Installing and configuring hardware

Configuring installation hardware

SCO OpenServer automatically determines the correct hardware settings for PCI hardware devices needed to install the system. If the devices in your system have hardware conflicts such as duplicate interrupt vectors, you need to run the Device Configuration Utility (DCU) by pressing <F8> from the ``Load the required HBA drivers'' installation screen.

You can also run the DCU after installing your system, to add additional hardware devices not needed by the installation. As root, enter mkdev dcu at a shell prompt.

See ``Using the Device Configuration Utility (DCU)'' in the online documentation and the dcu(ADM) manual page for more information.

SCO OpenServer provides several other hardware configuration managers to configure network, modem, print, audio, and video devices after you install the system. See ``After the installation''.

Navigating the DCU is comparable to navigating the installation windows, with similar cursor movement, text entry, and help keys active.

The rest of this section describes:


NOTE: During an installation, you can only make changes with the DCU once. If you apply changes and exit the DCU, and then realize that you need to make more changes, you must re-start the installation.

Viewing hardware device configuration

To view the currently detected hardware on your system, select Hardware Device Configuration from the DCU main menu. The Hardware Device Configuration window appears. This window displays hardware parameters for each device configured on your system. If a value is not needed, a dash appears in its place.

The fields shown are:


Configuration Status

Device Name

IRQ

IOStart, IOend

Memstart, MemEnd

DMA

To view additional information about any of the entries, use the arrow keys to highlight the desired controller and press <F6>. When you do, you see configuration information for the following advanced parameters:


Unit

IPL

ITYPE

BindCPU

Viewing and activating software device drivers

The following procedures allow you to view or activate the device drivers currently installed on your system.

  1. From the DCU main menu, select Software Device Drivers.

  2. Select a device driver category. If you are unsure which category the desired device driver is in, select All Software Device Drivers. The Software Device Drivers window for the selected class of device drivers is displayed. The window contains three fields:

    Active/Inactive
    If an asterisk (*) appears in this field, the driver is available for use assuming the hardware it supports is installed and enabled. If the field is empty, the device driver is inactive and supports no devices.

    Driver
    Lists the device driver name.

    Names of Supported Devices
    Lists the hardware controllers the device driver supports (if available).

    Many device drivers support multiple controllers. The Software Device Drivers window lists the controllers supported by each device driver. If a device driver is inactive, the system cannot access any of the controllers that the device driver supports.

  3. To view a specific device driver, move the cursor to it and press <F6>. Information about the driver appears. For a description of the fields, see ``Viewing hardware device configuration''.

    Press <Enter> to return to the Software Device Drivers window.

  4. To activate a device driver, move the cursor to the device driver's status field and press <Space>.

    If you want to add a new controller, the device driver that supports this controller must be active.

  5. If you are an experienced administrator who is installing the system, and if there are HBA device drivers that you are sure are not needed on your system, you can instruct the installation software not to install these device drivers. To do so, remove the asterisk next to each of these device drivers.

  6. To apply the changes and return to the Software Device Drivers window, press <F10>, then press <Enter>.

Adding a new controller for a device driver

  1. From the DCU main menu, select Software Device Drivers.

  2. Select a device driver category. If you are unsure which category the desired device driver is in, select All Software Device Drivers. The Software Device Drivers window for the selected class of device drivers is displayed.

  3. Move the cursor to the desired device driver.

    If the device driver is not active, activate it by pressing <Space>.

  4. Press <F5> to add a new driver.

    The New Hardware Configuration window is displayed. Default values may also be displayed.

  5. Enter the correct configuration parameters for the new controller. After you enter these values, you can:

    After you add the new controller, view the Hardware Device Configuration window (see ``Viewing hardware device configuration'') to verify that the new hardware parameters do not conflict with the existing hardware controllers.

Returning to the installation

Configuration changes made in the DCU do not take effect until they are applied.

After selecting either of these options, you are returned to where you left off in the SCO OpenServer installation.
