Csaba didn't implement protected mode banking with GO32 for the VESA driver. >Please, can anyone give me a clue?I really need this speedup. Don't use the VESA driver if possible.

The new one will use protected mode banking with VESA 2.0 Hartmut -- Hartmut Schirmer | E-Mail: hsc AT techfak DOT uni-kiel DOT d400 DOT de Automatisierungs- u.
