A very familiar problem. It means that your bios configures your ICH
chipset for legacy (or whatever name it has) mode, which means it will
respond to the old-fashioned IDE ports and IRQs. This also means you
cannot drive it in AHCI mode :-( unless there is an option in your BIOS
to switch between legacy and ahci mode, but afaik no single laptop has
this option. So you're on your own here :-( (just like me, btw).
