1255.0. "DE450 NT4.0 Driver on ALPHA 1000A" by SUBSYS::HOPEWELL (StorageWorks for PC Lans) Wed Jan 29 1997 12:25

I had a problem with the DE450 on Alpha 1000A with NT4.0. When I installed
NT40 I picked the DE450 EtherWorks Turbo PCI Adapter from the list and NT
loaded the DC21x4.SYS driver from the NT40 CD. I networked the 2 systems
together by themselves using the thinwire connection with autosense. After
install TCP I had trouble pinging each other. I kept getting intermittant
timeouts. I also could not copy large files (18 or 25MB) between the 2
systems without losing the network connection.

I got the DE450 V253 kit off the net and installed it. I noticed the driver
is now called DE450.SYS. After installing this driver everything worked.

    The DE450 driver that ships with NT is owned by Microsoft (dc21x4.sys).
    You can report this bug to them.
    
    The DE450.sys driver that you pulled is written by the adapter
    group, and it is really good news that it fixed the problem!

	Hello, 

	What driver is certified with WindowsNT V4.0 HCT ?
	Is the driver dc21x4.sys in WindowsNT V4.0 HCL, de450.sys ?
    

	Regards

1255.3Is there a new driver for De435MSDOA::JDICKERSONThu Jan 30 1997 09:3721
    Mark,
    
    Thanks for the pointer from the windows-nt conference to here. Note
    5611 in windows-nt and note 1244 in etherworks both pertain to this
    problem. "The web" is a pretty big place. Could you narrow the source
    down a bit? I looked at our ftp site for mumble-mumble /pub/adapters. I
    can find no new driver for the De435, but your problem seems a lot like
    mine. 
    
    I am trying to escalate now, although it is difficult as the
    noted::etherworks response is escalate to the decwet::windows-nt
    conference and the decwet::windows-nt conference response is to
    escalate to noted::etherworks conference. Both conferences urge me to
    escalate to Microsoft, but can provide no means or instruction to do
    so. I really don't want tp pay Microsoft $150 to tell them they have a
    problem I have already e-mailed them and that is all I can do at this
    time.
    
    Thanks for verifying that it could be a driver problem.

    dc21x4.sys is in no way the same as de450.sys.
    
    dc21x4.sys is a generic driver, originally written by Digital
    Semiconductor, to run on all of their ethernet/fast ethernet
    controllers for PCI (21040, 21041, 21140, 21140A, 21142, 21143
    ... so far).  since these are GENERIC drivers, they SHOULD run on 
    our adapters that use these controllers (DE450 uses 21041).
    However, apparently this driver has the bug described in this
    note string.
    
    de450.sys will load and run ONLY on the de450.  This driver is writtem
    by the network adapter group.  Apparently, we do not have this particular 
    bug in our driver.
    
    we did NOT write our own driver for the de435 (21040) for nt.
    we rely on the generic dc21x4 driver within the nt CD to work.

    Thanks for all the suggestions. Finally found someone at NT
    engineering. They have the problem on 3 other sites and were looking
    for a work-around. Now, they have it.
1255.6The alpha "hang" problemJEREMY::CLAUDIOMon Feb 03 1997 03:569
I am the developer of the dc21x4.sys driver at Digital Semiconductors. I got a
mail from Joel pointing me to this conference's notesfiles. I'll start working
on this issue, trying to reproduce the problem with the machines we have here (I
have not such ALPHASERVER machine here :-( ). I'll inform you when I find
something.

Claudio,

Could you please place any updates / information on this problem here 
as well. A few of us are waiting ... holding our breath, for a fix or 
a workaround.

We seem to have seen this (or similar) at a few of our customers 
sites

Thanks,

Greg Harkness
