I think that you probably want WIDE set to OFF, and SE set to ON.  Assuming
that those machines still have SCSI at all, that should be what it takes to
get it working.

As Mike said, a drive that is just LVD will only work on LVD busses.  Most
LVD drives also have a jumper to enable/disable LVD, which puts the drive in
SE (single ended), which is the "normal" SCSI from older machines.
