14	help
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'.

40config VGACON_SOFT_SCROLLBACK_SIZE

45       help
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

50config MDA_CONSOLE
51	depends on !M68K && !PARISC && ISA
52	tristate "MDA text console (dual-headed)"
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.

70          Say Y here if you want the console on the Newport aka XL graphics
71          card of your Indy.  Most people say Y here.

83          The default value is 160, which should fit a 1280x1024 monitor.
84          Select 80 if you use a 640x480 resolution by default.
85

91          The default value is 64, which should fit a 1280x1024 monitor.

105       depends on FRAMEBUFFER_CONSOLE
106       default 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.

119config FRAMEBUFFER_CONSOLE_ROTATION

121       depends on FRAMEBUFFER_CONSOLE
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.

134        help
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.
