+Introduction
+============
+
+The qemu_hppa_b160l_defconfig is meant to run Linux on a HP Visualize B160L
+PA-RISC Workstation[1], emulated with Qemu.
+
+Building
+========
+
+  $ make qemu_hppa_b160l_defconfig
+  $ make
+
+Generated files under output/images:
+
+* rootfs.ext4: the root filesystem.
+* vmlinux: the Linux kernel.
+
+Running under Qemu
+==================
+
+Run the emulation with:
+
+  qemu-system-hppa \
+      -machine B160L \
+      -append "rootwait root=/dev/sda" \
+      -hda output/images/rootfs.ext4 \
+      -kernel output/images/vmlinux \
+      -nographic \
+      -smp 2 # qemu_hppa_b160l_defconfig
+
+The login prompt will appear in the terminal that started Qemu.
