Reinstalling PC-BSD w/ mirror raid.
The first time I installed PC-BSD on my desktop I used the mirror raid option from the raid utilities to use sata0 to mirror onto sata1. I since hosed my installation and decided it was best to do a fresh install, I was hoping to leave the partitions and existing files, but the graphical installer would not start until I ran the raid utilities build mirror raid again. After destroying the existing raid and creating a new mirror the graphical installer started and allowed me to reinstall. This could have been a mishap on my end but if someone else could confirm this then it should be fixed in the next release.
