I'd propose that cbus implements the ISA > interfaces in a similar manner. If my understanding is not a mistake, the CardBus specifications is derived from the PCI. Therefore, I can understand that the cardbus driver depend on the pci driver. But, the Cbus is NOT derived from the ISA. So, I think that the cbus driver should not depend on the isa driver. --- TAKAHASHI Yoshihiro <nyan@FreeBSD.org> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
