  That's what I hear too but It's never made in difference in anything
  in my experience.

  You noticed I said that I hadn't had TOO much trouble. I actually have
  2 of the 2930u cards. Home and at work. At home all I have connected
  is a 4gb barracuda, exabyte 8500 tape drive and a Yamaha CRW8424 cdrw.
  At work a have the same but 3 additional 4gb barracuda's. The exabyte
  tape and Yamaha CDRW have been added recently. That's when my problem
  started. Almost every time I reboot the machine right after the
  sequencer
  code is loaded I get messages about a reset because of a time-out from
  a test-unit-ready. It usually points to scsi device id=0. Sometimes it
  says somthing about trying harder and sometimes it'll succeed in what
  ever
  it's trying to do. But more often than not it will appear to be in an
  endless loop and I have to power down and power back up. That USUALLY
  will let it boot on up.
 
   At home after recently adding the same Yamaha CDRW I find the same
  thing
  happening to me just not as frequent.
 
   At work if I remove the exabyte tape and Yamaha I never have this
  problem. Once I'm able to get the machine up all works great.
 
   What kind of devices do you have connected? Do ya have a SCSI CD/RW?
 
  I've been meaning to gather up all the info relating to my problem
  and post it to the list but haven't as yet. Your the first to hear
  about it. There is no doubt in my mind that my problem is a  driver
  problem. Monday, from work I'll right down all the messages I get
  and post my problem to the list.

By the way, When I try to mail to you directly my mail gets returned
as spam???????????
 
  regards
