Solaris 10 - non-interactive flash install

I have a jumpstart server setup and it's functional. I can do a standalone install no problem. I have created rules, sysidcfg, and profile files for both the standalone install and flash install.

But when I try to do flash install, everything is non-interaticve up to this point (it asks me to create a root password but in my rules file I have specified a finish script to create the root password non-interactively):
-------------------------------
.....
.....
.....
checking ufs filesystems
/dev/rdsk/c0t0d0s7: is logging.
Creating new rsa public/private host key pair
Creating new dsa public/private host key pair
----------------------------------------------

Then it asks me to specify a language:

----------
Please specify the media from which you will install Solaris 10 Languages for
SPARC Platforms.
-----------

How can I get rid of those two interactive screens?

the simplest way is to specify both in sysidcfg.
