Basics Power Macintosh System Overview - 1 Power Macintosh System Overview PowerPC microprocessors are a family of processors built on reduced instruction-set computing (RISC) technology. RISC processors streamline the internal workings of computers. Whereas traditional (complex instruction-set computing, or CISC) processors contain a wide variety of instructions to handle many different tasks, RISC processors contain only those instructions that are used most often.
Basics Power Macintosh System Overview - 2 Previously, RISC technology had been used only in high-end workstations and commercial database servers. With the introduction of Macintosh PowerPC computers, Apple succeeded in bringing RISC technology to personal computing. Key Points Three key points to remember about a PowerPC processorbased Macintosh system: It's a Macintosh; it's compatible; it offers tremendous performance.
Basics Power Macintosh System Overview - 3 Compatibility is not limited just to applications. INITs, CDEVs, drivers, and other Macintosh utility software also work on PowerPC processor-based Macintosh systems. So do AppleTalk devices (such as printers), SCSI devices (such as hard drives and scanners), ADB devices (such as mice, trackballs, and keyboards), and other Macintosh cards and peripherals. The primary operating system for PowerPC processorbased Macintosh computers is System 7.
Basics Power Macintosh System Overview - 4 of the fastest 68040- and 80486-based personal computers, the real promise of PowerPC technology is that it enables Apple and other developers to deliver new software capabilities on Macintosh systems that were previously available only on high-end workstations. Troubleshooting Tips When troubleshooting Power Macintosh systems, keep in mind the following: 1 2 If a Power Macintosh system does not power up, you should first attempt to reset the logic board.
Basics Power Macintosh System Overview - 5 3 4 provided in the Symptom Charts section of the Troubleshooting chapter under the “System” topic heading. If a Power Macintosh system has bad RAM SIMMs installed, you will not hear death chimes. Instead, a dialog box will appear alerting you to the fact that a bad RAM SIMM has been detected. Additional troubleshooting information is provided in the Symptom Charts section of the Troubleshooting chapter under the “System” topic heading.
Basics Power Macintosh System Overview - 6 5 The Power Macintosh AV systems use the same logic board as the non-AV versions. The only difference is that the AV versions have the Power Macintosh AV Card installed in the PDS slot. The Power Macintosh 7100/66 and 8100/80 systems must have a video card installed in the PDS slot. The Power Macintosh 7100/66 system uses the Power Macintosh 2 MB Video Card and the Power Macintosh 8100/80 system uses the Power Macintosh 4 MB Video Card.

Caution: It is important to note that the Power Macintosh 8100/100 and 8100/110 Series logic boards have a thermoelectrical cooling device that attaches directly to the microprocessor’s heatsink. You can identify this cooling device by the black and red wires that run to the right of the heatsink and plug into the logic board via a keyed connector.

Basics Apple RAID Software - 17 Apple RAID Software Apple RAID (Redundant Array of Independent Disks) software protects data from loss during a disk failure and enhances the speed of data storage and retrieval. It is available for all Power Macintosh Workgroup servers. Data protection is achieved through disk mirroring, a data storage scheme in which identical data is stored on two different disks.
Basics Apple RAID Software - 18 • If you wish to use your server's startup disk for Apple RAID, do not install the Apple RAID program on your startup disk until you have initialized and set up new volumes on that disk. Before you initialize the startup disk, back up all valuable data. • You must reinitialize all disks on which you will use Apple RAID volumes. Initializing with Apple RAID removes all data, so be sure to back up your disks first. • Apple HD SC Setup does not recognize Apple RAID volumes.
Basics Apple RAID Software - 19 back up your system files now. Back them up in such a way that you can restore your system files separately from the nonsystem files on your disk. You will later restore your system files using the backup copy rather than the System Installer on the RAID CD, so that you preserve your system customizations.
