 Sorry I think it was supposed to be /wd2  (I'm still new to BSD, I forgot
 the drives started at 0 not A ;)

 This probably would have fixed the problem.  However the installer didn't
 seem to do this automatically, which I would consider a bug.  Everything
 installs perfectly, but the kernel isn't updated with the proper boot device
 I guess. What confused me was the fact that the FSTAB had the proper mount
 points, but when the system booted it had a message:
 
 changing root device to /wd1  (my CD-ROM)
 root FS not found...  (or something similar)

 Nothing special, it's just the generic kernel.  Just learned how to config
 :)
