Yeah, you just take the IDE cable from the motherboard to the optical drive.

Literally speaking, IDE and EIDE are obsolete protocols, but most people use the terms IDE, EIDE, ATA, and ATAPI interchangeably. The current standard is ATA-7 with an Ultra-DMA transfer rate of 133 MB/s.

Do not get ATA confused with SATA. SATA, or Serial ATA, is a completely different protocol with a completely different set of power and data connections for the drives. It is quite a bit faster and much more efficient than regular ATA. When comparing ATA and SATA, ATA is usually referred to as PATA, or Parallel ATA. As far as I know, no motherboard features SATA exclusively, so if a motherboard has SATA, it should still have PATA, as well.

So to get to the point, when someone says EIDE, IDE, ATA, ATAPI, or PATA, it's the same thing - ATA. All current motherboards should have the latest version.

Just as a side note, ATA-8 is in the works. Perhaps it will compare to SATA speeds? Even if it did, it would still be very inefficient. Not to mention the big plug (compared to the SATA connection).
