Problem installing PC-BSD 10 cd9660 ... PCBSD_INSTALL failed with error 19

[Quartz]

Although PC-BSD is FreeBSD under the hood they do different things with 
their installer so I'm not sure how much people on this list will be 
able to help you.

IIRC, older/some versions of grub never got around to natively 
supporting usb, and so you need to go into your bios and set legacy usb 
mode to emulate a PS/2 keyboard.

...unless you already did that, in which case I'm out of ideas :)

If the latest PC-BSD installer is anything like FreeBSD's you're not 
supposed to be editing any file, but rather passing options to the boot 
process directly on a sort of command line.
