General firmware question
This is not specific to the iLiad. Is there an easy way to determine the filesystem, compression, etc. of a firmware image for a different ebook reader?
I just ordered a Jetbook and I understand that it runs Linux. I have some general Linux skills, but am not up on embedded firmware issues. Since the Jetbook comes with only two sans-serif fonts, I want to see about adding more fonts and rebuilding the firmware image.

In the case of the iliad, the firmware is a compressed image of the system partition of the device.
If you want to investigate the firmware you have, a good starting point is using the "file" command, as in:
$ file firmwarefile
If the firmware is a simple compressed file, you can uncompress it and do a "file" over the results.
Bear in mind that in embedded linux is not uncommon to have the "firmware" be a encrypted zip file, so only the upgrade program can use it, not the user.
Hope that helps.
