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'.

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

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.

103config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
104 bool "Map the console to the primary display device"
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.
118
119config FRAMEBUFFER_CONSOLE_ROTATION
120 bool "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.
128

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.
