5970.0. "Madge Card on Token Ring in NT 4.0 Alpha" by ZPOVC::LAICHAN () Wed Apr 30 1997 05:54

    Hi there,
    
    We have a customer site with Alpha 4100 5/400 configured with both fast
    ethernet (DE500) and token ring (Madge) with SPX/IPX as the protocol.
    The system is running NT V4.0 with SP2.
    
    We've encountered a strange problem when we try to move or copy files
    over the network. It always give problem while copying big files that
    there is error reading source file. The frame size of the Madge is the
    default 4096. We've to keep trying many times before such big files can
    be copied over the network (ie from a netware file service to the Alpha
    server. We've tried to copy such files from the same file service to
    another Compaq server running OS/2 and we did not encounter the same
    problem.
    
    We are not sure if there is any parameters to set for the Madge card.
    Can a busy network cause such a problem??? What we cann't figure out
    why after trying many times the copy can be done with the same setup.
    
    Appreciate any feedback, pointers and info.
    
    Thanks a million.
    
    Regards,
    Lee

    Re .0, could you tell us more about the Madge adapter itself?
    
    Of course, i'm assuming that you've ensured the symptoms were isolated
    to only when the traffic indeed made it over the Madge TR link.   What
    was the file size when you noticed the problem?

    Re .0, could you tell us what is the buffer count values of the Madge
    adapter from the network control panel adapter tab?

5970.3What should be the buffer count values??ZPOVC::LAICHANThu May 01 1997 09:1121
    Hi,
    
    Thanks for the replies.
    
    The file sizes that gave problems are bigger than 12 MB with some of
    files bigger than 50 MB.
    
    I do not remember the buffer count of the Madge adapter. I'll check for
    on this when I go to the customer site tomorrow (S'pore time). What
    should the buffer count values be so I can change the parameters
    tomorrow. 
    
    We've checked the traffic handled by the Madge adapter to be around
    30%. 
    
    Appreciate your assistance.
    
    Thanks.

5970.4We are still looking for the basic informationDECWET::VOBAFri May 02 1997 10:047
    Re .0 & .3, could you tell us ...
    
    What model is the Madge adapter?  What (PCI/EISA) and which (0/1/2) bus
    it was installed on?  What version of the Madge driver was configured
    for the card?
    
    --svb
5970.5Any more parameters for such a problem?ZPOVC::LAICHANSun May 18 1997 20:2916
    Hi,
    
    The card is Madge Smart 16/4 PCI Ringnode (BM) 2. We've tried the
    various buffer sizes, 4, 6, 8, 10, for testing and also change the frame 
    size from the default 4096 to 2168. The customer told us that they've 
    tried frame size 2168 in other Compaq servers and it seems to be working 
    fine. However, after changing all these parameters we still can get the
    problem resolved.
    
    What could possibly be the cause to just a simply file copy or moving
    of files be?
    
    Thanks.
    
    Regards,
    Lee

    Re .5, i'm sorry it took this long to establish the Madge card in
    question to be a PCI BM adapter.
    
    The only cause that i've seen for the behavior(s) the customer has been
    experiencing is due to the fact that they may have purchased an early
    spin of this adapter model.  This spin of the adapter has a PCI bug,
    discovered at DECwest and has been fixed since then.
    
    Madge has respun and released a newer version of this adapter.  Please
    have the customer contact Madge for a replacement unit.

5970.7Recommended rev?MSE1::MASTRANGELOFri May 23 1997 07:153
    
    What is the new rev of the card that should be recommended to customers
    who are also having problems with the Madge card?
5970.8rev 151-100-04KOKY::PEREZMon Jun 02 1997 08:2925
    A note that I recieved from David Fieldhouse at MADGE says that the
    current version is 151-100-04. This node dates Feb 20, 1997.
    
    .......
    
     FYI, here's a summary of what we're currently recommending:
    
    PCI - board rev. 151-100-04. This is now shipping in bulk, and has 
    replaced the previous -03 revision.
    EISA - standard product (52-08). PCI is recommended in preference to 
    EISA, where possible.
    Driver - mdgmport.sys v2.16 (Alpha) 
    
    Regards,

    Re .8, Ozzie - the latest one is at higher rev.
    
    Re .7, the best way to tell the difference between an old board and a
    fixed board is to look at the Board Number etched into the PCB blank on
    the back of the adapter.  New fixed cards are 150-101-05 and older
    boards are 150-101-02.
