You may want to try removing *all* passive terminators on *all* drives.
Can't promise anything from this, though.
You may also want to try movig the viper to ID 6 (I know, weird) or
arranging the devices:
1542c->Viper->Q->Q
(I know: also weird).

Is this thig repostable? Sound like we ought to have one living on agate.

If 386BSD's SCSI driver can discriminate between the 1542c and 1542b, then
there a way to tell them apart and they're not compatable.
I like to look at it that way.
