+: emulating windows xp on a raspberry pi
+
+https://computernewb.com/wiki/QEMU/Guests/Windows_XP
+
+I'm going to assume you have qemu installed, and the binaries
+qemu-system-x86_64 and qemu-img in your PATH, and a Windows XP x64 installation
+disc image as winxp.iso.
+
+$ qemu-img create -f qcow2 winxp.img 20G
+
+This will make a qcow2 disk image for qemu. It grows as Windows writes to it so
+you don't have to be miserly with your bytes. I will not come close to filling
+20GB. On my machine the created file is 196K.
+
+$ qemu-system-x86_64 \
+	-m 1G \
+	-device VGA,vgamem_mb=64 \
+	-cpu qemu64 \
+	-M pc \
+	-netdev user,id=lan \
+	-device rtl8139,netdev=lan \
+	-usb \
+	-device usb-tablet \
+	-rtc base=localtime \
+	-monitor stdio \
+	-cdrom winxp.iso \
+	-hda winxp.img
+
+Have fun.
