does anyone have a patch that does booting without doing a soft reset?
[ in case no-one has done it yet ... what should be done? LILO itself doesnt destroy the BIOS context, does it? If not, then is it enough to reserve the first few KBs of the memory?
then an unclean but working and present protected mode -> real mode switch and a jmp to some special address could start LILO again?
some hardware might get confused by this, but this should be just a quick hack for the often-rebooters ... unfortunatelly my BIOS does an SCSI reset even for soft reboots, which takes only a few but IMHO wasted seconds :)
or maybe if some1 is sure that only the kernel >data< structures should be updated, the kernel could go jump to start_kernel? This could be signalled to sys_reboot? Some thinking has to be done to get the kernel page tables right, but it's doable, isnt it? ]
