I just finished the installation of my 3Com905B card on Linux 5.1, seems to
be the same configuration (except maybe H/W)  Anyway, I got almost no
trouble from detecting it with the stock kernel.  I did upgrade the kernel &
driver to 2.0.35 and 0.99F.

I don't think you need any options for card detection, that is no IRQ, no DMA,
and no I/O.  However, you do need to specify 'options', for example under my
situation, I have /etc/conf.modules set to:


     alias eth1 8390
     alias eth0 3c59x
     alias eth1 ne2k-pci
     options eth0 options=4


Also, if your computer has multiple card, you also need to add another file
in the /etc/sysconfig/network-scripts/, just duplicate the ifcfg-eth0 and
name the new file as ifcfg-eth1 and modify the entry of it (it is plain text)

After that I don't see you should be done.  Oh, BTW, if you install the new
kernel, it could happen that there is chance the IP_FORWARD is being dis-
abled at RUNTIME (even you specify CONFIG_IP_FORWARD at compile
time).  Just modify the /etc/sysconfig/network file to switch that back on
again.

One more thing, even I get my 3Com card running, it is still not very stable.
It seems that it will eventually crash and lock up my machine, especially
when I am transferring large file, such as 50MB, 100MB ...  My H/W config
is the following:


     AMD K6-2 300
     Acer 59Pro
     Cirrus Video Card
     2 X Acer ALN-201 (run vnc smoothly even they are 10BT)
     Western Digital HD

The same config run stably on NT4 (I only tested that for about an hour)

I have a ethernet 3c905b card, and have just installed redhat linux 5.1.
After the auto probing during installation
redhat said it found a Vortex card 3c9x or something, but I have a 3c905b
and it seems that it is not compatible with
whatever redhat found. I tried redhat support, but they were not helpful at
all, after asking them the same question 3
times I got 3 different answers, none of which could help me.

So if someone can tell me axactly step by step how to get my ethernet card
working, Id be very happy.
Also please explain how I can find the i/o and irc or dma numbers for my
cards. I also have an 3com 3c509
card installed, if this should prove to be easier to install please tell me
how to :)

Ive tried man modprobe which was what redhat said I should do, but I
couldnt figure out how the command worked nor how to
find the i/o, irc and dma stuff that I needed..

Some one pleaseeeeee help me...Im going loco
