+Change your ~/.bashrc. After that close all terminals and open a new terminal.
+
+```bash
+# Gem5 SystemC TLM-2.0 coupling (see also: $HOME/gem5_tnt/gem5/util/tlm/README)
+export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${GEM5}/build/X86
+#export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${HOME}/gem5_tnt/gem5/build/ARM

+
+Change the architecture in [DRAMSys/gem5/gem5.pro](DRAMSys/gem5/gem5.pro).

+```
+gem5_arch = 'X86'
+```
+
+Make sure you have built **gem5/build/X86/libgem5_opt.so**. If you build with
+[gem5.TnT] you can check if the library exists as follows.
+
+```bash
+$ ls $HOME/gem5_tnt/gem5/build/X86/libgem5_opt.so
+```
+
+Build DRAMSys as usual.
+
+After building, go the the folder where *DRAMSys_gem5* is located.

+Test with a hello world application for X86.
+
+```bash
+./DRAMSys_gem5 ../../DRAMSys/library/resources/simulations/ddr3-gem5-se.xml ../../DRAMSys/gem5/gem5_se/hello-x86/config.ini 1
+```
+
+A **Hello world!** message should be printed to the standard output.
