+additional software is about 42MB on top of that.

+# aptitude install kernel-image-2.6-s390x

 <h2>Final Note</h2>

 I hope this HOWTO helped you get started with a mainframe of your own. I
 tried to be as accurate and specific with the details where I thought it was
 necessary - the S/390 specific parts. If you have any suggestions, or
 comments (content, spelling, etc.) feel free to contact me via email:
