I wanted to make a USB flash drive based installer for FreeBSD but=20
unfortunately BTX seems to have issues that make it difficult to do=20
reliably :(

Here are 2 patches I tried..
http://people.freebsd.org/~kib/realbtx
http://people.freebsd.org/~jhb/patches/btx_crx.patch

They improved things but I still found a number of systems where BTX=20
would spin dumping register info so fast I couldn't read it (or take a=20
photo..).

Unfortunately I have no idea how you'd debug this sort of thing, it's=20
too much like DOS programming for me :)

=46WIW when it did work it was great :) I used FreeSBIE as my base - it=20
has stuff to build USB images in CVS (v2). http://www.freesbie.org/

I don't know if it's possible to use GRUB or something like that instead=20
of BTX.. I have no experience with it, but I would be very interested=20
if it did work (although since GRUB is i386 only and I use amd64=20
systems that's another hurdle..)
