IDE_ACCESS_RANGE structure (irb.h)

The IDE_ACCESS_RANGE structure contains the address ranges allocated for an IDE controller.

Note  The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

 

Syntax

typedef struct _IDE_ACCESS_RANGE {
  IDE_PHYSICAL_ADDRESS RangeStart;
  IDE_PHYSICAL_ADDRESS PhysicalRangeStart;
  ULONG                RangeLength;
  BOOLEAN              InMemory;
  UCHAR                Bar;
} IDE_ACCESS_RANGE, *PIDE_ACCESS_RANGE;
