3Com NIC Driver?

3Com NIC Driver?

[Hal MacArgle]

Greetings: I made the, probable, mistake of buying a 3Com 3C900B-TPC
PCI BNC NIC discovering that the module automatically installed by
Slackware 9.0, 2.4.20 - 3c59x.o - does not ping.. Checking the Web I
find that 3c59x.o is for the 3C900 (no suffix) models and that I may
need 3c90x.o instead..

Downloaded the source for that but it wont compile under Slack9.0..
An attempt to -f (force) using a pre-compiled version didn't work
either..

I may be stuck but was wondering if someone may have run into this
and solved the problem, and/or has a module compiled for 2.4.20..

Rather than go into further details of what I did, suffice it to say
that I swapped a RealTec NIC into the same PCI slot, and it worked
perfectly with the ifconfig and route add entries, so I must presume
the cables, etc are OK.. dmesg listed the 3Com NIC, with the same
IRQ# and Port# that were assigned to the RealTec NIC..

Appreciate and TIA.

Re: 3Com NIC Driver?

[rob]

are you sure that you have the ports,irq,dma,mem settings right ?
have you tryed isapnpdump yet to get the settings for this card?
If you have windblows on this computer you could check the settings  
with windblows device manager
are you useing insmod or modprobe ? (try modprobe)

AFAIK that nic may have needed a module called 3c90x back in 2.0 and 2.1 
kernels, but according to google it now uses the 3c9x module.

Does modprobe return an error when loading the module, the module in the 
bare.i kernel should do ok.
If there is no error what does 'ifconfig eth0' say. (presuming its the first 
nic of course).
What does the command 'route -ne' say.?

Also another helper could be 'mii-tool' (to see the nic's status).

	This was the bare.i kernel, 2.4.20, default install.. The
module was loaded and the NIC card found automatically on boot; the
only entries I made were ifconfig and route add.. See following
script.

	See following script, some snipped to shorten the verbiage.
Only one NIC at a time..

	As I read man mii-tool, I gather it's for RJ45 connections
only whereas I'm exclusively thinnet, 10base2, BNC.. Correct me if
I'm wrong on this..

	Script follows which points to the cables or connection, it
seems, but another different brand NIC, in the same PCI slot, is
found; a different module automatically loaded, and works fine.. Back
to 3Com NIC and a repeat of the problem.. Hopefully you can see
something I'm not familiar with. <grin> Thanks Richard.

Re: 3Com NIC Driver?

[Ray Olszewski]

HI, Hal. Sorry to jump into this one late, but since Richard said he'd be 
away for awhile ...

In checking on the NIC, I notice it is described at several sites as having 
both BNC (thinnet, 10Base2) and RJ45 (UTP, 10BaseT) jacks. And I notice 
that after you ping unsuccessfully, ifconfig reports (in part)

           TX packets:9 errors:0 dropped:0 overruns:0 carrier:9

Taken together, this makes me wonder if the card is set to use the wrong 
port. The docs I found for this card seem to say it comes out of the box 
set for media autoselect, but that's not something I'd rely on. The 
"Destination Host Unreachable" message you get when ping'ing is consistent 
with this guess (though not always present). You might want to get the 
DOS-based setup program for this NIC (or see if Don Becker's released a 
Linux-based one) and check its settings.

And I realize, in rereading your message, that either you've not said 
whether you are using thinnet or UTP with this card, or I missed where you 
told us. Also, just barely conceivably, you've connected it via UTP to a 
switch that does not drop back to 10 Mbps (is the other card you test with 
successfully 10 or 100 Mbps?).

Final thought ... I have a hazy memory of running into some oddball 3Com 
NICs of about the vintage of the one you have. They had problems with 
standard UTP wiring. I forget the details ... except that I ended up 
scrapping the cards, NICs these days being too cheap to spend much time 
mucking about with (especially old, 10 Mbps NICs).

Re: 3Com NIC Driver?

[Hal MacArgle]

Greetings again Ray: I did mention that we were 100% 10base2 here and
had I had a crossover UTP cable to try, would have found the problem
myself..

Your experience let you say the magic phrase: Auto-media on 3Com
cards don't always work - which was the case.. Default 10baseT, I had
to re-flash it with the setup Dos program.. All's now well discovering
that I had been lucky before with my SMC and RealTek NIC's all auto
sensing without my intervention..

APPRECIATE!! Happy Holiday...

Hal

Auto-media is a thing which does not work well on any card in linux (IMHO) 
that is. I used to have such a problem with my SMC cards, i found that if 
there was no signal presant at inititaliation time then UTP would be used.
If the BNC connector is connected to another machine or hub and there is no 
traffic during the init,. process then UTP gets selected by Auto-media, 
however if i setup a ping on another machine and created traffic then 
10base-T would be selcted and the card worked properly.

I tryed the above with realtec 8019 cards as well and got the same results 
which is why i say Auto-media does not work well in linux, but having said 
that i have not tryed any of the cards under windows to see if the results 
are the same so really saying it does not work well in linux is not the right 
thing to say, possably the same problems will arise under windows as well, 
which is possably why all dual cards have dos/windows programs to change 
defaults in the cards chips.

It could also be that some Mobo's are slower in the detection process and dont 
return a value to modrobe quickly enough thus selecting UTP as default, but 
thats a wild guess.

There is another method of selcting 10base-T or UTP when inserting the cards 
module, some cards have module options to select the output, its been a long 
time since i used 10base-T and to be honest i have forgotten which cards have 
what options.
There is a command to show what options a module/driver has,

modinfo -p <module_name>
