Assuming you get to the BIOS, this is true. But with kexec, there is
work being done on accomplishing a true "warm boot", where you reboot
without ever touching the BIOS. As I understand it, the kernel simply
shuts down everything, loads the new kernel (if applicable), and
launches it
But since Terry mentioned that he was in the BIOS settings editor he was
already outside the linux kernel, so this is obviously not relevant, so
sorry for mentioning it :)
