installing s390x on hercules

[KURASHIKI Satoru <lurdan@gmail.com>]

hi,

I've tried to install debian wheezy s390x on hercules, but
I can't boot it.

Please tell me correct procedure to do so.

My steps are:
1. Basically, I follow the instruction of this page:
   http://www.josefsipek.net/docs/s390-linux/hercules-s390.html

   * I use daily d-i image (http://d-i.debian.org/daily-images/s390x/daily/generic/)
     and choose expert mode to get shell prompt.

2. installer fails to find proper kernel. so I've dropped to shell prompt, and do:
   # /target/usr/sbin/chroot /target /bin/bash
   # apt-get install linux-image-s390x
   # exit

3. continue without bootloader (There is not another option...)

4. after rebooting, I command "ipl 120" and get error:
> HHCCP048I 0120:CCW=03000000 00000001=>00060000 0000000F 03000000 00000001 ................
> HHCCP075I 0120:Stat=0E00 Count=0001
> HHCCP076I 0120:Sense=80000000 00000002 00000000 00000000 00000000 00000000
> HHCCP077I 0120:Sense=CMDREJ
> HHCCP029E z/Arch mode IPL failed: CSW status=0E00
>            Sense=80000000 00000002 00000000 00000000 00000000 00000000 00000080 00000000

I guess that I have to edit s390.cnf to specify device correctly, but how?
(after passing this, I will be blocked by bootloader issue...)
