1072.0. "Technical details about FDDIcontroller/EISA" by MUCCS1::SIMADER (One of the Austrians in Germany...) Thu Aug 26 1993 06:34

    
    Who can tell me the answers for 4 very simple questions concerning the
    FDDIcontroller/EISA:
    
    1. Which interrupts can be selected ?
    
    2. Which DMA-channels are available ?
    
    3. How big is the on-board buffer ?
    
    4. Why is such information not in any product information ( Network
       Buyers Guide, SPD of microcode ... ) - the customer is asking for
       this to be able to plan his PC-configuration.
    
    I need this information very quickly !
    
    Thanks Helmut

    >>1. Which interrupts can be selected ?
    
	9, 10, 11, or 15
        
    >>2. Which DMA-channels are available ?
    
        None.  The DEC FDDIcontroller/EISA uses on-board DMA (a competitive
        advantage over slave-DMA).
    
    >>3. How big is the on-board buffer ?
    
        1 Megabyte of packet memory for incoming/outgoing frames. 
        According to a recent PC Week article, we have much more buffering
        than our competitors.
    
    >>4. Why is such information not in any product information ( Network
    >>   Buyers Guide, SPD of microcode ... ) - the customer is asking for

        Good question.  I'll forward this note to the PM (Sharon Oneill)
        and my supervisor so that this can get corrected.
    
    >>I need this information very quickly !
    
        Quick enough?  I just got in!  :-)  :-)

    Yes, Larry, it were exactly in time and that's great !
    Thanks a lot for your support.

1072.3DOS/RMX is supported ??TAV02::KATZAVWed Dec 01 1993 12:0411
    
    Does the FDDIcontroller/EISA run under DOS/RMX ??
    
    A customer with heavy developed software under dos/rmx would like to
    connect via FDDI to Alpha server. Is it supported?
    (They need API interface for the driver that can coexist with RMX)
    
    
    Thanks,
    
    Shimon.

    >>Does the FDDIcontroller/EISA run under DOS/RMX ??
    
       I need to have a better idea of what DOS/RMX is.  We supply NDIS and
    ODI drivers to allow the DEFEA to run under DOS using most popular
    protocol stacks and networking software.  Does this DOS/RMX software
    run on top of generic NDIS or ODI drivers?  If so, then it's likely to
    be already supported.  If it requires a special driver, then its not
    likely to work.
     
    >>  (They need API interface for the driver that can coexist with RMX)
    
    I'm not sure what this would entail.  Could you provide some more
    specifics?  We do have an internal specification that defines the port
    interface to all of our third-generation FDDI adapters.
