Sorry for the inconvenience.  Known Navigation header breakage of “Previous:” and “Next:” links, the Table Of Contents may be the solution for those.
However, unfortunately, the Table of contents may also be broken, and there may be other unforeseen breakage primarily in the handbook portion of the wiki.
Presently the 10.1 and 10.1.1 Table Of Contents are being "reconstructed" becoming incrementally fixed while the other handbook versions may have various breakage.

The option to install a boot loader during PC-BSD installation is no longer present in the GUI, hence the mods to the discussion around recovering from "accidental use" of that previously available option.


Unsure exactly how/where to fit this in:

boot0cfg

From commandline:

boot0cfg -B ada0

Grub 2

I noticed the section on Grub 2 is a little out of date. The map command is a legacy command. In Grub 2, it was renamed to drivemap. Also, the device names changed slightly in Grub 2: the partitions of the hard drive are counted from 1 instead of 0: so, (hd0,msdos1) is the first partition of the first hard drive.

drivemap isn't actually needed to boot PC-BSD if it's on the second disk, at least for me. My menuentry is something like this:

menuentry "PC-BSD 9.1" {
insmod ufs2
set root=(hd1,msdos1)
chainloader +1
}
