Pro zprovoznění s OS CentOS 5.2 bylo nutné překompilovat kernel, protože incializace končila kernel panicem:

Kompilace probíhala na jiném stroji, neb na ALIXu na ni nebylo dostatek výkonu CPU ani místa na CompactFlash kartě. Stáhnuly a nainstalovaly se zdrojové kódy kernelu pro CentOS. Poté se v souboru "kernel-2.6.18-i686.config" provedla následující úprava:

CONFIG_X86_POWERNOW_K8=m
CONFIG_X86_POWERNOW_K8=n

Také se upravil soubor "kernel-2.6.spec":

#% define build
%define build .ALIX

a pak již následovala kompilace:

rpmbuild -bb --target=i686 --with baseonly kernel-2.6.spec
