Besides sleep, multi-touch, SD card reader, VGA, and HDMI output not working. I am happy with my 2 E6420 hackintosh results. I did tried one SSD drive and result is the same. I have written a user guide if you are new to this and want to do it, let me know, I will send it to you.

Multi-touch does not work, the gestures is not known, plus the setting is not there under trackpad.

I finally got the dsdt to work by reloading [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] on my E6420 and copy to /Extra, now restart/shutdown works just fine.
