Hi, When building kernel with both acpica and fdc at boot time I'm getting: fdc0: cannot reserve I/O port range Without acpica compiled into kernel fdc detects perfectly fine. fdc is defined in kernel config as follows (same as in GENERIC): device fdc0 at isa? port IO_FD1 irq 6 drq 2 device fd0 at fdc0 drive 0 Probably I should specify different port range for fdc... In this case what range? Any ideas? P.S. 4.11-STABLE i386 FreeBSD built on Sun Mar 6 18:38:35 MSK 2005. -ip -- After all is said and done, a hell of a lot more is said than done
