Linksys Etherfast PNIC card works... but only in Linux??

Tue Dec 1 10:39:32 1998

Hi all,

this isn't a Linux bug report, but a question because my Linksys
Etherfast 10/100 PCI card (PNIC chip) *does* work in Linux.  I've got a
Am5x86-133 with a VIP (M919) motherboard with 32 MB, triple booting into
Linux, Win95, and DOS 6.22/Windows 3.1.  To my surprise, it was
reasonably easy to get the Linksys card working under Linux (RH 5.1);
I'm now using the 0.90 driver without any problems.

But my problems come in the unexpected place -- I can't get my card to
work properly under either DOS or Windows 95!  Normally, I wouldn't post
to the Linux group about it, but I'm hoping someone here can decipher my
problems in a way that will help me figure out whether mine is a
hardware issue or a software issue, and if there's a way to resolve it.
Linksys tech support was clueless and no help.

Under DOS or Win95, I have no problems with loading the driver for the
card, and there's no indication of any problems with the TCP/IP stack or
anything.  But when I try to do a ping of another machine on our
intranet, nearly all my outgoing packets seem to get truncated somehow
(Win95 ping says "Request timed out").  I am reasonably sure it's not
the card itself, as I've tried swapping it with another Linksys card,
and it *does* work in Linux (hence my hope that Donald or someone else
can provide insight here)... I've included the log below of tcpdump.
Can anyone suggest anything?  I'm at the end of my rope, trying to
decide whether to return the card (15% restocking fee) and get a
different brand or what.  =(

Thanks,
Eric

here's the tcpdump log.  my machine's IP address is 10.0.0.3, the other
machine I'm pinging is 10.0.0.1.  the first part is when my machine's
running Linux, the second part is under Win95.  My netmask is
set to 255.255.255.0.
