I did some more tests and:
1) Using only the old slave/hard drive works - it's detected by
sysinstall. (The new drive is disconected.)
2) I replaced the FreeBSD boot manager with the standard boot manager,
but still the FreeBSD boot manager kicked in unless I disconnected
the old slave. This seems to indicate that the old slave also has
a FreeBSD boot manager installed...
The next obvious step (to me) is to remove the FreeBSD boot manager
from the old slave. I guess I can do it with sysinstall, but how?
The data on the disk can not be lost... Is there other things I should
