  15           Saying Y here will allow you to use Linux in text mode through a
  16           display that complies with the generic VGA standard. Virtually
  17           everyone wants that.
  18
  19           The program SVGATextMode can be used to utilize SVGA video cards to
  20           their full potential in text mode. Download it from
  21           <ftp://ibiblio.org/pub/Linux/utils/console/>.
  22
  23           Say Y.

  29        help
  30          The scrollback buffer of the standard VGA console is located in
  31          the VGA RAM.  The size of this RAM is fixed and is quite small.
  32          If you require a larger scrollback buffer, this can be placed in
  33          System RAM which is dynamically allocated during initialization.
  34          Placing the scrollback buffer in System RAM will slightly slow
  35          down the console.
  36
  37          If you want this feature, say 'Y' here and enter the amount of
  38          RAM to allocate for this buffer.  If unsure, say 'N'.

  46          Enter the amount of System RAM to allocate for the scrollback
  47          buffer.  Each 64KB will give you approximately 16 80x25

  53         ---help---
  54           Say Y here if you have an old MDA or monochrome Hercules graphics
  55           adapter in your system acting as a second head ( = video card). You
  56           will then be able to use two monitors with your Linux system. Do not
  57           say Y here if your MDA card is the primary card in your system; the
  58           normal VGA driver will handle it.
  59
  60           To compile this driver as a module, choose M here: the
  61           module will be called mdacon.
  62
  63           If unsure, say N.

 111        ---help---
 112          If this option is selected, the framebuffer console will
 113          automatically select the primary display device (if the architecture
 114          supports this feature).  Otherwise, the framebuffer console will
 115          always select the first framebuffer driver that is loaded. The latter
 116          is the default behavior.
 117
 118          You can always override the automatic selection of the primary device
 119          by using the fbcon=map: boot option.
 120
 121          If unsure, select n.

 127          Enable display rotation for the framebuffer console.  This is done
 128          in software and may be significantly slower than a normally oriented
 129          display.  Note that the rotation is done at the console level only
 130          such that other users of the framebuffer will remain normally
 131          oriented.

 139           The STI console is the builtin display/keyboard on HP-PARISC
 140           machines.  Say Y here to build support for it into your kernel.
 141           The alternative is to use your primary serial port as a console.
