Enable CD-RW in FreeBSD

Execute browser and open file:///usr/share/doc/handbook/creating-cds.html.

After customize my FreeBSD kernel, I can't write to my CD-RW, what happen? I need to recompile my kernel with these extra lines in config file:

device atapicam
device scbus
device cd
device pass

Argh... this second time I'm pulling my hair finding why my OS don't like CD-RW.
