How to install modules after finished the installation

["Alex Kwan" <kwanalex@hkstar.com>]

Hi!

After I completed the installation of the Base System
of Hamm, I found that I need some modules which
have not selected from Step "Install Operation Kernel 
and the Device Driver" of Installation Program, How do
I install these modules? In dont' want to re-install the 
Base System.


Thanks & Regards,
Alex
