963.0. "ATM750 in DEC3000" by KERNEL::GRIFFITHSJ () Tue Jun 03 1997 07:44

    Hello 
    
    
    Could someone confirm the situation with ATM750 in DEC3000-300
    systems. I have read in other notes that it is not supported but docs
    shipped with module say it is with motherboard rev F.
    Alpha is running V7.1
    Does it work.?

963.1Supported but UNIX only.SMURF::GREBUSDTN 381-1426 - Digital UnixTue Jun 03 1997 14:0911
    According to the hardware folks, ATMworks 750 is supported on all revs
    of DEC3000-300, but UNIX only.
    
    That may be all "supported" revs, as we've seen the adapter
    fail to work on at least two Pelicans that were probably proto or early
    production revs.
    
    It works fine on the DEC3000-300LX (Pelican+).

It is in the SPD for V7.1 and from the [OpenVMS V7.1/NF] Chapter 3  System

Could someone clarify?

963.3Not supported on OpenVMSSTAR::DUFFELLTue Jun 03 1997 17:3514
Jim,

OpenVMS V7.1 does NOT support the ATMworks 750 on the DEC3000-300. The
driver for this device was written to only use mapping registers and the
DEC3000-300 does not support mapping registers.

The V7.1 New Features manual does mention this. However it also states that
the 350 is not supported on the AlphaStation 200 and 400 series....which is
not true. The 350 is supported on the AlphaStation 200 and 400 series. 

Sorry for the confusion. The documentation will be updated.

963.5Always check the SOCSMURF::GREBUSDTN 381-1426 - Digital UnixWed Jun 04 1997 15:049
    The definitive document for answers to "is adapter XYZ supported on
    platform ABC" is the Systems and Options Catalog.  It lists
    which adapters the platform qual group has formally qualified.  Even
    though the operating system SPD may list adpater as supported
    by the OS, there may be performance, mechanical, power, etc
    reasons why it is not supported on a particular platform.
