NAME

       vga_setmodeX - try to set Mode X-like memory organization

SYNOPSIS

       #include <vga.h>

       void vga_setmodeX(void);

DESCRIPTION

       Try to enable Mode X-like memory organization for 256 color modes using
       up to 256K of memory like 320x200x256 and 640x400x256.

       Modes   like   320x240x256   etc.   are   Mode   X-like   by   default.
       vga_modeinfo(3) lists which modes have Mode X memory layout.

       A  mode  X  like  memory  layout means that memory is organized in four
       pages (set_page(3)) and that the top most pixel 0,1,2,3 are  the  first
       pixel  in  pages  0,1,2,3. Pixels 4,5,6,7 are than the second pixels in
       pages 0,1,2,3.

       The other, packed pixel, mode will have pixel 0,1,2,3 as pixel  0,1,2,3
       in page 0 and so on. It will only use the next pages if the size of the
       first 64K page is exceeded. Most SVGA 256 color modes work this way.

       This is not guaranteed to work. Probably a new mode should  be  defined
       for planar 320x200x256.
