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.
