IDE Drives Setup

IDE device driver controllers can support up to two separate drives. These drives have a master/slave relationship which is determined by the cabling configuration used to attach them to the controller.

PIO means Programmed Input/Output. Rather than have the BIOS issue a series of commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the controller what it wants and then let the controller and the CPU perform the complete task by themselves. This is simpler and more efficient.

The system suports five modes, numbered from 0 to 4, which primarily differ in timing. When Auto(default) is selected, the BIOS will select the best available mode. This is true for the next four setup items:

  1.  IDE Primary Master PIO
  2.  IDE Primary Slave PIO
  3.  IDE Secondary Master PIO
  4.  IDE Secondary Slave PIO
