Ard/Laszlo or anyone familiar with QEMU.

I read up on the ovmf readme and the qemu wiki but still have a few issues i am hoping for quick/easy answers.

1. How do i programmatically exit the emulator.   Seems like uefi shell > reset just reboots.  Other ideas?
2. Is there an easy way to map a local file system so that i can setup a startup.nsh?

Thanks
Sean
