The long and the short of it is if you have to install one of these
you have to make sure you are running one of the following prom versions
on your controller. Our service company called Xylogics before I sent
out the help mail, but the people at Xylogics didn't have any
suggestions. It wasn't until one of the responses gave me a specific
person within Xylogics to call that we got the right proms.

WHO TO CALL:
>Steve Kelley of Xylogics [(617) 272-8140 Extension 373] informed me
>that Xylogics 753-103 controllers required version 2.23 of firmware and

Unfortunatly it didn't help. Our service company said it should work,
Xylogics said it should work, the vendor who sold us the disk said it
should work (R-Squared).....but it didn't. The vendor is now supposed
to be swapping out the 2392 for two 2382's....even though they now say
they misplaced the paperwork (heavy sigh).

Responses verbatim follow:

Ken Smith forwarded me the folowing from comp.sys.sun. The very
interesting part of this was that his mail arrived before my posting to
sun-managers did.
