Look at /sys/pci/if_ed_p.c and you'll see a list of known card IDs. Add your card to that list. Just because the probe reports that the card was found on the ISA bus doesn't mean that you're not getting the full PCI preformance. The driver can't tell where the card really is, it's the motherboard hardware that knows to use the PCI bus. BTW the real driver is /sys/i386/isa/if_ed.c anyway. --- Gary Jennejohn (work) gjennejohn@frt.dec.com (home) Gary.Jennejohn@munich.netsurf.de (play) gj@freebsd.org
