PCI adapters are generally Plug and Play devices. Many ISA adapters are not Plug and Play devices. If the adapter you are installing is not a Plug and Play adapter (a legacy device), you must configure it manually. Legacy Adapters ISA adapters that are not Plug and Play devices are referred to as legacy devices. The Configuration/Setup Utility program can help you manually configure legacy adapters. The Configuration/Setup Utility program screens show the legacy resources typically required by adapters: I/O port address Memory address Interrupt request (IRQ) line Direct memory access (DMA) channel Resources not currently being used by adapters already installed in your computer are highlighted. From these screens you can select available resources for the adapter you are installing. Set the resources used by installed legacy adapters to not available. This enables the Plug and Play code to configure around legacy adapters. Then you can make the appropriate jumper or switch settings on the adapter. Using this procedure helps prevent conflicts with other adapters. Refer to the adapter documentation for information about required resources. If your computer comes with preinstalled software, you can also select these resources using the Plug and Play icon. Note The Plug and Play feature uses memory addresses ED00h to EFFFh. If you install an ISA legacy adapter or use a memory manager program, do not use the addresses within this range.
