Hello,
Well I was running a different linux distribution when it worked.
For some of the linksys cards they provide a linux driver but you need
to compile the kernel to use it. I got the Xircom for the OS/2 support
and the PCMPC200 was put on the backup pile. I tended to like Linksys
for their OS/2 support but they did not bother for the PCMPC200.
Cardbus support for OS/2 is "fuzzy". There are Cardbus drivers but
Xircom uses a separate enabler/driver.
Unfortunely I am not using OS/2 as much because IBM is shutting off updates
and improvements to people who do not have a subscription. Linux has filled
the gap.
So I can get the PCMPC200 going but it is like 47th on my to-do list. I
doubt
I would do it unless my Xircom fails. Also I do not run FreeBSD so I do not
know the driver state. I think posting on a FreeBSD list is a good idea.
As to the other observations I can comment that I have seen differences
between windows and linux performance. It is due not only to the NIC
card but also the drivers, TCP/IP stacks. and applications. I have seen
comments that some parameters in Windows TCP/IP may need adjusting in
certain conditions. It may be possible to do some tuning to improve
performance. I find that the http://www.practicallynetworked.com site
gives some good information on networking.
I am happy with the Xircom card and for my non-cardbus machines a
3com 10/100 card and Linksys PCMPC100 card. I had to tranfer files from
a sick 365XD to the backup 365X. I did it over the network and the file
transfer was faster than a parallel laplink cable 8->.

Hello Eric and the Thinkpad list:
Pretty interesting that the Linksys PCMPC200 is no longer working
but was working before. I think some Xircom's had their own chip in it
and some had Intel's 8255x chip in it. I think the Intel and IBM versions
of the RealPort card are identical to the Xircom ones. What's extended
passive mode and also were the speeds the same when you tried initiating
the ftp session on the Windows machine to the Linux machine since for some
reason, for FreeBSD atleast, the if I ftp from the FreeBSD machine to the
Windows box and send/receive, it's 6.4MBytes/sec or about 50Mbps. But if
I did ftp from the Windows machine and send/receive, it's 3.2Mbytes/sec or
about 30Mbps or so. When I meant ping times, I wasn't talking about ping
times on the LAN since all of mines are under 0.10ms through my HP
ProCurve 4000M 40 port 10/100 managed switch. I'm talking about the DSL
Router on the other side of my DSL connection at the ISP since the latency
is 5-6ms more from a Windows machine than from the FreeBSD machine. Here
is a message I posted yesterday on the FreeBSD Mailing list. I bought the
LinkSys PCM200, NetGear FA511 and the Siemens/Efficent Networks SS1012.
