I'm trying to get fast vbe 2.0 (with linear frame buffer) graphics
at 640x480x256 yet am having some difficulties.

I'm drawing the images to a video  buffer (video[640*480]) and then
try to display with

for(int i=0; i < 307200; i+=4)
{
        temp = ((unsigned long)(video[i])) << 24\
        + ((unsigned long) (video[i+1])) << 16\
        + ((unsigned long) (video[i+2])) << 8\
        + ((unsigned long) (video[i+3]));  
        
        _farnspokel(i, temp);
    
}

where temp is a unsigned long and I've already done a
_farsetsel(my_video_ds) but I'm not having much success.

I know univbe can do about 60 fps on my system at 640x480x356 but
it uses multiple pages.  Does anyone know how to use multiple pages or
why codellet doesn't work as I want it to?

Thanks in advance,
