 display.sys(CMD)                19 June 1992                display.sys(CMD)


 Name

    display.sys - support code-page switching for the console

 Syntax


    device=[drive:][path]display.sys con[:]=(type[,[hwcp][,n]])

    device=[drive:][path]display.sys con[:]=(type[,[hwcp][,(n,m)]])


 Parameters


    [drive:][path]
            Specifies the location of the DISPLAY.SYS file.

    type    Specifies the display adapter in use.  Valid values include ega
            and lcd.  The ega value supports both EGA and VGA display
            adapters.  If you omit the type parameter, DISPLAY.SYS checks the
            hardware to determine which display adapter is in use.  You can
            also specify cga and mono as values for type, but they have no
            effect because code-page switching is not enabled for these de-
            vices.

    hwcp    Specifies the number of the code page that your hardware sup-
            ports.  The following list shows the code pages that MS-DOS sup-
            ports and the country or language for each:

               437  United States

               850  Multilingual (Latin I)

               852  Slavic (Latin II)

               860  Portuguese

               863  Canadian-French

               865  Nordic

    n       Specifies the number of code pages the hardware can support in
            addition to the primary code page specified for the hwcp parame-
            ter.  Valid values for n are in the range 0 through 6.  This
            value depends on your hardware.  For EGA display adapters, the
            maximum value for n is 6; for LCD display adapters, the maximum
            value for n is 1.

    m       Specifies the number of subfonts the hardware supports for each
            code page.  The default value is 2 if type is ega, and 1 if type
            is lcd.


 Notes


    Using DISPLAY.SYS with monochrome or CGA display adapters

    Because monochrome and CGA display adapters do not support code-page
    switching, using DISPLAY.SYS with either type of adapter has no effect.

    Installing a third-party console driver

    If you install both DISPLAY.SYS and a third-party console driver, such as
    VT52.SYS, the third-party device driver must be installed first.  Other-
    wise, the third-party device driver may disable DISPLAY.SYS.

 Example

    Suppose you want DISPLAY.SYS to support an EGA display adapter with a
    United States code page and the potential for two or more code pages
    without subfonts.  To do this and to specify that DISPLAY.SYS is in the
    DOS directory on drive C, add the following line to your CONFIG.SYS file:

       device=c:\dos\display.sys con:=(ega,437,2)
