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 85 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:
Ÿ
Memory resources
Ÿ
I/O port resources
Ÿ
DMA resources
Ÿ
Interrupt resources
See “ISA Legacy Resources” on page 39 for instructions to use the
Configuration/Setup Utility Program to configure legacy adapters to work
in your computer.
