Thanks to every one for the help with my first problem. Finaly I could compile the new kernel, but I could not start the system with the new kernel.
I get this message: 'kernel panic: no init found. Try passing init = option to kernel' What is the value of 'option'? How I pass this value to the kernel? I am using the kernel 2.2.1 in the Debian C.D. Thanks, Camilo Alejandro Arboleda
