The ATAPI driver provides support for
Extended IDE (EIDE) CD-ROM drives by
representing the drive as a SCSI device to the operating system.
In order to present a consistent interface, the following restrictions apply:
A maximum of two IDE controllers can be present on any system.
No more than two IDE devices might be present on any one
IDE controller.
If there are two devices on the controller, one must be configured as
a ``Master'' device and the other as a ``Slave'' device.
If only one IDE controller is present,
it must be configured as the ``Primary'' controller.
If there are two controllers, one must be configured as ``Primary'' and
the other as ``Secondary''.
NOTE:
The procedure you need to apply to install and configure EIDE- or
IDE-interface hardware
(controllers, disk drives, ATAPI CD-ROM,
and ATAPI tape drives)
for your system is described in the
documentation provided by your hardware supplier.
Any information provided by your hardware supplier
might invalidate the information here.
