ATA100 = UDMA 100
IDE and EIDE are generally taken to mean the same things these days, simply the drive interface. IDE stands for Integrated Drive Electronics....EIDE is Enhanced Integrated Drive Interface. All current drives are EIDE.

ATA33/UDMA33/DMA33/UATA33/Ultra ATA 33 are all the same thing. It's simply a transfer mode for IDE drives that has a maximum burst rate of 33MB/s. Similarly for ATA66, where the maximum burst rate is 66MB/s.

All ATA xx standards are backwards compatible in both directions, ie an ATA100 drive will run on an ATA66 motherboard while an ATA100 motherboard will run an ATA66 drive.
