1)Can read the appendix of the book Understanding Linux Kernel 3rd Ed as chap said erlier. However if you just want to print a message while booting, just follow your intuition in the / directory.You just need to add a line with your text somewhere ;-). 2)Can start here , though you will need more http://www.faqs.org/docs/kernel/x1206.html 3) While not a guide on (the more complex) USB, you can play with some LEDs connected to parrarel, a pretty common tutorial on the net, http://www.freesoftwaremagazine.com/articles/drivers_linux You can find the same on Linux Device Drivers chapter 10 (google the free ebook) All in all, while I dont consider myself anything close to being kernel hacker or experienced kernel coder, while you are walking through that path, you should make yourself familiar with the OS internals (maybe reading the whole book the chap said earlier?) or look for material like that on the net.

I am good at C programming. I have learnt to write "hello world" type of kernel modules using printk() statements. I know nothing else about kernel programming. I want to become a kernel hacker. I am a newbie at the moment. To begin with, I have 3 goals. 1. To understand how the Linux kernel first boots. To make sure that I have got hold of the correct code, I want to insert a "hello world" message in the booting code such that my "hello world" message is displayed along with other important messages while booting. 2. To understand how the kernel reads input from the keyboard and prints output on the screen. To test my understanding, I would like to modify the kernel to log all key strokes in a file. 3. How we can send out signals or electric pulses to a particular port, say USB port. I would like to test my understanding by writing a kernel module or something that sends out voltage from the USB port or anything else that would light up an LED or 3 V bulb. If some question of mine doesn't make sense, please tell me so and guide me what I should study and work on to accomplish my first 3 goals in this field. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [EMAIL PROTECTED] Please read the FAQ at http://kernelnewbies.org/FAQ -- Claudio Eduardo Marques Gomes Estudante de Engenharia da Computação Diretor de Tecnologia do CAECOM Projeto DCC-INDT em Baixo Consumo de Energia em Sistemas Embarcados Universidade Federal do Amazonas (UFAM) Tell: 92 3088-3845 Cel: 92 9183-8100
