Plug and Play Adapters Plug and Play is a configuration method that makes expanding your computer easier. Support for Plug and Play is built into the system board of your computer. A Plug and Play adapter has no switches or jumpers that must be set. A Plug and Play adapter comes with configuration specifications set in memory. These specifications provide installation information to the computer during startup. When you install or remove Plug and Play adapters, this information is interpreted by the basic input/output system (BIOS), which supports Plug and Play technology. If the required resources are available, the BIOS software automatically configures the adapter using resources not already used by other devices. Adapters designed for PCI slots are Plug and Play devices. Most ISA adapters are not Plug and Play and are referred to as legacy adapters. See "Legacy Adapters." Note: See Chapter 8, "Troubleshooting" on page 83 for information on error messages resulting from resource conflicts. Legacy Adapters Adapters that are not Plug and Play are known as legacy adapters. If you install a legacy adapter, you must manually configure it by setting switches or jumpers on the adapter and by reserving its resources using the Configuration/Setup Utility Program. In the Configuration/Setup Utility Program, the ISA Legacy Resources screen shows the computer resources that are typically required by adapters: Memory resources I/O port resources DMA resources Interrupt resources See "ISA Legacy Resources" on page 37 for instructions to use the Configuration/Setup Utility Program to configure legacy adapters to work in your computer. What to do next: To work with another option, go to the appropriate section. To complete the installation, go to "Completing the Installation" on page 77. 68 PC 300GL User Guide
