Devices on the PCI Bus
with two connectors. For desktop models, the primary channel cable is
fitted with two connectors, and the secondary channel cable is fitted with
one connector.
With EIDE, it is possible to have a fast device, such as a hard disk drive, and
a slow device, such as a CD-ROM drive, on the same channel without
affecting the performance of the fast device. However, in general, the
primary channel cable is recommended for hard disk drives, and the
secondary channel cable for CD-ROM drives. Indeed, if a CD-ROM is placed
on the same channel as a hard disk drive, problems could be experienced
activating the 32-bit access drivers.
Other PCI Accessory Devices
PCI expansion cards (accessory boards) are used for high-speed peripheral
accessories. Up to three PCI cards can be installed in minitower models, and
up to two PCI cards can be installed in desktop models.
