Legacy Adapters Adapters that are not Plug and Play compatible are known as legacy devices. If you install a legacy adapter, you must manually configure it by setting switches on the adapter and by allocating system 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: Memory resources I/O port resources DMA resources Interrupt resources From the appropriate screens, you can select available resources for the adapter you are installing. Resources not being used by ISA legacy adapters are listed as [Available]. You must set the resources used by the newly installed ISA legacy adapter to [ISA Resource]; this reserves the resources for the legacy adapter and prevents the BIOS from using these resources for the system or other Plug and Play adapters. Just as you change system resources when you install an ISA legacy adapter, you must also change resources when you remove an ISA legacy adapter. If you remove a legacy adapter, change the resources it formerly used to [Available]. This allows the Plug and Play software to automatically use these resources for future configurations, or they can be used later when other legacy adapters are installed. Note: Refer to the documentation that comes with the adapter for information on required system resources. For information on configuring ISA legacy adapters, see "Configuring an ISA Legacy Adapter" on page 80 or refer to Using Your Personal Computer. For information on error messages from resource conflicts, see Using Your Personal Computer. 30 Installing Options in Your Personal Computer

Legacy Adapters
Adapters that are not Plug and Play compatible are known as
legacy devices
.
If you
install a legacy adapter, you must manually configure it by setting switches on the
adapter and by allocating system 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:
±
Memory resources
±
I/O port resources
±
DMA resources
±
Interrupt resources
From the appropriate screens, you can select available resources for the adapter you
are installing.
Resources not being used by ISA legacy adapters are listed as
[
Available
].
You must set the resources used by the newly installed ISA legacy
adapter to [
ISA Resource]
; this reserves the resources for the legacy adapter and
prevents the BIOS from using these resources for the system or other Plug and Play
adapters.
Just as you change system resources when you install an ISA legacy adapter, you
must also change resources when you remove an ISA legacy adapter.
If you
remove a legacy adapter, change the resources it formerly used to [
Available
].
This
allows the Plug and Play software to automatically use these resources for future
configurations, or they can be used later when other legacy adapters are installed.
Note:
Refer to the documentation that comes with the adapter for information on
required system resources.
For information on configuring ISA legacy adapters, see “Configuring an ISA
Legacy Adapter” on page
80 or refer to
Using Your Personal Computer
.
For
information on error messages from resource conflicts, see
Using Your Personal
Computer
