Cybook PID

Nate the great · 01-30-2009, 07:05 PM

Is there a file on the Cybook where the PID is recorded? If not, is there a serial number? Thanks.

Not sure if I am helping. MY PID number on my Cybook Gen 3

is in this location:

Yes, but that won't do us any good unless calibre can find it. I want calibre to (eventually) keep track of device PIDs.

gotcha.

There clearly is a way to obtain it, because the Mobi Desktop Reader program does so.

Open the system.dat file in folder system with a texteditor. There should be somekindof Serialnumber, if there are blocks, use another texteditor, maybe openoffice.

mmm, nothing seems obvious in any of the .dat files on mine ..

It couldn't be something that easy, or it would be easy to change the ereaders' PID

GeoffC · 02-27-2009, 12:05 PM

?probably something in the firmware - or a hidden file ...

It's more likely some kind of "hardware-ID" like the MAC-address, I dont think there is a file lying around anywhere on the reader.

But, nonetheless, there clearly is a way for the PID to be retrieved through software. The CyBook's "About" screen can retrieve it, and the MobiPocket Desktop reader can even read it remotely via a USB connection.

Perhaps someone could examine the code for the Mobi Desktop Reader and see how it's retrieving the PID.

That would involve some amount of reverse engineering and thus isn't quite as easy as it sounds.

I'm certainly not suggesting that it would be an easy task! But it should be "do-able" if anyone is keen enough to want to find out how it's done.

Well, maybe one of the resident code gurus is up to the task, but I'm way out of my league with something like that.
What I did was take a look at the .dat-files in the system directory, which seemed to be the only ones available besides the font cache. The file config.dat seems to contain some configuration data (surprise, surprise!), including the last opened book (By the way, the SD card is mounted in /mnt/etc2 although it's formatted in FAT.). The second file, icudt36l.dat, contains an awful lot of data including what seems to be a listing of files on what I assume to be the internal file system, but a search for either the word PID or my Cybooks PID turned up empty. I'd assume there's a second partition in internal memory which isn't readily accessible using a windows system, perhaps because it would be formatted using ext2 (or ext3, doesn't matter for the purpose of speculation, I think). Maybe somebody using a unixoid OS could take a look, as I sadly lack the time for a more in-depth search.

Yes, there is an internal partition which contains the firmware, and which is not externally visible.
