@john34 The bios has SLIC 2.0 which is good for activating Vista but not for 7. You need to request the Phoenix bios mod section for a mod.
I tried on my ASROCK Q1900-ITX motherboard with official BIOS version 1.40 flushed and then patched with the Dell SLIC 2.3 provided. And it WORKS! Now I can activate Windows 7 and Windows 2012 R2 on this motherboard. Tested and works flawlessly. Thanks Make sure you follow the steps as stated before patching......
