Guidelines The modules in these directories are provided as built for each kernel. They are here in case you need to construct a bootable system by hand. Unlike the installable package, these are uncompressed when placed in /lib/modules. You may fix this if you wish. Personally, I'd reccomend finding a way to install a package so they can be easily and painlessly upgraded. The modules for sun4cdm.s were built without SMP support. Those for sun4dm_smp.s were built with SMP support. The Ultra kernel, sun4u.s, always has SMP built-in. --Jason
