 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.

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

122        help
123          Enable display rotation for the framebuffer console.  This is done
124          in software and may be significantly slower than a normally oriented
125          display.  Note that the rotation is done at the console level only
126          such that other users of the framebuffer will remain normally
127          oriented.

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