-  $ export QEMUSRC=/path/to/qemu/svn
-  $ git clone git://git.kernel.org/pub/scm/virt/bochs/bochs.git
-  $ cd bochs
-  $ git checkout -b qemu-bios $(cat $QEMUSRC/pc-bios/bios-pq/HEAD)

-  $ mkdir -p .git/patches
-  $ ln -s $QEMUSRC/pc-bios/bios-pq .git/patches/qemu-bios
-  $ touch .git/patches/qemu-bios/status
-  $ guilt push -a
-  $ ./configure
-  $ cd bios
-  $ make
-  $ cp BIOS-bochs-latest $QEMUSRC/pc-bios/bios.bin
