Commit cc208a15 authored by Christian Costa's avatar Christian Costa Committed by Alexandre Julliard

The SVGA block code was not accessible (AH and AL inverted). Fixed.

Removed duplicate VESA Get SuperVGA INFORMATION function. Fix and finish its implementation. Add 2 functions to managed structures in the BiosSys segment.
