VAXStation 4000/90 Hard drive options

...
   Yeah...I just
recently got an IBM drive that has absolutely refused
 to work on any narrow SCSI bus I've tried it on.  I had to set the "force
single ended" and "disable wide" jumpers on
 an IBM disk to get it going on the narrow channel of my AlphaServer
 2100... 
This drive has a "FORCE SE MODE" jumper, but no "disable wide"
jumper.
There is a "DIS F/W NEG" jumper which turns out to expand to "disable
fast/wide negotiation".  It also has three other disable jumpers:

DIS TI SY (disable TI sync negotiation)
DIS PAR (disable parity)
DIS UN A (disable unit attention)

I've tried with all four disable jumpers _and_ the FORCE SE MODE
jumper, and it _still_ doesn't work with my SS20. :-(

I am annoyed.
