ISA Legacy Resources
ISA Legacy Resources
Plug and Play is a configuration method that makes
expanding the server easier. Support for Plug and Play is
built into the system board of the 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 Configuration conflicts
for information about handling resource conflicts.
Select ISA Legacy Resources to identify the available system resources:
- Memory
- I/O ports
- DMA
- Interrupt
Note:
The menus do not contain resources that are used by
the system or by previously installed Plug and Play adapters.
To store the legacy resource information for an installed adapter:
- Select ISA Legacy Resources, then, use the Up
Arrow (
) or Down Arrow ( 
) key to highlight the
system resource that you want to change.
- Select a resource, then, use the Left Arrow (<) or
Right Arrow (>) key to select a configuration choice.
If you remove an ISA legacy adapter, you must redefine
the system resource as [Available].
