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.

25config VGACON_SOFT_SCROLLBACK
26       bool "Enable Scrollback Buffer in System RAM"
27       depends on VGA_CONSOLE
28       default n
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
48	 screenfuls of scrollback buffer

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.

109       depends on FRAMEBUFFER_CONSOLE
110       default 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.

126       help
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.

138        help
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.
