nPowerMate P150 and P166 hard disk systems (diskette drive, hard disk)

nPowerMate P150 and P166 multimedia systems (diskette drive, hard disk, six-speed CD-ROM reader, multimedia components).

All systems come standard with an Intel Pentium™ processor (150 MHz or 166 MHz), a 3 1/2-inch diskette drive, 256 kilobyte (KB) synchronous secondary cache, 16-megabytes (MB) of random access memory (RAM), and 2 MB of video window random access memory (WRAM). Each system incorporates power management features and has factory installed software including Microsoft Windows for Workgroups™ or Microsoft ® Windows 95™.

The following paragraphs provide an overview of the system.

MINITOWER SYSTEM CHASSIS

The minitower chassis provides an enclosure for the system board, power supply, five useable expansion slots, a six-connector PCI/ISA backboard, and five storage device slots. The expansion slots include three 8-/16-bit ISA slots, one shared PCI/ISA slot, and one 32bit PCI slot.

A video board (the Matrox Millennium™ board described in "Graphics Subsystem") occupies one of the expansion slots to provide graphics and/or video functionality.

The five storage device slots accommodate up to four accessible devices and one internal hard disk drive device. The accessible devices include the standard one-inch high 3 1/2-inch 1.44-MB diskette drive and up to three 1.6-inch high 5 1/4-inch storage devices. The internal device slot supports the standard 1-inch by 3 1/2-inch hard disk.

The non-multimedia hard disk systems ship with an accessible 3 1/2-inch diskette drive and an internal 3 1/2-inch hard disk drive, leaving three accessible 5 1/4-inch storage device slots available for optional devices. The multimedia systems ship with an accessible 3 1/2- inch diskette drive, an internal 3 1/2-inch hard disk drive, and an accessible 5 1/4-inch CDROM reader, leaving two accessible 5 1/4-inch storage device slots.

Processor

The PowerMate P series of computers use the following Pentium processors:

nPowerMate P150 — 150-MHz processor with an internal speed of 150 MHz and an external speed of 60 MHz.

nPowerMate P166 — 166-MHz processor with an internal speed of 160 MHz and an external speed of 66 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.

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 synchronous 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 secondary cache, external to the processor. The cache uses 15-ns SRAM that allows data to be sent or received from the 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.

The cache is connected directly to the processor address bus and uses physical addresses. A bus feature known as burst enables fast cache fills. Memory areas (pages) can be designated as cacheable or non-cacheable by software. The cache can also be enabled and disabled by software.

The write strategy of the cache (primary and secondary) is write-back. If the write is a cache hit, an external bus cycle is not generated and information is written to the cache. The system caches the following regions:

nall system memory, including 0 to 640 KB and all memory present above 1 MB (see the following subsection for a system memory map).

nsystem and integrated video controller in BIOS

1-6 Technical Information

Non-cacheable portions of memory are defined by software (see the following subsection for a system memory map). The system does not cache the following regions:

nvideo text memory block from A0000 to BFFFF

nPCI memory space on top of main memory to 4 GB

nany access to the PCI or AT bus

The cache can be cleared by software instructions.

System and Video BIOS

The system and video BIOS are stored in a 1 MB (128 KB by 8) flash memory device (Flash ROM). The system BIOS uses 64 KB, the video BIOS uses 32 KB, and 32 KB is reserved. 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.

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 in shown in Table 1-2.

Power Management

Each system incorporates power management features that lower power consumption when there is no activity detected from the keyboard, mouse, diskette drive, CD-ROM reader, or hard disk drive after a pre-defined period of time. As soon as activity is detected the system resumes where it left off.

With Power Management enabled (shipped enabled), the system automatically activates the power-saving features and enters a suspend mode whenever inactivity is sensed. The system's power-saving functions are as follows.

nReduces CPU clock speed

The CPU, cache, and video clock speeds are reduced, putting the system in the suspend mode.

nBlanks out the monitor

Puts the video controller into suspend mode. The vertical sync clock and blank signals to the monitor are disabled.

nForces the IDE devices into stand-by mode

A suspend command is sent to the IDE devices which put the devices into a stand-by mode.

I/O Addressing

The processor communicates with I/O devices by I/O mapping. The hexadecimal (hex) addresses of I/O devices are listed in Table 1-3.

System Memory

All systems come standard with 16 MB of EDO memory: 640 KB of base memory and 15 MB of extended memory. System memory can be expanded up to 128 MB, using optional single in-line memory modules (SIMMs) installed in SIMM sockets on the system board.

Four SIMM sockets are integrated on the system board. The multimedia and 1.2-/2.0-GB hard disk configurations ship with two 2 MB x 32 SIMMs) (16 MB total) installed in two sockets.

The SIMM memory sockets accept 32-bit (non-parity) 4-, 8-, 16-, or 32-MB 60 ns or 70 ns 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), and 8 MB x 32 bit (32 MB). When the standard SIMMs are removed, four 32-MB SIMMs may be installed for a total of 128 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 SIMM 1 through SIMM 4. The two standard 8 MB SIMMs are installed in SIMM 1 and SIMM 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. SIMM banks 1 and 2 must always be filled for the system to operate. Table 1-4 shows the SIMM memory upgrade path.

Interrupt Controller

The interrupt controller operates as an interrupt manager for the entire AT 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 in order of decreasing priority. See Section 2, Setup and Operation, for information on changing the interrupts using Setup.

Graphics Subsystem

The system unit has a Matrox MGA Millennium motion video controller and graphics accelerator integrated on the video board. The video board plugs into the PCI backplane. State of the art techniques are used for optimizing performance in computer graphic intensive applications and graphical user interfaces (GUI).

The integrated graphics controller integrates a motion video controller, a high-performance GUI accelerator, 24-bit high frequency DAC and clock generator, VESA® -compliant feature connector, and 2 MB of fast 64-bit WRAM (expandable using optional upgrade modules).

Motion Video Controller

The motion video controller integrates a powerful Windows® GUI engine and unique motion video playback hardware for superior performance. The graphics engine includes an on-chip color space converter to accelerate decompression and a hardware scaler to scale continuously from native size up to full screen at full speed. The graphics engine delivers a full screen, smooth display of motion video data up to 30 frames per second (fps). Support includes MPEG-1 and Video for Windows® .

1-12 Technical Information

MPEG is a compression/decompression standard developed by the Motion Picture Experts Group. MPEG produces full-screen 30 fps, broadcast-quality digital video. The video controller architecture maximizes the motion video performance and removes bandwidth bottlenecks to display multimedia data at its full speed.

Graphics Accelerator

The graphics accelerator is specifically designed for graphics-intensive operations, text and color pixel amplification, and scrolling. The graphics accelerator provides 64-bit, ultra-high performance for demanding True Color, High Color, and pseudocolor GUI and CAD applications.

The accelerator minimizes bus traffic by off-loading the tasks normally performed by the processor. The dedicated bit-block transfers (BitBLT) engine maximizes performance by speeding the movement of large blocks of image data in video memory.

Video Memory

The system comes with 2 MB of on-board video WRAM, upgradeable to 8 MB. The standard 2 MB WRAM consists of two devices soldered to the system board. The optional 2 MB or 6 MB of WRAM is mounted on a daughter card that installs in two sockets on the video board. You can install one or the other type card (2-MB or 6-MB).

With the standard 2 MB of video WRAM, the video hardware supports the following resolutions, colors, and refresh rates:

n1600 by 1200 pixels, 256 colors, vertical refresh rate of 60-78 Hz and a horizontal refresh rate of 76-96 Kz

n1280 by 1024 pixels, 256 colors, vertical refresh rate of 60-110 Hz and a horizontal refresh rate of 63-107 Kz

n1152 by 882 pixels, 256/16.5K colors, vertical refresh rate of 60-120 Hz and a horizontal refresh rate of 54-110 Kz

n1024 by 768 pixels, 256/65K colors, vertical refresh rate of 60-120 Hz and a horizontal refresh rate of 48-104 Kz

n640 by 480 pixels, 256/65K/16.7 million colors, vertical refresh rate of 60-200 Hz and a horizontal refresh rate of 32-100 Kz.

Technical Information 1-13

With 4 MB or 8 MB of video WRAM, the system supports the following additional resolutions, colors, and refresh rates:

n1600 by 1200 pixels, 256/16.5K colors, vertical refresh rate of 60-78 Hz and a horizontal refresh rate of 76-96 Kz

n640 by 480 pixels, 256/65K/16.7 million colors, vertical refresh rate of 60-200 Hz and a horizontal refresh rate of 32-100 Kz.

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.

1-14 Technical 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 systems only) is connected to the secondary PCI/IDE port. Both devices are configured as “masters” off the IDE controller.

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 1-6.

NOTE: Any interrupts used for the built-in parallel port are not available for ISA parallel ports.

			Technical Information 1-15

	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 IR interface (see Table 1-7). 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.

I/O addresses and interrupt levels for the two channels are given 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.

Table 1-7 Serial Port Addressing and Interrupts

Starting I/O Address	Interrupt Level	Port
3F8h	IRQ04	COM1*
2F8h	IRQ03	COM2**
3E8h	IRQ04	COM3
2E8h	IRQ03	COM4

*Disabled if fax/modem installed

**Used for IrDA data transfer

1-16 Technical Information

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, Setup and Operation, for information on resetting the port through Setup.

Serial interface specifications include:

nBaud rate up to 19.2 KB per second

nWord length - 5, 6, 7, or 8 bits

nStop bit - 1, 1.5, or 2 bits

nStart bit - 1 bit

nParity 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.

Infrared Interface

The I/O controller incorporates an infrared interface that provides two-way wireless communication through the IR window (port) on the front of the system. The interface uses infrared as the transmission medium instead of a traditional serial cable.

The IR port permits transfer of files to or from portable devices such as laptops and personal digital assistant (PDA) products using the pre-installed Puma TranXit 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 IR 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 system. 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. Connector locations are given in Appendix A.
