These items are for the shadow and cacheable option of
ROM code on the expansion cards (including VGA). The
shadow means to copy ROM code into faster DRAM and
hence improves the execution performance of these
ROM code. Cache them will further improve the
performance but there are some cards have
incompatible problem if cache its ROM code. You need
to know the specific addresses of the ROM code, for
example, VGA BIOS occupies segment C000 and C400,
so that the default of C000 and C400 are Cached. If you
do not know this information, enable all the ROM
shadow settings. This ensures shadowing of any
present ROMs and reduces the available memory.
Note: The F000 and E000 segments are
always shadowed because BIOS code
occupies these area.
