FreeDOS 1.0	32	kvm-12/14	Intel	64	Work(ish)	Can only be installed from live CD by disabling kvm and using qemu only. Upper memory management (himem.exe) crashed kvm. Some other drivers do so as well. Step through booting using F8 to determine which. DOS is confined to the lower 640K of memory. See bug 1666308.
