The solution to my problem won't help you, unfortunately. I use a QIC-36
controller, not a SCSI. However, if anyone else out there has the same
problem I did, it turned out to be yet another case of RTFM(anualS)
*carefully*. Kambiz Reissedonna at Dell Computers UNIX Support pointed out
tactfully that I hadn't paid attention to both manuals. The Everex QIC-36
comes configured using IRQ 3. ISC UNIX 3.3 wants to use IRQ 5. So, all I
needed to do was open the case and change the molex plug setting this
morning. My Wangtek 150M drive seems to work ok now. Of course, it still
doesn't really stream when using tar. But it seems to work pretty well when
using dd or ddd ....todd
