==Support in operating systems==

When operating systems initialize their codepage switching logic, they need to know but have no means to determine the previously active hardware code page.<ref name="Paul_2001_CPSwitchFD"/><ref name="Caldera_1998_USER"/><ref name="Paul_1997_NWDOSTIP"/><ref name="Paul_2001_NWDOSTIP"/>

Under [[DOS]] and [[Windows 9x]] this is accomplished by specifying the hardware codepage as a parameter to the [[device driver]]s [[DISPLAY.SYS]] and [[PRINTER.SYS]] (hwcp) in [[CONFIG.SYS]]:

: <tt>[[DEVICE (CONFIG.SYS directive)|DEVICE]]=...\DISPLAY.SYS CON=(type,hwcp,n|(n,m))</tt><ref name="Paul_2001_CPSwitchFD"/><ref name="Caldera_1998_USER"/><ref name="Paul_1997_NWDOSTIP"/><ref name="Paul_2001_NWDOSTIP"/>
