AtaPortWriteRegisterBufferUlong function (irb.h)

The AtaPortWriteRegisterBufferUlong routine transfers the indicated number of ULONG values from a buffer 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.
