(ATA-2, Enhanced Integrated Drive
Electronics, EIDE) A proposed (May 1996 or earlier?)
standard from
X3T10 (document 948D rev 3) which extends
the
Advanced Technology Attachment interface while
maintaining compatibility with current
IBM PC BIOS
designs.
ATA-2 provides for faster data rates, 32-bit transactions and
(in some drives)
DMA. Optional support for power saving
modes and removable devices is also in the standard.
ATA-2 was developed by
Western Digital as "Enhanced
Integrated Drive Electronics" (EIDE) around 1994.
Marketroids call it "Fast ATA" or "Fast ATA-2".
ATA-2 was followed by
ATA-3 and
ATA-4 ("Ultra DMA").
