Integrated Drive Electronics (IDE)
The IDE controller is implemented as part of the PIIX3 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.
Up to four IDE devices are supported: two (one master and one slave)
connected to the primary channel, and two (one master and one slave) to
the secondary channel. The primary channel is fitted with an IDE cable with
two connectors. The secondary channel is fitted with an IDE cable with one
or two connectors. If a single drive is attached to a channel, it should be in
the master position (this is the connector that is closest to the system board,
unless the markings on the cables state otherwise).
It is possible to mix a fast and a slow device, such as a hard disk drive and a
a CD-ROM, on the same channel without affecting the performance of the
fast device. The BIOS sends a command to each drive to determine,
automatically, the fastest configuration that it supports. However, in general,
the primary channel cable is recommended for hard disk drives, and the
secondary channel cable for CD-ROM drives.
