Of course but it didn't help that I hope I didn't missed something all steps I followed are as follows: # cd /usr/src/sys/powerpc/powermac # fetch http://people.freebsd.org/~nwhitehorn/atamodesetup.diff # patch -p0 < atamodesetup.diff # cd /usr/src # make buildkernel && installkernel The symptom is still same with the previous that it looks no progress. regards, Weongyo Jeong
