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

  20. default n
  21. help
  22. The scrollback buffer of the standard VGA console is located in
  23. the VGA RAM. The size of this RAM is fixed and is quite small.
  24. If you require a larger scrollback buffer, this can be placed in
  25. System RAM which is dynamically allocated during initialization.
  26. Placing the scrollback buffer in System RAM will slightly slow
  27. down the console.
  28. If you want this feature, say 'Y' here and enter the amount of
  29. RAM to allocate for this buffer. If unsure, say 'N'.

  41. ---help---
  42. This enables support for text mode selection on kernel startup. If
  43. you want to take advantage of some high-resolution text mode your
  44. card's BIOS offers, but the traditional Linux utilities like
  45. SVGATextMode don't, you can say Y here and set the mode using the
  46. "vga=" option from your boot loader (lilo or loadlin) or set
  47. "vga=ask" which brings up a video mode menu on kernel startup. (Try
  48. "man bootparam" or see the documentation of your boot loader about
  49. how to pass options to the kernel.)
  50. Read the file <file:Documentation/svga.txt> for more information
  51. about the Video mode selection support. If unsure, say N.

  56. Say Y here if you have an old MDA or monochrome Hercules graphics
  57. adapter in your system acting as a second head ( = video card). You
  58. will then be able to use two monitors with your Linux system. Do not
  59. say Y here if your MDA card is the primary card in your system; the
  60. normal VGA driver will handle it.
  61. To compile this driver as a module, choose M here: the
  62. module will be called mdacon.
  63. If unsure, say N.

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

  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.
  123. config STI_CONSOLE

  127. help
  128. The STI console is the builtin display/keyboard on HP-PARISC
  129. machines. Say Y here to build support for it into your kernel.
  130. The alternative is to use your primary serial port as a console.
  131. config FONTS

  134. help
  135. Say Y here if you would like to use fonts other than the default
  136. your frame buffer console usually use.
  137. Note that the answer to this question won't directly affect the
  138. kernel: saying N will just cause the configurator to skip all
  139. the questions about foreign fonts.
  140. If unsure, say N (the default choices are safe).

  146. This is the "high resolution" font for the VGA frame buffer (the one
  147. provided by the text console 80x50 (and higher) modes).
  148. Note that this is a poor quality font. The VGA 8x16 font is quite a
  149. lot more readable.
  150. Given the resolution provided by the frame buffer device, answer N
  151. here is safe.
