Integrated Drive Electronics (IDE)

The IDE controller is implemented as part of the PIIX4 chip (the PCI/ISA
bridge). It is driven from the PCI bus, and has PCI-Master capability. It
supports Enhanced IDE (EIDE) and Standard IDE. To use the Enhanced
IDE features the drives must be compliant with Enhanced IDE.
The IDE controller supports two devices (one master and one slave)
connected to a single channel. The channel is fitted with an IDE cable with
two connectors.
