[Cooker] Installation from second CD Drive

[Alexander Werth]

Hy I just tried to install Cooker from my second CD drive (since my
first can't read RW-CDs) and had to switch of my first CD-Rom reader
because was no way to make Cooker boot from the second scsi CD-Rom
drive. I can remember this worked before and in the rescue system it
still does.
