I will refer to a separate thread I created concerning this.

in short:
The chm reader on the 903 does not handle chapters well.
It only counts the pages until the first "chapter" it encounters.
You need to do tricky things to read chapters.
It should just append all chapterts together as one big text, but retaining the chapters as index links (bookmarks)
PLease fix it for the september update release.
chm is a common ebook format.
thx
