2095.0. "MSKB Q150305: DEC FDDI Adapters Fail to Respond to Broadcasts" by CSC32::BINGHAM (Scott Bingham �� Windows NT / BackOffice Team, USCSC) Fri Jul 26 1996 19:14

        Hello folks,

        Below is an article that Microsoft has recently added to their
Knowledge Base, as MSKB Q150305.  Can anybody respond with the proper
firmware to resolve this problem, if indeed it is on the level?

        Thanks,

MSKB Q150305

DEC FDDI Adapters Fail to Respond to Broadcasts

PRODUCT NAME: Microsoft Windows NT

SOURCE: Microsoft Corporation


-------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Workstation version 3.51
 - Microsoft Windows NT Server version 3.51
-------------------------------------------------------------------------

SYMPTOMS
========

When you use the Windows NT 3.51 DEFEA.SYS or DEFPA.SYS for the DEC EISA or
PCI FDDI network adapters, the driver fails to respond to broadcast
packets.

CAUSE
=====

This problem occurs due to firmware problems on the network adapter.
Certain chipsets of the adapter causes any registered broadcast addresses
to clear during the adapter reset. DEFPA.SYS and DEFEA.SYS drivers reset
the adapter for a variety of conditions reported by the adapter during
normal use.

RESOLUTION
==========

To correct this problem, apply the fix mentioned below.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51. A
supported fix is now available, but has not been fully regression-tested
and should be applied only to systems experiencing this specific problem.
Unless you are severely impacted by this specific problem, Microsoft
recommends that you wait for the next Service Pack that contains this fix.
Contact Microsoft Product Support Services for more information.

    Scott,
    
    Please, please tell me who is responsible for writing these reports?
    I have yet to see ONE of these reports that are DEFEA or DEFPA related
    be 100% accurate.
    
    Since you seem to be "in the know", please find out whether there's a
    chance that I can be part of the review board for future DEFEA or DEFPA
    related problem reports.

    Incorrect.  This is not, and never was a firmware problem.  Both the
    DEFEA.SYS and DEFPA.SYS drivers (v1.57) had a bug in which the
    BROADCAST address (FF-FF-FF-FF-FF-FF) filter would be disabled during
    software reset.  When issuing a SW reset of the adapter, all of the
    filters are disabled and any modified FDDI settings are returned to
    their default values.  The driver is responsible for maintaining the
    filter settings, multicast addresses, node address override, etc. and
    wasn't doing it properly for the Broadcast Address Filter.

    The latest DEFEA.SYS and DEFPA.SYS driver (v1.82) that ships in the
    v2.7 DEFEA and DEFPA SW kits fixes this problem.  I'm sure that
    Microsoft has already introduced updated drivers into the NT source
    pool that does the same.  However, it's likely that MS's DEFEA.SYS and
    DEFPA.SYS drivers are still labeled "v1.57" which makes discovering
    the new driver more difficult.
    
    If it's possible, I'd like this report to be updated.  Users shouldn't
    be worried that their DEFEA or DEFPA HW or firmware is bad.
    
    Thanks for posting this note.

    	Hello Larry,
    
    	I do not know who creates the MSKB articles; I believe that it is
    the PSS group in Microsoft.  PSS is their software support group, not
    an engineering group.
    
    	I have informed Microsoft that their article is in error, via
    problem report SRZ 960729-000605.  
    
    	As to a review board:  I doubt that there is any such thing, in
    such a formal sense.
    
    	As always, thanks for your response.

    OK, then I'll suggest the following.  Your group monitors the MSKB
    articles and anything that is Digital NIC related gets forwarded to the
    following folks:
    
    	Mike Paquette (NETCAD::PAQUETTE)	- Adapter Engineering Manager
    	Janice Ferguson (NETCAD::FERGUSON)	- EtherWORKS SW Team Leader
    	Larry Stefani (YESWAY::STEFANI)		- FDDI SW Team Leader
    
    We can then make sure that the articles are accurate, then report back
    to you.
                                                
    Thanks,
       Larry

    	More accurately, we stumble over MSKB articles as customers bring
    them to our attention. :-)  But thanks for the list; I'll use it.
    
    	I have more info on this particular article that I will forward to
    you.
