At the third stage loader prompt (where it says something like autobooting in 9 seconds. Press Enter to boot immediately, any other key to interupt.) press any other key. You can then type "boot /kernel.GENERIC" to boot the kernel called /kernel.GENERIC. > > A pentium-II cpu uses a Pentium-PRO core, not a pentium core.
