I was able to shuffle the bytes into the order that Linux expects like this: def shuffle(b): r = [] for i in range(0, len(b), 6): r.extend(b[i+2:i+6]) r.extend([0, 0]) r.extend(b[i:i+2]) return r The code then turned out to be slightly different. The processor (GFP) appears to implement a custom architecture, but amazingly it's documented in chapter 5 of <http://download.adaptec.com/pdfs/user_guides/aic6915_pg.pdf>. In theory, someone could write an assembler and disassembler for the GFP and then create a new preferred form for modification. > | "(c)2001 Adaptec, Inc.
