Kevin,
The behaviour of the latest block branch is indeed different, but not
much better.
In my quick manual test, booting via a FreeDOS floppy image:
* latest master: does not seem to read the floppy at all
* latest block: reads the floppy only to the point that 'FreeDOS' is
printed in the console
All other qemu/qemu-kvm versions tested (for example 0.15.0),
successfully read and boot the same image.
CR.
