I broke out a really old card to make a cheap solution work, and
now I'm confused. It's an old 3c509 ISA card, which has been set
to 0x300, irq 5. Those don't conflict, so no issue there.
Building a kernel with "device ep0" found it, but didn't like it
because it wasn't at the default IRQ 10. So, I rebuilt a kernel
with
device ep0 at isa? port 0x300 irq 5
Here's where my confusion came in, I get this in dmesg:
ep0 at port 0x300 irq 5 on isa0
ep0: Ethernet address 00:20:af:6a:d8:d6
ep1: <3Com 3C509-TP EtherLink III> at port 0x300-0x30f irq 10 on isa0
ep1: No irq?!
ep1: ep_alloc() failed! (6)
device_probe_and_attach: ep1 attach returned 6
ep0 seems to work ok, and there is no ep1. I'm not sure why it's
auto-looking for an additional card. If I leave the 0 off:
device ep at isa? port 0x300 irq 5
config barfs, even though the default is "device ep".
I get the feeling that if I set this via config I'd be ok, but I don't
have easy access to the console of this particular machine.
I'm sure I'm missing something really simple, but how can I set
ep0 in the kernel config and not get an ep1 along with it?
Alternatives (eg, loader.conf or something) would be fine, I know
nothing about that.
