[comp.sys.amiga.hardware] 2091 & multiple drives--the real scoop?

dylan@cs.washington.edu (Dylan McNamee) (10/31/90)

I have recently added a second drive to my 2091 system.  I carefully
followed all the advice given here about making sure the drives
were marked as not supporting reselection, to work around a bug
that would be fixed "in a free ROM upgrade."

I managed to crash my machine by dowloading to disk as I was
compiling on the other drive.  It appears the reselection workaround
didn't work.

So I called my dealer, who informed me that the 2091 roms have been
around for quite a while, but that it isn't being treated as a 
warranty repair, and the cost would be around $60.

Hmmm.  Has ANYONE out there recieved this ROM upgrade?  Did it work
wonders for disk performance?  (Reselection is KEY to decent HD
performance with multiple drives)  How much did it cost?

Does anyone from CBM care to comment?  (My machine is March vintage
2500/30...)  How could they get away with charging for this thing
while it's under warranty?

thanks, and sorry for whining...

I too am interested in the real scoop. From the answeres I get there is NO
problem of multiple SCSI drives hooked to a 2091 controller. But I keep seeing
users saying they can't get things to work propperly. I am one of these
people. When you hear exactly conflicting answeres you don't know what to
think. Just want to know the truth here!

	I can't see how they could get away with it... Your machine is
under warranty. If there's a set or updated ROMs available, you should
be able to get them for free. but  then, I don't work for either a
dealer or Commodore... :-)

Ok, here's the situation.  The latest ROMs are the 6.1 revisions.
These ROMs support two drives.  If you don't have the 6.1 ROMs,
then go to your dealer and demand to see the April-May 90 tech
notes.  Find the second article about the ROMs. It tells about
a free in-warranty upgrade because there is a problem with the
Western Digital Controller chip which doesn't work with two drives
without the upgraded ROM.

Can we get a new controller chip?

Commodore has really disappointed me this time.  I've been waiting nearly
a year for this "fix".

Greg, this ROM revision has been around since at least last July.  I had
my system in the shop for some other service, and had them replace the
ROMs at the same time.  Don't know why you don't have them yet.  I was
charged some $20 for them, though.

Also, I'm just a tad unsure that 6.1 is the latest revision as stated by
Mr. Adams.  A while back I was talking about this with someone in email
who said it wasn't, and that the latest wasn't available when I had the
upgrade done.  Sorry, I can't remember anything else.  I also have only
one drive connected at this time, so I haven't encountered any of the
problems. :-\

I apologize if this has been a known fix.  However, my dealer knew nothing
about ROM upgrades between July and last month.  I checked several others
in the area and they didn't know anything about it during that time either.

I also called Commodore last month to asked them about a "known fix" for
the bug.  The nice lady stated that a Tech Note had JUST gone out about it
and dealers should be getting the new ROMs Real Soon Now.  That was in
September.

So, count yourself lucky, you've got a hell of a dealer!

My dealer STILL has not seen ANY new ROMS for the A2091 since I bought the
damn machine a year ago.

Why does the controller chip say "Proto" on my A2091?  Is it common industry
practice to use prototype parts in production machines?  I'm not being
snotty, I really don't know if that's common.  Seeing "Proto" on the
Western Digital chip certainly IS disconcerting.  It makes me wonder if the
ROMS contain some horrendous hack around a problem with pre-production hardware.
Anyone know if this is the case and, if so, if it impacts performance?

Again, I apologize if this is old news, I've been monitoring the newsgroup
all along and not seen much discussion of whole A2091 affair.  I hope
I've not missed something.
