-This little documentation explains how to build a kernel and a rootfs
-for qemu with sh4 architecture.
+Run the emulation with:
 
-1) Select qemu sh4 configuration and compile it :
+  qemu-system-sh4 -M r2d -kernel output/images/zImage -drive file=output/images/rootfs.ext2,if=ide -append "root=/dev/sda noiotrap"
 
-make sh4_defconfig
-make all
-
-2) Run qemu-system-sh4 with the kernel and rootfs previously generated
-
-It's recommended to use a git release for qemu (the current stable
-version has framebuffer display issues). If you want to avoid building
-all target, you can use this option on qemu configure :
---target-list=sh4-softmmu
-
-The command is :
-qemu-system-sh4 -M r2d -kernel output/images/zImage -drive file=output/images/rootfs.ext2,if=ide,format=raw -append root=/dev/sda console=ttySC1,115200 noiotrap
+The login prompt will appear in the graphical window.
