ATAPI and IDE, difference?

[Guest]

What is the difference between new ATAPI thing and old IDE? They are the same but why they are callled differently?

I'm not sure on the specifics, but I think that ATAPI was a standard produced in an attempt to standarize IDE devices. Hopefully someone can give you further information.

IDE is how hard drives, CD-ROMs, etc. interface with your computer. ATAPI is a tunneling protocol (works inside of IDE) that enables Windows to control CD-ROMs and tape drives. ATAPI is NOT used for hard drives. Both are used for CD-ROMs and tape drives.


ATAPI
(AT Attachment Packet Interface) The specification for IDE tape drives and CD-ROMs. See IDE.


EIDE
(Enhanced IDE) An extension to the IDE interface that supports the ATA-2 and ATAPI standards. ATA-2 (Fast ATA) provides faster transfer rates (see IDE for details) and allows for multiple channels, each connecting two devices. ATAPI supports non-hard disk devices such as CD-ROMs and tape drives. It also specifies a new BIOS for supporting hard disks greater than 504MB. Since mid-1994, PCs have shipped with EIDE interfaces, and most motherboards provide a primary and secondary channel for a total of four devices. In practice, the terms EIDE and IDE are synonymous. See IDE and LBA.

Also known as Large Block Addressing. This is the method by which the bios understands just how whacked FAT really is. See also "Why Nes98 is so unstable".[/bold]
