Hello,

many modern notebooks have a BIOS which is capable to save the
(used) memory, processor registers etc. to hard disk (mostly to empty
space of a FAT partition). Unfortunately there are notebooks (even new
ones) which don't have this feature. That I own such a thing is the main
reason (despite that someone may not have a FAT partition, may have a
desktop system etc., ...) for asking why it shouldn't be possible
to realize this within the Linux kernel and loader (LILO).
I am not an expert on the Linux boot process, but shouldn't it be possible
to save (after disabling interrupts etc.) the used memory (in a first
attempt maybe even the whole memory) and other status information onto
disk (unused swap space, ...)? LILO would have to recognize such a
situation and continue from there.

Any comments?

Regards,
Lutz
