[Debootloaders-yaboot] Bug#641852: yaboot modification needed for successful boot with Power5 - device= change needed, plus yaboot 1.3.16

[Michael Felt]

Hi,

Last march I went through a difficult (for me) process to get a 
successful boot when using netinst to install debian on my Power5 (p505) 
system.

The key to success is:
use expert64 install choice
after additional package selection and installation choose "Go Back" 
rather than Continue
at menu choose "execute a shell"
then
# chroot /target
# cd /tmp
# wget 
http://ftp.us.debian.org/debian/pool/main/y/yaboot/yaboot_1.3.16-4_powerpc.deb 
<http://ftp.us.debian.org/debian/pool/main/y/yaboot/yaboot_1.3.16-4_powerpc.deb>
# dpkg -i yaboot_1.3.16-4_powerpc.deb
# vi /etc/yaboot.conf
and change:

## device=/vdevice/v-scsi at 30000002/@1
device=/vdevice/v-scsi at 30000002/@8100000000000000:2

# ybin
# exit
# exit
  and complete installation.
* reboot partition - stopping in SMS menu
* change bootlist (as installation does not change it to harddisk)
* continue boot process
* Debian on Power should be running!

Hope this helps! (Note: changes to yaboot.conf also attempted with 
yaboot 1.3.13 and did not work)

System Info:
POWER5 Firmware: SF240_418
VIOS level: 2.2.2.0
Using IVM (no HMC)
