I'm not well versed in qemu's various options. When I didn't specify a BIOS image, it seems to be using SeaBIOS, not UEFI, and hangs on "Booting from Hard Disk...". I should be able to start doing proper videos soon; I've been slowly working towards that.

I can say that the display & overall performance is noticeably faster on the two actual computers I tested on than under qemu on my Linux system.
