Your color map is not the right length. The color map for a 16-bpp image should be 393216 bytes (196608 words).

Hmmm... I go the same message with ImageMagick's imdisplay.exe. Maybe the error message is just a bit too un-exact: the color map is there (according to the dump), maybe it's just about the unexpected length of 192kB instead of 256 byte? The values of the dump represent exactly what I have in the color map (repeated ASCII "0123456789ABCDEF").
