can't find certain yast modules

hello, I work now with suse 11.1 with kde4; and there is in yast > hardware, no module “cd-rom drives”, no module “disk controller” and no module “ide-dma mode”.

When I installed suse, I did a normal install; added the development packages and did not remove packages.
In Yast I have the sources: openSUSE 11.1-Update; ISO (dvd); NVIDIA; Packman; openSUSE-11.1-Non-Oss and openSUSE-11.1-Oss.

In Yast > software manager > search, I searched for yast; for module; for cd-rom; etc… (also with description ); but I didn’t find these modules and/or packages.

Where can I find these modules? Maybe this is a really stupid question, but i can’t find them. :shame:
