  config VGA_CONSOLE

  	default y
  	help
  	  Saying Y here will allow you to use Linux in text mode through a
  	  display that complies with the generic VGA standard. Virtually
  	  everyone wants that.
  
  	  The program SVGATextMode can be used to utilize SVGA video cards to
  	  their full potential in text mode. Download it from
  	  <ftp://ibiblio.org/pub/Linux/utils/console/>.
  
  	  Say Y.
  
  config VGACON_SOFT_SCROLLBACK
         bool "Enable Scrollback Buffer in System RAM"
         depends on VGA_CONSOLE
         default n
         help
           The scrollback buffer of the standard VGA console is located in
  	 the VGA RAM.  The size of this RAM is fixed and is quite small.
  	 If you require a larger scrollback buffer, this can be placed in
  	 System RAM which is dynamically allocated during initialization.
  	 Placing the scrollback buffer in System RAM will slightly slow
  	 down the console.
  
  	 If you want this feature, say 'Y' here and enter the amount of
  	 RAM to allocate for this buffer.  If unsure, say 'N'.
  
  config VGACON_SOFT_SCROLLBACK_SIZE
         int "Scrollback Buffer Size (in KB)"
         depends on VGACON_SOFT_SCROLLBACK
         range 1 1024
         default "64"
         help
           Enter the amount of System RAM to allocate for the scrollback
  	 buffer.  Each 64KB will give you approximately 16 80x25
  	 screenfuls of scrollback buffer
  
  config MDA_CONSOLE
  	depends on !M68K && !PARISC && ISA
  	tristate "MDA text console (dual-headed)"
  	---help---
  	  Say Y here if you have an old MDA or monochrome Hercules graphics
  	  adapter in your system acting as a second head ( = video card). You
  	  will then be able to use two monitors with your Linux system. Do not
  	  say Y here if your MDA card is the primary card in your system; the
  	  normal VGA driver will handle it.
  
  	  To compile this driver as a module, choose M here: the
  	  module will be called mdacon.
  
  	  If unsure, say N.
  
  config SGI_NEWPORT_CONSOLE
          tristate "SGI Newport Console support"
          depends on SGI_IP22 
          select FONT_SUPPORT
          help
            Say Y here if you want the console on the Newport aka XL graphics
            card of your Indy.  Most people say Y here.
  
  config DUMMY_CONSOLE

          default "160"
          help
            The default value is 160, which should fit a 1280x1024 monitor.
            Select 80 if you use a 640x480 resolution by default.
  
  config DUMMY_CONSOLE_ROWS
          int "Initial number of console screen rows"
          depends on PARISC && DUMMY_CONSOLE
          default "64"
          help
            The default value is 64, which should fit a 1280x1024 monitor.
            Select 25 if you use a 640x480 resolution by default.
  
  config FRAMEBUFFER_CONSOLE

  	depends on FB && !UML
  	select VT_HW_CONSOLE_BINDING

  	  Low-level framebuffer-based console driver.
  
  config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
         bool "Map the console to the primary display device"
         depends on FRAMEBUFFER_CONSOLE
         default n
         ---help---
           If this option is selected, the framebuffer console will
           automatically select the primary display device (if the architecture
  	 supports this feature).  Otherwise, the framebuffer console will
           always select the first framebuffer driver that is loaded. The latter
           is the default behavior.
  
  	 You can always override the automatic selection of the primary device
  	 by using the fbcon=map: boot option.
  
  	 If unsure, select n.
  
  config FRAMEBUFFER_CONSOLE_ROTATION
         bool "Framebuffer Console Rotation"
         depends on FRAMEBUFFER_CONSOLE
         help
           Enable display rotation for the framebuffer console.  This is done
           in software and may be significantly slower than a normally oriented
           display.  Note that the rotation is done at the console level only
           such that other users of the framebuffer will remain normally
           oriented.
  
  config STI_CONSOLE
          bool "STI text console"
          depends on PARISC
          select FONT_SUPPORT
          default y
          help
            The STI console is the builtin display/keyboard on HP-PARISC
            machines.  Say Y here to build support for it into your kernel.
            The alternative is to use your primary serial port as a console.
