A simple clear screen routine in Borland C...

void Clear( int color )
{
   unsigned  i = 64000;
   char far* VidMem = (char far*) 0xa0000000L;

   while( i-- )
      *VidMem++ = color;
}

A simple putpixel routine...

void PutPixel( int x, int y, int color )
{
   char far* VidMem = (char far*) 0xa0000000L;

   *(VidMem + x + y * 320) = color;
}

There... simple, eh?
