Figure 3-10. System Resource Usage Dialog Box To determine which card uses a particular resource shown in the System Resource Usage dialog box, select the resource in question and then click Used By Card. The Card Resource Usage dialog box appears with the information. To view the resources that a particular card is using, select the card from the list displayed in the ICU window, and then select Card Resources from the View menu or click View. The Card Resource Usage dialog box displays the resources assigned to that card. Figure 3-11 shows resources that might be assigned to a network adapter card. Figure 3-11. Card Resource Usage Dialog Box You can save the information displayed in the resource usage dialog box by clicking Print To File. The ICU then prompts you for a filename. Saving the System Configuration You can save the system configuration to nonvolatile random-access memory (NVRAM) as you configure each card's resources. To do so, select Save from the File menu and continue with your operation. Exiting From the ICU At the ICU window, select Exit from the File menu to exit the utility. If you have made any changes to the system configuration, you are asked whether you want to save the changes. If you click Yes, the ICU saves the updated system configuration information into NVRAM. If you click No, you exit the ICU without saving any of your configuration changes. If you click Cancel, nothing is saved and the utility continues to operate. Locking and Unlocking Cards The ICU includes a locking mechanism that enables you to allocate the system resources for all or for some functions of Plug and Play and PCI expansion cards. These expansion cards are dynamic, which means that they are allocated resources at system start-up. Device drivers that do not support this dynamic card configuration are referred to as static device drivers. To determine whether your expansion card has static device drivers, check the documentation that came with the drivers. If you are using a static device driver, you need to permanently associate resources with a Plug and Play expansion card, instead of relying on the default Plug and Play behavior. Otherwise, the device driver might not be able to find the card the next time the system boots. This procedure is referred to as locking a card. NOTE: The locking feature of the ICU is valid only for Plug and Play and PCI expansion cards. Locking and Unlocking All Resources To lock or unlock all the resources and configurations for a Plug and Play or PCI expansion card, perform the following steps: 1. If it is not already installed, install the Plug and Play or PCI expansion card. Then turn on the system. Complete steps 2 through 9 in "Installing an Expansion Card" in Chapter 6. 2. Start the ICU. See "Starting the ICU" found earlier in this chapter. Using the ISA Configuration Utility 3-9

System Resource Usage Dialog
Box
To determine which card uses a particular resource
shown in the System Resource Usage dialog box, select
the resource in question and then click Used By Card.
The Card Resource Usage dialog box appears with the
information.
To view the resources that a particular card is using,
select the card from the list displayed in the ICU window,
and then select Card Resources from the View menu or
click View. The Card Resource Usage dialog box dis-
plays the resources assigned to that card. Figure 3-11
shows resources that might be assigned to a network
adapter card.
Figure 3-11.
Card Resource Usage Dialog Box
You can save the information displayed in the resource
usage dialog box by clicking Print To File. The ICU then
prompts you for a filename.
S
aving the System Configuration
You can save the system configuration to nonvolatile
random-access memory (NVRAM) as you configure
each card’s resources. To do so, select Save from the File
menu and continue with your operation.
E
xiting From the ICU
At the ICU window, select Exit from the File menu to
exit the utility. If you have made any changes to the sys-
tem configuration, you are asked whether you want to
save the changes.
If you click Yes, the ICU saves the updated system con-
figuration information into NVRAM. If you click No,
you exit the ICU without saving any of your configura-
tion changes. If you click Cancel, nothing is saved and
the utility continues to operate.
L
ocking and Unlocking Cards
The ICU includes a locking mechanism that enables you
to allocate the system resources for all or for some func-
tions of Plug and Play and PCI expansion cards. These
expansion cards are
dynamic
, which means that they are
allocated resources at system start-up. Device drivers that
do not support this dynamic card configuration are
referred to as
static device drivers
.
To determine whether your expansion card has static
device drivers, check the documentation that came with
the drivers. If you are using a static device driver, you
need to permanently associate resources with a Plug and
Play expansion card, instead of relying on the default
Plug and Play behavior. Otherwise, the device driver
might not be able to find the card the next time the sys-
tem boots. This procedure is referred to as
locking
a card.
NOTE: The locking feature of the ICU is valid only for
Plug and Play and PCI expansion cards.
Locking and Unlocking All Resources
To lock or unlock all the resources and configurations for
a Plug and Play or PCI expansion card, perform the fol-
lowing steps:
1.
If it is not already installed, install the Plug and
Play or PCI expansion card. Then turn on the
system.
Complete steps 2 through 9 in “Installing an Expan-
sion Card” in Chapter 6.
2.
Start the ICU.
