252 Appendix A. Building a Custom Kernel

Boot image: /boot/vmlinuz-2.4.18-0.12-jul2001

Added linux-old

Writing boot sector.

Be sure the messages contains Writing boot sector. The * after linux means that the sec-

tion labeled linux is the default kernel that LILO will boot.

From now on, when the system boots you will see linux and linux-old as LILO boot op-

tions.

To boot the new kernel (linux) simply press [Enter], or wait for LILO to time out. If you

want to boot the old kernel (linux-old), select linux-old and press [Enter].

You can begin testing your new kernel by rebooting your computer and watching the mes-

sages to ensure your hardware is detected properly.

A.4. Building a Monolithic Kernel

To build a monolithic kernel, follow the same steps as building a modularized kernel, with

a few exceptions.

• When conﬁguring the kernel, do not compile anything as a module. In other words, only

answer Yes or No to the questions. Also, you should answer No to kmod support and

module version (CONFIG_MODVERSIONS) support.

• Omit the following steps:

make modules

make modules_install

• Edit lilo.conf to include the line append=nomodules or append the kernel line in

grub.conf with nomodules.

A.5. Additional Resources

For more information on the Linux kernel refer to these resources.

• /usr/src/linux-2.4/Documentation — Advanced documentation on the Linux kernel

and its modules. These documents are written for people interested in contributing to the

kernel source code and understanding how the kernel works.
