You're welcome Ryan. Glad you like it.

As to your other option, it is already the case that the APM bios sends 
the shutdown command to Qemu by out'ing bytes to a special port, so I 
imagine it would be possible for Qemu to send commands to the APM bios 
in a similar fashion. But, can the APM bios instruct Windows 2000 to 
shut down? I do not know.
