automatically configure itself when you install an ISA Plug
and Play device.
Note
PCI adapters are also often referred to as plug and
play because they configure automatically.
Plug and Play adapters:
Plug and Play adapters are
easier to install and set up because they are
auto-configuring. This means that there are no jumpers or
switches to set.
A Plug and Play adapter comes with built-in identification
and configuration specifications (set in memory on the
adapter) that provide installation information to the server
during startup. This information is read by the input/output
(I/O) bus and interpreted by the server BIOS. The BIOS
routines automatically configure the adapter around the
resources already in use by other devices.
Legacy adapters:
If an adapter that you install is not
Plug and Play compatible, the Configuration/Setup utility
program can help you to manually configure the adapter.
Adapters that are not Plug and Play compatible are known
as
legacy devices.
Configuration/Setup Utility program:
Within the
Configuration/Setup utility program, the Plug and Play
screen displays server resources that are typically required
by adapters:
Ÿ
I/O port address
Ÿ
Memory address
Ÿ
IRQ line
Ÿ
DMA channel
From the Configuration/Setup utility program screens, you
can select available resources for the adapter that you are
installing. Resources that are not currently being used by
adapters that are already installed in the server are listed
as [ISA Legacy]. The system resources that are in use by
other devices are listed as [Not Applicable].
