Standard VGA has what, 256K of video RAM, but there's no way to access beyond the first 64K in Chain4 mode?! That really sucks. I found (in the Ferraro book) a way to do it with the ET4000, and I'm sure it's possible with all the other major SVGA chipsets, but I want to be sure my program works on *all* VGA cards. In light of all this, I'd like to use Mode Y. Could someone please repost the SetMode code for Mode Y? Thanks in advance. > >Tomi.Engdahl@hut.fi "Don't force it; get a larger hammer" > -- +-------------------+-----------------------+--------------------------------+ | Jerry J.
