Seems it works now.

a mount command takes long (about one minite for me) though I don't
know why. So don't rush.


About ibmvio, I can use a cdrom drive after bootup. However, I can't
use it from SMS (I can see a cdrom drive but I can't boot up from it).

IBM Power guys, is it possible to boot up from a virtual cdrom drive
in SMS?
