I changed the name of this thread in hopes of getting some more help. When opening the files in a hex editor, I see large sections of stuff filled with FF's or 00's. Hopefully someone here more knowledgeable than I can make a bit of sense of this. I saw on one site that the files are compressed with RLE compression but need tools from Insyde to recompress? I am really confused by all of this. I know I did see RSDT mentioned as well as TOSINV (which I know is one of the SLIC names but I don't see any slic reference in the file).
