Hello, I am trying to write directly to the video without using bios or
dos.  But 
everytime I try this following program, I get a SIGSEGV (which i am
guessing means a segment violation?)  I attempted to re declare vidptr as
char far *vidptr but DJ does not recognize it.  So, what am I doing wrong?

int
main (void)
{
  char *vidptr = (char *) 0xB8000000;

  *vidptr = 'a';                      /* Write a to screen. */
  *(vidptr + 1) = (char) 1;      /* In blue. */

  return 0;
}
