Processor
The PowerMate P series of computers use the following Pentium processors:
n PowerMate P150 — 150-MHz processor with an internal speed of 150 MHz and
an external speed of 60 MHz.
n PowerMate 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:
n all system memory, including 0 to 640 KB and all memory present above 1 MB
(see the following subsection for a system memory map).
n system 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:
n video text memory block from A0000 to BFFFF
n PCI memory space on top of main memory to 4 GB
n any 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.

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.
n Reduces CPU clock speed
The CPU, cache, and video clock speeds are reduced, putting the system in the
suspend mode.
n Blanks out the monitor
Puts the video controller into suspend mode. The vertical sync clock and blank
signals to the monitor are disabled.
n Forces 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:
n 1600 by 1200 pixels, 256 colors, vertical refresh rate of 60-78 Hz and a horizontal
refresh rate of 76-96 Kz
n 1280 by 1024 pixels, 256 colors, vertical refresh rate of 60-110 Hz and a
horizontal refresh rate of 63-107 Kz

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.

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.

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:
n Baud rate up to 19.2 KB per second
n Word length - 5, 6, 7, or 8 bits
n Stop bit - 1, 1.5, or 2 bits
n Start bit - 1 bit
n 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.
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.
