 Can anyone tell me why this doesn't work? 

>>>

#include <stdio.h>
#include <dpmi.h>
#include <go32.h>

void Fill_Screen(int color);
void Turn_On_VGA();

unsigned char *video_buffer = (unsigned char *)0xe00a0000L;

main()
{

  Fill_Screen(0);
  Turn_On_VGA();
  Fill_Screen(15);

  return 0;
}

void Fill_Screen(int color)
{
  int i;

  for (i=0;i<64000;i++)
   { video_buffer[i]=color; }

  return;
}

void Turn_On_VGA()
{
  __dpmi_regs r;

  r.x.ax = 0x13;
  __dpmi_int(0x10,&r);

 return;
}
