Models without any PCI boards, such as the Matrox Millennium Graphics controller or the Ethernet Network controller, are supplied with a PCI terminator. This should be plugged into any PCI slot, and removed if ever a PCI accessory board is subsequently installed. 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 (one for the desktop models, two for the minitower models).
