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. When a complex i

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 processor- based Macintosh system: It's a Macintosh; it's compatible; it offers tremendous performance. Apple's PowerPC computers feature the same user interface a

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 processor- based Macintosh computers is System 7

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 Car

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. Apple RAID can also be configured for disk striping, a data storage scheme in which suc

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 Ap
