To shadow ROM means to copy its contents into the computer's
system or random-access memory (RAM). This is beneficial for two
reasons: ROM has (relatively) long access times and the processor
can access RAM faster than ROM; second, the contents of RAM
can be cached for even greater performance. All of the computer's
system BIOS ROM is shadowed.
The ROM Shadowing option allows you to shadow video BIOS
and up to three 32 Kbytes areas of expansion card ROM (that is,
ROM fitted on ISA or PCI expansion cards) addressed between
C8000h and DFFFFh.
See the chapter entitled, 'Expansion' for more information about
addressing expansion card ROM.
