Using the ISA Configuration Utility 4-1& + $ 3 7 ( 5 8VLQJWKH,6$&RQILJXUDWLRQ8WLOLW\The ISA Configuration Utility (ICU) is used by the system to track what expansioncards are installed and what resources are used. With this information, the systemautomatically configures Plug and Play expansion cards and Peripheral ComponentInterconnect (PCI) expansion cards and can tell you how to configure non-Plug andPlay Industry-Standard Architecture (ISA) expansion cards manually by setting jump-ers or switches. Plug and Play and PCI expansion cards do not contain jumpers andswitches; they are configured only through software in the basic input/output system(BIOS).&$87,21 7KH ,&8 LV LQWHQGHG RQO\ IRU FRQILJXULQJ QRQ3OXJ DQG 3OD\ ,6$H[SDQVLRQ FDUGV ,W VKRXOG QRW EH XVHG IRU DVVLJQLQJ UHVRXUFHV WR 3OXJ DQG3OD\ H[SDQVLRQ FDUGV DQG 3&, H[SDQVLRQ FDUGV 7KHVH FDUGV VKRXOG EH FRQILJXUHG DXWRPDWLFDOO\ E\ WKH %,26NOTE: The Windows NT operating system does not provide full Plug and Play sup-port. Therefore, some Plug and Play cards (such as modem, sound, and networkcards) may not work with Windows NT. If your system is running a Dell-installedWindows NT operating system and you want to use Plug and Play cards, Dellrecommends that you use the card manufacturer’s configuration utility to set the cardto legacy mode, enter the card’s resources through the manufacturer’s utility, andthen use the ICU to add the Plug and Play card to your system configuration. On sys-tems with a Dell-installed Windows NT operating system, the ICU is installed on thehard-disk drive as a diskette image. Use the Program Diskette Maker (located in theDell Accessories program folder) to make an ICU diskette from this diskette image.The remainder of this chapter describes the various features of, and the various waysto use, the ICU.
