In fact, the same happens in most of the pre-made "-pae" kernels I've seen in other distributions. Just to clarify this is not only for Debian kernels. > Enabling PAE in .config before doing a kernel build does not > automatically enable SMP and the other things mentioned--they are all > separate options. Enabling "CONFIG_X86_PAE" just enables "CONFIG_X86_PAE". Yeep, that makes sense and I hope it does automatically enable another options that were not manually set... But now you mention, "NX bit" requires PAE to be "on" so I guess it will be automatically marked if you enable this. > Just making this clear so someone doesn't read this and assume "PAE" = > "SMP" in the Linux world in general. Sure, I was referring specifically to "linux-image-686-pae", I didn't think the OP was talking about compiled/home made kernels. And now you also mention this, another distributions provide a set of kernels for their users in a more flexible way: there are desktop kernels (which enable pae, nx bit and smp) and there are also plain kernels (which enable smp but keep pae and nx bit turned off).
