Configuring Plug and Play devices

Configuring Plug and Play devices

To configure ISA adapters, including sound adapters, SCSI host adapters, multiport serial boards, and others that conform to the Plug and Play ISA Specification Version 1.0A, use the SCOadmin PnP Configuration Manager:

immediately after you install the system, if you have any devices to configure
immediately after you install an ISA PnP adapter
any time you want to modify device configuration on a previously installed card

When you configure a adapter with the PnP Configuration Manager, you set the adapter's resources to match values compatible with existing UNIX^® ISA drivers.

In most cases, you should configure audio and network devices with their respective configuration managers; this ensures that the drivers and hardware are set to the same values. However, there are situations where you must use the PnP Configuration Manager for these devices:

If there are other devices on the audio adapter (for example, IDE or SCSI ports), they are not recognized by the Audio Configuration Manager and must be configured with the PnP Configuration Manager.
ISA Plug and Play network adapters are not recognized by the Network Configuration Manager. You can enable these devices using the PnP Configuration Manager, then configure them like regular ISA devices using the Network Configuration Manager.
If the Audio Configuration Manager does not recognize a new Plug and Play audio device that is compatible with an older model, you can enable the device with the PnP Configuration Manager. Then configure its audio driver by selecting the compatible device listed in the Audio Configuration Manager, using the same values you used with the PnP manager.

CAUTION: Make sure that the same values are used when configuring devices and drivers in separate steps as described here; failure to do so will cause conflicts in the Resource Manager.

Configuration consists of:

You can also use the PnP Configuration Manager to disable a device on a specified adapter.

PnP drivers are dynamically loadable modules that enable devices for use immediately after configuration is complete. However, in a few special circumstances, it may be desirable to defer hardware configuration before using the devices.

See ``Terminology and concepts'' for a glossary of terms and information on which files the manager uses and updates.
