Prerequisites
- Install the Arch Linux distribution for Kernels compilation
- Install the archiso (remark: archiso requires the root permissions)
- Prepare a working directory (for example: live)
# su
# mkdir live
# cd live
# cp -vr /usr/share/archiso/configs/releng/. .
Customize the boot configuration files
- add the packages to be included into the image
# nano packages.x86_64

Boot CoreFreq
Once the CD is burned, reboot the computer selecting CDROM as the boot option.
As shown into the
Wiki, CoreFreq will be fully automatized from its compilation up to its startup.
At any time, you can exit from CoreFreq with [F4] or [CTRL] + [C]
You will be brought back to the command line where you can use the helper scripts to:
Update to the last source code (just enter
wifi to configure a wireless connection)
# corefreq_online_update.sh
Try the experimental mode (for example, the Memory Controller)
# corefreq_experimental.sh
Power off computer
