Ok, I found some info in the linuxrc file
But I have other questions..
For example:

********** linuxrc ************
mount -t proc none /proc
mount -t devpts none /dev/pts
********** linuxrc ************

Those line. How can mount those file? When those directory are created?

Next
********** linuxrc ************
# Give control to the init process.
echo "${CRE}${BLUE}Starting init process.${NORMAL}"
rm -f /linuxrc
exit 0
********** linuxrc ************
Where we start init?
Thanks a lot
