The IDE/EIDE devices

The IDE/EIDE devices
IDE(Integrated Drive Electronics) is the usual interface for hard drive. Why called IDE, IDE means that the drive has a built-in controller inside itself rather than a separate chip as a part of the motherboard chipset. Integrating the chip into the drive itself leaves manufacturers free to develop the new technology of IDE devices without worrying weather it is compatible with that chipset on certain motherboard. IDE drives are mainly compatible with the ATA (AT attachment) starndad. Which means that we can even install old drive in a new system.

EIDE(Enhanced Integrated Drive Electonics) devices were named because at the time of developing, they supported the ATA-2 standard rather than the original ATA standard. Since then, all IDE devices now fall into this category and the term EIDE is often lost and we can just refer it to IDE devices.
