# Let's dive in a typical kernel booting procedure, this doesn't change too much from distro to distro (different versions of kernel and its modules generally have the same output messages) but heavily depends on the underlining hardware and its relevant drivers

# The parameters passed to this kernel:
Kernel command line: auto BOOT_IMAGE=hda10 ro root=30a
# CPU and memory initialization (here running on a Pentium 4 HT, contrary to other distros, Slackware hasn't automatically used a SMP kernel):
