Configuring PCI, PC Card, EISA, and MCA adapters

The Network Configuration Manager can automatically detect PCI, PC Card (PCMCIA), EISA, and MCA network adapters that are installed in machines with those bus architectures.

For a PCI, EISA, or MCA network adapter, the Network Configuration Manager reads the configuration parameters directly from the adapter and the driver is configured automatically. You need only confirm your selection and continue with protocol stack configuration. However, you might also be prompted for ``custom'' parameters specific to your adapter if it cannot auto-configure them; see the corresponding UNRESOLVED XREF-0 configuration notes for more information about these parameters.

For a PC Card network adapter, you must enter hardware parameters such as the interrupt vector (IRQ), I/O address range, and shared memory address as you would for an ISA network adapter. See ``Driver configuration'' for more information.

NOTE: If you are installing an ISA adapter in a PCI, EISA, or MCA machine, or in a multi-bus machine with PCI, EISA, or MCA network adapters, the ISA adapter will not appear in the list of adapters found in the system. You must select the appropriate network topology (Ethernet, Token-Ring, or FDDI), or, if any autodetectable adapters are found, select Configure hardware not listed above. Then continue to configure the adapter as you would in an ISA machine. See ``Configuring ISA adapters''.

The Network Configuration Manager will not allow you to select PCI, EISA, or MCA adapters if an ISA device is using the same interrupt vector. You must change the interrupt vector in your BIOS or disable the ISA device first.

You must run the Network Configuration Manager after installing PC Card, PCI, EISA, or MCA adapters to configure them for your system. If you do so before, the drivers will not be configured automatically, and you must follow the ISA configuration procedures.
