- Name:
- AtaSoftReset

- Purpose:
- This function is used to implement the Soft Reset on the specified
- device. But, the ATA Soft Reset mechanism is so strong a reset method
- that it will force resetting on both devices connected to the
- same cable.
- It is called by IdeBlkIoReset(), a interface function of Block
- I/O protocol.
- This function can also be used by the ATAPI device to perform reset when
- ATAPI Reset command is failed.
-
- Parameters:
- IDE_BLK_IO_DEV IN *IdeDev
- pointer pointing to IDE_BLK_IO_DEV data structure, used
- to record all the information of the IDE device.
- Returns:
- EFI_SUCCESS
- Soft reset completes successfully.
