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, answer No to kmod support and module version (CONFIG_MODVERSIONS) support.
Omit the following steps:
make modules make modules_install |
Append the kernel line in grub.conf with nomodules or edit lilo.conf to include the append=nomodules line.
