Andres, may I kindly ask one more question, I'm sure after that I'll get it right myself.
See: -------------------------------------------------------- # make ld -Ttext 0xD0200120 -e start -N --warn-common -S -x -o bsd ${SYSTEM_HEAD} vers.o ${OBJS} acpi_machdep.o(.text+0xcf): In function `acpi_sleep_machdep': : undefined reference to `mem_range_softc' [...] # grep -rw mem_range_softc /sys/arch/i386 [...] /sys/arch/i386/i386/mem.c:struct mem_range_softc mem_range_softc; [...] # grep -rw mem /sys/arch/i386/conf/files.i386 /sys/arch/i386/conf/files.i386:file arch/i386/i386/mem.c -------------------------------------------------------- Still I don't know which option/line is missing. There is no such thing as "i386" in GENERIC, from which I derive my config. Thanks in advance. T.
