HACK

Compiling the Kernel

When you have configured the kernel, you can compile it with this:

foo@bar:~$ make

foo@bar:~$ make modules_install

You no longer need to run make dep, make modules, and make clean.

Install the Kernel

The compiled kernel is placed in /usr/src/linux/arch/<platform>/boot and is

called bzImage, where <

platform> is a placeholder for the type of computer

on which you are performing the compile. For example, if you compiled

your kernel on an x86 machine, such as a Pentium, Athlon, Celeron, etc.,

you will find the kernel image in /usr/src/linux/arch/i386/boot. You must

copy this image over to /boot. You also should rename it to include the ver-

sion of the kernel in the filename so that when you have multiple kernels

you can easily tell which is which. Also, the Linux kernel image has tradi-

tionally been referred to as vmlinuz, and many users continue to call it this.

So, if you have a 2.6.5 kernel, you could copy the file with this command as

root:

foo@bar:~# cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.6.5

You should also copy the System.map file (this file has a map of the posi-

tions of symbols in the kernel and is used by programs such as

depmod) to the

/boot directory using a similar naming scheme:

foo@bar:~# cp /usr/src/linux/arch/i386/boot/System.map

/boot/System.map-2.6.5

To complete the process, just ...
