Time to compile the kernel. You can do it manually via the following commands or use the "built-it" script given below.
"cd /usr/src/kernel/linux"
"make clean"
"make dep"
"make bzImage"
and allow for the kernel to compile (~3mins on a P-II 233)
- Now, compile and install the necessary system modules:
"cd /usr/src/kernel/linux"
"make modules"
"make modules_install"
- Once the kernel has compiled, do the following command line (replacing "XYZ" with an identifing name like "2035-masq":
Slackware:
"cp /usr/src/kernel/linux/arch/i386/boot/bzImage /XYZ"
Redhat:
"cp /usr/src/kernel/linux/arch/i386/boot/bzImage /boot/XYZ"
If you would like to automate this process in the future, create this script in /usr/src/kernel and run it once you have configured your new kernel.
NOTE: You will want to create the directory /usr/src/kernel/config to store your configured kernel setups. This is a good way to find out what is and isn't enabled in a given kernel.
