This computer system offers an advanced expansion subsystem that can support a mixture of traditional ISA expansion cards (called legacy expansion cards), Plug and Play ISA expansion cards, and PCI expansion cards. Either the operat- ing system or the ISA Configuration Utility (ICU) provides the means to configure the various types of expansion cards and to avoid resource conflicts that might arise.

NOTES: The ICU is required only when the system runs a non-Plug-and-Play operating system (such as Microsoft ® Windows NT ® 4.0 and earlier) and includes legacy ISA expansion cards. With the Microsoft Windows® 95 operat- ing 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. Windows 95 documentation provides instructions on using the Device Manager to manage resources and resolve conflicts.

Because Dell ships only Plug and Play and PCI expansion cards on Dell Dimension systems that have a non-Plug-and-Play operating system, the ICU is not provided with systems. This utility can be downloaded from Dell’s online services.

After all legacy expansion cards have been configured by the operating system or with the ICU, the system automatically assigns any required memory space, IRQ lines, and DREQ lines to any installed Plug and Play and PCI expansion cards the next time the system is booted.
