOS change:



is fast and easily done using a Flash utility



eliminates the expensive replacement of ROM BIOS chips, and reduces system maintenance costs



reduces inadvertent system board damage that can take place when replacing ROMs



facilitates adopting new technology while maintaining corporate standards



gives 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 of the PowerMate Pro2200/2180 Service and Reference Manual for further information on the BIOS Update utility). The Flash ROM supports the reprogramming of the system BIOS and the video BIOS.

System Memory

Configurations ship with 16 MB of memory (32 MB in the SCSI configuration): 640 KB of base memory and 15 MB (31 MB in the SCSI configuration) 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 SIMM memory sockets accept 32-bit (non-parity) 4-, 8-, 16-, 32-, or 64-MB, 60 ns, Extended Data Out (EDO) mode SIMMs.

NOTE:

64-MB SIMMs have not been qualified for use, but they will be supported by the system board when they become available.

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.

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. SIMM banks can be populated in either order.

1-10 Technical Information

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 jumpers required setting when the memory is changed. The system BIOS automatically detects the SIMMs. See “Checking the Memory in the System” in Section 3 of the PowerMate Pro2200/2180 Service and Reference Manual 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 1-4. Interrupt-level assignments 0 through 15 are in order of decreasing priority. See Section 2 of the PowerMate Pro2200/2180 Service and Reference Manual for information on changing the interrupts using the Setup Utility.

Technical Information 1-11

The PowerMate Pro2200/2180 multimedia models and SCSI multimedia models do not have any free IRQs. Disable the USB connectors to add an additional adapter.

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.

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 of the PowerMate Pro2200/2180 Service and Reference Manual.

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 Pro 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 Pro’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.

PCI expansion slot connector pin assignments are provided in Appendix A of the PowerMate Pro2200/2180 Service and Reference Manual.

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 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.

1-12 Technical Information

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 1-5.

NOTE:

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 of the PowerMate Pro2200/2180 Service and Reference Manual.

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 1-6). 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.

Technical Information 1-13

I/O addresses and interrupt levels for the two channels are given Table 1-6. 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.

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.
