I suspect that many of them are drivers for particular devices. Is there any resource or documentation available? Thanks. P.S. Here are the first few: ahc_eisa ahc_isa ahc_pci alias_cuseeme See e.g. ahc(4). However, what I do is: makeoptions MODULES_OVERRIDE="geom/geom_part acl_nfs4" in the kernel config file, or include whichever modules you use. This way you only build/install what you actually need. On some boxes I don't build any modules at all: makeoptions MODULES_OVERRIDE="" Also, many drivers I build into the kernel, because I use them all the time, so the extra flexibility of modules is not required there.
