ISA Legacy Resources
Plug and Play is a configuration method that makes expanding your
server easier. Support for Plug and Play is built into the system
board of your server.
If an adapter is Plug and Play, there are no switches or jumpers that
must be set on the adapter. A Plug and Play adapter comes with
configuration specifications set in memory to provide installation
information to the server during startup. When you install or
remove Plug and Play adapters, this information is interpreted by
the BIOS, which supports Plug and Play technology. If the required
resources are available, the BIOS software automatically configures
the adapter around the resources already in use by other devices.
Most adapters designed for PCI slots are Plug and Play devices that
are auto-configuring. However, many ISA adapters are not Plug
and Play devices. These adapters 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 allocating or
reserving the system resources that the adapter will use.
Note: See “Resolving configuration conflicts” on page 57 for
information about handling resource conflicts.
Select ISA Legacy Resources to identify the available system
