And if you reboot there is time delay and the point is why doing it, if you can just smash another kernel image in ram memory and drive. I mean, this does not make sense in production environment use, it is for debugging. Anyway, the simplest first try is to get somehow at grub command line and load kernel image in ram and hope this works :) If not, then write small program is the only solution. The only concern is can you burn your laptop with assembly instructions ?? :) thanks, Dragoslav Zaric [Programmer; M. Sc Astrophysics]
