The problem is most PC's have no battery backup or memory control register that shows the batteries had failed. VAX hardware would init memory if the register showed that memory was just powered up. It the memory was ok and still valid it would pull a restart vector off the stack and run... The issue is hardware. I've seen Unix systems from three vendors (Including AT&T and BSD based stuff) do this. (Didn't Ultrix do this... SVR0 from AT&T used to be able to handle this -- I know their later boxes did).
