81FFh special full-memory access mode
</PRE>
<p><b>Notes:</b>
The special mode 81FFh preserves the contents of the video memory and
gives access to all of the memory; VESA recommends that the special
mode be a packed-pixel mode. For VBE 2.0+, it is required that the
VBE implement the mode, but not place it in the list of available
modes (mode information for this mode can be queried directly,
however)..
As of VBE 2.0, VESA will no longer define video mode numbers
