It seems my local SUN-manager rememberred completely wrong. I have gotten a
lot of messages, nearly all telling me it will work, some specifying OS:es
such as 3.5. So I tried with my 4.1.1_U1 system and three disks. It works!
Just change in the config file to have targets 0,1,2,3 corresponding to
xyc0 disk xy0,xy1,xy2,xy3, and do a MAKEDEV xy* for the added drives.
(It might be a bit slow to have more than two drives though)

Thanx all !
