OK, I got it.

Not having worked with mobi that much, I decided to use mobi2html.exe to create
an unpacked directory of the ebook. The "unpacked" directory had one .html file
and 843 .gif files.

Dragging&Dropping the .html file onto Calibre added the ebook as a .zip file.

I had Calibre create a .pdb file from the .zip/.html. Then I had it create a .epub
from the .pdb file. I then put both the .epub and the .pdb on the SD card I am
currently using with the JBL.

Just as you encountered, the .epub threw a "File to big" error and wouldn't load.
Oddly, the .pdb loaded and looks OK. It is odd because when the .pdb has worked
with the ebooks/manuals, that have a large number of illustrations, the conversion
of that .pdb to .epub has resulted in an .epub that also worked.

The .pdb isn't too bad and you could use that, but what looked better to me was
to just use the JBL's html reading function. I just copied the "unpacked" folder the
mobi2html.exe made onto the SD (You would probably want to rename the folder)
and it looks quite good on the JBL.

So, for mobi manual type ebook conversion for the JBL, I would now suggest just
using "mobi2html.exe" (run in the CMD "DOS Box", for XP) with a space then the
.mobi file. Then renaming the "unpacked" folder to the ebook/manual name and
copying that folder onto your FAT32 formatted SD card.

(One reason this worked so well for your manual is that it only had the one .html
file, in the unpacked folder. I have attempted to put the GIMP2 manual on the JBL
and it sorta works, but it is composed of a great many .html files, making navagation
a problem.)

Luck;
Ken
