To install Mac OS 9: 1 Back up your important files, if possible. 2 Insert the Mac OS X Install Disc 2 that came with your computer. 3 Double-click Install Mac OS 9 System Support. 4 Follow the onscreen instructions. 5 Select the destination disk for installation and continue following the onscreen instructions.

Maximizing Ethernet Performance
Your computer performs best when the Ethernet port to which it is connected is set to auto-negotiate. Ask your network administrator to verify this setting. Important: If you experience connection problems on your network, make sure your network switch is set to auto-negotiate, if possible. If a switchs port is not autonegotiating, your computer detects the appropriate speed but defaults to half-duplex mode. If the switchs port at the other end of the link is configured for full-duplex mode, a large number of late events can occur on the link. If it isnt possible to set the switch to auto-negotiate, then set the switchs port to half-duplex. For more information, see the documentation that came with the Ethernet switch.
Note: If you connect your computer directly to a configurable Ethernet switch, have your network administrator disable spanning tree on that port. Otherwise your computer may duplicate the AppleTalk address of another computer on the same network and both network connections may become unreliable.
Locating Your Product Serial Number
System Profiler shows the serial number of your computer. Open System Profiler (in Applications/Utilities) and click the System Profile tab. The serial number of your Power Mac G5 is also on the configuration label, which is located inside the side panel, directly below the air deflector.

Important Ergonomic and Health-Related Information
Here are some guidelines for adjusting the furniture in your office to reduce glare and to accommodate your physical size and shape. An adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so your thighs are tilted slightly and your feet are flat on the floor. The back of the chair should support your lower back (lumbar region). Follow the manufacturers instructions for adjusting the backrest to fit your body properly. When you use the computer keyboard, your shoulders should be relaxed. Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line. You may have to raise your chair so that your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you can lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray thats lower than the regular work surface. Position the mouse at the same height as your keyboard. Allow adequate space to use the mouse comfortably.
Arrange the display so that the top of the screen is slightly below your eye level when youre sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm). Position the display to minimize glare and reflections on the screen from overhead lights and nearby windows. If possible, use a tiltable display stand. The stand lets you set the display at the best angle for viewing, helping to reduce or eliminate glare from lighting sources you cant move.

4570 cm (1828 in.)

Quad-Core Processing

Enter the dual-core PowerPC G5 processor: one silicon chip with two independent processor cores. Now take two of those dual-core chips and you have the Power Mac G5 Quad, for groundbreaking quad-core processing. Quad-core processing means more 64-bit resources: more L2 cache, more Velocity Engine units, and more double-precision oating-point units. Videographers can edit more footage, lmmakers can produce more real-time eects, designers and photographers can process more higher-resolution images, and researchers can crunch through data sets for faster results. Compare a quad-core Power Mac G5 to the fastest dual-processor G5 ever built, and youll experience up to 69 percent faster performance running popular professional applications.1

With two independent cores on one processor, the new PowerPC G5 packs tremendous processing power on a single chip.
Two Dual-Core PowerPC G5 Processors
The new PowerPC G5 combines two processor cores on a single silicon chip, providing double the computational power in the same space as a single-core processor. Whats more, each core has its own 1MB of L2 cache memorydouble the size of its predecessorso youll have ultrafast access to twice the amount of frequently used data. With two dual-core PowerPC G5 processors, the Power Mac G5 Quad doubles the ante. Applications can take advantage of four 64-bit processor cores, including four 1MB L2 caches, four 128-bit Velocity Engine units, and eight double-precision oating-point units, for a radical increase in desktop performance. Comparison of PowerPC G4, single-core PowerPC G5, and dual-core PowerPC G5 processors
PowerPC G4 Architecture Addressable memory Frontside bus Processor cores Velocity Engine units Floating-point units Integer units L1 data cache L1 instruction cache L2 cache 32-bit 4 gigabytes Single One One One One 32K 32K 256K Single-core PowerPC G5 64-bit 4 terabytes Dual One One Two Two 32K 64K 512K Dual-core PowerPC G5 64-bit 4 terabytes Dual Two Two Four Four Two sets of 32K Two sets of 64K Two sets of 1MB
Bidirectional Frontside Bus
Leveraging the dual frontside bus architecture pioneered in the original Power Mac G5, each dual-core processor has an independent data path to the system controller running at up to 1.25GHz. Unlike conventional processor interfaces, which carry data in only one direction at a time, this dual-channel frontside bus has two 32-bit pointto-point links (64 bits total): One link travels into the processor and another travels from the processor, which means no wait time while the processor and the system controller negotiate which will use the bus or while the bus switches direction. This enables data to move in opposite directions simultaneouslya dramatic improvement over previous processor interfaces.
In Power Mac G5 Quad systems, each dual-core PowerPC G5 processor has its own bidirectional frontside bus.
In Power Mac G5 Quad systems, each processor has its own bidirectional interface to the system controller, unlike traditional dual-processor systems, which constrain throughput by placing all processor resources on one bus. Each G5 processor has a dedicated interface to main memory for total bandwidth of up to 10 GBps per processor, or a total of 20 GBps for a quad system. This high-performance frontside bus architecture also enables each core to discover and access data in the other cores cachesfurther increasing performance on quad-core systems.

64-Bit Processor Architecture
The dual-core PowerPC G5 joins forces with Mac OS X v10.4 Tiger to enable 64-bit computation, including the ability to address vast amounts of main memory and to perform double-precision oating-point calculations. Support for massive amounts of memory The move to 64-bit processors results in a dramatic leap in the amount of memory supported. In practice, memory addressing is dened by the physical address space of the processor. The PowerPC G5, with 42 bits of physical address space, supports a colossal 242 bytes, or 4 terabytes (4TB), of system memory. Although its not currently feasible to purchase 4TB of RAM, the advanced architecture of this processor allows for plenty of growth in the future. More practical and still far more than a typical PC, the Power Mac G5 can be congured with 16GB of addressable memory. Such large quantities of memory enable the system to contain a complex 3D model, massive digital images, a scientic simulation, or a sequence of video entirely in RAM. When data is stored in memory, the processor can access it 40 times faster than from the hard drive, drastically reducing the time to manipulate, modify, and render the data and making it feasible to tackle gigantic projects on a desktop system. 64-bit computation power The other advantage provided by the 64-bit PowerPC G5 is the ability to perform multiple simultaneous 64-bit oating-point and integer calculations. The PowerPC G5 features full 64-bit data paths and data registers, allowing it to express the extreme precision needed for oating-point mathematics and to express integers up to 18 billion billion. By contrast, a 32-bit processor must break these types of computations into multiple piecesrequiring multiple passes through the processor and slowing down application performance.
Eight Double-Precision Floating-Point Units
Linpack A measure of a computers oating-point execution performance, the Linpack benchmark solves a dense system of linear equations. The Power Mac G5 Quad executed the double-precision equations 88 percent faster than the dual 2.7GHz Power Mac G5 and an amazing 626 percent faster than the dual 1.42GHz Power Mac G4.
Power Mac G5 Quad 2.5GHz Dual 2.7GHz Power Mac G5 Dual 1.42GHz Power Mac G4 2.9 gigaops 11.1 gigaops 21 gigaops

The PowerPC G5 core contains two double-precision oating-point units, each capable of performing a multiply and an add at the same time. This means a Power Mac G5 Quad, with four processor cores and a total of eight oating-point units, can complete up to sixteen 64-bit oating-point operations in a single cycle. Such immense 64-bit computational power accelerates applications in many elds, including audio creation, 3D content creation, and scientic visualization and analysis resulting in performance levels far beyond those of previous Power Mac generations. Fused multiply-add example The oating-point units in the PowerPC G5 can complete both a multiply and an add operation as part of the same machine instructionaccelerating matrix multiplication, vector dot products, and other scientic computations. Referred to as fused multiplyadd, or fmadd, this instruction is considered a building block for data-intensive oating-point computation. The following computation can be completed by a fused multiply-add instruction in one pass through either of the two oating-point units in a PowerPC G5 core: T = (a * b) + c On other processors, two instructions are required. The rst is a multiply instruction: U = (a * b) The product U is used by a second instruction, an addition, to complete the computation: V=U+c In processors with comparable clock speeds, the computation of (a * b) + c is completed twice as fast using fused multiply-add. It also delivers a more accurate result, because round-o occurs just once in the computation of Twhile on other processors, round-o occurs twice: in the computation of U and in the computation of V.
Four Velocity Engine Units
Gigaops The gigaops test indicates a systems vector processing capability by measuring the maximum number of oating-point operations it can perform. With four Velocity Engine units, the Power Mac G5 Quad completed the test 85 percent faster than the dual 2.7GHz Power Mac G5 and 260 percent faster than the dual 1.42GHz Power Mac G4.
Power Mac G5 Quad 2.5GHz Dual 2.7GHz Power Mac G5 Dual 1.42GHz Power Mac G4 21.3 gigaops 76.6 gigaops 41.1 gigaops
A dual-pipelined Velocity Engine in each processor core is optimized with two independent queues and dedicated 128-bit registers and data paths for ecient instruction and data ow. This 128-bit vector processing unit accelerates data manipulation by applying a single instruction to multiple data at the same time, known as SIMD processing. Originally implemented in the PowerPC G4, the Velocity Engine in the PowerPC G5 uses the same set of 162 instructions, enabling it to accelerate existing Mac OS X applications that have been optimized for the Velocity Engine. Vector processing is useful for transforming large sets of data, such as manipulating an image or rendering a video eect. For example, when a designer uses a lter to apply a motion blur to an image, each pixel of the image must be changed according to the same set of instructionsa highly repetitive processing task. Each Velocity Engine pipeline speeds up this task by processing up to 128 bits of data, in four 32-bit integers, eight 16-bit integers, sixteen 8-bit integers, or four 32-bit single-precision oating-point values, in a single clock cycle. That works out to 16 simultaneous 32-bit oating-point operations on a Power Mac G5 Quad.

Three expansion slots In addition to the 16-lane graphics slot, the Power Mac G5 features three PCI Express expansion slots: two four-lane slots and one eight-lane slot. Each slot uses a standard connector that can accommodate a card of any size. This means a four-lane card works perfectly in an eight-lane slot. If the card has more lanes than the slot, the card adjusts to the bandwidth available and downshifts to that data rate. With the high-bandwidth architecture in the new Power Mac G5, your system not only will achieve faster performance today, but will be ready for future technologies as well. For example, 10-gigabit networking technology, which can achieve up to 2.5 GBps of data throughput, will require an eight-lane slot. This promises to be an ideal solution for working with uncompressed HD video, which demands over 120 MBps per individual streamand far more in a multiple-stream or multiple-camera environment.
Each Power Mac G5 system includes four PCI Express slots.
Support for up to eight displays Because both graphics and expansion slots use the same PCI Express standard, you can install a PCI Express graphics card in any PCI Express slot. That means a single Power Mac G5 can support four, six, or even eight displays with the addition of multiple NVIDIA GeForce 6600 graphics cards.
Two independently congurable 10/100/1000BASE-T (Gigabit) Ethernet interfaces deliver tremendous networking bandwidth. Each Gigabit Ethernet controller in the new Power Mac G5 supports jumbo frames (packets of up to 9000 bytes), reducing system overhead and increasing throughput for all network activities. Virtual LAN tags (VLAN 802.1q) allow the Power Mac G5 to join multiple virtual networks, with a unique identication for each one. And with Ethernet link aggregation in Mac OS X, you can combine the bandwidth of the interfaces for doubled performance. Dual Gigabit Ethernet delivers the massive throughput required for many professional networking needs. Youll be able to support an isolated management network thats independent of a client services network, work in a SAN environment that requires independent networks for metadata and general networking, or provide the highspeed network interconnect required in many cluster computing environments.

High-Performance I/O

The Power Mac G5 architecture uses the HyperTransport protocol to integrate I/O subsystems and connect them to the system controller. Serial ATA, FireWire, USB, audio, and wireless technologies are integrated through two bidirectional 800MHz HyperTransport interconnects for a maximum throughput of 1.6 GBps, providing ample throughput for a host of peripheral devices. Serial ATA storage Serial ATA is the industry-standard storage interface, replacing the Parallel ATA interface. Designed to keep pace with the demands of digital video creation and editing, audio storage and playback, and other data-intensive applications, Serial ATA supports 1.5-Gbps throughput per channel (equivalent to a data rate of 150 MBps). The Power Mac G5 can hold two internal 500GB Serial ATA drives for a total capacity of 1TB of storage.2 Each drive is on an independent bus, so theres no competition for drive performance as with Parallel ATA. Performance is improved even further when drives are striped using software RAID in Mac OS X.

FireWire and USB 2.0 One of the most versatile standards ever developed, FireWire makes it easy to connect high-bandwidth devices such as DV cameras, hard drives, and high-performance imaging peripherals. And since FireWire cables carry power, the Power Mac G5 can recharge a portable devices batteries, even while its in use. FireWire 800 doubles the throughput of the original FireWire 400, from 400 to 800 Mbps.4 The FireWire 800 port can also connect to FireWire 400 devices using the appropriate 9-pin-to-6-pin or 9-pin-to-4-pin cable. Whats more, FireWire 800 works over distances of up to 100 metersperfect for remote devices. USB ports allow you to connect printers, scanners, graphics tablets, keyboards, microphones, iPod players, speakers, joysticks, and other industry-standard input and output devices. Each system has one FireWire 400 port on the front, one FireWire 400 port on the back, a FireWire 800 port on the back, and four USB 2.0 portsone on the front and three on the backplus two USB 1.1 ports on the keyboard. Wireless connections For wireless communications, an antenna is built into the Power Mac G5just add optional AirPort Extreme and Bluetooth technologies. AirPort Extreme allows you to create an ad hoc network, share les with a wireless-enabled portable computer, or stream music to your stereo using an AirPort Express Base Station.3 Bluetooth 2.0 + EDR (Enhanced Data Rate) allows short-range wireless connectionsat data rates up to 3 Mbpsto a variety of Bluetooth-enabled digital devices, such as cell phones, personal digital assistants, printers, and Apples wireless keyboard and mouse. You can even synchronize contacts between Bluetooth-equipped cell phones, PDAs, and Mac OS X Address Book. For more information, see www.apple.com/airport and www.apple.com/bluetooth. SuperDrive with double-layer support The SuperDrive built into every Power Mac G5 reads and writes to a wide variety of DVD and CD media, including double-layer (DVD+R DL) discs capable of holding up to 8.5GB of data.
Versatile CD and DVD burning The industry-standard SuperDrive writes to and reads dozens of CD and DVD formats. Writes DVD-R discs at up to 16x speed Writes DVD+R DL discs at up to 6x speed Reads DVDs at up to 16x speed Writes CD-R and CD-RW discs at up to 24x speed Reads CDs at up to 32x speed
While traditional single-layer DVD-R discs hold up to 4.7GB of data, double-layer discs have two layers of data, one of them semitransparent. The SuperDrive in the Power Mac G5 can read and write on either layer, almost doubling the storage space. This means you can author discs with over 3.5 hours of video encoded in standard MPEG-2 format on one DVD+R DL disc, compared with 2 hours of video on a standard DVD-R disc. This added capacity is increasingly important as you design DVDs with more advanced featuressuch as additional languages, multiple soundtracks, and supplementary video angleswhich require even greater disc capacity. For professional photographers, double-layer DVDs make an excellent medium for storing large numbers of highresolution photographs.
