1.2.13 Hard Disk Drive

IDE HDD
The ICH6 IDE controller features one set of interface signals that can be enabled, tri-stated or driven low. The IDE
interfaces of the ICH6 can support several types of data transfers:
Programmed I/O (PIO): processor is in control of the data transfer
8237 style DMA: DMA protocol that resembles the DMA on the ISA bus, although it does not use the 8237 in
the ICH6. This protocol off loads the processor from moving data. This allows higher transfer rate of up to
16MB/s
