Configuring installation hardware
UnixWare 7 automatically determines the correct hardware settings for
EISA, MCA, and PCI hardware devices needed to install the system. If you
have an ISA device, or the devices in your system have hardware conflicts
such as duplicate interrupt vectors, you need to enter the Device
Configuration Utility (DCU) by selecting Run the DCU interactively during
the installation.
You can also enter the DCU after installing your system, to add
additional hardware devices not needed by the installation. See Chapter
7, ``Adding or removing hard disks, tapes, and other devices'' for more
information.
_________________________________________________________________________
NOTE UnixWare 7 provides several other hardware configuration
managers to configure network, modem, print, audio, and video
devices after you install the system. See ``Configuring additional
hardware'' for a complete list.
_________________________________________________________________________
Navigating the DCU is comparable to navigating the installation windows,
with similar cursor movement, text entry, and help keys active.
From within the DCU, you can:
+ View hardware device configuration, to view all detected and
configured hardware on your system.
+ Modify hardware device configuration, to resolve interrupt, I/O, and
memory conflicts between devices.
+ Activate a software device driver needed by your hardware device.
+ Configure a software device driver to support the hardware.
_________________________________________________________________________
NOTE You can only make changes with the DCU once during the
installation. If you apply changes and exit the DCU, then realize
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 which supports
multiple devices.
``IPL'' The interrupt priority level, for those devices
which have priority handling capability.
``ITYPE'' The IRQ sharing type.
``BindCPU'' The CPU to which the device binds.
Additional information about these parameters is described in the
``Installation hardware checklist''.
Modifying hardware device configuration
To change a device driver parameter for a device:
1. Select Hardware Device Configuration from the DCU main menu. The
Hardware Device Configuration window appears.
2. Move the cursor to the field for the parameter you want to change.
To change an advanced parameter, first bring up the advanced window
by highlighting the desired driver and pressing <F6>.
3. Change the parameter in one of these ways:
+ Directly entering text.
+ Pressing <F2> to toggle between available choices. When the
desired choice is visible, press <Enter>.
+ Pressing <F2> to bring up a selection list and highlighting the
desired choice. When the desired choice is visible, press
<Enter>.
Continue changing values until you have removed any duplicate or
overlapping IRQ, I/O, or memory addresses.
_______________________________________________________________________
NOTE Exceptions to this rule are those devices that can share
interrupt vectors. These devices must be configured to have the
appropriate ITYPE and IPL values, or the system may not boot
correctly.

_______________________________________________________________________
NOTE Do not change entries for the keyboard. Doing so may
impair the operation of your system.
_______________________________________________________________________
4. To return to the DCU main menu, press <F10>.
5. If necessary, view and activate software device drivers and add a new
controller.
6. When you have finished making all changes with the DCU, select Apply
Changes & Exit DCU to save your changes.
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 UnixWare 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 ``Modifying 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>.
_______________________________________________________________________
NOTE 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
UnixWare 7 system, and if there are device drivers on your HBA
diskettes that you are sure will not be 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.
_______________________________________________________________________
NOTE 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. This window contains the fields for the values
found in the hardware checklist.
5. Enter the correct configuration parameters for the new controller.
After you enter these values, you can:
+ Press <F8> to cancel the new controller configuration.
+ Press <F4> to verify that correct values are entered in each field
before applying the changes.
If an error is reported, re-enter the parameter until it succeeds.
If the verification succeeds or the message Driver does not
support the verify function appears, press <Enter> to continue.
+ To apply the changes and return to the Software Device Drivers
window, press <F10>, then press <Enter>.
After you add the new controller, view the Hardware Device Configuration
window to verify that the new hardware parameters do not conflict with
the existing hardware controllers.
Configuring PC Card (PCMCIA) modems
The Network Configuration Manager configures most networking hardware
devices. However, one special type of modem -- the PC Card (PCMCIA) modem
used on some laptop computers -- is configured within the DCU.
PC Card modems are enabled by the pcic driver when the system boots up,
and are controlled by the asyc driver while in use. To configure a PC
Card modem you should first enable the pcic driver, and then create a new
asyc entry.
Enabling the pcic driver
1. Enter the Device Configuration Utility.
2. Select Software Device Drivers from the DCU main menu.
3. Select Miscellaneous from the Software Device Drivers Selection menu.
4. Enable the pcic entry if it is not already selected. If an asterisk
does not appear next to the pcic entry, move the cursor to the pcic
entry and press <Space>.
5. Press <F5> to create an instance of the pcic driver.
6. If necessary, modify the default memory range (MemStart and MemEnd).
The pcic driver requires an 8KB memory window. The D0000-D1FFF memory
range is often available on laptop computers.
7. Press <F10> to enable the pcic driver and return to the Software
Device Drivers window.
8. Press <Enter> to return to the Software Device Driver Selections
menu.
9. Select Communications Cards from the Software Device Driver
Selections menu.
10. Move the cursor to the asyc entry, and press <Space> to select it if
it is not already enabled.
11. Press <F5> to create a new instance of the asyc driver.
12. Specify this as a PC Card entry by entering 20 in the ``Unit'' field.
13. Change the default IRQ value to an available IRQ.
You can use IRQ 3 on most laptops.
14. Change the I/O address range (IOStart and IOend) to an unused I/O
address range.
On most laptops, the I/O address range 2f8-2ff is available. Set
IOStart to 2f8 and IOend to 2ff.
15. Press <F10> to create the new asyc entry and return to the "Software
Device Drivers" screen.
16. Press <Enter> to return to the Software Device Driver Selections
menu.
17. Select Return to DCU Main Menu from the Software Device Driver
Selections menu.
18. When you are finished configuring all installation devices, select
Apply Changes & Exit DCU to save your changes.
_________________________________________________________________________
NOTE For the PC Card modem to function properly, the modem must be
in the PC Card socket when the UnixWare 7 system is booted, and
should not be removed until the system is shut down.
