I am new on this list. I cannot establish a full duplex connection with
my Micronet SP2500KW (Intel/21143) NIC. (works fine with W2K) There is a
Linux 2.0 driver on the Micronet web site http://www.micronet.com.tw for
the SP2500K (w/o Wake-on-LAN). I tried to compile it but im not that deep
into Linux system programming (yet). At the end it compiled (having
modified lots of it) and it established 100baseTx-FD connection but could
not send or receive packets ... so I left it alone.
With the tulip and the de4x5 driver module, autonegotiated connections to
my 10/100-BaseTX Hub, my 100Base-TX Hub and my 10/100BaseTX switching Hub
result in 100MBit/s Half Duplex connections. As autonegotiation did not
get my NICs into Full Duplex mode, I tried to force the adapter to use a
specific mode. Forcing 100baseTx-FD results in 100baseTx-HD working fine,
forcing 10baseT-FD results in 10baseT-HD not even working.
As 100baseTx is working fine, I didn't try to find out about 10baseT-FD.
Next I tried the 0.92t driver which was supposed to fix my problem, but it
does not, see logs below. Now, I'm contacting the list hoping Don or any
other folks want to suggest what to try next.
My box is a IBM 6x86MX/233 running SuSE 7.0 / SuSE patched 2.2.16 Kernel.

Is there missing any helpful debugging information?
Thank you for any help!

P.S.: 10(0)baseT(x)=10(0)MBit/s over TwistedPair, HD=HalfDuplex, FD=FullDuplex.
OK. What is 100baseFx and 100baseT4?
