Overview
The ISA Configuration Utility (ICU) is used by the system to track what expansion cards are installed and what resources are used.
With this information, the system automatically configures Plug and Play expansion cards and Peripheral Component Interconnect
(PCI) expansion cards and can tell you how to configure non-Plug and Play Industry-Standard Architecture (ISA) expansion cards
manually by setting jumpers or switches. Plug and Play and PCI expansion cards do not contain jumpers and switches; they are
configured only through software.
CAUTION: The ICU is intended only for configuring non-Plug and Play ISA expansion cards. It should not be used
for assigning resources to Plug and Play expansion cards and PCI expansion cards. These cards should be
configured automatically by the basic input/output system (BIOS).
NOTES: The Microsoft Windows NT operating system does not provide full Plug and Play support. Therefore, some
Plug and Play cards (such as modem, sound, and network cards) may not work with Windows NT. If your system is
running a Dell-installed Windows NT operating system and you want to use Plug and Play expansion cards, Dell
recommends that you use the card manufacturer's configuration utility to set the card to legacy mode, enter the card's
resources through the manufacturer's utility, and then use the ICU to add the Plug and Play expansion card to your
system configuration. On systems with a Dell-installed Windows NT operating system, the ICU is installed on the hard-
disk drive as a diskette image. Use the Dell Program Diskette Maker (in the Dell Accessories folder) to make an ICU
diskette from this diskette image.
If you are using the Microsoft Windows 95 operating system, the functions provided by the ICU are handled by the
Device Manager, which can be accessed by double-clicking the System icon in the Control Panel. See your Windows 95
documentation for instructions on using the Device Manager to manage resources and resolve conflicts.
The remainder of this chapter describes the various features of, and the various ways to use, the ICU.
