1. Create a directory which will be used as gem5 system directory (which
will contain the guest system and boot image). Further called $SYSTEM.
2. Create two directories $SYSTEM/binaries and $SYSTEM/disks.
3. Put guestsystem kernel to $SYSTEM/binaries and boot image to $SYSTEM/disks

3. Put guestsystem kernel to $SYSTEM/binaries and boot image to $SYSTEM/disks.
For ARM targets, you can use the "linux-arm-ael.img" image contained in
http://www.gem5.org/dist/current/arm/arm-system-2011-08.tar.bz2
As an example, the resulting directory structure might look like this
boecke@kos:~/$FAIL_DIR/build/gem5sys$ find
./binaries/abo-simple-arm.elf # your experiment binary (!= gem5)
./disks/linux-arm-ael.img # the ARM image (FIXME: whats this exactly?)
./disks/boot.arm # the ARM bootloader (FIXME: dito)
4. Run gem5 in $FAIL_DIR/simulators/gem5/ with:
$ M5_PATH=$SYSTEM build/ARM/gem5.debug configs/example/fs.py --bare-metal --kernel kernelname
