Advanced Technology Attachment Interface with Extensions
(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 PCBIOS 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"). (2000-10-07)
