Plug and Play software such as Configuration Managers
and the ISA Configuration Utility (ICU).

ISA Shared Memory Size
The ISA Shared Memory Size field is used to set a block
of system memory which will not be shadowed.
(Shadowing is a technique which copies a block of
memory from an address in the expansion board’s ROM
to the same address in the system memory to allow faster
access to the code and achieve higher performance.)
If “Disabled,” all upper memory is shadowed and ISA
Shared Memory Base Address field is not displayed.
This field provides the following choices.
When a value other than “Disabled” is selected, a block
is unshadowed and the ISA Shared Memory Base
Address field will appear.
