Basics System Overview - 1
System Overview
The Power Macintosh 4400 is an entry-level computer with
a PowerPC 603e processor. The adapter card in the
4400/160 allows installing three PCI cards. In later
models the adapter card allows installing one
communications card and two PCI cards.
The computer can be turned on or off from the keyboard and
from the power button. A voltage switch allows manual
selection of two settings for voltage ranges of
100–130V or 200–230V.

Power Macintosh 4400/200, 7220/200
The Power Macintosh 4400/200 will be sold worldwide. In
the Far East, it will be named 7220/200. These computers
have the same features as the Power Macintosh 4400/160,
with these exceptions:
• Communications slot II on the PCI adapter card
• Two PCI card slots on the PCI adapter card
• 200 MHz processor clock
• Maximum memory expansion of 160 MB

The voltage switch must be
set correctly to avoid
damaging the computer.
Insert a screw driver in the
slot to set the switch to show
“115” for voltages between
100 and 130. Set the switch
to show “230” for voltages
between 200 and 230. Some
countries use two
standardized voltages. If you
aren’t sure which voltage is
available, check with the
electricity supply company
before plugging in the
computer.

Basics Key Commands - 7
Key Commands
Since there are no programmer’s switches on the Power
Macintosh 4400, the reset and interrupt functions require
pressing key combinations. There are two power buttons on
the 4400, one on the keyboard and one on the front of the
computer (see the Front View diagram later in this
chapter). The keyboard power key is identified by a triangle
imprinted on it.
Press these key combinations for at least one second while
holding down the power key found on the keyboard:

Basics CD-ROM and Hard Drive Interface - 8
CD-ROM and Hard Drive Interface
The internal hard drive uses intelligent device electronics
(IDE) technology, commonly used in DOS-compatible
systems. The IDE drive uses the standard advanced
technology attachment (ATA) or IDE interface. The IDE hard
drive functions the same as a typical SCSI hard drive. You
must replace IDE drives like for like. The IDE drive does not
affect SCSI ID selections or SCSI termination schemes. Seven
external SCSI devices may be daisy-chained through the
external SCSI port.
The CD-ROM drive uses the advanced technology adapter
peripheral interface (ATAPI), not SCSI. The ATA and ATAPI
interface schemes could be incompatible with some disk
utility programs.
Basics Peripheral Component Interconnect (PCI) Technology - 9
Peripheral Component Interconnect
(PCI) Technology
The Power Macintosh 4400 offers peripheral component
interconnect (PCI) expansion. Because the PCI bus is an
industry standard, most existing PCI 2.0-compliant cards
(with the addition of a Macintosh OS-specific software
driver) will work in these computers.
PCI offers significantly higher performance than the NuBus
architecture used in previous Macintosh models. Running at
33 MHz, the PCI bus is up to three times faster than NuBus,
offering overall enhanced system performance, particularly
in the areas of video and networking.
PCI expansion cards are mounted horizontally in an adapter
card.

Note:
The Power Macintosh PCI adapter card expansion slots
are compatible with all PCI 2.0 specification-compliant
cards with the addition of a Macintosh-OS-specific software
driver. Nubus cards

Basics Dual In-Line Memory Modules (DIMMs) - 11
Dual In-Line Memory Modules (DIMMs)
The Power Macintosh 4400 uses DRAM on dual in-line
memory modules (DIMMs). Three slots allow for memory
expansion up to 96 MB using 3.3 V unbuffered 8-byte
extended data output (EDO) JEDEC-standard 168-pin DRAM
DIMM cards. DRAM expansion slot 1 only supports singlebank DIMMs. DRAM expansion slots 2 and 3 support both
single-bank and dual-bank DIMMs. No DRAM is soldered on
the logic board.

computers, use only the shortest of the three (1.100
inches). Taller DIMMs put excessive pressure on the DIMM
sockets due to mechanical pressure inside the case.
The DIMMs can be installed one or more at a time. In the
4400/160 each DIMM slot can support up to a 32 MB bank
of memory. In the 4400/200 and 7220/200, the first
DIMM slot supports up to a 32 MB bank and the other two
support up to 64 MB in each. The logic board supports only
linear memory organization. The combined memory of all of
the DIMMs installed will be configured as a contiguous
memory space.
Basics Video RAM - 13
Video RAM
The logic board has a 120-pin video DIMM connector that
allows the use of EDO RAM. The video controller supports the
following for video memory:
• 1 or 2 MB of EDO RAM
• 1, 2, or 4 MB of SGRAM
PC Compatibility Cards
Apple computer offers PC Compatibility Card upgrade kits
that bring full DOS functionality to the Power Macintosh
4400 computers. The cards plug into any available PCI slot
on the logic board. Refer to the PC Compatibility Card
manual on this Service Source CD for more information and
installation instructions.
Basics GeoPort Technology - 14
GeoPort Technology
Geoport is a hardware and software communications
architecture that has been optimized for computertelephony integration. It has three main attributes:
• It lets any GeoPort-compatible computer connect to any
telephone (analog or digital, public or private)
anywhere in the world.
• Once connected, it supports an arbitrary number of
independent data streams up to a total bandwidth of
2 MB/second.
• Unlike traditional asynchronous data communications
(such as AppleTalk), GeoPort also supports isochronous
data streams (such as real-time voice and video) and
provides the real-time application program interfaces
(APIs) necessary to hide the implementation details
from both the recipient and the sender.
