15-STABLE install from memstick network configuration missing

Hi,

As the subject says, the only option I see is DHCP, no manual config. 
Then only option then for installation is packages but I want 
distribution sets. If I fix the network settings from a shell it is 
delete by the installer.

How can I go about installing 15-STABLE (from April 16) from 
distribution sets then?
Why does the installer want a network when the sets are aleady on the 
memstick?

Sorry if I am overlooking something but I cant get around this now.

Thanks,

Per
