>Description:
My machine has two network cards in. One SMC Elite 16C (using the
ed driver) and one 3COM 3C509 (using the ep driver).
The kernel config lines for these two devices are
device ed0 at isa? port 0x380 net irq 15 iomem 0xd8000 vector edintr
device ep0 at isa? port 0x300 net irq 3 vector epintr
Those are the correct irq and port values for the cards, as set
using their respective DOS setup programs. Where applicable,
plug and play is turned off.
With this configuration, at boot time ed0 is successfully
recognised.
ed0 at 0x380-0x39f irq 15 maddr 0xd8000 msize 16384 on isa
ed0: address 00:00:c0:dc:5b:ab, type SMC8216/SMC8216C (16 bit)
However, ep0 is not,
ep0 not found at 0x300
If I boot with -c, and tell the ep driver to pick up the port
address from the card, with
port ep0 -1
then it is successfully found. At 0x300!
1 3C5x9 board(s) on ISA found at 0x300
ep0 at 0x300-0x30f irq 3 on isa
ep0: aui/bnc/utp[*UTP*] address 00:20:af:5b:9a:03 irq 3
This is somewhat confusing. This problem persists if ep0 is the
only network card in the machine. I have not been able to confirm
whether this occurs when the card is on other port addresses,
but it does happen on other IRQ settings.
>How-To-Repeat:
Boot a 3C509 network card at port 300 with that port referenced in
the kernel configuration.
>Fix:
Tell the driver to pick up the base address from the card.
It may also be possible to use '-1' in the kernel config file,
although I have not tested this.
