Mulitple 3c509 cards 2.4.x Kernel

Mulitple 3c509 cards 2.4.x Kernel

[Paul]

I have a x86 server with multiple(2) 3c509 cards. When I build the 3c509
driver
into the kernel. It will only pick up a single card. The cards are
NOT in pnp mode
according to isapnp on boot. I have added:

append = "ether=3,0x300,0,0,eth0 ether=10,0x280,0,0,eth1"

to the lilo file and still only one card is detected. The io ports and
irq's come direct
from /proc with  the 2.2.13 kernel in place. There are no messages about
anything
failing, only the message that the one card was found. It appears the
card on the
higher io(0x300) is the only one that is ever found.

The machine is an old p100 with no no other cards except the video card.
I have
tested this with every kernel from 2.4.0-testxx to the 2.4.6 kernel. I
see nothing in
the changelog for 2.4.7 that leads me to believe it is fixed in that
kernel.

Please CC me on any reply or request as I am not a member of the list.

Thanks,
Paul Stroud

Did you configure your cards (ie. IRQ, IO) using DOS driver or
'3c5x9setup.c'?  It could be that they are both waiting at the same
default irq/io.

You should use 2.2.19 nowadays. 2.2.13 is insecure.

Are the cards themselves in ISAPNP mode or in fixed-address/IRQ mode?
Linux 2.4 has ISAPNP capabilities if you choose so at compile time,
these might move the card. Check your boot logs and /proc/isapnp and
/proc/sys/isapnp.

Did you re-run lilo?

The 3c509 is an anomaly in comparison to other ISA cards, in that
you DONT want to specify I/O (or irq) values.  3Com used a scheme that
allows relatively safe ISA probes, and specifying an I/O base will
do nothing but interfere with that.  (This is documented btw)

In your case, a simple

append = "ether=0,0,eth1"

should do the trick (assuming the ether= parsing is currently 
functional... :)

Both cards were configured as non-pnp to use the irq/io mentioned
earlier(10,0x280,3,0x300).

The ether fix did not work.
dmesg shows no isapnp devices found.
/proc/ioports and /proc/interrupts show the card
that is found and that the other ioport and interrupt are
unused.
