is enabled by having an "device ed0 at isa? [...]" config line. The first PCI card will get a unit number one higher than the highest defined for any ISA card of the ED type, e.g. if ed0 and ed1 are configured, then the PCI cards will be ed2, ed3, ... BEWARE: If you have configured your kernel as ed0 with the port address as assigned by the PCI BIOS, then your card will be found by both the PCI and ISA probes, and bad things may happen. Make sure to restore the original port address form the GENERIC kernel for the ed0 device! Reviewed by: davidg
