The Bus Master IDE Register set is defined by the PCI SIG. It is composed of 16 8-bit registers and is located at the I/O
address specified by Base Address Register 4. The registers can be accessed 8, 16, 24, or 32 bits at a time.
This register set is supplied to offer a higher performance lower overhead IDE disk protocol. With this protocol, the host
(PCI) transfers will be bus master cycles and the IDE device transfers will be DMA. The normal PIO protocol uses I/O
transfers on both the host and IDE interfaces. Primary and Secondary refer to the primary and secondary IDE ports. Both
register sets are identical.
