Hi, did you mean "modules"?
Since modules are part of the kernel, it is most recommended to leave them installed (assuming you want to delte them completely). You can uninstall modules from memory by typing:
Then, you can edit the file /etc/rc.d/rc.modules and comment out the modules that you do not want loaded (just put a # before the line). This way, the module will not be reloaded after restarting the system.
