Plug and Play Technology
Plug and Play Technology
Plug and Play
is an ISA technology designed to make expanding the server
easier. Plug and Play adapter support is built into the
system board in the server. If the operating system
supports Plug and Play technology, the server will
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:
- I/O port address
- Memory address
- IRQ line
- 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].
Note:
- Refer to the documentation that comes with the
adapter for information about required system
resources. Then, make the appropriate jumper
or switch settings on the adapter.
- If you have a resource conflict, set the resources
that are used by the ISA legacy adapter to [ISA
Legacy]. This will manually configure the ISA
legacy adapter to that specific server resource.
Once Plug and Play detects that a resource is
not available, it will skip that resource, and
reconfigure to other available system resources.
