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