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.

Basics Voltage Switch - 3 Voltage Switch Voltage Switch 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

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 SCS

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

Basics Peripheral Component Interconnect (PCI) Technology - 10 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 cannot be used in these expansion slots. PDS cards for the Macintosh LC family, the Macintosh Quadra 630 computer, or cards that operate in the I/O expansion slot in Power Macintosh 5200 and 6200 computers are not compatible

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 single- bank DIMMs. DRAM expansion slots 2 and 3 support both single-bank and dual-bank DIMMs. No DRAM is soldered on the logic board. Impo

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 l
