AtaPortWriteRegisterUlong function (irb.h)
The AtaPortWriteRegisterUlong routine transfers a ULONG value to the HBA.
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.
