System Overview - 1 |
|
|
|
|
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.
Basics Power Macintosh 4400/200, 7220/200 - 2
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

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. |

Key Commands - 7 |
|
|
|
|
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:

CD-ROM and Hard Drive Interface - 8 |
|
|
|
|
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.

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.

Dual In-Line Memory Modules (DIMMs) - 11 |
|
|
|
|
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.
Important: The single in-line memory modules (SIMMs) used in previous Macintosh models are not compatible with 4400 models. Don’t use DIMMs that support a 4K refresh rate. Use 168-pin, 3.3 V unbuffered EDO, 60 ns or faster DIMMs. Also, the JEDEC MO-161 specification shows three possible heights for the EDO DIMM. For Macintosh
Basics |
Dual In-Line Memory Modules (DIMMs) - 12 |
|||
|
|
|
||
|
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
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
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 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.
