Hi, Felipe,
I suggest you get a book like Running Linux by Welsh and Kaufman.
Basically, here are the steps:
Put the kernel source (I assume it's a tar.gz) into the directory
/usr/src. There will be a subdirectory there called linux. This is the
linux kernel that you're currently running. Rename this subdirectory
(e.g. mv linux linux.old) so that you have a usable kernel to fall back
on in case your new kernel turns out to be a plague. In /usr/src,
unpack the kernel source. This will create a new directory
/usr/src/linux. Now work in /usr/src/linux. In this directory, first
do:
make mrproper
Then do:
make xconfig
This is where you'll specify the features you want in the new kernel.
After you've gone through this configuration, do:
make dep
Then do:
make bzImage
This will compile the newly configured kernel. If you've selected
modular support for anything during the 'make xconfig' step, do:
make modules
The newly compiled kernel will be created as
/usr/src/linux/arch/i386/boot/bzImage. You can copy this new kernel to
a floppy or to your /boot directory and boot it with LILO. All of this
information can also be found in /usr/src/linux/README which is created
when you unpack the kernel source. OK, good luck,
Hidong
