Previously the foolowing lines would have broken: controller fdc0 at isa? disable port ? bio controller fdc0 at isa? disable port 0x100 bio While this would work: controller fdc0 at isa? disable port "IO_FD1" bio The first of the three lines is useful for making placeholder devices for PCMCIA-floppies, and the second is useful for non-standard hardware. The failure is a "(null)" string in ioconf.c that the compiler pukes on. Thanks to: Bruce Evans (bde@freebsd.org)
