1232.0. "Alphastation 500/500 and 3d30 support" by AUBER::TISSERAND (Jean-Marc Tisserand, French CSC, 858-6801) Mon Feb 03 1997 06:36

Hi,

A customer of mine is using a 3D30 board in an alphastation 500/500 with Unix
v3.2d and Open3d v3.3

He enountered 2 problems. The first has been fixed by using the ffbDoDMA flag.

The second one is still there.
When moving a window on the screen, there are some garbage that remains where
the window was before the move.
The user is also seeing small horizontal lines drawn in windows, for example in
the dxconsole scrollbar.

Disabling saveunder, backingstore, dma write does not help.


Looking at the Open3d v3.3 and v3.4 spd, I found that the Alphastation 500/500
is not supported. The supported platforms are the Alphastations 500/266, 500/333
and 500/400.

The customer system was running fine with Unix v4.0a. The customer downgraded
to Unix v3.2d to have the same version on all systems. The Alphastation 500/500
seems to be supported with unix v3.2d.

With unix v4.0a, sizer -gt gave zlxp2-ev5
With unix v3.2d, sizer -gt gives zlxp2-ev4.

Does it mean that the board is not well recognized by open3d (maybe due to the
fact that the alphastation 500/500 is not supported by open3d v3.3, v3.4) ?

Do I need some special files to make the 3D30 correctly working and to support
the Alphastation 500/500.


Thanks in advance for any input.
Regards,
Jean-Marc

    The AlphaStation 500/500 is an EV56 device, not an EV5 device.
    
    It looks like the Open3D 3.4/UNIX 3.2d code is not recognizing
    the CPU correctly and is giving you EV4 code for this device.
    (Just a guess.)  Since the device was not listed as supported
    for Open3D v3.4, it is certain that it was never tested on that
    workstation.
    
    You say the AS 500/100 "seems" to be supported by UNIX 3.2d; is
    that what the SPD for that version of UNIX says?  Is it really
    supported?
    
    Always better to use a configuration that was tested before the
    software was shipped.
    

I found the information that as 500/500 is supported by unix v3.2f, v3.2g.
