You can run 32bit programs on many 64bit kernels, but a 32bit kernel only runs 32bit code, since the code can't use 64bit features if the kernel doesn't know about them and know how to context switch without loosing the 64bit extensions. As far as I know this is true of at least x86, hppa (not sure 64bit is supported in linux since I never worked with one), mips and sparc. -- Len Sorensen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
