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.
