Intel Smart Response Technology on Elitebook 8570w

Another timewaster: when installing an Elitebook with hybrid SSD/harddisk storage from scratch, do not install the latest version of Intel Rapid Storage Technology (aka RST or RSTe). It won't show the 'accelerate' button for some reason, no matter what you try. Install the one provided by HP, which is an older version. (11.1.5.1001 in my case). That's all for now.
