       vga_setchipset - force chipset


       #include <vga.h>

       void vga_setchipset(int chipset);


       Force   detection   of   a  chipset  (when  chipset  detection  fails).
       vga_setchipset(VGA) can be useful if the chipset specific stuff or  the
       SVGA detection stuff gives problems.

       However,  at first the automatic detection should work well, and if not
       a specific chipset can be forced from /etc/vga/libvga.config.

       Because of that, void vga_setchipset(int chipset) should probably never
       be  used  by  applications.  If  used nevertheless, it should be called
       directly before vga_init(3).

       As of now the following values are defined for chipset:

              This is the default and specifies autodetection.

       VGA    A plain VGA card, not that the SVGA must behave like an ordinary
              SVGA  card  then  which  will probably mean it is in an ordinary
              (25x80) textmode.
