This manual explains how to install the hardware
and software for the Sonnet Tempo
™
Ultra ATA66
Macintosh
®
PCI Host Adapter. The Tempo Ultra
ATA66 allows you to install up to four internal
IDE hard drives (with the purchase of an addi-
tional ATA66 cable) into most PCI-based Power
Macintosh
®
computers, providing mass storage
options beyond SCSI to the larger, faster, and more
affordable Ultra ATA/66 hard drives.
This documentation assumes you have a working
knowledge of the Macintosh and its operating
conventions. If you are unfamiliar with the
Macintosh, see your computer’s documentation.
Preface
v
Support Note:
Like most technologies,
IDE devices have their own vocabulary.
The following terms may be helpful as you read
this manual.
IDE (Integrated Drive Electronics)
– A standard
electronic interface between a PCI-based system’s
memory and disk storage devices. EIDE, an
enhanced version of IDE, is commonly used in
PCI computers.
ATA (Advanced Technology Attachment)
–
The “official” name used by the ANSI (American
National Standards Institute) to describe IDE
technology.
Ultra ATA/66
– Ultra ATA/66 is the latest drive
data transfer protocol used in today’s disk storage
devices. It incorporates ATA/IDE technology with
data transfer rates up to 66MB/sec, effectively
doubling the burst data rate of the previous
transfer protocol, Ultra ATA/33. Ultra ATA/66
provides greater system throughput and data
transfer integrity.
