Detailed Description

Hard disk Control based Device Control Register.

Struct used to read from Device Control Register of Control port. Used to reset the bus or enable/disable interrupts. There is an additional IO port that changes the behavior of each ATA bus, called the Device Control Register. Each ATA bus has its own Control Register. All other bits are reserved and should always be clear. In general, you will want to leave HOB, SRST, and nIEN cleared. Set each Device Control Register to 0 once, during boot.
