Work log for getting backlight on the Clevo M720R

Currently backlight control on the Clevo M720R is by hotkey only. Under windows there is a hideous program which activates the hotkeys and also displays some rather hideous bitmaps onscreen.
This series of posts will describe my attempts to disassemble the windows program. This, in turn, will enable the possibility of manually setting the brightness under linux. This will be incorporated into a hald addon or equivalent which enables nice autodimming, etc.

Today I've successfully disassembled the binary, found a way to extract the installshield application and to mine the hideous bitmap images located inside the exe. I've stilled not fully mastered the disassembly GUI. Further attempts will try to locate the actual commands given for setting and reading the brightness.
