I read up on what the BTX is.  BooT eXtender -- url here
http://www.freebsd.org/doc/en/books/arch-handbook/boot-boot2.html


Long story short, BTX is what brings the PC BIOS/CMOS code execution from
16-bit real mode, to 32-bit protected mode.

I've had repeated problems with name-brand PCs that result in a BTX halted.
Whiteboxes/custom builds tend to work the best (and IMHO, last the longest).



So asking the OP to flag slices or bsdlabels as bootable probably won't
help, but I've been wrong before.  :D
