Removing hardware controllers
The UnixWare system automatically detects when some controllers
(for example, supported EISA, MCA, or PCI hardware) are installed on
the system.
If such controllers are removed from
the system, the device driver
parameter settings for the controller are automatically removed
from the system resource database.
However, if the UnixWare system cannot detect
whether a controller is installed on your system,
the controller's device driver parameter settings are not automatically
removed from the system resource database when you remove the hardware.
ISA controller settings must be removed manually using the
Device Configuration Utility (DCU).
General information about the DCU is available in
``Using the Device Configuration Utility (DCU)''.
You can use this procedure to remove ISA hardware components from your system.
-
From the DCU main menu, select Hardware Device Configuration.
-
From the "Hardware Device Configuration" screen,
move the cursor to the row containing the device
driver settings for the controller.
-
If you plan to reinstall the ISA controller or peripheral later,
you may want to temporarily disable access to the controller.
This keeps the device driver settings for the controller in the
system resource database.
Change the value in the Device Name field to
unused
.
NOTE:
To reactivate the controller, change the device name
from unused
back to the name of the device driver.
-
If you do not intend to reinstall the controller,
remove the controller's device driver settings from the system
resource database.
If the value in the first field on the DCU
screen is Y, change it to N.
-
Exit the "Hardware Device Configuration" screen.
-
Select Apply Changes & Exit DCU.
-
If you are removing a controller from your system, decide whether
the device driver parameter settings for the controller should
be removed from the system resource database.
-
Select Apply Changes & Exit DCU.
-
Shutdown the system.
-
When prompted, turn off the system power switch.
-
If the hardware peripheral(s) have power switches, turn them off.
-
Remove the hardware controller(s) or peripheral(s).
-
Turn on the power for all devices that are connected to your system.
-
Rebuild or reboot the system.
