Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

got myself a few months ago a Iriver Cover Story.
Found out that it's a Linux Based Kernel with some other stuff.
Spend some time fingering out how to get the whole firmware to be decompressed.
And to read up on ARM processors, linux kernels, U-bootloader, cramfs, etc.
Which gave me a pretty good idea whats what.
The only files not yet cracked are the *.feb
But that aside.
The 2 questions here are;
How to create a link that resides in the SD card or local flash drive to a shell terminal program that resides in the RAM memory.
Hm, first of all, the boot sequence.
When starting up, the device uses a U-bootloader raw-image and extracts the roofts.cramfs into memory. On the local flash drive you find the folders for the books, music, record, notes, etc.
Now my idea was to put a link onto the flash drive to a shell terminal in the RAM memory. So that it would be possible to start up a terminal from within the ebookreader. But there is a problem. To be able to type anything, it's neccessary to display keyboard on the touch-screen.
Also, if anyone of you here could help me with finding out how to get all the information about the ARM processor, that would be so helpfull. Don't won't to open up the device. Have tried almost every program known, but can't figure out which ARM processor is used on the device.
Could save me the trouble of uploading the firmware to test it and test it in a virtual envoirement.
