13.4 DMA Data Transfer Commands
These commands are:
Read DMA
Read DMA Ext
Write DMA
Write DMA Ext
Initiation of the DMA transfer commands is identical to the Read Sector or Write Sector commands
except that the host initializes the slave-DMA channel prior to issuing the command.
The DMA protocol allows high performance multi-tasking operating systems to eliminate processor
except that the host initializes the slave-DMA channel prior to issuing the command.
The DMA protocol allows high performance multi-tasking operating systems to eliminate processor
overhead associated with PIO transfers.

13.5 First-parity DMA Commands
These commands are:
Read FPDMA Queued
Write FPDMA Queued
Execution of this class of commands includes command queuing and the transfer of one or more
blocks of data between the device and the host. The protocol is described in the section 4.2 “Native
