It is a copy of Basic Input/ Output Operating System (BIOS) routines from read-only memory in a special area of random access memory (RAM) so that they can be accessed more rapidly. Access in shadow RAM is normally in the 60-100 nanosecond range while ROM access is in the 125-250 ns range. In some operating systems like DOS, certain BIOS routines are not only employed during boot or start up of the system, however also during normal operation, especially to drive video display terminal. In Windows & OS/2, though, these routines are not employed and the use of shadow RAM is not essential. In some systems, user can turn the use of shadow RAM off or on.
