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-
-
Indicates whether or not the hardware controller
will (Y) or will not (N) be
configured into the kernel.
Device Name-
-
Displays the name of the device.
If a driver is assigned to an entry, the
entry will be either the device name such as ``COM Port'',
or a driver name such
as ``asyc'', the driver for the COM port.
-
If the device name is ``UNKNOWN''
on an EISA, MCA or PCI system,
this is an entry from NVRAM (Non-Volatile Random Access Memory)
indicating that the DCU cannot assign a driver name.
For example, if you have installed a network
adapter, but have not installed the corresponding software for the adapter,
it will be listed as ``UNKNOWN''.
-
If the device name is ``unused'',
this indicates that an ISA driver is disabled,
but the device parameters are retained.
IRQ-
-
Specifies the interrupt request vector (IRQ) value for the hardware
controller.
IOStart, IOend-
-
Lists the start and end addresses, in hexadecimal notation, for the
controller's I/O address range.
Memstart, MemEnd-
-
Lists the start and end addresses, in hexadecimal notation, for the
hardware controller's memory address range.
-
For an HBA controller,
these are the start and end addresses of the BIOS
for the controller.
DMA-
-
Lists the DMA channel for the controller.
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-
-
The unit number for a controller that supports multiple devices.
IPL-
-
The interrupt priority level, for those devices that have
priority handling capability.
ITYPE-
BindCPU-
-
The CPU to which the device binds.
Viewing and activating software device drivers
The following procedures allow you to view or activate the device drivers
currently installed on your system.
-
From the DCU main menu,
select Software Device Drivers.
-
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.
-
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.
-
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.
-
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.
-
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
-
From the DCU main menu,
select Software Device Drivers.
-
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.
-
Move the cursor to the desired device driver.
If the device driver is not active, activate it by pressing <Space>.
-
Press <F5> to add a new driver.
The New Hardware Configuration window is displayed.
Default values may also be displayed.
-
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.
-
To apply your configuration changes, return to the DCU
main menu and select Apply Changes & Exit DCU.
-
To end the DCU session without updating your
configuration, select Exit DCU and Cancel Changes
from the DCU main menu.
After selecting either of these options, you are returned
to where you left off in the SCO OpenServer installation.
