Now "drive" access is also implemented. Releated to Qemu that does mean that one can access the host's CD-ROM from the guest OS. Example for Qemu running without image files in DOS:

dpmild32 -g qemu -m 32 -hda \\.\PhysicalDrive0 -cdrom \\.\h:

(H: is CD-ROM of host)

It works reliable after all. That's the good thing of a single-tasking OS like DOS: when Qemu is launched, there are no open files belonging to other tasks, and no danger that those are closed by the OS while Qemu is running. Of course, there remains a small risk, since DOS holds information in its "buffers" and most likely assumes that these reflect the content of the physical disk.
