I just tried to run WXP on OPI ONE in a qemu emulation. It is dead slow due to x86 emulation and running on one CPU. Please provide specifics on how you did run WXP in qemu on OPI PC using more than one CPU. Or did I just not get the joke ? The only sensible way of running WXP on OPI is by using it as a thin client to connect to a running physical or virtual WXP installation on X86.
According to Arm and Windows too, they still have major problems and cannot support or use on Windows 10 for Arms. Moreover, you now insisting that you are running Windows XP on Arms processor.
