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

22config VGACON_SOFT_SCROLLBACK
23       bool "Enable Scrollback Buffer in System RAM"
24       depends on VGA_CONSOLE
25       default n
26       help
27         The scrollback buffer of the standard VGA console is located in
28	 the VGA RAM.  The size of this RAM is fixed and is quite small.
29	 If you require a larger scrollback buffer, this can be placed in
30	 System RAM which is dynamically allocated during initialization.
31	 Placing the scrollback buffer in System RAM will slightly slow
32	 down the console.
33
34	 If you want this feature, say 'Y' here and enter the amount of
35	 RAM to allocate for this buffer.  If unsure, say 'N'.
36
37config VGACON_SOFT_SCROLLBACK_SIZE
38       int "Scrollback Buffer Size (in KB)"

41       help
42         Enter the amount of System RAM to allocate for the scrollback
43	 buffer.  Each 64KB will give you approximately 16 80x25
44	 screenfuls of scrollback buffer

46config MDA_CONSOLE
47	depends on !M68K && !PARISC && ISA
48	tristate "MDA text console (dual-headed) (EXPERIMENTAL)"
49	---help---
50	  Say Y here if you have an old MDA or monochrome Hercules graphics
51	  adapter in your system acting as a second head ( = video card). You
52	  will then be able to use two monitors with your Linux system. Do not
53	  say Y here if your MDA card is the primary card in your system; the
54	  normal VGA driver will handle it.
55
56	  To compile this driver as a module, choose M here: the
57	  module will be called mdacon.
58
59	  If unsure, say N.

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

80          The default value is 160, which should fit a 1280x1024 monitor.

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

116       depends on FRAMEBUFFER_CONSOLE
117       help
118         Enable display rotation for the framebuffer console.  This is done
119         in software and may be significantly slower than a normally oriented
120         display.  Note that the rotation is done at the console level only
121         such that other users of the framebuffer will remain normally
122         oriented.

129          The STI console is the builtin display/keyboard on HP-PARISC
130          machines.  Say Y here to build support for it into your kernel.
131          The alternative is to use your primary serial port as a console.
132
133config FONTS
134	bool "Select compiled-in fonts"
135	depends on FRAMEBUFFER_CONSOLE || STI_CONSOLE
136	help
137	  Say Y here if you would like to use fonts other than the default
138	  your frame buffer console usually use.
139
140	  Note that the answer to this question won't directly affect the
141	  kernel: saying N will just cause the configurator to skip all
142	  the questions about foreign fonts.
143
144	  If unsure, say N (the default choices are safe).
145

151	  This is the "high resolution" font for the VGA frame buffer (the one
152	  provided by the text console 80x50 (and higher) modes).
153
154	  Note that this is a poor quality font. The VGA 8x16 font is quite a
155	  lot more readable.
156
157	  Given the resolution provided by the frame buffer device, answer N
158	  here is safe.

181	help
182	  Console font with characters just a bit smaller than the default.

215	help
216	  This is the high resolution console font for Sun machines with very
217	  big letters (like the letters used in the SPARC PROM). If the
218	  standard font is unreadable for you, say Y, otherwise say N.
