The Way of accessing ATA Drives is one, means that the way of accessing PATA HDDs is the same of SATA HDDs. also the way of accessing PATAPI ODDs is the same of SATAPI ODDs.
For that, for IDE Device Driver, it is not required to know if a drive is Parallel or Serial, but it is important to know if it is ATA or ATAPI.
===IDE Interface===
If you open your case and look at the mother board, we will see a port or two like these in the picture to the right.

The white and green ports are IDE Ports, each port of them is called channel. so there is:
- Primary IDE Channel.
- Secondary IDE Channel.
These Ports allows only Parallel Drives to be connected to, means that it supports only PATA/PATAPI Drives.
Each Port can has a PATA cable connected to, it is like this:
Image
Each PATA Cable can be connected with one master drive, or two drives [Master and Slave].
So we can have:
- Primary Master Drive.
- Primary Slave Drive.
- Secondary Master Drive.
- Secondary Slave Drive.
Each Drive May be: PATA or PATAPI.
But What about Serial IDE?
Almost many of modern motherboards have a Serial IDE which allows SATA and SATAPI Drives to be connected to.
Serial IDE Ports are 4:

Each Port is conducted with a Serial Cable:

So from the picture we can understand that only one drive can be connected to Serial IDE Port.
So each two ports make a channel, and also Serial IDE has:
- Primary Master Drive [Port1, or Port 2], also called [SATA1] in BIOS Setup Utility.
- Primary Slave Drive [Port 1 or Port 2], also called [SATA2] in BIOS Setup Utility.
- Secondary Master Drive [Port 3 or Port 4], also called [SATA3] in BIOS Setup Utility.
- Secondary Slave Drive [Port 3 or Port 4], also called [SATA4] in BIOS Setup Utility.
Please if you wanna support only the Parallel IDE, skip the part of [Detecting an IDE].
