FR> And yes, x86 cpus *can* be reset without loosing the mem, that's what 286 DOS FR> extenders did to return to real mode because intel thought protected mode was FR> so nice nobody would ever want to get out of it =))) But that's not really what is needed here... what is the point of resetting only the CPU, apart from getting out of protected mode, if you don't cleanly reload anly operating system components? The whole discussion, BTW, loses a lot of its point as soon as there is a suspend-to-disk option, either with ACPI or without it. Philipp
