Three out of four times I had a problem booting PC-BSD. I am not sure if it is PC-BSD specific or Free-BSD as well. The problem appears to be the cd/dvd drive. For someone reason during the boot process it gets confused, says no medium was found and most times it just freezes. So I searched and found the work around is keeping a disk in the cd/dvd drive. This works perfectly. However I would like to find out how to fix this without having to keep a disk in the drive all the time. Anyone have any ideas?
